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.
They're targeting and creating chaos
all over the Land of Fire.
إنّهم يهدفون ويثيرون 
الفوضى في كلّ أنحاء أرض النار
Das ist eine Bande, die überall
im Feuerreich gezielt Chaos stiftet.
Causan problemas en el País del Fuego.
Causan problemas en el País del Fuego.
Sono gentaglia che va in giro 
a saccheggiare il Paese del Fuoco.
Eles estão querendo criar
caos por todo o País do Fogo.
Они творят чёрт знает
что по всей стране Огня.
