TenAka is a 3 volume isekai-parody Yuru Yuri spin-off. The art is great. The comedy isn't quite as good as the main Yuru Yuri series IMO, but is still decent. And the characters are fun as always. There's two main problems with the manga though. First is that there are already so many isekai parodies out there that it is hard for one like this to compete. I'd solidly recommend TenAka to Yuru Yuri fans (such as myself), but for isekai fans there's nothing here you can't get elsewhere. Second problem is that it unfortunately got axed. The plan was apparently to do arcs parodying various popularisekai series, and to give each of the characters some focus, but as it is we ended up with a rushed conclusion just as the manga was finding its groove. There was definitely some promise here, but it got cut short.
