Masa

Japanese name:

政

Masa is a member of the Seto Group and the kendo teacher of San. He has an afro and always wearing sunglasses. Masa is the one who, through performing CPR, "stole" Nagasumi's first kiss. He also transfers to Nagasumi's school, becoming his math teacher (whose word problems tend to describe to the mathematical aspects of underworld gang operations). There is a running gag of Nagasumi displaying an attraction towards Masa since their 'first kiss' in the first episode.

Masa is the only one in the Seto clan apart from Sun's mother who doesn't object to the engagement and sometimes even gives advice to Nagasumi. Usually he is portrayed a silent man. However, when he drinks he tends to talk too much and reminisce. Spoiler!He is revealed later in the series to be the long-lost brother of Akeno Shiranui. Masa cares a lot for his sister Akeno Shiranui and is very protective of her often beating up those who are aggressive towards her. Masa is one of the few Merfolk not afraid of cats; he says that he decided to overcome the fear as a child.
