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."
If it turns out that you can't die, 
no matter what you do...
...إذا تبيّن أنّك لا تموت، مهما فعلت
Falls du überhaupt nicht mehr
sterben kannst,
Si de verdad ya no puedes
morir pase lo que pase,
Si de verdad ya no puedes
morir pase lo que pase,
Se por acaso você não morrer de jeito nenhum,
