Yukine (雪音) is Yato's new shinki and found him as an uncorrupted wandering spirit. When he is called by his shinki name "Sekki" (雪器), Yukine transforms into a silver katana. His name is "Yuki" as a regalia and formal name as "Yukine".
Yukine has bright golden-orange eyes and relatively long blond hair that extends to the the bottom of his ears. He has the form of a teenager and is shorter than both Yato and Hiyori.
Upon his first summoning, Yukine wears a simple white robe and white socks. His first real set of clothes consists of a blue hoodie over a purple shirt, loose dark grey jeans, a white and teal snow cap, and light grey shoes.
In Episode 05 of the anime, he changes his attire to a white T-shirt, dark blue jeans, and a green knee-length jacket with orange inner lining and a fur-rimmed hood.
In shinki form, he turns into a long silver katana with the handle wrapped in white bandages, the bandages still extending loosely to the blade.
|After he is shattered by Vaisravana, he transforms into a set of two katana. The new second blade is shorter than the first but has the same design.|
Yukine is first portrayed in the manga as being a bit cold and cruel, although in the anime his coldness is toned down. He is clearly upset and annoyed at the fact that he died, and became Yato's weapon, complaining about staying with someone like him. As a result of this and the fact that people cannot see him well, Yukine takes advantage of this and other people, stealing money, clothes, and even betraying Hiyori. Yukine though seems to feel jealous over others who are alive, upset about the fact that he is dead and cannot make friends and learn what other students do. He is also apparently afraid of the dark.
|When Yato is forced to punish Yukine, Yukine confesses all of his sins and apologizes sincerely, and escapes the temptation that hurts Yato as his shinki. Yukine is visibly more upbeat after his punishment, befriending Hiyori more and requesting to learn what she does in school. Yukine also is more dilligent in his work as Yato's shinki, working part time for Daikoku to earn money for the two of them. Despite this Yukine is still a bit sarcastic and ocassionally stabs Yato when upset, especially after one of his few friends, Suzuha, dies.
When Yato makes Yukine his Shinki, Yato experiences the forgotten memories of Yukine when he was human and cries in reaction to it, indicating that Yukine had a hard life before his death, although as of now, Yukine still doesn't remember.
It is vaguely shown that Yukine had a family, but his mother and sister left, leaving him in the custody of his father. Although how Yukine died is currently unknown, the flashbacks may indicate that Yukine was possibly beaten and neglected by his father and later died of his injuries.
From then on, Yukine wandered aimlessly as an uncorrupted spirit before being found by Yato.
While fighting phantoms, Yato realized that with the absence of a Shinki, he would not be able to fight. Later though, Yato is able to retrieve Yukine, give him a name, and defeat the gloom. Yukine materializes into his human form and is given a name by Yato. Yukine realizes that he's dead, and continues to berate Yato as being a terrible owner.
Yukine manages to hate Yato to the point of wanting to separate from him, asking Tenjin if he could work for him instead. Tenjin explains the actions of that would cause Yukine to become a stray, so Yukine is forced to continue to work for Yato. Yukine gives into temptation many times, the action of doing things wanted that becomes a sin (stealing for example), and the temptation hurts Yato physically, creating warts and cuts around his body. Yukine continues to steal and exploit until Yato finally collapses. Hiyori, furious at Yukine's actions, takes Yato and forces Yukine to come to Kofuku's home where they commence the punishment.
Yukine, now in acceptance of his actions and sins, becomes noticeably more upbeat. He works for Daikoku part-time in an effort to raise money for him and Yato, and begins his tutoring with Hiyori, learning the material that she does in school. His loyalty towards Yato is heightened and willingly does what he asks.
|He later learns of his good friend, Suzuha's, death and it sends him into depression, but he supresses it enough so Yato won't feel it too much.
When Hiyori was kidnapped, he quickly follows Yato to help rescue her. Yato runs into Vaisravana and a fight commences between the two, with Yukine become a katana once again. Despite his loyalty to Yato, he still is hesitant to hurt other Shinki since they were flesh and blood like him and dulls his blade, but Yato manages to convince him to sharpen himself so he could help save Hiyori. At one point during the fight, Yukine is knocked out of Yato's hand and Vaisravana goes in to kill Yato after he is restrained by corrupted shinkis. At the last second, Yukine appears in front of Yato to take the blow for him and is shattered into two pieces, apparently killing him. Although appearing to be dead, Yukine returns as a dual wield Katana, having changed form because of his devotion and loyalty to Yato and helps him in the fight against Vaisravana.

Yukine is Yato's regalia, in Yukine's opinion, he thinks that Yato is creepy, annoying and too self-centered, after Hiyori consults Yukine and tells Yato to treat Yukine like a human being with feelings and emotions, so that Yukine wouldn't feel like a tool. After Yato receives the message, his relationship and trust between Yukine and himself slowly grows although Yukine still thinks he's annoying.
