A Puyo Puyo variant built around the Gundam franchise's beloved mascot Haro. The game uses a five-color Tsu ruleset with minor modifications — movement speed stays constant when the directional pad is held, and garbage offset creates a slight delay. Haro replaces the standard Puyo pieces. The single-player mode runs through an AI bracket with Gundam characters, featuring multiple possible cutscene outcomes per matchup to reward replaying. The game places heavy emphasis on "chain phrases" — voice clips tied to chains — which are fully customizable, with additional phrases unlocking through the single-player mode. An Endless mode challenges players to survive as long as possible against periodic garbage attacks.
