How Long Does It Take to Watch Dark Gathering?

After a devastating encounter with a restless spirit, ghost-fearing psychic Keitarou Gentouga became a shut-in to avoid additional spectral catastrophes. But no man is a haunted island, and Keitarou eventually reintegrates with society by getting a part-time job as a tutor to the child prodigy Yayoi Houzuki. Yayoi isn’t just an academic genius, though. She’s a talented psychic medium hell-bent on finding the malevolent spirit behind her mother’s disappearance, and she’s gravely determined to drag Keitarou into her terrifying world of grotesque supernatural phenomenon.
