Ikusa Megami 2 ~Ushinawareshi Kioku e no Chinkonka~

Celica has finished his mission of finding Princess Latina in the Kadora Mines around the town of Milphe, where he accidentally bought Saria, a slave girl, and made her his forth Apostle. Six months later, in his mansion in Rewinia, he was awakened by a strange sound of ringing bells, which no one else had heard. This day he had an audience with Water Miko, who sent him on the another task - a research group from Rewinia went missing while performing a scheduled work in the dungeon where one of the legendary Seven Majins was sealed. Celica could not imagine that this simple mission is just the first step that eventually will lead him to his forgotten memories and make him face his past.
