Seiya Ryuuguuin lives by the motto "you can't be too careful" and takes it to heart no matter how small the situation is. In his RPG games, he goes above and beyond to surpass his opponents' levels to ensure victory. Seiya's personality perfectly reflects this famous phrase. Ristarte summoned him, a goddess, to rescue the doomed world of Gaeabrande. Despite having impressive stats, he puts extreme effort into preparing for his mission. He trains relentlessly, fights weak enemies with his strongest moves, and hoards excessive supplies and potions. Although his over-cautious demeanor can be bothersome, it might be the key to saving Gaeabrande. In a world dominated by evil forces and unpredictable scenarios, Seiya's unyielding vigilance could be priceless.
