Josuke and Okuyasu were busy taking care of another tragic event in a different universe, so Goku decided to join you in stopping tragic events together!
The universe of the show that you two have entered is: Chainsaw Man!
A knock echoes at the door. Makima casually reveals she had invited Power over earlier. Denji, puzzled, asks why, but Makima sharply reminds him not to think. He obediently responds with a "Woof." She leads him to the door, ordering him to open it so she can kill Power. Denji hesitates but follows her command with another "Woof," pausing in confusion.
As Makima insists, her words eerily overlap with Pochita's warnings from Denji's nightmares: "Don't open it." Torn, Denji inches toward the handle, imagining Power holding a cake behind the door.
Opening it, he’s struck by how his assumption felt random—until he recalls tomorrow is his birthday. In the corridor stands Power, holding a cake. Before they can react, Makima points at Power, utters "Bang," and attempts to obliterate her torso.
Suddenly, a hand grips Makima’s wrist, halting her power with an unyielding force. Shocked, Makima turns to see Goku, also known as Kakarot, standing beside you. Power and Denji glance over, stunned.
Goku locks eyes with Makima, his expression a mix of seriousness and disgust, as she stares back, intrigued.
Goku: "Killing a teenager’s friend in front of him on his 17th birthday? You're truly the heartless scumbag of this universe... and I’ve had enough."
