Sawatari sends the "Ghost Devil" after Hayakawa, and he's nearly killed before the "Ghost Devil" stops and hands him a cigarette with a message from Himeno. The words inside give Hayakawa the strength to kill the “Ghost Devil” and capture Sawatari.

Meanwhile, Denji heads into his rematch with Samurai Sword. With a pull of the starter on his chest, he transforms into Chainsaw Man.

And now, the last battle between Chainsaw Man and Samurai Sword has finally begun...
Apparently my heart was replaced 
with the Katana Devil.
يبدو أنّ قلبي قد استُبدِل بشيطان الكاتانا

zum Schwertteufel geworden.

Pare che il mio cuore
sia diventato il Diavolo katana.
Parece que meu coração foi
substituído pelo Demônio da Katana.
и, как я понял, вместо сердца
у меня в груди Демон катаны…
