Seiji is the pompous piano prodigy of Habataki High School. He has wavy blue hair and red eyes. He comes from an upper-class family so he is used to escorting someone in an elegant way. Despite his slightly crabby personality, he has a large fan base in and outside school. He actually is quite open minded to new things even when he denies it. He likes piano or anything art related. He dislikes sport or anything that requires him to move a lot. He is also afraid of dandelions. He is a tsundere.
