We got saiki reader, how about kaido wb reader? I think they lowkey got matchy personality cuz of how weird they are. Kaido!reader who's convinced that a evil organization is controlling the world and it's out to get them and they're the only one who could stop it with their "hidden power" which what causes reader to be an outcast within the batfamily ofc
Based on this one saiki k post
KAIDO!READER: You may have been neglected for a strong portion of your life, all these fantasy ideas just to make your life a little bit more interesting. You may not be a vigilante, a dark stalker of the night, but you can just dream it, and it's just as good as the real thing. You may not be as special as the Robins, have keen fighting skills, and amazing senses, or be raised by assassins. Drink, interesting person. Overall, even awkward moments, it was great to talk to. Someday you'll finally grow up and stop blaming Dark Reunion for all your troubles, but until then, you'll be the little weirdo that everyone loves, even if that love isn't from the person you want to be.
KAIDO!READER! Who blames literally everything on dark reunion? Stub your toe? Dark reunion. Fail the math test? Dark reunion. Your adoptive family ignoring you? Ignoring you? Yeah, definitely dark reunion. They're trying to kick you down, hurt you, see you down in the mud, but that won't ever happen. You're strong, you're resilient, and with the power you possess in this red bandage, dark reunion will never get a one up on you.
KAIDO!READER: You have a little cassette tape that plays your theme song when you appear in classes, when you show up for hangouts with your friends, and when you're doing almost anything. Really, the cassette tape always plays, making your entrance known and you do a silly little pose to show how important you are. I mean, in a crowd of people, some would say you are the enemy stand user. Just look at you, you have your own theme song for when you enter an ice cream shop while you pose, asking for cookies and cream.
KAIDO!Reader: You like to claim that you're stronger than ten men, but you have the power of a wildebeest in the claws of a mountain tiger when, really, you're built like a stick and have the muscle mass of a four-year-old. When playing sports, you are the one who is last picked just because, well, you suck at them. Literally, a dodgeball that wasn't even thrown that hard knocked you out for half an hour. If one is a little too strong, one day you'll fly away into the distant sunset with your theme song playing.
KAIDO! READER: What time did you get yourself out of a love confession by lying, saying, "So sorry, this evil power that dwells inside of me will never let us become lovers, and with dark reunion after me, how will I know I can keep you safe? Sorry, we can't be together," you say solemnly, walking down a hill, but you end up tripping, rolling down, your cassette tape playing your theme song as you roll. So much for trying to look cool.
