1. Boss Overview

Ifuu is a wind demon — agile, evasive, and built around controlling space with pressure waves. He favors mid-range combat where his wind slashes and projectile blasts can cover wide arcs. Unlike Burai, whose lightning is a deflection mechanic, Ifuu's wind attacks are best handled with positioning and patient defense.

He appears solo in his main story encounter inside sacred grounds, then later pairs with Burai in a duo fight. Both encounters test the same core skill: read his wind cadence, do not commit early, and punish the recovery.

2. Two Encounters

Encounter 1 — Sacred Grounds

Ifuu's solo encounter is set in a wide sacred-grounds arena. He cycles through wind slashes, projectile volleys, and aerial dashes. The Howling Wind trophy unlocks for clearing this encounter.

Encounter 2 — Duo with Burai

Later in the story, Ifuu returns alongside Burai. The duo fight forces you to manage two elemental threats at once: wind + lightning. The Perfect Storm trophy unlocks for clearing the duo.
