Chainsaw Man (Original Japanese Version‪)‬

Denji is a teenager who lives his life as a Devil Hunter. Aiming to pay off the debt he inherited from his father, he starts hunting devils for the yakuza with his buddy Pochita, a "Chainsaw Devil", while living a tragically poor life.

After being taken into custody by Makima, one of the Public Safety Devil Hunters, Denji finds himself head over heels in love with her thanks to her suggestive insinuations. Wishing to team up with Makima, Denji arrives at the Devil Hunters Headquarters in Tokyo, and gets introduced to Aki Hayakawa, a senior hunter that he was supposed to partner with. But then Hayakawa beats Denji up, and demands that he “quit this job” ...

Denji decides that his new dream is "to fondle some boobs." His partner, Power the Blood Fiend, offers to let him feel her boobs only if he rescues her old pet cat Meowy from a devil. With his dream in sight, Denji is all fired up and ready to go, until...

After a fierce battle, Denji defeats the “Bat Devil” and rescues Power even after she had trapped him. He says it is all for the sake of “touching Power’s boobs”. Power mocks his ridiculous motivation, but still agrees to let him fondle her boobs.

Aki Hayakawa, Denji, and Power start living together. Denji finally fulfills his dream of touching Power's boobs, but is shocked when things do not turn out the way he expected.

Denji and Tokyo Special Division 4 members enter a hotel to collect a piece of the Gun Devil. However, they end up being trapped on the 8th floor due to the devil's extraordinary power.

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.

Denji experiences his first, yet devastating, kiss. An intoxicated Denji is taken to Himeno's house, where she starts seducing him. Torn between Makima, whom he admires, and Himeno, who is standing in front of him, he decides to fall into temptation.

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.

Samurai Sword's vicious attack resulted in many lost personnel for Public Safety Devil Extermination Division 4. Aki Hayakawa wakes up in a hospital bed, unable to accept the reality of losing Himeno.

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