Masa has wild, light hair that stands up. He's always covered in bandages from getting roughed up. His ears are pierced, with a chain at his neck, his shirt open to expose a white undershirt. Mesa is quite lazy and his house messy, having a habit of getting into trouble. We do not know any relatives. His occupation is a Yakuza Member while his age is 20-21 (early 20's.) He has a fear of the dentist and is also broke much to his dismay. He often sleeps through the days unlike Tatsu.
