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 say
you can't leave the castle?
ألم أقل أنّكم لا تستطيعون الهروب من القلعة؟
Ya dije que no pueden salir del castillo.
Mira que os había dicho
que no podíais salir del castillo.
Io glielo avevo detto, 
che da qui non si può uscire...
Não falamos que não dá para sair?
Потому-то я и сказал,
что из замка вам не сбежать.
