Also known as: ストームフォーム
This is one of the forms of Kamen Rider Agito.
He is characterized by a blue discoloration of his chest armor, left arm, and the center of the buckle of the Altering (Agito).
He has less physical strength and defense than his Ground Form , but has enhanced running and jumping ability.
His weapon is the Storm Halberd, a Glaive (Polearm) with foldable blades at both ends.
His special move is the Halberd Spin, in which he creates a gust of wind by swinging his Storm Halberd and then slashes the enemy.
