Yoigoshi Tatsuya was a famous soccer player, but when he entered high school, he took the opportunity to sever every relationship he had with sports. Azemichi Soma barges in on him to invite him to join the kabaddi team, and drags him to practice saying all he needs to do is watch. Yoigoshi thinks it's a ridiculous sport, only good for gags, but he's soon caught in a trap set by the vice-captain, Iura Kei, and forced to try kabaddi for himself...
Was I naïve in thinking a mask would 
be enough to hide my identity?
¿Fui demasiado ingenuo
en solo cubrirme el rostro?
¿He sido demasiado ingenuo
cubriéndome la cara y ya?
Forse non basta una mascherina
a nascondere la mia identità? Sono un ingenuo!
Fui inocente demais ao usar só máscara 
pra esconder minha identidade?
Неужто я по наивности решил,
что маска меня скроет?
