シガテラ [Shigatera]

A taut six-issue thriller from Kōdansha (2003–2005), Shigatera follows a young man who inherits a mysterious and dangerous power tied to a toxic, hallucinogenic mushroom. The series, written and illustrated by the acclaimed manga creator Satoshi Shindō, builds a claustrophobic atmosphere of paranoia and ecological dread as its protagonist navigates a world where nature itself can weaponize. Its concise, focused narrative and striking visual storytelling make it a memorable entry in early-2000s psychological horror manga.
