Yayoi

In the land of nature, there are giant creatures such as forests where large trees grow, wild boars, bears, wolves, deer, and giant rats, and the animals are protected by the 'Forest Keepers'. There are beautiful rivers and springs everywhere in the forest, which are a place of rest for the animals. The forest is the home of the beasts. The forest, which nurtures lush vegetation and large trees of considerable age, is overgrown as it was in the ancient past. It is a world where humans and animals are in conflict, but insects and humans were also in conflict. Unlike modern insects, the ancient insects are not weak beings that are only killed by humans. They have knowledge similar to humans and have bodies specialized for hunting humans. Some insects even begin to take on the appearance of humans. Humans cannot tell by appearance. They seduce and deceive, threatening people's lives. Evolved insects love human flesh. The forest is guarded by Garmrein, who is the size of a small mountain, as the 'Forest Keeper'.
