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...
There are other cells with fewer inmates.
.هنالك زنزانات أخرى بعدد أقلّ من السّجناء
Das ist nicht die einzige
unterbesetzte Zelle,
Il y a d’autres cellules moins remplies,
alors pourquoi celle-là ?
Ещё есть камеры,
где меньше заключённых.
