Gintama: Monster Strike-hen

Gintama: Monster Strike-hen is a two-episode online anime collaboration that aired in summer 2019. This action-comedy crossover brings together the irreverent world of Gintama with the mobile game Monster Strike, blending the series' signature humor and fantasy elements into a brief but focused experience. The ONA format allowed for a self-contained story that didn't require integration into the main Gintama timeline.

Released on August 29, 2019, this project represents a standalone venture for the franchise. Its modest episode count makes it ideal for viewers seeking quick entertainment without a major time commitment, whether you're a longtime Gintama fan curious about how the crossover plays out or someone looking for a compact action-comedy that doesn't demand extensive prior knowledge. The finished status means all episodes are immediately available for viewing.
