Koryuji Holdings is her family's company. A high school student and cheerleader. The Koryuji line have been monks since feudal times, and have been active behind the scene throughout history. Mii has a cheerful personality, but is also a little short-tempered and can be selfish. Although she would never admit it, she also a has a bit of a crush on her tutor, Kogoro. She has been trained in the monastic martial arts since she was small, wielding a transformable long barreled gun called the "Dragon Jewel," the multi-shot "Purple Pot" and four shotguns built into the heels of her shoes called "Tiger Heels". Her vocabulary can at times be a little dated.
