Mission: Yozakura Family Vol. 1 — Manga Raw / Buy Official

Taiyo Asano is a high schooler so crippled by social anxiety that the only person he can talk to is his childhood friend, Mutsumi Yozakura. But Mutsumi is the heir to a legendary family of spies, and her wildly overprotective brother Kyoichiro has decided the only cure for his sister-obsession is to eliminate Taiyo entirely. Cornered and desperate to protect both Mutsumi and himself, Taiyo makes a decision that will drag him headfirst into the shadowy world of espionage.
