The Seven Deadly Sins: Four Knights of the Apocalypse 20

Percival and his friends have journeyed into Camelot to stop King Arthur once and R for all, and with Gawain's help, they reach the Cauldron of Annwfyn. There, they manage to find Tristan with ease-but he doesn't remember them, and reacts to their warm welcome so coldly that they almost doubt he's the prince they knew. While taken aback by this turn of events, they still manage to secure spots in the top-16 bracket of the Gladiatorial Festival-and, much to their surprise and delight, so do Isolde and Chion. The first one-on-one matches of the tournament begin: can one of our heroes make it all the way to the top of the ladder and claim an opportunity to take down Beltreipe?!
