Mission: Yozakura Family

夜桜さんちの大作戦

Taiyo Asano is a timid high-schooler whose only source of courage is his childhood friend Mutsumi Yozakura — until he learns she is the head of a multigenerational spy family hunted by enemies at every turn. To survive the lethal attention of Mutsumi's overprotective older brother Kyoichiro, Taiyo enters a hasty marriage with her, binding himself to the Yozakura clan. Now embedded in a household of elite covert operatives, he must train from scratch to protect the person who has always protected him.
