Kurusu Family

Kurusu Family is the family ship between Rei Suwa, Kazuki Kurusu and Miri Unasaka from the Buddy Daddies fandom.

Canon
Buddy Daddies centers on a family of three who aren't related to each other: Kazuki Kurusu and Rei Suwa, assassins who live under one roof; and Miri, the daughter of Kazuki and Rei's assassination target who ended up being picked up by Kazuki, who she thinks is her biological father.

Rei and Kazuki met at the Yadorigi coffee run by Kyutaro, and since then Kazuki moved to Rei's residence to live with him. Three years later, on Christmas Eve, both of them are scheming to gain entry to the Christmas party by pretending to deliver a cake. Kazuki disguises as Santa and brings the cake in a cake trolley to an elevator (with Rei being hidden underneath the trolley). As soon as the elevator door shuts, Miri rushes in chasing the cake. Kazuki worried sees Miri, telling Rei a kid is on the elevator. The little girl, believing Kazuki is Santa, asks him if she can have some cake, to which he nods. As Kazuki feels moved by Miri's happiness, he starts telling Rei how happy the kid looks, while he is simply confused listening to him. Suddenly Miri asks Kazuki if her wish became true (of finding his father), to which he agrees at random. She runs out of the elevator with full of excitement as soon as the doors open, notifying the security upstairs. Rei shoots them both from underneath the cake trolley, asking Kazuki which of both is the kid he was talking about. Kazuki obviously tells him none of them and runs off for the little girl.

Guests flee as Rei heads straight for the target after shooting their way inside the party. Kazuki loses the girl's sight in the rush and asks Rei for Miri, but he doesn't recognize that name (since only Kazuki heard it). When they discover their target has taken Miri, Rei suggests shooting the target through Miri, but Kazuki objects out of fear for her life. Desperate, Kazuki frantically exclaims, "I'm your papa!" and rushes to her aid, trying to shield himself from a henchman's gunfire with a food tray. Rei shoots the target's legs, loosening his grip on Miri and allowing her to jump into Kazuki's arms. When Miri is secured, Rei manages to shoot the target and his guards.

After completing their mission, Kazuki and Rei return to their residence with Miri. They put the sleeping child on their sofa while Rei chastised Kazuki for being able to bring a kid at home when he was not being given permission to have a cat. In order for them to determine Miri's identity, Kazuki went through her bag and had discovered some pictures in it. The photographs revealed that the assassination target they gunned down at the derailed Christmas party was her biological father.

Since then, Kazuki and Rei have to deal with the problems of being parents: having to take care of the girl, help her go to the bathroom, feed her, pick up and clean up after her, and have to deal with the mess that she starts leaving around. Even when they try to take her on a job with them, she causes a mess and their plan gets ruined. Despite everything, it can be seen that little by little the two began to grow fond of Miri, as when they were looking for her mother, they both doubted if they really wanted to let her go. But after Miri says some important words for Rei's life, and Kazuki has a heated argument with Misaki, Miri's biological mother, both Kazuki and Rei accept their new life as the little girl's parents.

After several months have passed, we are shown that they are already like a real family: Kazuki and Rei managed to get Miri to the kindergarten, they live their daily lives together, and Miri is already used to addressing both of them as "papas". Although at a certain point they come to have problems, since Kyutaro finds out that they are taking care of a girl, and warns them that they can bring danger and consequences to the people they put into their lives, and when he asks Kazuki and Rei if they are willing to accept it, they affirm.

One day Kazuki decides to leave the house for a while, feeling that neither Rei nor Miri appreciate the work he does (since he is the one who cooks, cleans and washes) while they never thank him. As Kazuki leaves, Rei and Miri realize how much they miss him, and how their home and life is a mess without him. When Kazuki comes back, they try to cook him a french toast, but they horribly failed and Kazuki angrilly scolds at them, but with a smile on his face as he knows both Rei and Miri did their best, and at last, he was back at his home.

For a while now, Kazuki has discussed how Rei tends to "steal him credits" as Miri sees Rei as the father Which she plays videogames and laughs the most (something Rei clearly likes as he smirks about it), but is also grateful that Miri sees him as the protective father who makes the best dishes. Even after Misaki came back to take Miri from them, something that left the two men heartbroken, Miri even told her the same thing: "papa Rei is super good at videogames and papa Kazukimakes delicious bentos," and even told her mother her desire for all of them to live together. Sadly it wasn't able to happen, since the organization where Kazuki and Rei work for sent their man Ryu Ogino to kill Miri, and in that action he killed Misaki. After this, Kazuki and Rei take Miri back, but Kazuki suggests to erase everything from Miri's past. Rei, not wanting to leave the family they made, convinces Kazuki to keep her, and for this time, becoming a real family.

The next day, they live Miri at her daycare, as she is having a Christmas show that night, and prepare to take down the organization, and in a face-to-face between Rei and his father, he tells him how he learned the true meaning of the word family, and how he will always protect Kazuki and Miri no matter what. In a timeskip, we see that Kazuki and Rei could made their wish come true, and after moving from their former residence, they open a diner together with a now teenage Miri, revealing us they finally became the family they always wanted to be. The anime closes with Miri asking her dads for a photo.

Fanon
In most part, Kazuki parallels Loid Forger and Rei as Yor Briar, with the addition of Miri as Anya, but both are in actual hitmen raising a female child, keeping their real jobs as a secret from her, this trait also shared with Loid and Yor, who are a detective and an assassin respectively. Fans would call the anime "Gay x Family" or "SxF but gay", since the main characters (both guys) raise a kid together (Miri), which'd complement with Loid and Yor's relationship with Anya as a family. Also Kazuki's cooking skills is one other trait that makes him similar to Loid, as both know how to cook while their partners -Rei and Yor respectively-, don't. Both Kazuki and Rei often argued on who has to take care of Miri, putting the job to the other, taking turns in occasions. Despite no canon confirmation over if Kazuki and Rei's actual relationship is romantic or not, what is true is that the three of them are now living happily together as a family.
