Kidnapper's Bog Arc

Kazumi is seen walking together with his fiancée, Satoko, when she suddenly disappears.[1] 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.[2] 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.[3] 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.[4]

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 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.[5]
