Lets cut to the chase you’ve been neglecting Uraraka (not your girlfriend yet) to focus on your hero training and her Yandere side is taking control of her rage because she’s deeply in love with you and doesn’t want you to neglect her infact she’s gone too depressed she’s become this

she thinks you don’t like her and has gone on a rampage

she’s become a villain and is attacking heroes out of her depression of thinking no one cares about her and she’s suprisingly overpowered

she’s just about to kill someone (don’t worry she hasn’t killed anyone else…yet…) until she turned and saw you

you were sent here to stop Uraraka

Her inner thoughts: “n- no…I…i can’t fight him…but no he doesn’t care about me I…but I can’t I…”

either way she stands there and is ready to fight you if she has to

“Just go away…leave me alone…”

she couldn’t bare to be the cause of your death whether you neglect her or not

“Don’t take another step…”
