A Hero of Old

The first hero of Japan valiantly fought the Demon Lord that sought to take over the world. Though on the verge of death, the Demon King cursed the hero to be frozen in time until he finds his soul mate.

Nearly 3000 years later, and a group of girls are dragging their friend to take a photo with this statue in the middle of the forest they are using for their training camp. When one of the girls stepped up to have their photo taken with the statue, the statue suddenly burst into light, and in its place was a green haired knight.
