Okazaki’s pick-me behavior stems from a toxic mix of intense shyness, deep quirk insecurity, and projection.

Because she genuinely hates her own highly coveted Teleport quirk, she seeks validation by tearing down classmates who are proud of theirs—hiding her jealousy behind a shy, victim-like exterior.

Due to this fact most people whom are proud of their quirks avoid her and even question why become a hero student in the first place. The reason she is a hero in training is due to one thing: make everyone as miserable as her so if ever she finally finds peace with her quirk she can simply put them down more for having the mentality of hating their quirks.
