DenReze

ReJi is the het ship between Denji and Reze from the Chainsaw Man fandom.

Canon
Denji and Reze initially met during the rain, where Denji took shelter inside a telephone box. There, Reze joined him and talked about how much the rain was pouring down, which he agrees. She starts laughing, and says that his face reminds him of her dead dog, much to Denji's shock as he asks if he looks like a dog. He then starts gagging, where Reze offers a handkerchief, before Denji takes out the flower he ate before out of his mouth. Reze asks if it's magic, but Denji claims that it isn't. He pauses for a minute when looking at her face, until the rain stops and she gets out. She then invites Denji to come over at the place she worked at, and tells him the address.

He apparently gets there before she does, where he orders a water. Reze is tasked to serve it to him, and she sits down next to him, ordering two coffees, and is willing to pay. When Denji starts drinking, he makes a disgusted face. Reze, shocked, says that he's totally forcing to drink it, as he retorts that coffee is gross. She then starts laughing, calling him a kid and touching his shirt. Denji is a little surprised, and assumes that she likes him. They then exchange names, and Reze says that Denji is the most interesting person she's met. Denji thinks about how he likes people who likes him, and starts developing feelings for her. In his mind, he asks Makima for help, and that he's starting to like her.

Since then, Denji has kept coming to the shop, and tells himself that his body is just directioning him to her. Arriving to the shop. Reze invites him to sit down next to her. They then start talking about school, and Denji mentions how he's never attended, which Reze claims that that's bad. Then, she proposes to teach him, and writes down in kanji the word "balls". Denji then explains that she's a pervert, and that it's the only word he knows. Reze laughs, which puts Denji into shock, before he absentmindedly says that school would be better with her. Reze smirks and suggests going to a school with her at night. Denji happily accepts the offer, and they go together.

There, Reze talks about how she's scared at night, and asks him to hold her hand. He does, and when they arrive at the classroom, Reze writes questions on the board and asks Denji to answer them. Reze then proposes to go to the pool, before taking her clothes off. Denji gets surprised, but is then willing to get in the water with her, when she teases him and asks if he can't swim. When it starts raining, they get back inside and look out the window, where Reze says that she has to go to the bathroom. As she leaves, Denji mentions how she's "super crazy cute". While she is gone, when Denji "talks" to Pochita, and saying that he officially loves both Makima and Reze.

When Reze comes back, she invites him to a festival, where they meet privately after having fun. There, Reze says that he should quit devil hunting and life with her, which she says that she'll protect him all her life. Denji, flustered, doesn't say anything until Reze realizes that Denji likes someone else along with her. She then kisses him, but halfway through she bites his tongue off. She then takes a knife and slices his throat and cuts his hand off before he can pull his chainsaw cord. She crouches down and kisses him again, apologizing for hurting him. She claims that she has to take his heart out but before she can, Beam runs away with Denji.

After Denji saves her life and spares her, he invites her to meet him at the café but Reze refused his invitation. Later, Reze had second thoughts of boarding the train and decides to meet Denji at the café only to be killed by Makima when she's close to the café.
