Boku wa, Kishi Gakuin no Monica.

When a knight died fighting, he was reincarnated into the body of a girl named Monica. He took over her name and body, and now he is going to live in a school dormitory surrounded by girls as "Monica"! In order to fulfill Monica's final wish, he will show the school what a proper knight should be like!
