Mikatan Narugino

Mikatan is very positive and happy, as well as caring for her friends. She lives in room 101 and is a member of the idol group "She's Mei." In her free time, she also is a masked hero of justice named "Strange Juice" who uses super strength and a giant straw to fight evil.
As a child she grew up in a research lab under the name Chiyoko, but in an accident her soul ended up in the body of her friend Guriko.
She is currently, in the history where humanity lives on, in her original body (the body Yuuta was using) with black hair.
