ONA
Description
Masa is a supporting character in the anime The Way of the Househusband. He was a member of Tatsu's former yakuza gang, serving as one of his underlings during Tatsu's days as the feared Immortal Dragon. After Tatsu retired from the criminal world to become a full-time househusband, Masa and the rest of the gang struggled to maintain their operations, particularly in dealing with the rival Kunimi Clan.

Masa's background as a yakuza shapes his personality. He is deeply loyal to Tatsu and initially struggles to accept Tatsu's new domestic life. He often visits Tatsu in the hope of convincing him to return to the gang. However, through chance encounters where Tatsu drags him along on daily chores, Masa gradually comes to realize that Tatsu's new path is pursued with the same intensity and discipline as his old criminal life. This realization marks a turning point in his character development.

His primary motivation is his unwavering loyalty to Tatsu. He admires Tatsu's strength and dedication, and he initially feels lost without the structure of the gang. Over the course of the series, Masa evolves from a directionless former hoodlum into a junior apprentice of sorts, attempting to emulate Tatsu's domestic skills. He learns that the way of the househusband requires the same commitment and rigour as the yakuza code.

In the story, Masa serves as a recurring foil who highlights the contrast between Tatsu's past and present. His interactions often lead to comedic situations as he tries to reconcile his old worldview with Tatsu's new priorities. Masa's key relationship is with Tatsu, whom he respects and follows. He also maintains ties with other former gang members but is most frequently seen alongside Tatsu.

Notable abilities include his familiarity with yakuza customs and his willingness to learn household chores under Tatsu's guidance. He has no exceptional physical or combat skills that set him apart, but his dedication to adapting to a civilian lifestyle becomes a defining trait. Over time, Masa develops a genuine appreciation for the domestic discipline Tatsu embodies, moving from confusion to acceptance and even emulation.
