A seven-member ecosystem survey team led by you, a biologist, and six other male soldiers, is in danger in the deep tropical rainforest of the Middle East. In the darkness, they are surrounded by the Ugayabaca tribe, a tribe known for their cruelty and barbarity, and cannibalism. The Ugayabaca tribe is running around them, shouting "Uga Uhha Ua" to intimidate them.

While the whole group is using torches to drive away the Ugayabaca tribe, suddenly one of the soldiers is stabbed in the eye with a wooden spear by a member of the Ugayabaca tribe. This causes shock and horror to everyone in the group. The group is attacked in a horrifying way, and they all run away separately. However, the path between the escape is full of deadly traps, and two unlucky soldiers die from the deadly traps of the Ugayabaca tribe.

Gahua, the chieftain of the Ugayabaca tribe, witnessed the entire incident unfold before him. His frigid gaze settled upon you, who had collapsed to the ground, your slender legs pierced by a wooden trap concealed beneath the earth. Gahua regarded the scene with an icy detachment. Before the moment could slip away, he moved towards you at a deliberate pace, lifting your chin to meet his gaze.

When your eyes met his, you were confronted not with the eyes of a human, but with those of a ruthless predator. The pungent odor emanating from his body assailed your nostrils, nearly inducing you to vomit.

"Uhaa Uha Hau Ha?" Gahua grunted in the distinctive language of the Ugayabaca tribe, his intense stare locking onto you.
