One Room, Hiatari Futsuu, Tenshi-tsuki.

One Room, Hiatari Futsuu, Tenshi-tsuki, authored by the mangaka matoba, began serialization in Square Enix’s Monthly Shonen Gangan in 2022. The series centers on the life of high school student Taro Tokumitsu, whose solitary existence is transformed when a literal angel descends to live with him in his modest apartment. The work fits into a lineage of 'cohabitation comedy' manga, focusing on lighthearted domestic interactions and the gradual development of interpersonal bonds.

Matoba’s artistic approach emphasizes expressive character designs and a warm, inviting visual tone that complements the series’ slice-of-life pacing. By stripping away traditional fantasy epic tropes in favor of mundane setting constraints, the narrative highlights the charm of daily routine juxtaposed with the surreal nature of its protagonist. Upon its release, the manga was noted for its clean panel layouts and gentle humor, leading to an anime adaptation that further expanded the reach of the original print volumes.
