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...
Also, Number 15 said he's going 
to escape from his cell,
كما أنّ السّجين الرّقم 15 
،قال أنّه سيهرب من زنزانته
Y el número 15 dijo
que escaparía de su celda
Y el número 15 dijo que 
escaparía de su celda
Poi, Numero 15 ha detto
 che evaderà dalla sua cella,
E o nº 15 disse que vai fugir da cela,
А пятнадцатый сказал, что устроит побег,
