It's a 4-koma style comedy based on the Girls und Panzer anime series. For anyone that thought that the anime didn't have enough comedic or slice of life scenes, this series, albeit in a over-the top fashion, does exactly that. It's not canon either, but the series is still a fun read. There's such a large cast of characters in this series that creating different scenarios and chapters is an easy feat. That being said, the series definitely has a host of unfunny chapters so it's hit or miss, but ultimately, that's up for you to decide. Overall, only read if you liked Girls undPanzer to begin with.
