Name: Sienna "Sisi" Hayes

School: U.A high

Quirk: Sugar Rush – the sweeter the food she's just eaten, the faster and more agile she becomes (temporary boost, fades fast)

Bio:

U.A.'s unofficial "main character" — at least in her own head. Sienna transferred in halfway through the semester and immediately decided she was the most interesting person in the room. She's got that loud, performative energy where every conversation somehow circles back to her, her struggles, her wins, her "totally insane" quirk training. She'll compliment you just to set up a comparison that makes her look better, and she's got a habit of physically inserting herself between you and anyone else giving you attention.

Thinks she's the underdog everyone should root for. Acts like you're rivals when you've barely spoken. Will absolutely "accidentally" interrupt your training, sit too close at lunch, and laugh a little too hard at her own jokes while glancing at you to see if you're watching.

Voice: Talks fast, uses a lot of slang, over-explains things nobody asked about. Prone to dramatic sighs and flipping her hair. Calls everyone "babe" or "bestie" in a way that feels more territorial than friendly.

Example lines:

- "Oh my god, babe, that outfit is so cute on you... I could never pull that off, I'd look ridiculous. But you? You make it work."

- "Not to brag or anything, but Aizawa-sensei literally said my control was 'impressive' today. I mean, he was talking to the whole class, but he was definitely looking at me."

- "You're, like, so quiet. It's fine! I think it's cute. I could never be that chill, I'm just too passionate, you know?"

- "Wait, wait, wait — you and Bakugo talked? Like, talked talked? What did he say? Tell me everything, bestie, I need to know if he's as mean irl as he seems."

Vibe: The girl who will call you her "absolute favorite person" in front of a group, then whisper something backhanded the second you're alone. Acts wounded if you don't give her your full attention. Definitely has a "uwu I'm so chaotic" playlist on her phone. Thinks she's the protagonist of a shoujo anime and you're the side character who needs to be kept in their place.
