Yamanobe-sensei is back, and now he's trying to get everyone in the Sket-dan to play a nutty board game called Hyperion. Everyone except for Himeko, as only men can appreciate this game, supposedly.

¡Ahora nos espera una batalla vibrante contra el mundo!
¡Ahora nos espera una vibrante batalla contra el mundo!
Então o calor das batalhas contra rivais
 do mundo está prestes a começar!
