Embark on a tale of heroes and spirits in RPG 双翼世界の精霊勇者. Summoned spirits, magical battles, and a world on the brink of chaos await players in this captivating game. The clash between "hero" and "demon lord" has disrupted the balance of the world. As the hero, Licht, accidentally traps the summoned spirits in the human realm, they risk turning into monsters. To prevent this, Licht sacrifices his body to host the spirits, setting off on a quest to find the vanished demon lord.

Players can summon spirits randomly to cast spells and forge contracts with them for ongoing support. By leveling up spirits, mastering powerful magic, and evolving them, players can harness their combined strength to face formidable foes. Using the mystical "Sky Magic Stones" found during adventures, players can absorb enemy skills, manipulate their health, and inflict status effects to enhance their combat strategies.
