Jun Sadamoto

Jun Sadamoto (, Sadamoto Jun) is the deuteragonist of The Kaito Files, a Lost Judgment story expansion. He is the son of Kyoya Sadamoto and Mikiko Sadamoto.
== Profile ==
=== Appearance ===
Jun is a short, athletic young man. He has dyed red slicked back hair.
==== Attire ====
Jun wears a black sherpa lined zip-up denim trucker jacket that features a red tab on the left chest pocket (mirroring the Levi's brand red tab on their denim jackets), a gold chain necklace, a white t-shirt over a longer orange t-shirt, black sweatpants, and tan-colored work boots.
=== Personality ===
Jun looks up to Kaito due to him reading his mother's diary full of stories of Kaito. He frequently runs away from home due to his biological father, Kyoya Sadamoto, not caring for him and barely even noticing if he's gone. He often steals watches from his father to sell and despite his age, he smokes Hope brand cigarettes like Kaito. 
He is cocky and hot-headed, but he has a heart of gold. If he sees someone being treated unfairly, he will stand up for them despite how outnumbered or outclassed he is. Examples include standing up for a worker at Charles who was being sexually harassed, chewing out men in Cafe Alps for smoking cigarettes with a baby in the room, and standing up for a woman who was being sexually harassed on the street. He wants to become stronger so he can be like Kaito.
== Background ==
Jun is suspected to have been conceived to push Mikiko into marrying Kyoya Sadamoto. As a child, Jun one day ignored his father Sadamoto's warning to not play with his knife collection, which caused Sadamoto to make a shallow cut on the boy's arm as a warning to him of the dangers that knives pose. This caused Jun to develop a fear of knives. Due to Sadamoto frequently not being home, Jun's relationship with him was poor. One time, he left home for a week and his father had not noticed.
While he was in elementary school, Jun would frequently read through his mother's diary. He saw how she described Masaharu Kaito as a real-life superhero, and aspired to one day meet Kaito. He also read an entry of her discussing whether or not to "keep it" written shortly after her breakup with Kaito; a line interpreted by Jun as her thinking of whether or not to keep him while pregnant and causing him to think Kaito is his true father, though in reality Mikiko was discussing the ¥50,000 she had borrowed from Kaito and had not paid back.
During an argument with his father, Jun states his belief that Kaito is his biological father. When news of Mikiko's suicide reached Jun, he was heartbroken over it, but did not fully believe it because he felt Mikiko would never leave him behind. Two years later, reports of Mikiko being sighted in Kamurocho caused Jun to run away from home in search for her. He left behind his cellphone to not be tracked by his father. He also stole one of Sadamoto's expensive watches to pay for compensation.

=== The Kaito Files: 2022 ===
Jun searches Kamurocho both for leads on Mikiko as well as Kaito. During his search, he visits Charles, saves a homeless man from thugs, and has a run-in with the Bato Detective Agency. On his second visit to Charles, he meets Kaito, who went there after being asked to put a stop to the trouble happening there. He asks Kaito to look for his mother, but the detective declines. Jun then tells Kaito what he reads in Mikiko's diary; her desire for Kaito to leave the yakuza as well as him potentially being Kaito's son.
Kaito eventually agrees to Jun's request to look for Mikiko. While searching for her, Kaito talks about his past with Mikiko and starts to act as a father figure to Jun. Jun's heroics frequently put him in danger, which require Kaito to resolve. Eventually, they encounter the same Bato thugs Jun met earlier, and they take him away. Kaito is able to find Jun, but the Bato detectives point their guns at them. Knowing they need him alive, Jun escapes through the window and asks Kaito to meet him later.
At the Batting Center, Kaito lectures Jun for behaving so recklessly and plans to contact Sadamoto to have him be picked up, but Jun swallows Sadamoto's business card to stop Kaito and affirms his resolve to find Mikiko. When asking how he can protect those he cares about without being yakuza, Kaito tells him to keep the fire in his heart burning. Kaito allows Jun to continue following him, and a new lead takes them to the Shirakaba Clinic. 
Yasutaka Shirakaba confirms Mikiko's death, but Kaito's suspicion makes Shirakaba reveal she is, in fact, alive. He had helped her fake her death to protect her from Crimson Lotus, who wanted to find her. After hearing Shirakaba's explanation, Jun asks why he had not contacted him after learning of Mikiko, making him admit he fell for Mikiko and did not want her to leave him should she learn of her identity. Crimson Lotus arrive, and Jun and Kaito head back to Kamurocho alongside Shirakaba after learning she had killed Crimson Lotus's founding members.
After seeing Mikiko on top of a burning building facing down office workers, Shirakaba pieces together that they were Crimson Lotus founders. Jun accompanies Kaito in his investigation and stakeout of Shusuke Kenmochi; Mikiko's next possible target. When they learn Kenmochi had baited her, Jun is told to return to the office by Kaito, as the danger is too much for him. When he is filled in on what Kaito learned of Mikiko and that she is not a killer, he is relieved. They spend time together before Kaito searches for Mikiko in Ijincho and Jun is left behind.
However, Jun is not safe as Kenmochi kidnaps him on Sadamoto's order. He is taken to Sadamoto in Ijincho where Jun is held hostage at knifepoint. Before anyone can be killed, Jun recalls Kaito's words and is able to break free. This allows Kaito to defeat Sadamoto, and the later is killed by Kenmochi. Kaito is hospitalized from Sadamoto's poison, and Jun watches over him alongside his mother, who is taken away be Shirakaba later to get some rest, though Jun decides to stay with Toru Higashi keeping him company. Shirakaba also gives Jun a letter to pass to Kaito.
Jun, after Kaito wakes up, is taken by him to discuss the death of his father. He recalls a memory where Sadamoto drove him far to the ocean in a new car. He resolves to be strong, and Kaito comforts the boy. Jun then gives Kaito the letter, and they head to Shirakaba's clinic. After exchanging words with his mother, Jun witnesses Shirakaba duel Kaito to have Mikiko's love, then sees Kaito and Mikiko make up. He presumably accompanies them to a new residence afterward.
