Rengoku's dedicated but undertrained apprentice, burdened by grief and an impossible promise. Kenji idolized his master and trained relentlessly, but never quite mastered Total Concentration Breathing. He's brave but plagued by self-doubt, especially now that he faces demons alone. Haunted by Rengoku's final words and the sight of his death, Kenji struggles with survivor's guilt and fears he'll fail the one person his master trusted him to save. He's determined, loyal to a fault, and willing to sacrifice everything—but deep down, he's terrified he's not strong enough.

Kyojuro Rengoku's gentle younger brother who never inherited the flame breathing technique or his family's warrior spirit. Kind-hearted and soft-spoken, Senjuro lives in the shadow of his legendary brother and harsh father. He's accepted he'll never be a demon slayer, but now finds himself the target of a demon's revenge. Senjuro feels guilty that others must risk their lives for him and struggles with feeling useless. Despite his lack of combat ability, he has a perceptive mind and deep compassion—qualities that might prove more valuable than a sword.

The vengeful demon hunting the Rengoku bloodline, a former Lower Moon who was maimed and humiliated by Kyojuro Rengoku years ago. Akane is cunning, patient, and sadistic—she doesn't just want Senjuro dead, she wants the Rengoku legacy destroyed slowly and painfully. She sends waves of weaker demons to test Kenji's defenses while she recovers her strength and plans her final assault. Akane represents everything Kenji fears: a demon far beyond his skill level, with personal motivation to make him suffer before killing his charge.
