#rin & serena hate each other serena being jealous of rin and when serena leaves and ruri follows rin hates her for taking ruri from her

[angeat]

I don't know if it'd be up your alley but for the yugioh lesbians prompt, Ruri/Serena with optional 闇落ち/Academia Ruri because that shit makes the hamster in my brain go circles

thank you for this my brain completely and utterly ran away with it and went like full au mode so. cough

my interpretation of this is when ruri is kidnapped she is brainwashed into being an academia solider, forgetting her previous life though naturally she's not allowed out like serena so she gets very attached to her.

ruri doesn't mind it nearly as much, she has more faith in what leo says and lacks the level of pride in duelling that makes her want to show off so she simply finds most her enjoyment in being alone with serena.

serena has no idea how to really handle ruri's company or how to feel about it because she's never had someone with an unabashed genuine interest in her and being a friend to her rather than like... a bodyguard or something so she has a tendency to push ruri away, but ruri is perceptive enough to tell she sort of likes the attention, she feels hurt sometimes but it just motivates her to try to be closer and understand serena better.

ruri being as social as she is, when the others like sora and dennis are present she tags along with them as much as she's able so she gets like stories of what they did while deployed out and such.

given the way her morals are kind of absent since her brain is 100% academia propaganda with the brainwashing, evidently she absorbs a little of a sadistic streak from them so she's a bit Weird. being like innately a gentle polite sweetheart but also "omg I hoped you made him beg and grovel to be spared and watched all hope drain from his eyes as he realized you wouldn’t"

once plot happens and serena goes off on her own and defects, still at academia, ruri (after being in shambles from the news for a while) is like "I have to kill this motherfucker" and so escapes solo JUST to hunt serena down. turns into a toxic yandere yuri thing. because of course it does. I could go on.
