A classmate of Ichigo Kurosaki and Orihime Inoue. She has short brown hairs. She's very shy, and is afraid of Ichigo and Uryū Ishida because they never smile, though she did bring Uryu one of her torn dolls so he could fix it during one moment. Like Orihime, Michiru is also a victim of Chizuru Honshō's advances.

She's found asleep along with Chizuru during the "Fake Karakura Town" arc, but unlike Chizuru, she never wakes up during the entire crisis.
