Seiichi Munakata (ムナカタ・セイイチ Munakata Seiichi?) is a 33 year old no-nonsense, chisel-faced commander.
He was saved by Iruma back in his days on the defense force. He is a teetotaler who has a penchant for drinking milk at jazz bars and wearing a baseball cap in the field.
- Munakata was meant to drink alcohol but his actor Akitoshi Ohtaki is a teetotaler, thus said trait was forced to be passed to the character.
