A young laddy is summoned to another world to be The Hero, fight their wars, and ensure the kingdom that summoned him comes out on top. He's given a legendary heirloom ring that enables him to use magic and give him a bit of a leg up on the competition. He's strong, but the rank and file soldiers of his nation are weak shit. To make matters worse, there's been recent rumors of calamitous spiritual unrest… Will our hero manage to save the day, calm the rage of the gods, and make it back home? Just kidding, everyone is kemonopeople, mostly cute girls, and genuine war was abolished years and years ago. Now, nations compete in mock "wars," which are more akin to hardcore triathlons, events, and other silly games. Everyone is friends with each other, nobody is seriously hurt, and even when at "war, win or lose, everyone goes home happy and all smiles.
I recently came to the realization that the setting is pretty much Gensoukyo. Tons of cute girls, hardcore 'battles' taking place with deep stakes on the line, but at the end of the day everyone is happy and all is resolved peacefully. It's pure comfy, with a nearly limitless setting that you can just dump onto endlessly. Season 4 when?
