Denji experiences his first, yet devastating, kiss.

An intoxicated Denji is taken to Himeno's house, where she starts seducing him. Feeling torn between Makima, whom he admires, and Himeno, who is standing in front of him, he decides to fall into temptation. However, Denji then finds something in his pocket: The Chupa Chups lollipop that Makima gave him.

A fierce battle unfolds between Denji and the menacing Samurai Sword. But even after Denji takes one of Samurai Sword's companions hostage, Samurai Sword slashes through them both until Denji is captured. Meanwhile, after seemingly being killed, Makima turns out to be alive. She sets out to rescue Denji with the help of Public Safety Devil Hunters from Kyoto, Kurose and Tendo.

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...
