Sayoko is a young woman overwhelmed by intense paranoia, convinced she is constantly watched. This debilitating fear forced her withdrawal from school. Seeking escape, she joined her friend Noriko on a mountain hike. They became lost and stumbled upon an isolated monastery practicing an esoteric form of Buddhism centered on self-suppression. Vulnerable and desperate for refuge, Sayoko chose to stay despite Noriko's objections. The monks pursued extreme asceticism, starving themselves in preparation for "eternal meditation," a ritual transforming them into living mummies.
Noriko and another visitor, Aya Kuramoto, uncovered the monastery's dark truths. Following monks into a forest, they found a vast underground labyrinth beneath a giant Buddha statue. This maze served as the tomb for the mummified monks, their preserved bodies embedded within its walls. Trapped inside with Noriko and Aya, Sayoko navigated the claustrophobic, corpse-lined passages under extreme physical and psychological strain. Aya separated from the group upon discovering her brother's mummified remains.
As Sayoko and Noriko pressed on, they encountered increasingly fresh corpses, culminating in sections where monks remained barely alive yet immobile within the walls. Surrounded by these living mummies, whose eyes tracked their movements, Sayoko's fragile psyche shattered. Overwhelmed by terror, guilt over abandoning Aya, and the relentless staring eyes she had always feared, she screamed at the monks to stop looking at her before collapsing from exhaustion and complete psychological breakdown within the labyrinth.
