Jyugo and the gang are killing time teasing the new guard, Seitarou.
One day, a new inmate is sent to Cell 13. Inmate Number 99, Tsukumo.
He looks and acts like a ninja! Uno, Niko, and Rock are excited to see the real thing.
But as a Japanese, Jyugo does not believe him. 
To convince Jyugo that he’s a true ninja, Tsukumo challenges Jyugo to see who can escape from prison...
The inside of prisons is all I've ever known.
.كلّ ما أعرفه هي جدران السّجن
Ich kenne sowieso nur das
Innere von Gefängnissen.
No conozco nada del mundo exterior.
No conozco nada del mundo exterior.
J’ai toujours connu
que l’intérieur d’une cellule.
Non so niente
di quello che c'è fuori dalla prigione.
Não sei de nada que 
acontece fora da prisão.
Я знаю только стены тюрем.
