The opening starts with Denji pulling his cord, with the classical painting "The Divine Comedy" in the background. The scene shifts to Denji, Makima, Power, and Aki frozen still in the city before they begin to move.

Various scenes begin to play rapidly: Denji cradling Pochita in a graveyard; Kishibe pointing a gun; Chainsaw Man and Katana Man fighting; Galgali taking off a shoe; Aki and Denji backing out of a driveway; Kobeni climbing off of a table as Hirokazu gets on; Denji looking horrified as Power laughs in the background; Angel Devil sitting on stairs before looking up at the camera; Himeno and Aki standing on a rooftop.

The main cast are shown watching a movie in a theater, with Angel Devil, Beam, Princi, and Kishibe seen in the background - Kobeni leaves her seat to go the bathroom and Power steals her seat and drink. The scene then cuts to Denji, Power, Makima, and Aki at a bowling alley. Denji polishes his ball as Aki's ball smashes into the pins, which rapidly transition into space before turning into a pin-up of Power on a beach. The camera zooms into Denji being walked like a dog by Makima before the scene is eaten by the Snake Devil as Sawatari and Katana Man's human form look on. The scene cuts to looking overtop a snowy mountain as the Gun Devil's bullet-tendrils swirl around before cutting to Denji and Makima in a library. Makima pets Denji as various plants begin growing on his body, and the camera cuts to his perspective as he stumbles towards Makima (with part of the screen blacked out, referencing his missing eye), who is revealed to be a reflection in water. The scene cuts to the two in the library again as Makima reaches towards Denji. A chainsaw emerges from his forehead as Makima does her signature pose. Denji transforms into Chainsaw Man as the scene rapidly cuts between his transformation and Makima feeding him a snail with strobing eyes.

As the chorus kicks in, the scene cuts to Chainsaw Man fighting a Devil in the city. Power joins in, and Aki watches as Chainsaw Man is thrown into a building, his holes forming the letters CSM. The scene cuts to Chainsaw Man bursting out of the Eternity Devil before returning to the earlier fight. As Chainsaw Man watches, Denji's face flashes on screen before the camera moves to Power, who sends a large golden ball towards the Devil with her hammer as Chainsaw Man rides on top, jumping to finish off the Devil.

The scene then cuts to Denji cooking Makima's flesh before the camera zooms out of the door in his mind and returns to rapidly transitioning between scenes: Power walks away from Aki as an explosion happens in the background; a young Denji sleeps with Pochita; younger versions of Power and Denji play with food as a snow-covered Aki stands on a pile of snow next to them, with Makima standing on an even bigger pile of books to look over a wall; the Future Devil dances in its room; the Ghost Devil grabs a lamppost; Katana Man spreads his arms as blades swing around him; Power and Denji dance as Aki watches, before the camera moves behind them - Aki turns towards the camera and summons the Fox Devil, who devours the camera from off-screen and the anime's logo appears.

Today is my lucky day because the laundromat is empty I can finally get rid of this grease stain Who’s that voice in my head calling out? Saying, “I want this! I want that!”

I want to be happy I want an easy life I want to hold in my hand What’s inside your heart

Just fill it in with happiness Let’s keep going until “Rest in Peace” I once dreamed of a nice place in hell Spreading love all around I Love You, so talk down to me Take it all away and laugh at me, my honey

Effort, The Future, A BEAUTIFUL STAR Effort, The Future, A BEAUTIFUL STAR Effort, The Future, A BEAUTIFUL STAR I’ve forgotten something…

Effort, The Future, A BEAUTIFUL STAR Effort, The Future, A BEAUTIFUL STAR Effort, The Future, A BEAUTIFUL STAR Effort, The Future, A BEAUTIFUL STAR

Yo, yo, yo, 3! And the soda water pops off My hunger worsens, I’m about to puke up my life As if there’s no end to the rain, give me an umbrella beforehand I want this, I want that, I want everything, I just feel empty!

I want to be happy I want an easy life I want to mess it all up I want to delete everything That’s inside your heart

Just fill it in with luck Let’s keep going until “Rest in Peace” I can’t live in a heaven That only welcomes good boys and girls I Love You, so talk down to me, moan for me Smile for me, my honey

Effort, The Future, A BEAUTIFUL STAR Effort, The Future, A BEAUTIFUL STAR Effort, The Future, A BEAUTIFUL STAR I’ve forgotten something…

Happy, lucky Hello, baby! I want to be a good boy But that’s so boring Happy, lucky Hello, baby, so sweet!

Effort, The Future, A BEAUTIFUL STAR Effort, The Future, A BEAUTIFUL STAR Effort, The Future, A BEAUTIFUL STAR It kinda feels really good!

Effort, The Future, A BEAUTIFUL STAR Effort, The Future, A BEAUTIFUL STAR Effort, The Future, A BEAUTIFUL STAR Effort, The Future, A BEAUTIFUL STAR

I was given the opportunity to write the song "KICK BACK" for the anime adaptation of Chainsaw Man. I am honored because I loved the original work. This work has tremendous power, so it was very difficult to find a suitable sound for it. I hope you will enjoy it. Thank you very much in advance.

 * The insect on top of Denji's head appears to be a jade wasp (Ampulex compressa), which parasites the cockroaches with its own larvae. In the same scene, the snail Makima is feeding Denji shows symptoms of parasitic disease from Leucochloridium paradoxum, a worm that parasites snails. These two animals could be an allegory of Makima as the Control Devil attempting to "parasitize" Denji's mind and control his actions.
