He loves heroes and wishes to become one someday... Gravi member Arata Uzuki and his childhood friend Aoi Satsuki are to appear on a show on which participants play the game tag. When Arata learns the prize is an appearance on the hero squad show "50 Ninjas," he becomes uncharacteristically pumped up. While passionately describing his feelings about heroes, Arata recalls an event from his childhood that he had nearly forgotten.
With coordinated teamwork, the childhood friend team... aims to win!
If you don't let me beat you, 
the fight won't end.
إن لم تدعني أهزمك، فلن تنتهي المعركة
Si no pierdes, no acabará el juego.
Si no pierdes, no acabará el juego.
C’est sans fin, si je gagne pas.
Se non ti lasci sconfiggere,
il combattimento non finirà.
Se você não me deixar vencer,
a luta não vai acabar.
Если ты мне не проиграешь,
бой не кончится.
