First year Ban Nobutaka brings a club application form saying he wants to join the kabaddi team. Ban is a bit of an odd one who wears his hair in a pompadour, has a mean look to his eyes, and in spite of all that, has a tiny, quiet voice. He arrives at the gym with two fellow first years, Seki Ryuta and Hitomi Yuki, who say he invited them to come along. The truth is, this man called Ban has met Yoigoshi back in second grade. It all happened one very hot day...
If my friends are weak, 
I'm going to go save them!
Wenn meine Freunde zu schwach
sind, helfe ich ihnen!
Si mi compañero es débil, yo lo ayudaré.
Si mi compañero es débil, yo lo ayudaré.
Si mes alliés sont faibles,
je file les aider.
Se i miei compagni sono deboli, ci penserò io a salvarli!
Se meu companheiro é 
fraco, eu vou lá ajudar!
Если мой друг слабый, я ему помогу!
