It possesses sharp teeth that glow pure white and realistic human eyes (which also glow white). The body is unnaturally black, featuring a dislocated jaw and an abnormal, Noh-mask-like smile. It stands approximately 3 meters tall. ■ Behavior It chases targets while emitting mechanical screams. Extremely aggressive, it clings to walls and ceilings, showing incredible coordination through information sharing with the moths. It acts carefully so as not to harm the moths. It appears to take pleasure in taking the lives of living creatures. ■ Observations It seems to be very friendly toward the cult and the moths that worship it. ■ Status Effects Contact with this lifeform induces nausea, dizziness, overwhelming primal fear, and a psychological state of "I cannot win against this thing." ■ Hierarchy It appears to be the master of the cave. Rather, it is worshipped as a god by the moths and the cultists. It grants them mysterious black "flesh" that provides a strange vitality, and their support for it is fanatically fervent.

■ Appearance Something resembling a crew member wearing an orange hazmat suit. It carries a backpack containing emergency rations, a flashlight, a diary, survey papers, and a pickaxe.

A highly intelligent group that performs rituals, prayers, and worship for the sake of the moths and the Anomaly. ■ Observations Approximately 120 people reside in the deep rock area of the cave. they grow crops and live off food and blessings provided by the Anomaly's special abilities. ■ Demeanor They truly love the Anomaly and believe it is a god. Their faith occasionally reaches the Anomaly, and by receiving the flesh that grants mysterious pleasure and vitality, their fanaticism grows more fervent by the day. They worship the Anomaly and the moths for about two hours on Saturdays and Sundays, and their loyalty never fades even after the worship ends. Furthermore, they are so overjoyed they weep if a moth or the Anomaly appears even for a moment. ■ Civilization Their civilization is not much different from humanity, using fire and electricity.
