(October 17: I think this is done! I might add one or two stray bonus ideas if something strikes me but all of this should stick.)

Hello creator!

Let me first say you have great taste in fandoms, and I'm excited by everything here, so I really just can't wait to see what you come up with. If my signup gave you enough to go on already, awesome, don't feel bound to include any of the extras here! If you want some of my thoughts on how these ships and freeforms could interact, here they are. It's all optional, it's not comprehensive, and I promise there's no secret "oh they want this request/ship more" meaning intended in the lengths of sections. Please just have fun making someone have a bad time!

General Preferences from Letter

- In general I like my xcon in the "comfortably distant from reality" neighborhood, often with magic and monsters contributing to the problem, and with victims who get turned on and often come despite not wanting to be there.
- If there's a thinking, communicative aggressor (as opposed to random tentacles, etc.), I usually like coercive methods much more than overt physical violence; I'll note exceptions in requests.
- I like a lot of hentai/fantasy porn stuff: heat, sex pollen, cursed-to-crave-sex, and similar compulsions; I like implausible/impossible penetration made possible (and non physically harmful) by magic; I like lots of fluids, including addictive come, aphrodisiac come, and other mind-altering messiness.
- Visually, I like size difference (both dauntingly big aggressors and dauntingly big cocks), lots of blushing, lots of fluids, glazed-eyes too-fucked-head-empty expressions, x-ray detail shots (especially of penetration otherwise not visible), throat and/or belly bulge. Crying if it's a result of choking on dick/tentacles/etc.
- I like endings that don't leave victims in despair—whether because they escape the aggressor, they have faith that they *will* get free even if they haven't yet, or they're brainwashed into wanting more.

General DNWs:
- BDSM being a setup or pretext for xcon
- medical kink, particularly involving speculums, pelvic exams, etc.
- trans characters being victimized; queer characters being subjected to "corrective" rape
- serious or realistic depictions of emotional abuse, trauma, or the effects thereof
- focus on the victim's experience being physically painful, especially painful penetration
- narration, pov, dialogue, or worldbuilding that suggests one group of people (e.g. women, omegas) are destined to be exploited because of their biology
- aggressors being punished, victims or their allies taking revenge
- pregnancy, scat, vomit, force feeding, infantilism and age play, extreme underage (<13)
- time travel, time loops, mundane AUs

Deadman Wonderland

Tsunenaga Tamaki makes Senji Kiyomasa & Igarashi Ganta mxcon
Voyeurism - Others Pay to Watch, Public - Openly Xconned, Public - Xcon In Front of Audience, Recording - Victim Recorded Against Their Will, Sex Work - Forced to Star in Porn, Mxcon - For Entertainment of Third Party, Mxcon - Trying to Be Gentle, Inexperience - One Victim Forced to Teach Other What to Do

The hentai AU where the Carnival Corpse prisoners aren't expected to have bloody fights, they're expected to do fetish sex shows for an audience of wealthy decadents, and it's the debut "bout" for a new young star~

The "rematch" where someone, maybe Tamaki or maybe someone in the audience, wants to see Senji and Ganta put on a different kind of show after their fight! Maybe that's something that's never happened before. But you want your candy, don't you, boys?

Senji hates the idea that he's expected to rape this kid to entertain a bunch of perverts, but if there's no way out of it then he's going to try his best to make sure Ganta comes through it okay.

Ganta is so out of his depth here -- I'd have trouble buying extreme "doesn't know that men can fuck" levels of inexperience, but I'd absolutely believe that not only is he a virgin, he's about to have his first kiss on camera.

If it's a regular feature of the prison, maybe they have drugs or conditioning for lackluster performers, so Ganta faces the choice between acting like he enjoys being railed by dangerous criminals or getting mindfucked until he's not capable of objecting.

Granblue Fantasy 1: Monsters/tentacles

Crimson horizon creatures xcon Beelzebub, Monsters xcon Stan, Otherworld creature(s) xcon Aglovale, Tentacles xcon Beelzebub (GBF), Tentacles xcon Jeanne, Tentacles xcon Katalina, Tentacles xcon Rackam, Tentacles xcon Seofon, Primals xcon Lyria
Xeno, Xeno - Creature Cock, Xeno - Knotting, Xeno - Tentacles, Penetration - In Every Hole, Penetration - Oral Knotting, Comeplay - Addictive Come, Comeplay - Come Inflation, Sex Pollen, Watersports - Victim Wets Self, Scenario - Victim Used Until Limp and Exhausted, Altered States - Dream Sex, Xeno - Victim is Like Catnip to Non-Human Character

Probably my most straightforward request in any of my fandoms. Please make your chosen character a sloppy mess, stuffed full and dripping with come, and possibly fuzzy-headed enough to not remember why that's a bad thing. The rest is details.

That watersports tag: I'm seeing it as part of the sheer excess of being stuffed overfull of tentacles/monster cock/etc.—the pressure from inside is just too much to stand and the victim loses control, to their endless humiliation ♥

Also, "every hole" can absolutely include someone's cock slit if you're into that.

Also, "tentacles" and "monsters" are just suggestions and you should feel free to swap them around—there are a lot of cool monsters and dangerous primals in GBF and if you want to use someone from the game I'll enjoy that detail, but if you want to go with random tentacles from nowhere that's also great. Hotness beats accuracy here.

Otherworld creatures seem to have such a deep need to disrupt Jeanne, messing with her mind, convincing her that she wasn't a warrior after all—what about the version where they're not trying to convince her she's a delicate princess but rather a thirsty tentacle sex slave?

Bubs the great warrior being in bad enough shape when he's tossed down to the Crimson Horizon that he can't fight off its most ordinary denizens? And he's infuriated by the liberties they take? But by the time he's healed from the battle, he's thirsting for more of the come they've been pumping into him?

Stan is such a scaredy-cat early in his arc, but there he is out in the middle of nowhere trying to fight monsters to get stronger! Doing his best! Only this particular nest of monsters don't want to fight. Does that make it better or worse?

Did Rackam or Katalina (or hell, Seofon) distract the terrible monster so someone else would have time to get away? Are they now really hoping that someone will come back with reinforcements before they're so fucked out and sloppy that they forget how to resist?

Seofon getting in over his head is just so hot, ok. Confident in his power, misjudging a threat, and getting so immensely fucked, yes please.

Gaping, dripping holes and glazed eyes and helpless cooperation, very hot. Victim playing with their own junk because the fucking is getting them so turned on they can't help it, unf.

Very optional: if you like rescues, character being rescued by someone who cares about them and it turns out the victim still, in their exhausted and fucked-out state, needs more to help them come back to their senses, and the rescuer has to fuck them too. Any excuse for this is totally fine.

Granblue Fantasy 2: Wanted it but not like this

Any makes Naoise xcon Seruel, Any makes Reinhartzar & Cain mxcon, Any makes Seofon xcon Seox, Siegfried & Lancelot & Vane & Percival mxcon, Siegfried & Lancelot & Vane mxcon, Siegfried & Lancelot mxcon, Onset of Heat makes Scathacha xcon Naoise, Erune Heat makes Seox xcon Feower, Erune Heat makes Seox xcon Seofon, Rei makes Feower xcon Tien, Magic makes Gawain & Florence mxcon, Lucius & Teena mxcon, Baragona Aragon & Halvarda mxcon, Belial & Lucifer mxcon
Character(s) Wanted It But Not Like This, Sex Pollen, Scenario - Unexpected Heat (non-A/B/O), Something Made Them Do It, Something Made Them Do It - Magical/Cursed Item, Mxcon - Mutually Pining Victims Perform for an Audience, Mxcon - Penetrator is More Upset Than Penetrated Victim, Aftermath - Consensual Aftercare After Xcon, Bargaining - Victim Must Convince Unwilling Aggressor to Commit Xcon, Scenario - "You xcon them or I will", Cooperation - For Access to Necessary Item/Information/Assistance, Mxcon - Unaware of mutual attraction

All the complicated feelings! In this request I am here for the characters who are fucking being very fond of each other and struggling with their circumstances. Probably they don't have an existing sexual/romantic relationship but they do have a strong connection.

Sex pollen is great and I'm up for it in any of these ships, whether that's an accident or something somebody dosed them with. I like both "only one affected" and "both parties affected" scenarios; I'm not terribly into situations where one party doesn't know the other's affected but otherwise, free rein.

The extra degree of overwhelmed-and-confused from having heat be first heat is delicious and I'd believe that of any character who's under about 20 or who has a reason to not have been susceptible to heat before now.

Siegfried having some kind of dragon-blood heat, possibly natural, possibly set off by a cursed item (hell, Hagen could have tossed it his way), and one or more of his dearest comrades step in to make sure that no civilians get hurt. They can handle it if anyone can!

Rei is so sure of her power, and so sure she has the right to demand that people prove themselves to her; Feower is furious at the order she gives him, but Tien is already gritting her teeth and starting to unfasten her clothes, ready to go through with it if that's the price they have to pay...

Erune heat ships: I really like the idea of heat making the character aggressive, dangerous, struggling for control of themself and just so hungry, while the target of their attentions really doesn't want to hurt them but isn't sure how to defuse them, either. With Scathacha you get the bonus of her not expecting this, because this isn't her dragon body and she wasn't prepared for how it would behave.

Anal to avoid risk of pregnancy would be a nice bonus in any of the het ships here but especially Lucius/Teena, who have an extra reason to want to avoid it and godDAMN does Teena have a cute fuckable ass.

Given how powerful the characters are, the "Any" in those "Any makes..." ships must be someone pretty dangerous. But that just makes "You xcon them or I will" a more compelling threat, right? Better not let somebody really fucked up get their hands on someone so special...

I've completely fallen for the period where Belial was Lucifer's adjutant and would love a thing with them to be set before the rebellion—maybe they're on patrol somewhere and discover an island with sex pollen, or maybe some new creation from the labs has an unexpected effect on the primal beasts who encounter it...

Gawain and Florence are basically the only line of defense for their country, and there's a ritual Florence has unearthed that would save them from an incoming threat—but she's not sure he's going to like what the ritual requires them to do...

Someone operates an artifact or triggers a trap in an Astral ruin and now they feel sick/weak if they get more than ten feet from the person who was exploring with them, and the feelings are only getting more intense. They have to get closer. They have to be touching. They need so much more than this.

Granblue Fantasy 3: Bad man has good time

Belial xcons Any Teen or Adult Skydweller, Belial xcons Azazel, Belial xcons Michael, Belial xcons Seofon, Isabella xcons Lancelot, Necesaria xcons Gandharva, Otherworld Possession makes Aglovale xcon Percival, Yurius xcons Albert, Vira Lilie xcons Katalina Alize
Attitude - Victim Unsure of Own Consent, Altered States - Nonconsensual Drugging, Altered States - Victim Dosed with Aphrodisiac, Arousal - Aroused Victim, Arousal - Forced to Enjoy Xcon, Betrayal - Aggressor Takes Advantage Of Victim In Predicament With Sexual Undertones, Coercion - Forced to Talk Dirty, Coercion - Illusion of Choice, Comeplay - Addictive Come, Comeplay - Come Inflation, Comeplay - Covering Victim in Come, Magic - Cursed with Constant Need for Sex, Magic - Obedience Curses, Magic - Victim Becomes Addicted to Sex with Aggressor, Motive - Possessiveness, Motive - Public Display of Ownership, Oral - Aggressor Performs Oral Sex, Penetration - With the Hilt of a Weapon, Scenario - Forced to Live Out Darkest Fantasy, Scenario - Ritual/Spell Requires Xcon, Shapeshifting - Agressor shifts into another form during sex, Watersports - Piss Enema, Watersports - Piss Marking, Xeno - Creature Cock, Xeno - Knotting, Xeno - Tentacles

I got a little carried away with tags here oops. These are straightforward "someone with bad motives gets what they want from somebody who probably deserves better." Aggressor POV would be fun for a lot of these! There's possessiveness, selfishness, manipulation, and just generally bad behavior.

If you're going to use the hilt of a weapon, I feel like the best weapon to use is the victim's own, especially when there are people here who'd have such emotional entanglements with their blades (summer Percy's is a family heirloom! Seofon loves all his swords so much! Albert's sword's radiance "increases the more trust you place in your friendships"!)

I love when Belial has motives beyond just being horny; he's the archangel of cunning, after all. Ulterior motives are his jam. Of course, when you can use somebody for whatever purpose AND get your rocks off, that's the best plan.

Aglovale, under the influence of the Otherworld, remembers that his little brother is so very dear to him, and should be with him always, and now he has the power (and the tentacles?) to make him stay right where he belongs. And love it. Whether he wants to or not.

That, except Yurius with the creepy primal thing he absorbed and Albert at his dear friend's mercy.

Pre-rebellion Belial doing some recruiting with either Azazel or Michael, testing their willingness to follow unusual orders, coaxing them into compromising positions—and it's flattering to be singled out for personal attention by the deputy head researcher, isn't it? Even if these don't seem like normal orders.... (Michael probably keeps her head about her and is less ultimately convinced than Azazel, but please, either way, let them get messy.) ETA have been reminded that Olivia would be a potential candidate here too, if you want more options!

As noted above with monsters, Seofon getting in over his head is hot. Maybe he was pretty sure he could handle Belial in a straight-up fight and was not prepared for the frankly broken success rate of Belial's charm ability, mm?

You know when Ness just casually drugged Gandharva unconscious because letting him start a fight would be tiresome? That same intense disrespect, but with a boner. Ness wants to ride the bull and not put up with Gandharva's everything, and he must have something in his alchemical bag of tricks that'll do the job.

Vira convincing Katalina she needs her help with a rite "to appease Luminiera," only when she has Katalina spread over an altar and is touching her so intimately, there's no sign of a primal beast's presence anywhere...

Granblue Fantasy 4: Gangbangs

Audience Members xcon Aoidos, White dragon knights controlled by Isabella xcon Lancelot, Original Astrals xcon Belial & Lucifer, Mafia Members xcon Nehan, Skydwellers xcon Metera, Cabal xcons Lamorak, Agyo & Ungyo xcon Beatrix
Motive - Bonding Activity for Aggressors, Motive - Fundraising, Motive - Gangbang as Bonding Activity for Aggressors, Motive - Political Motivation, Motive - to Test Loyalty, Penetration - In Every Hole, Comeplay - Covering Victim in Come, Public - Humiliation, Public - Openly Xconned, Public - Public Use, Scenario - Victim used as party favor

That bit in Auld Langxiety where the kleshas got Aoidos and he was urging his entire audience to come get him? Let them.

Or you know some other night when the crowd is too hyped up and just can't be stopped. Maybe some Vicious Three fans start it, wanting to see if "Aoidos" is as tough as the Benjamin they really wanted to see.

Nehan might be working for the mafia, but that doesn't mean he's really one of them. Maybe somebody slips him some of his own drugs, or maybe he's inconveniently going into heat, or maybe the guys are just bored and looking for someone to take it out on. The nerd with the chemistry lab will do just fine.

Did the cabal have a particularly exciting test in mind for the talented young mage who wanted to join their ranks? Or have they called him in after recent events to make him demonstrate anew that he's committed to their cause and will do whatever they require of him?

Lucilius' lab does brilliant work but isn't very popular with the rest of Astral society; perhaps offering up his finest creations as entertainment at the next fundraising gala will help sway public opinion. They'd have to be on their best behavior, outgoing and cooperative, even with Astrals who are quite sure that primal beasts are something less than people.

So in Gripping Freedom when the goon squad have Beatrix tied to the pole with her clothes half undone? They should just summon Agyo and Ungyo and give them boys a treat, is all.

Metera takes so many people for granted, thinks she can get away with so much because she's pretty and clever! And this is basically a break-the-haughty scenario where she gives the wrong people shit at the wrong time and then doesn't have an escape route handy when they want to get some payback for however she was taking advantage.

Shin Megami Tensei: Strange Journey

Asherah xcons Protagonist, Awake Jimenez xcons Neutral Protagonist
Setting - Xcon Carnival/Circus, Victim Performs Oral Sex, Motive - Celebrating Combat Victory Over Victim, Xeno, Magic - Victim Becomes Addicted to Sex with Aggressor, Motive - Aggressor Believes It's Their Right to Xcon Victim, Motive - To Assert Dominance, Body Mods - Marked as Property, Watersports - Piss Enema, Watersports - Piss Marking, Monster - Monster Goes Off Leash, Attitude - Victim Fights Back... Unsuccessfully, Penetration - With the Hilt of a Weapon

So I'm Team Chaos in SJ and when Our Hero (call him Tadano or whatever you want, i'm not fussed about names for this one) doesn't make that call I want it to be a struggle for him. Maybe they're still trying to change his mind but maybe they just want him to be sorry he fucked up.

That carnival tag. The idea of there being a carnal-pleasure carnival as a sector of the Schwartzwelt is completely delightful, hot damn. This is so much my aesthetic. Extrapolate however you like with attractions, rides, terrible carnival games, bizarre settings for Mr. Protagonist to get hunted through/fought in/fucked on.

SMT demon designs are super great and Awake Jimenez is no exception. I love their weirdness and I'd love our boy being uncomfortable with it; give me unsettling texture difference between Jimenez's two halves, or alarming differences of scale between human and Asherah (boss fight size is so good), or any other element that calls to you.

Asherah fucking our boy using the hilt of her obsidian dagger, Jimenez with his standard CQC knife, either one of them making our hero beg for the hilt instead of the blade—I don't want to read about them actually using the blade (well, external scar-him-up-he's-mine would be neat) but making their victim think they might is good shit.

The oral sex tag: absolutely fine with Jimenez (what's the tackle look like now, anyway?) but included because Asherah riding her victim's face A+++.

In my general preferences where I said I usually prefer coercion? This is definitely an exception. Straight-up physical aggression is welcome here.

Shin Megami Tensei IV 1: fucked by demons

Demons xcon Jonathan, Alraune xcons Navarre
Xeno, Religion - Forced to Pray During Xcon, Religion - Penetrated with Crosses/Holy Objects, Religion - Xconned Over Altar, Rituals - Gang Rape for Sex Magic Purposes, Inexperience - Victim Is In Over Their Head, Penetration - In Every Hole, Penetration - Tailfucking, Penetration - Two in One Hole, Penetration - With the Hilt of a Weapon, Anal - Prostate Milking

Somehow there was no tag for the aggressor feeding on the victim's distress but given that demons in IV canonically eat human emotions? That. That's very extremely welcome here.

Speaking of which, lean on the humiliation and embarrassment that go with all that penetration, especially if there's prostate milking involved, and the utter shame of responding to violation by spilling one's seed (all over oneself).

Jonathan would absolutely tell the other Samurai that he'll hold this demon off while they find a way to disrupt its domain—and then one demon becomes a horde, and they're using magic to make him vulnerable...

Navarre was probably going to die if nobody saved him in canon, but please feel free to go hentai bad end with him instead—after having enough of Alraune's tentacles/the hilt of his own sword/other convenient relics stuffed in his holes and being forced to come like that repeatedly, he can't remember what else ever mattered in life.

If Alraune decides to share her new toy with any of her friends, that's good too.

As above, "in every hole" can absolutely include sounding. Yum.

The aggressor in either case could try playing with the religion angle to get more emotional response out of the victim. With Jonathan you could also pin him down in a Tokyo shrine where he can tell this is some kind of religious setting, but the gods (and their demands) are unfamiliar...

SMT IV 2: Yuriko is the pagan sex cult queen of my heart

Yuriko xcons Isabeau, Yuriko xcons Walter
Seduction, Motive - To Turn To Aggressor's Side, Religion - Forced Blasphemy/Sacrilege, Scenario - Forced to Live Out Darkest Fantasy, Victim Performs Oral Sex, Xeno, Religion - Penetrated with Crosses/Holy Objects, Religion - Sacred Ceremony/Ritual Requires Sex (Willing Participants or Not), Religion - Xconned Over Altar, Rituals - Gang Rape for Sex Magic Purposes, Motive - Corruption/Falling From Grace/Giving Into Temptation, Bondage - Predicament Bondage, Motive - To Trigger Dormant Superpower/Magic

Yuriko is here to seduce people to her cause and away from YHVH's, and sometimes that seduction is more literal than others. She wants her victim initiate to understand what a gift she has to offer!

Lean way into the religious bullshit, whether that's perverting YHVH's rituals and symbols or creating/reviving pagan ones, and the psychodrama of making the samurai do this thing that's ~wrong~

Drugs and/or magic to make the victim confused and suggestible or outright welcoming the "knowledge and wisdom" being applied to their flesh: good.

My kingdom for Yuriko topping the shit out of someone without needing to penetrate, using her overwhelmed partner's body to satisfy her hungry cunt.

Maybe induction into the Ring of Gaea involves getting ritually fucked over the altar by existing high-ranking members, with Yuriko presiding and encouraging the initiate to embrace their body's needs and pleasures.

Shin Megami Tensei IV: Apocalypse 1: Possessive demon bastards

Abe xcons Hallelujah, Dagda xcons Nanashi, Krishna xcons Flynn
Death - Resurrection By Xcon, Scenario - Forced to be Team Fuck Toy, Scenario - Aggressor methodically grooms victim over a period of time to accept the xcon, Seduction, Mind Control - Victim Aware of Actions But Unable to Stop Them, Bargaining - Aggressor makes victim choose which hole will get fucked, Penetration - Cock Warming, Motive - To Permanently Claim Victim, Anal - Prostate Milking, Dynamic - Aggressor Is "Nice" As Long As Victim Behaves, Mental - Victim Supernaturally Forced to Share Rapist's Pleasure

Creepy possessiveness with varying levels of sweet on top! Aggressors who don't respect their targets as people with agency but do treasure them for one facet of who/what they are. Some tags more obvious for one ship than for the others but pls mix and match any way you're inspired to.

Coaxing filth, encouraging the victim to make active choices and participate in what's being done to them, so choice. Pet names and assumptions of intimacy, asking where they want the aggressor's come this time...

Krishna so fond of his Kalki, coming back to fuck him repeatedly as the moon grows full, whispering endearments and grand plans for what they'll do together to "save" the world, fingers in his mouth to stop any answers that might not be what Krishna wants to hear.

Hallelujah kneeling at Abe's feet, lips wrapped around Abe's cock, knowing that at the end of this phone call he'll have to decide whether he wants to be choked on it or hauled up and pinned over the desk.

Dagda makes it very clear how much Nanashi belongs to him, fucking him in Yomotsu Hirasaka before returning him to life (whether or not he actually needs to), puppeteering Nanashi's body to make him touch Dagda or himself, purring dirty talk about what a glorious future awaits a puppet who knows his place.

That resurrection tag is most obviously applicable to Dagda/Nanashi but if you want to make it apply to one of the other ships, I'm totally game. JRPG mechanics being what they are, I think you have a lot of wiggle room!

"Setting - Public Bathhouse" wouldn't have made sense for all of them but I sure do like it as a possibility for Abe/Hallelujah, heavy on the decadent yakuza vibes.

I'm really into the possessive "you belong only to me" dynamic you can do with these ships but I also like the idea of "you're mine so I can loan you out," so if you want to involve Ashura-Kai goons (or Samyaza's subordinates), other Divine Powers, or any various deities that Dagda is making deals or "alliances" with, that's great too! On screen, mentions of it happening earlier, aggressor talking about putting the victim in that situation: all good.

SMT IV:A 2: Hurting someone with someone else's dick

Hunters make Their Demons xcon Gaston, Mikado Authorities make Gaston xcon Hallelujah, Samyaza makes Hallelujah xcon Gaston
Scenario - Xcon by proxy, Humiliation - Verbal, Public - Xcon In Front of Audience, Coercion - Victim in desperate situation uses sex as bargaining chip, Motive - To Assert Dominance, Scenario - Xcon as Consequence of Defeat in Combat, Motive - War Trophy/Spoils of War, Religion - Forced to Pray During Xcon, Xeno - Victim is Like Catnip to Non-Human Character

I ship Gaston/Hallelujah and would want any fic involving both of them to acknowledge their growing respect/friendship, whether or not there are romantic feelings—i.e., the one being forced to hurt the other is not happy about it and tries to minimize the hurt if he can.

Early Gaston is so obnoxious, and so clueless about the amount of danger he's in. After he's dismissed his only allies, that's prime time for disgruntled hunters to put this arrogant shit in his place! They'll show him just how "unclean" Tokyo can be.

Forced to pray—either seriously, if this is in Mikado and Gaston is expected to be saving the soul of this filth, or a mocking demand from unbelievers who want to see this crusader not get saved.

Hallelujah fucking Gaston as a way to establish a claim on him so Samyaza('s demons) won't do anything worse; Gaston fucking Hallelujah as a way to "purge the uncleanness" and save him from the stake.

But also, Samyaza making Hallelujah do it to prove he's willing to go that far for his dad/the cause; Mikado making Gaston do it to see if he has the discipline to make it a ritual instead of a sin.

Gaston being coaxed/led into "volunteering" to be fucked, and having to argue for why his ass is valuable enough to bargain with.

Like catnip: a high-strung, repressed virgin being forced to confront sexuality is a recipe for intense emotional turmoil and a delicious meal for any demon close enough to get some of that. Maybe others nearby want to come get a piece of this tasty treat.

Canon divergence in the direction of the game's bad ends makes these scenarios easier to do and is totally fine, but I'd prefer that Gaston and Hallelujah not be without hope of things getting better (I'm absolutely not asking you to have a plan for how things could get better, that would be a big ask).
