高橋留美子 人魚シリーズ [Rumiko Takahashi Ningyo Shirīzu]
High schooler Yuta and his friend Mana confront the dark side of immortality in Rumiko Takahashi's haunting Mermaid Saga, a chilling fantasy-horror series from Shogakukan that began in 2003. Across three issues, the duo's search for a cure to Yuta's centuries-old curse—inflicted by eating mermaid flesh—leads them into encounters with other immortals and the monstrous consequences of the mermaid's power. Takahashi, best known for Urusei Yatsura and Ranma ½, brings her signature wit and emotional depth to this eerie, introspective tale, which stands as a mature, atmospheric departure from her comedic works. Its exploration of loneliness and the price of eternal life makes it a quietly essential read for fans of thoughtful supernatural storytelling.
