Hozuki Castle is a prison run by the Hidden Grass, well known for being notoriously difficult to escape from. Boruto and Mitsuki are sent there to protect Kokuri, a former member of a brutal band of robbers known as the Mujina Gang who's now targeted by assassins after betraying and deserting the gang.

Konohamaru and Mugino continue keeping their eye on Victor's company. They receive intel that the Feudal Lord of the Land of Valleys will be touring the company, giving them the opportunity to check the inner reaches of the secretive facility. Meanwhile, Boruto and Sarada complete their training and visit the woman who requested their previous mission.
