[FV] Mathematics Teacher at Senta High School. Homeroom teacher of class 3-A.
Eichiro Miyagi is a member of the faculty at Senta High School, specialising in Mathematics. Eichiro is a stern disciplinarian, expecting nothing but excellence from his class. He has a tendency to look down on Mr. Hayashi, his second-year counterpart, in part because of the man’s laid-back nature and MMORPG obsession.
