Mimika

Once a rabbit, she merged with Mikami and became the dominant personality. She is incredibly outgoing and carefree. She is also in love with Haru, and showers him with affection whenever possible, sometimes going beyond the bounds of common decency. Her ears are capable of sending out signals that tell most people she is human and that her presence is normal, allowing her to integrate herself into Haru's school with her classmates believing that she has always been there.

Though she has inherited Mikami's looks, she is easily distinguishable from Mikami as she has blonde hair, buckteeth and an even larger bust. She also wears white gloves, in contrast to Mikami's black gloves.
