Mikoshi Kyuri (probably Japanese name order) is one of the team of students the Yama Dojo sent to count coup on Whateley Academy by stealing something that was supposed to be protected. Mikoshi appears to be an avatar, with the spirit of the tiger. He's definitely cruel, torturing and killing small animals for no reason other than that he can. He's good with a sword, which is empowered by his spirit. In keeping with the theme naming of the team kyūri means cucumber.
