Masanosuke Ooki

Age: 33
Birthplace: Kouga

A loud and boisterous former Ninjutsu Academy teacher, he's currently a leek and onion farmer living in Kuise village. He and Nomura have been rivals since his teaching days, and the rivalry hasn't calmed down since Ooki left. Even the reason for Ooki's current choice of career is that Nomura's hate for leeks and onions is his biggest weakness.
