Description

It was the forbidden summer.

Gojou Kouichi is returning to his hometown island. His little sister who came to welcome him at the harbor, his parents’ guesthouse and the state of the town all appear to be unchanged. However, strange creatures have been appearing on the island. Every nightfall, a lone girl has been tasked to destroy these abnormalities and warn the villagers. One night, a doubtful Kouichi was assaulted by a monster. The girl, Inui Komako, saves him from the clutches of death with blade in hand. Kouichi was certain that he saw it. He saw the monster appearing from obscurity, but also the realm spreading out from the ends of darkness. It was a sight that humans must never lay eyes on.

The forbidden domain.
