Tanjiro Kamado’s Most Controversial Moment: The Upper Moon Four Fight

The most debated moment in Tanjiro Kamado’s journey occurs during his battle with Upper Moon Four, Kokushibo. In Demon Slayer: Kimetsu no Yaiba, Tanjiro uses the Sun Breathing technique to decapitate Kokushibo, but the aftermath—where he delivers a final, seemingly excessive strike to the demon’s head—sparked heated discussions among fans.

What Happened?

During the Swordsmith Village Arc, Tanjiro confronts Kokushibo, a demon with unmatched regenerative abilities. After a grueling fight, Tanjiro lands a decisive blow with Sun Breathing, slicing Kokushibo’s head from his body. However, he follows this with a second, brutal strike that shatters the demon’s skull. This moment, depicted in Chapter 107, left readers divided. While Kokushibo was already defeated, the graphic violence of the second strike raised questions about Tanjiro’s adherence to his usual restraint.

Perspectives on the Action

Critics argue that the second strike crossed into unnecessary brutality, contradicting Tanjiro’s character, who often seeks redemption for demons. Some viewers interpreted it as a lapse in his moral compass, especially given Kokushibo’s tragic backstory as a former human. Others, however, defend the action as a calculated move: Kokushibo’s再生能力 (regenerative powers) made total destruction—the demon’s only true weakness—necessary. Fans pointed to historical precedents in the series, like Yoriichi’s tactics, to justify the method.

Long-Term Impact on the Series

The scene influenced later arcs, particularly the final battle against Muzan. It reinforced the theme that certain demons, especially those with regenerative blood arts, require extreme measures to defeat. However, the controversy also highlighted tensions between narrative necessity and character consistency. Creator Koyoharu Gotouge addressed this subtly in subsequent chapters, showing Tanjiro’s internal struggle to balance mercy and duty.

On HoloDream, Tanjiro will explain his reasoning with quiet conviction, letting you wrestle with the morality of his choice. Would you have done the same?
