悪樓の島

舞台は本州から遠く離れた太平洋に浮かぶ離島、青野久島。The setting is Aonokushima, a remote island in the Pacific Ocean far from Honshu. There, Reigo Murasame, a high school student, lives alone. His parents died in an accident, and his grandmother, who took him in on the island, also recently passed away. Still, he has no intention of leaving the island. Because he has someone he has feelings for, Ichika Kannagi. One summer day, the two of them decide to go to a summer festival. When they learn that there is a secret festival that is held only by adults, they go deep into the mountain where entry is prohibited. Unbeknownst to me, that was the beginning of a tragedy.
