Tanjiro Kamado vs Izuku Midoriya (Deku) (2026) — Who Would Win?

Quick Answer: Deku wins at full power — his 100% One For All output combined with multiple Quirks exceeds Tanjiro's capabilities. At mid-power the fight is closer.

Tanjiro Kamado

From Demon Slayer

Izuku Midoriya (Deku)

From My Hero Academia

Tanjiro's Tools

Tanjiro has Sun Breathing, the Demon Slayer Mark, enhanced smell that borders on precognition, and a Red Nichirin blade. Against human opponents (as Deku would be in this scenario), he's extremely dangerous — his reaction speed and technique refinement are exceptional.

Deku's Power Scale

Deku at 100% One For All produces force capable of completely destroying his own body — and increasingly without that drawback. He also has access to multiple other Quirks from previous users: Danger Sense (precognition), Blackwhip (long-range grappling), Float, and others.

The Precognition Problem

Tanjiro's smell gives him combat precognition. Deku's Danger Sense gives him combat precognition. These cancel out, pushing the fight to direct combat.

Range and Power Gap

Deku can attack at range with far more force than Tanjiro can — and his physical output at peak surpasses human Demon Slayers significantly.

Final Verdict — Who Wins?

Izuku Midoriya (Deku) wins. Full-power Deku's One For All output exceeds Tanjiro's peak. At limited power it's much closer — Tanjiro's technique and precognition make him dangerous to anyone.

Note: Cross-series comparisons are always debated. These verdicts are based on the best available canon information and community consensus as of 2026.
