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...
It's Mister Number 15 to you!
!عليك مناداتي بالسّيّد رقم 15
Nun red nicht so von oben herab!
¡Llámame señor número 15!
¡A mí me llamas señor número 15!
Qui t’a permis
de nous appeler comme ça ?
Devi essere più formale con noi!
É Sr. nº 15 pra você!
А чего так неуважительно обращаешься?
