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...
And why exactly was Sawatari 
after the Chainsaw Devil's heart?
وما سبب استهداف ساواتاري قلب شيطان المنشار بالضبط؟
Aha.
¿Y Sawatari para qué quería el corazón
del Demonio de las Motosierras?
¿Y por qué querría el corazón
del Demonio Motosierra?
Mais encore ?
E quindi
E por que exatamente a Sawatari queria
o coração do Demônio da Motosserra?
Хорошо.
