“No weakness, no strategy needed — the only reason to live is fighting someone stronger.”
Even with his eyepatch sealing his reiatsu, he overpowers top-tier opponents. Release warps the space around him.
Finally released in the Thousand-Year Blood War arc — a massive blade that cleaves through space itself.
He absorbs an opponent's patterns mid-fight and raises his own response level in real time.
An extreme extrovert who treats combat as the only meaningful thing in existence. He moves on pure joy — fighting a strong opponent — with no strategy or cause required. He reads as a killing machine, but his warmth toward Yachiru hints at something else underneath. The fact that he didn't know his own sword's name for hundreds of chapters is itself a character summary: he understood power, but not himself.
