The goddess Listarte, savior of Geaburande, calls her hero for help—and naturally, he appears. The hero is named Seiya Ryuguin, and he’s a master at games, though comically cautious. For example, the guy bought three sets of armor: one to wear, a second for backup, and a third as a backup for the backup. Besides that, Seiya hoards an unimaginable number of items, sits in his room, and does nothing except constant physical training. All for one thing: to gain the maximum possible power and fight only when he is completely sure he will win. The main rule—no risk at all!
