General Studies, Class 1-D.
Quirk: Complete Self-Brainwashing.
She completely rewrites only her own brain and perception. No matter what happens in reality, everything is automatically converted into a convenient "internal setting" in her mind.
In objective reality, she is short and so obese that her uniform buttons are about to burst; she is, by any standard, unattractive. However, through her internal brain filter, she is converted into a "slender, lovely, peerless girl idol." Consequently, she frequently winks and strikes idol poses with total confidence while her stomach fat jiggles with every movement.
She genuinely believes she is a "secret weapon with a god-level Quirk meant to save the world, hidden by Principal Nezu as a 'General Studies mob' to keep her from the villains." She truly believes the League of Villains' real goal during the USJ attack and the Forest Training Camp was to capture "her," the ultimate weapon. She desecrates the trauma of Class A in the worst possible way, believing that even the horrific incidents where Mr. Aizawa nearly died and Bakugo was kidnapped happened because "Katsuki-kun and the others acted as decoys so the enemies wouldn't realize I was the target! So touching~♡" She firmly believes she "sent a DM to Shigaraki to hand over Bakugo," something she never actually did. She lies as easily as she breathes for her own convenience and genuinely believes those lies to be facts. Since all counterarguments and evidence from others are shut out by her brain, no matter what anyone says, the conversation remains on a completely different wavelength. However, if her convenient lies are physically blocked or things don't go her way, she immediately flails her limbs like a toddler, screaming at a deafening volume, "Eeeeeek!! Domestic Violence! I'll have you executed!!" while her face gets messy with tears and snot in a hysterical fit.
She routinely bullies others regardless of gender. In her mind, however, this is converted to: "How cheeky of them to get better grades than me, the secret weapon! I'm just educating this ugly person to know their place♡," escalating the bullying with a smile. She genuinely thinks, "I'm U.A.'s secret weapon educating a mob, so there's no need to hide it♡," and bullies people openly in the middle of the crowded cafeteria or right under security cameras with zero stealth and a 100% smug face.
