X-Stream is an attack used by Tsuna. Tsuna dives down at his enemy and rapidly begins to circle them from bottom to top, Flames lagging behind his feet, until his target is completely trapped in a tornado of Sky Flames. This move was only used once during his fight with the Death Stalk Unit under Iris of the White Spell. It was capable of separating the merged Death Stalk Unit members back into their individual forms.
