Kazumi

Kazumi was a minor character in Demon Slayer: Kimetsu no Yaiba. He was a villager whose fiancée, Satoko, was kidnapped and eaten by the Swamp Demon.

Appearance
Kazumi is a young man with dark-brown hair and brown eyes with white pupils. He wears a dull, blue kimono with a dark sash and light-brown haori. He was eventually seen with bruises in his face.

Personality
Kazumi was shown to be a loving and kind person who enjoys spending time together with his fiancée. Despite his grief over her disappearance, he was shown to be quite trusting, as he believed in Tanjiro's way of trying to find Satoko. Upon learning that she was in fact dead and Tanjiro had encouraged him to move on, Kazumi became upset and asked how he could know his pain, only to quickly realize his saviour did indeed endure a terrible loss as well, becoming regretful of his harsh words.

Unlike most civilians, Kazumi seemed to know about the ancient war between demons and Demon Slayers, as he realized that Tanjiro was a Demon Slayer upon seeing his incredible physical abilities.

History
At some point, he met and got engaged to Satoko.

Kidnapper's Bog Arc
Kazumi is seen walking together with his fiancée, Satoko, when she suddenly disappears. During the next day, while Kazumi is walking with a dejected expression in town after a severe beating from Satoko's father, Tanjiro Kamado approaches him and asks for specifics on his situation. Kazumi shows Tanjiro the place Satoko disappeared, thinking he wouldn't be believed. However, Tanjiro ensures him that he does believe his word. As Tanjiro picks up the scent of the demon and runs after it, Kazumi follows, confused and later surprised, with Tanjiro's physical abilities. Tanjiro manages to save Tokie from the demon and entrusts her to Kazumi. After Tanjiro has a brief scuffle with the demon, Kazumi demands the demon to return Satoko. The demon shows his collection of hairpins from girls he had eaten and Kazumi recognizes Satoko's hairpin, realizing with despair that she was devoured.

With Nezuko's help, Tanjiro defeats the Swamp Demon. He checks if Kazumi is alright and tries to comfort him, saying that no matter how much loss he goes through, he must continue living. Kazumi, still shocked by the confirmation of his fiancée's death, questions Tanjiro how he could possibly understand him. However, through Tanjiro's continued understanding and tolerance, Kazumi realizes that he too, had suffered through the loss of someone(s) important to him. Right before Tanjiro leaves, he gives the cloth with all of the hairpins. Kazumi takes the cloth, and apologizes for saying he hadn't suffered, while thinking to himself that Tanjiro shouldn't have had to experience such devastating loss as a young child, and notes his hardships through the scars and roughness of his hands, though still impressed upon by his ever kind eyes.

Entertainment District Arc
While Tanjiro is fighting against Upper Rank 6, Daki, Kazumi briefly appears in his memory as someone he doesn't want to go through a bad experience again as a result of Demons.

Abilities
As an ordinary human and non-Slayer, he doesn't possess any additional powers or abilities.
