DenPower is the friendship between Denji and Power from the Chainsaw Man fandom.

Canon
Denji and Power first met as "buddies", where Makima assigned them together. Power had initially looked down upon Denji as his status as human, and ordered him to grovel before her. Makima had warned that she was a fiend beforehand, which confused and shocked him, asking if fiends can be devil hunters. While he was at first reluctant to work with her, he changed his mind after looking at her breasts, and looked forward to it. On their mission, Power was extremely energetic, and had slapped Denji's head, demanding blood. He gets extremely annoyed, but said that he should forgive a pretty girl. The two then rest, where he asks where the devils are, to which Power responds by saying that it's thanks to her, due to her being a fiend. She then smelled blood and ran over to the scent, where Denji had to run after her. Arriving at the edge of a building, Power jumped off it and created a hammer using her powers, and killed it. Later, Makima came over to them and said that they had broken the law. She then told Denji that he should keep her under control, which angered him. Makima then tells Power that she may not be suited to be a devil hunter, which stresses her as she blames Denji and falsely accusing him of ordering her to kill the devil. They then get into an argument, until Makima asks the two to be quiet, which they do. Later, they take a break and buy drinks, where Denji claims that buying soft drinks is a dream come true, although it is interrupted by Power claiming that she hates humans, due to her devil instinct. She follows by saying that she only gets along with cats, before picking a random cat up and explaining her story with her cat, Meowy, who was captured by a devil. Denji at first thinks that the topic is uninteresting, before Power offers him to feel her chest if he saves her cat. He gets excited, although on their way to where the devil is, the two get into an argument, which causes the two to go silent after Power mentions that Pochita is dead and that nobody can bring the dead back. Denji then thinks about how he could never be friends with her, and the two arrive to the house in silence. As they walk towards it, Denji asks about her cat, and how the devil may use it as a hostage. Power then said "Ohh, that was my story?". Denji, confused, asks what she means, before he figures out she's lying and attacks her, Power making a smaller hammer and hitting him in the head, knocking him unconscious. She drags him to the house, where the devil awaits for a human. She then gives him to it. Upon drinking some of his blood, it becomes angry and calls his blood disgusting, dropping him to the ground. Power tells Denji that she couldn't believe he trusted her, and told him that humans really were foolish. Then, the devil eats the cat, breaking their promise. Power tells Denji that she understands how he feels, not being able to pet Pochita anymore, before she gets swallowed too. As the devil flys away, he latches onto it's leg, and tells it to bring her back, refering to her as his "boobs". When he does get her out, and saves Meowy, he can be seen holding her, and she asks him why he saved her. He hesitates before pointing at her breasts, which Power mocks him for and tells him that it's a really stupid reason. Another devil attacks from behind, and Denji attacks it, although his chainsaw isn't powered, due to the lack of blood he's injested. Before Denji can get hurt any further, Aki steps in and saves him. He is then taken to the hospital, where Power awaits outside for him.

Later, while Denji and Aki are home, Power barges in and mentions how tiny the house is. It is then said by Makima that she sent her there. When eating vegetables, Power is disgusted, and throws them at Denji's face. He then mentions how offending it is to the farmers who made the vegetables. Later, Denji cleans the toilet after Power didn't flush, and says that she's the worst. Power then comes in, and Denji calls her the "shit devil", asking what she's doing here, before she points to her chest and tells him that he can feel it if he'd like. She sits on the toilet seat and tells her that he can squeeze them, before Denji tells himself that she's an angel. Power tells Denji that he can only squeeze three times, one for saving Meowy, two for defeating the devil, and three for covering for her. When he does, Power tells him to stop after the third, and he is left shock, wondering if that's it. She then puts her arm around him and tells him that they're even. She then leaves, and goes to bed.

Along with the other members of their squad, Denji and Power are assigned to a mission, where they are tasked to exterminate a devil at a hotel. Standing in front of the building, the two are reluctant to go inside, and follow Aki's orders, until he pulls gum, causing the two to listen to him.

Fanon
Denji and Power's friendship is incredibly well received inside the fandom. Many have said that shipping them romantically is extremely strange, as the author has said that he rather keep their relationship as a brother-sister like one, and that Denji has stated that he doesn't feel anything naughty about being in the same bath as her, despite his usual lustful thoughts. Many believe them to be platonic soulmates, and Power's death has greatly impacted onto Denji. After she did die, the fandom became devastated. Due to this, fanfictions and artwork often show angst, and Denji heavily mourning over Power's death.
