Kira Iwata is one of the Ultimate Jewelers in the class. So, of course, she hates Cassius's guts, claiming him to be a thief (making this worse is that Kira is competitive and wants to win at everything). She might look sweet enough, but Kira hates being called that. The little girl has quite the temper and can use her appearance to get others to do what she wants. Or at least try to manipulate them, Kira is not actually good at that.

She can play the victim, using crocodile tears to get her way...which usually does not work. Kira is immature and acts like a child. Although, if somebody takes the time to get to know Kira, she can be a nice girl.

Kira has a mysterious connection to Hope's Peak Academy and its new headmaster, Ayano Kirigiri.
