Mission: Yozakura Family

High schooler Taiyo Asano has been antisocial since losing his family in an accident. One day, the vice principal shows him something disturbing.

The morning after becoming Mutsumi's husband, Taiyo awakes to find Kyoichiro, who whisks him away and explains the Yozakura family's duty.

Taiyo asks Futaba to train him, but she says he must first live at the Yozakura house for a month. Mutsumi grows worried as she watches him struggle.

When Mutsumi asks Kengo to resubmit some paperwork, he flees and hides somewhere in the mansion. She and Taiyo scour the premises in search of him.

Suspecting Taiyo of belonging to a secret organization, a detective brings him to a police station and pressures him to reveal his accomplices.

After the Yozakura family database is hacked and Taiyo’s data is stolen, he encounters Ayaka Kirisaki, a spy who is dangerously obsessed with him.

Taiyo heads to a lab to extract an undercover Nanao but soon encounters two operatives from a government intelligence agency called Hinagiku.

Sui brings Mutsumi and Taiyo to Hinagiku's headquarters, where they meet its director Rin Fudo — but Kyoichiro suddenly bursts in and attacks Rin.

After Kuroyuri escapes, Taiyo learns his true identity. Kuroyuri then begins a livestream with the kidnapped deputy prime minister seated beside him.

Rin throws a hot pot party to celebrate completing the mission. Taiyo tells Mutsumi he's too afraid to open the box he received from Kurogao.
