Mission: Yozakura Family

"Under Mutsumi's orders, Kyoichiro and Taiyo pursue the fleeing Momo. Taiyo manages to land a punch on Momo once, but the gap in abilities between himself and Momo, who can hold his own against Kyoichiro, is all too clear, and he's left on the defensive. On top of that, numerous Dark Cherries - creatures birthed by Tsubomi, which feed on humans as nutrients - appear, blocking the way.

The kids come running when they see Ryu, and soon they're having a lively conversation, but... ?!"

Futaba and Shinzo have vanished from the Yozakuras' sight. To get their abducted siblings back, Mutsumi and the others regroup, but Futaba and Shinzo's inexplicable actions have left them visibly upset. Then one day, Shion sends Taiyo on an errand to the Gaon Mall with Kengo. But Taiyo and Kengo soon find themselves surrounded by spies whose simmering resentment towards the Yozakura family is nearing the boiling point, thanks to Momo! They're on the brink of a brawl when a woman shows up. One word from her, and the fight is stopped…
