Theatre of Darkness: Yamishibai (2013)

S06E13 Echoes

As Eriko and Shiho ascend the mountain, Shiho revels in the thrill of her voice bouncing off the cliffs, while Eriko seeks a moment of tranquility to appreciate the stunning scenery. Suddenly, a man's voice pierces the serene atmosphere, and the echoes that once felt playful now stir an unsettling sense of dread in Eriko and Shiho.
