“Silent, cold, alone — and yet he was the one who decided to let Nezuko live.”
A form only Giyu developed — the eleventh of Water Breathing. In perfect stillness he slashes every incoming attack. No other Water Breathing user can perform it.
Flowing, continuous slashes — the same lineage as what Tanjiro uses, but Giyu's mastery is categorically higher.
