One-Punch Man OVA

One-Punch Man OVA is a series of six original video animation specials released during winter 2015, featuring stories created directly by the series' original mangaka, ONE. These episodes were included across the DVD and Blu-ray volumes of the anime and offer an alternative viewing experience to the main series, focusing on original narratives rather than adapted manga material. The OVA format allows for self-contained stories that explore different characters and scenarios within the One-Punch Man universe.

The first special, "Shinobiyori-sugiru Kage," takes place after Saitama's encounter with Mosquito Girl and follows Genos as he attempts to uncover the secret behind Saitama's overwhelming power. The story introduces a mysterious character who harbors a grudge against the protagonist. The subsequent specials continue exploring various character dynamics and mysteries, with titles suggesting themes involving ninjas, martial arts masters, and unexpected crimes throughout the collection.

Since the OVA has finished airing, all six episodes are now available for viewing. Fans of the main series will appreciate these original stories that provide additional depth to characters and expand the world beyond the television adaptation, while newcomers can enjoy standalone action and comedy without requiring extensive prior knowledge of the broader narrative.
