Sometime after Wataru Ikusabe's adventure and victory against Doakudar, a new demon overlord named Ankokudar besieges his reign on Mt. Soukai by stealing all the consciences of every citizen and enslaving the strong negative ones to his loyal army. To ensure nothing will stand in his way, Ankokudar personally enters the Genseikai realm to steal Wataru's conscience, resulting in the boy becoming bad as well as losing his previous memories and experience as the savior.
Wataru's delinquent style is abruptly halted by Shibaraku and Himiko, who free him of his "corrupted" influence and bring him back to Shinbukai. After a while, upon defending Monjara Village with Ryujinmaru, Wataru regains his lost memories and must venture as the savior once again with old and new friends to liberate Mt. Soukai from Ankokudar's terror and reclaim an important piece of his heart.
