Aki gets stabbed by Kobeni while protecting Denji. Seeing this, Denji jumps inside the “Eternity Devil” and starts attacking it. He fails to kill the “Eternity Devil” and his chainsaw power ends up fading after losing too much blood. But then, he manages to restore his power after eating the devil’s flesh and drinking its blood, and begins to fight back.

As Himeno watches Denji, she remembers the saying, “The Devil Hunters that devils fear are the ones with a few screws loose...”

Denji and Power complete their training with Kishibe, while Aki Hayakawa makes a new contract with the "Future Devil" through Kurose and Tendo.

Meanwhile, Makima threatens the yakuza boss into revealing the names of all those who have made contracts with the "Gun Devil," along with the location of Samurai Sword's hideout.

The time has finally come for Public Safety to begin their counterattack against Samurai Sword and his companions.
