The Long Night Is Coming to an End

Known as a detective in the night city, I went on a business trip to an island to investigate a serial murder case. Whether by misfortune or luck, another deceased person appeared the night before my arrival. Relying on my unique ability, I extracted enough information from the mutilated corpses and easily caught the murderer who was about to commit the crime. But just when I thought that was the end of it, another victim appears! The whole case became full of doubts. I never thought I would see them here. The dark past is rushing towards me like a tide, trying to drown my reason... Mental patients with incomplete humanity, sick buildings wriggling like maggots, siren larvae parasitic on the human body, siren singing voices that cannot escape... I have no choice but to fight to the death!
