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.
Is it true that if
you're splashed with water,
،هل صحيحٌ أنّه إن تبلّلت بالماء
Stimmt es, dass das Jutsu des Himmels-
gefängnisses bei Wasserkontakt verschwindet?
È vero che se ci si spruzza sopra dell'acqua, 
la Prigione Celeste viene annullata?
É verdade que se você
for tocado pela água,
А правда, что вода аннулирует
эффект «Небесной тюрьмы»?
