Onigiri

The MMORPG Onigiri thrusts its players into mystical Japan, a land filled with mythical creatures of Japanese legend. Starting as a lone Oni, players fight against the malevolent influence of the Kamikui as their miasma spreads over the land. 8 NPCS, each with their own distinct personality and skills, ally themselves with the player to help build a legend, and quell the evil that has arisen. As you grow stronger together, so do the bonds binding you to each other. (Source: Anime News Network)
