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...
But in reality, is he the toughest to handle?
لكن في الواقع، هل هو الأصعب من ناحية التّعامل معه؟
Ist der etwa insgeheim der Schwierigste?
¿No será el más difícil?
¿Y no será el más difícil?
Ma in realtà è il più difficile da gestire?
É o mais difícil deles de 
se lidar, na verdade?!
Но на самом деле с ним сложнее всего?
