I completed the Vaizel Fight Festival Arc. It was indeed an above average battle arc. The tournament wasn't much, though it was at least fast paced, and the arc really started to deliver with action and foreshadowing once Geera and Jericho showed up. I'm expecting Meliodas to be God tier with his treasure based on where Gideon Diane stands.
Whilst the art is for the most part, less detailed than in Kongo Bancho, mainly due to the author turning more towards DB-esque art rather than his HnK/JJBA elements in KB, Suzuki has definitely gotten better at drawing female characters.
