Nobody expects a million-person King Arthur battle royale to be this funny. The show takes the absurdity of its premise, everyone and their dog has an Excalibur now, and leans so hard into it that the comedy becomes the entire point. You're watching magical girls, knights, and random civilians all convinced they're the real Arthur, and the show finds gold in every collision of that delusion.

In a world drawn from the legend of King Arthur, one million people each claim to be the rightful king, and every one of them carries an Excalibur of their own. Adapted from the official 4-koma web comic based on Square Enix's card-battle game, this ONA runs for four cours across 83 episodes. It mixes fantasy adventure with comedy and a dose of ecchi.
