BackGuiner: Yomigaeru Yuusha-tachi: Hishou-hen Uragiri no Senjou

BackGuiner: Yomigaeru Yūsha-tachi - Hishō-hen "Uragiri no Senjō" is a turn-based mech strategy game and the second part in an planned episodic trilogy, though the third part was never released, leaving the story incomplete. It is a direct continuation of the first BackGuiner game, telling the next portion of the story, and consisting of essentially the same strategy gameplay. A notable new gameplay feature is the ability for both Shin and Natsumi to transform into so-called "Guiner" forms under certain conditions, which temporarily boosts their combat abilities.

The game includes the ability to import character progression from the first episode; there is also a "digest" mode to catch new players up on the story who may not have played the first part. Also included in this release is an easy mode which allows strategy-game beginners to enjoy the story.
