The Class A Finals pit Arata vs Shinobu, Class B is between Taichi and Rion in the same area where Komano is participating in the Class C Final. Chihaya is stuck between supporting Taichi and Komano or experiencing the match between Arata and Shinobu.
Maybe she's not coming because 
she's watching Wataya-san's match.
Quizás no viene por ver 
el encuentro de Wataya-san.
Quizás no venga para ver 
el encuentro de Wataya-san.
Talvez não venha por causa 
da partida de Wataya.
