Amasaka Miko

She felt dangerous because of her brother's remark "I want to be a girl's pants" and moved to the girls' dormitory.
She doesn't know if she knows her mind, she becomes a classmate of the school where the main character moved in. Apparently she wasn't told by her parents about her brother's transfer.

She is a preeminent class representative and she attends as a popular honor student with a warrior, but she has a slight delusional habit.
She is therefore she, she sometimes goes to the world of delusions.
After school, she works part-time in the maid costume diner "Grand Southern Cross".
She is a great friend of Kagura.

"Why is my stupid brother in such a place !?"
