The goddess Listarta, savior of the world of Gebrand, calls for help. And naturally, the hero appears. His name is Ryujin Seiya, and he is a master of games—yet ridiculously cautious. For example, he bought three sets of armor: one for wearing, a second for backup, and a third for the second. In addition to accumulating an immeasurable number of items, Seiya spends his time sitting in a room and doing nothing but constant physical training. All to build up the maximum possible strength and fight only when he is fully certain of victory. The key rule: no risk!
