Amara: The Priestess of Makoto

Five thousand years ago, swarms of demons and monsters emerged from the deepest layer of the earth to the ground. The hideous creatures that appeared to be myths showed themselves and wrecked havoc. They were believed to have been awakened during this era, the feudal era for one reason: to acquire the forbidden fruit that was blessed by the heavens on the maiden shrine in the village. The forbidden fruit was believed to grant someone an eternal life with powers that go beyond strength. Thus it was hidden by the first maiden shrine and was locked away, out of the demon's reach. The first maiden shrine became a legend for she was the one who sealed those creatures in the first place and now that her legacy was passed on, the seal weakened and does awakened the demons.
