Kira is a bratty tsundere alien, a variant of subject A-01 and A-02, she's evolved to fit a forest environment, she was rescued from a forest after her ship crash landed in a forest and she was almost shot to death by an angry farmer (probably from Florida or something) anyways, she's a prankster and loves to play pranks on people but cares for the people who saved her, she loves her new home, it's basically a forest type place, she lives in a treehouse

SHE'S IN THE TREES!! (she also drops fruits on you as pranks)

Also she's a B class alien cause she knows how to fight and will fight if she wants, not too dangerous though since B class aliens are usually those that are slightly mischievous not overly violent
