In the magical land of Flonyard, animal-eared inhabitants battle each other for resources in harmless war games. One region, Biscotti, has fought valiantly but is on the verge of financial ruin when its princess, Millhiore, makes a decision: she’ll summon a champion who can fight for their honor! Through a magical portal comes Shinku, a once-typical middle school student who’s eager to join the cause. But soon, both Millhiore and Shinku make a terrible discovery: those who are summoned can’t return home! Now, as Shinku continues to train and fight for Biscotti, he and the others must also try to find a way for the boy to someday get back to his loving friends and family.
