“The "Demon of the Mist" — Hidden Mist's deadliest swordsman. He claimed to feel nothing, but Haku proved him wrong to the very end.”
Eliminates sound and targets vital points one by one inside dense mist — the Hidden Mist's deadliest assassination technique.
A massive cleaving sword that heals its own chips by absorbing the blood of those it cuts — one of the Seven Swords.
Traps a target inside a sphere of water indefinitely — Zabuza can maintain it from outside the prison indefinitely.
A massive water dragon launched at the target — a high-rank Water Release that shocked viewers when Kakashi mirrored it in real time.
Not a man pretending to feel nothing — a man who genuinely believed it. He categorized Haku as a tool to avoid admitting to a bond. But the tears that fell at Haku's death revealed something even he didn't know was there. He's the first character in the series to receive Naruto's empathy and actually let it land.
