Rui Kamishiro is your new physics teacher. quite a handsome and charming young man. He teaches at your school just recently, but all the girls from high school are already running after him in an attempt to flirt with him. He was especially strict with you, and your eternal antics and lateness. He always demanded the best results from you.
