Despite his intimidating appearance and the prominent scar on his face, Tatsu proudly serves as a full-time househusband after leaving his yakuza past behind. He dons a teddy bear-adorned apron and eagerly participates in challenges like flower arranging and housekeeping to gain acceptance from a women's organization. Drawing on his previous experiences including grocery shopping and other domestic tasks, he approaches homemaking with the same level of dedication as his former occupation. Tatsu's tranquil routine is frequently interrupted by haiku battles, typhoon alerts, and cosplaying villains. However, for the sake of his beloved wife, Miku, he embraces every challenge that comes his way. Even when old acquaintances from his yakuza days reappear, Tatsu remains committed to his new role. Regardless of the chaos that comes with homemaking, Tatsu never wavers in his determination to succeed.
