The third seal has been killed, but not by the humans, but by the nine demons. The seal is the gateway to the afterlife, and the seal that opens it is the third seal that judges the lives of those who have died. The ninth demon attacks the seal, but the seal can't deal with it. The nine demons attack the seal again, but this time the seal is gone. The mask of the seal has fallen off, and it's clear that the ninth demon is eating the anti-magic particles. The anti- magic particles destroy the ethernanos in the skin. The only thing that matters is protecting the girl he loves, and that's all he cares about.
