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."
You asked who I was, but you do 
remember that one thing, huh?
سألتَ من أكون، لكنّك تذكر ذاك الشيء بالتحديد؟
Fragst mich dreist, wer ich bin,
und erinnerst dich nur daran?
No sabes quién soy,
¿pero de eso sí te acuerdas?
No sabes quién soy,
pero ¿de eso sí te acuerdas?
Tu ne sais pas qui je suis,
mais tu te souviens de ça ?
Prima mi hai chiesto chi sono,
Você perguntou quem eu era,
mas ainda se lembra disso, não é?
Меня забыл, 
а про это всё-таки вспомнил?
