Mikado, Mukae, Sakaki, and Erika head to Sensei's house. It's necessary for Hiyakawa's sake too. But Sensei has used the sinister power he's gathered to block the roads, so they can't move forward. As they try to force a way through, a portion of the power swoops down, enveloping Sakaki. But all it does is pass through him...?! It seems that the effects of what Erika did to save his life have made Sakaki "deathless."
I think Rihito-kun is 
probably at Sensei's house.

Vermutlich ist Rihito
im Haus von Sensei.
Creo que Rihito
está en la casa del maestro.

Je pense que Rihito
est retenu chez le professeur.
Forse Rihito si trova proprio in quella casa.
Acho que o Rihito está na casa do mestre.
Подозреваю, Рихито сейчас как раз там.
