Nu: Carnival character writing is wild
Eiden: Oh it's a boring MC with no personality ->->-> actually he has a HUGE personality and is super charismatic. but he also grew up with neglect and no permanent connections. one time he tried to reestablish a friendship and it was all a pretense to manipulate and violate him. he is a fundamentally lonely person who wants to have some stability but does not believe that he's worthy of it. also he fucks himself multiple times
Aster and Morvay: oh it's a bottom bitch femboy vamp and a succubus ->->-> they both struggle with their creator/master disappearing for long periods of time, even decades. blaming him would be too painful so they wonder if something about themselves is fundamentally flawed. also the "bottom bitch" is a stone top with a huge strap
Yakumo: it's a yandere-ish quiet guy ->->-> actually he's very good friends with his metamors and is just insecure about his own place. he was born into one culture but adopted into another, and was fully accepted in neither. his adoptive grandparents are great, and he has connections in his village, but he feels as though he is one mistake away from losing it all, including eiden. even if he doesn't hurt eiden, he worries that he will outlive him. also his schlong is long
Edmond: it's the tsundere ->->-> a devoted knight who struggles with keeping his morals while adhering to his king's orders. grieving a loss that profoundly affected him, worrying that it will happen to the person he now loves. also he likes sweet food a lot
Olivine: oh it's the priest who will be corrupted ->->-> okay actually he's already "corrupted" in the sense that he is massively horny but has been shamed all his life to believe that wanting anything is corrupt, even the basic joys of childhood. He is so used to emotional abuse and punishment from his parents that when he "sinned" by being a normal teenager with hormones he dished punishment on himself via self harm. despite it all, even with priesthood being a shackle on him, he loves his religion and he loves helping people through being a priest. also he has huge boobs, I mean some serious honkers. A real set of badonkers. Packin' some dobonhonkeros.
Quincy: sleepy guy ->->-> isolated man who was rejected from the very tribe he swore to protect. scared of getting attached, as he is used to loss and expects his love one to die. also his dick is huge.
Kuya: kind of abusive/problematic love interest ->->-> more of a prankster than anything that deep (but he likes to pretend he's more dangerous than he is). bitter about his companion (love interest?) disappearing and eiden reappearing in his place, but learning to love again. chronically suicidal due to the sheer boredom of being hundreds of years old. also he knotted eiden once
Garu and Karu: oh no, DID, I'm sure this won't go well ->->-> unironically probably the best DID rep i've ever seen??? fantastic depiction that finds a sweet spot between "these are two different people" but also "they share a brain and body so there will be crossover." Karu isn't remotely a Bad Alter (though he'd like you to think so, at least at first). Everyone collectively views them as separate identities. also they play rock paper scissors to determine who should front.
Blade: Oh it's Clear DMMD ->->-> yeah kinda Clear DMMD, but has intrinsic ties to overall lore and a very open gender presentation and struggles with social cues that in ways that can be very relatable to neurodivergent people. also he loves dresses
Dante: Cranky guy with orientalism issues ->->-> okay to be fair the orientalism is there, but his crankiness comes from a deep place of hurt due to losing his parents. he knows that kindness can lead to violence so he tries to push down his feelings as much as possible. also he's a cat dad
Rei: Oh it's Kaname Date- I mean, it's an aloof dom uke ->->-> good lord where to fucking start. His apparent "masochism" is just a horrible coping mechanism for past sexual trauma. And although he's not upfront with this, Eiden is emotionally intuitive and knows how to be gentle with him. He also has bullying trauma. And parental death trauma. Also he's chronically ill and has seizures. And is partially a bird? Maybe??? But he gradually heals over time and learns to accept love. Also he canonically smokes weed (catnip)
