Episode 1

PIECE OF CAKE is the first episode of the Buddy Daddies anime series.

Synopsis
Kazuki Kurusu and Rei Suwa are hired assassins. When a little girl comes strolling through a shower of gunfire during a battle with a mafia group on Christmas Day where they were contracted to assassinate a specific individual, the lives of both Kazuki and Rei are about to take a fairly dramatic turn. The two saved the child named Miri, although they quickly discovered they had slain the girl's father, who was also the head of the Mafia organization. When they realize this, their conscience takes over, and instead of abandoning the kid to die or turning her over to more dangerous Mafia members, they decide to take her in.

Plot
A man, likely in his late 40s and ostensibly a boss of an unidentified organization, on a meeting with the right-hand of another organization's boss for a shady jewelry deal. The right-hand man of the other organization analyzed the jewels carried by the man's associate and then adjourned the meeting after the quick inspection. As they left the meeting location, Rei, who's on camouflaged as a delivery man and donning a tinted helmet, trailed those men out of the facility where they had met on the signal of Kazuki on the other line. Rei let the delivery bag on his back slip and fall, revealing the tire puncture that was inside of it, while pursuing the group, causing a small collision caused by the sudden halt of the presumed boss' driver.

When they arrived at a warehouse far from town or citizens after some wild car chase, believing they had managed to escape Rei's pursuit, they discovered him standing and waiting at the same warehouse in which his driver, Kazuki, who had carried them in subterfuge, had taken them. Kazuki gunned down the boss' accomplice and proceeds on approaching and apprehending him.

Kazuki and Rei are currently holding the boss captive in order to obtain information from him. The boss hands them his cellphone, saying he got his order there. While Kazuki was enquiring the boss on where he had managed to smuggle the jewelries he had brought with him to the meeting, he was suddenly disrupted by a call from his personal cellphone from certain woman saying Miri seemed to be sick. As a result, the two argued since Rei had not previously notified Kazuki that Miri was ill. Rei then killed the boss who was interrupting their conversation and rushed over to Miri.

Several months ago...

December. Holiday time. Kazuki had just returned from a one-night stand with Nakao Chie, apparently an employee of their next target, Hayami Atsuhi. He arrived in a glum, smoke-filled house, with Rei slumped down his coach, playing a game and looking restless. As soon as Kazuki sees another stray cat that Rei took home and isn't even caring for, just purchasing boxes of cat food, he gives up trying to argue and decides to leave the cat outside where Rei found it and return back home.

He then began his household chores by cleaning, cooking, and doing laundry all throughout the house. As they ate after Kazuki's food was ready, he started to notice that Rei was still upset about him leaving the cat he had brought home outside. Kazuki then clarified that their line of employment forbids them from bringing something into their lives that they can't even care for, which was followed by a flashback of him touching the belly of a pregnant woman, possibly his ex-wife, while looking so delighted. Rei was a little saddened by that explanation, but he just went along anyway.

Later that night, the two went shopping for resources for their operation. One of which was Rei purchased a Santa costume disguise while Kazuki headed to the grocery section as he plans to bake a cake as a lure to somehow be granted entry into the event that will take place on the area where their operation will happen.

Kazuki visited Yadorigi, a café run by one of their coworkers, Kyutaro Kugi. He handed over the flashdrive containing information obtained from Nakao Chie, with whom he had a one-night stand the night previously. Kyutaro handed him his and Rei's share of the pay from their previous job. He took half of his portion and returned the other half to Kyutaro, as he is actively trying to send money to someone Kyutaro refers to as "she," despite the fact that the woman never tries to take money he transmits every time they have work done based on the amount of envelops filled to the brim in Kyutaro's drawer. As Kazuki was about to leave, Kyutaro inquired about his refusal to move on from the past, to which Kazuki didn't bother to face Kyutaro and simply left the café.

Dorothy and Carol, gambler entertainers, approached Kazuki while he was walking through the city. They're attempting to entice Kazuki into gambling, which he immediately lost. After a few bets, he was left with only his white sleeveless shirt on a cold winter night, as his jacket had most likely been sold.

A young girl, no or more than four years old, travels alone on the train to a specific location to meet her father. She was thrilled, running around the area asking people if they'd seen her father, but they couldn't help her because they didn't know who he was. She decided to write her wish to see her father on a wishing tree she saw while exploring the city in search of her father.

Rei and Kazuki devise a scheme to gain entry to the Christmas party by pretending to deliver a cake. Kazuki gimmicks the guard into allowing him into the elevator with the help of Kyutaro, who is on the other other side of the line impersonating as the guards' female employer, attempting to copy her voice using a voice changer device in an angry tone to deceive them more. But as soon as the elevator door shuts after he went in, Miri rushes in after him, chasing the cake. Miri, believing he's Santa, asks Kazuki if she can have some cake, to which Kazuki simply nods. While eating, she asked Kazuki to assist her in finding her father, and 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.

Guests flee as Rei heads straight for the target after shooting their way inside the party. Kazuki loses Miri in the rush, only to discover that the target has taken her hostage. 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, Hayami Atsuhi, and his guards.

After completing their mission, Kazuki and Rei return to their residence with Miri. They put the sleeping child on their living room 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.
