Age: 16

Birthday: February 5

The only first-year student of Saint Ishiyama to become a member of the Six Knights. He is the captain of the Karate team and a master of Hakkyokuken, as well as an advanced practitioner of the fictional Izuma-style martial arts. Miki knows Oga from middle school, where Oga (intentionally or not) saved Miki from a group of high school delinquents. Wanting to become stronger, he started to hang around Oga, but later realized that this would not make him any stronger, because no matter what kind of fight he was dragged into, Oga Tatsumi took care of everything. However, when they meet again at St. Ishiyama, he appears to hold deep feelings of contempt towards Oga and to be obsessed with proving to his former classmate how strong he has become.
