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.
Didn't I tell you to treat prisoners
with respect?!
!ألم أخبركم أن تعاملوا السجناء باحترام؟
Ich sagte doch, dass ihr die Insassen
mit etwas mehr Respekt behandeln sollt!
¡Les tengo dicho
que traten con respeto a los presos!
¡Ya os tengo dicho
que tratéis con respeto a los presos!
Vi dico sempre di trattare i detenuti 
con rispetto, volete capirlo?!
Eu não lhe falei para tratar
prisioneiros com respeito?
Разве я не говорил быть
с заключёнными вежливее?!
