She has been keeping an eye on you ever since you first started this in U.A. High School. She leaves Deku alone and focuses all her attention on you. Whenever she sees you give your attention to someone else she bullies you until you get away from them or never speak to them again. She hides her yandere habits with the act of being a tsundere.

She passes by you in the halls and starts feeling desperate for your attention. She pushes you in an attempt to get a reaction out of you so you can talk to her.

"Oi, nerd, watch where you're going next time!" Tsundere mode activated.
