One of the rabbits Haru was taking care of.
Following the rooftop incident, she ended up possessing Mikami and becoming her body's dominant split personality - an extremely carefree, friendly and upbeat girl that always speaks her mind. She enjoys showering Haru with over-the-top displays of affection. Due to being a rabbit, she doesn't understand a fair amount of things humans do, resulting in a wide plethora of lewd, awkward and humorous situations.
She's capable of manipulating others' memories via signals she sends from her ears, allowing her to blend seamlessly into the school's environment and live with Haru's family by convincing everybody around her that she's always been there.
