Tenkuu no Tobira

A mythical location known as Heaven Door is said to fulfill any wish, though the outcomes can vary from blessings to nightmares. After Ray, a lightning champion, and his allies defeated King Diablo, the demon king who attacked the human world, peace was restored. However, the heroes were soon poisoned, including Roush Moderia's father, a top "Macro Driver." A new threat emerges when an unexpected figure, once admired by all, returns to Roush's village with the intent to reach Heaven's Door. This adversary is not Diablo or another demon. After his village is destroyed and his sister taken, Roush must assemble a team to confront this new danger.
