We get to see more of Luck's backstory in this volume and actually see him fight and there's a lot he hides behind that smile of his. He seems to still be adjusting to the idea that he's not alone in the world and has Asta's same sense of needing to prove himself. I'm looking forward to seeing him continue to allow his friendships with the rest of the Black Bulls grow. Yuno and Asta's friendship is still my favorite. They're more like brothers than friends, actually, and have one of the healthiest rivalries I've seen in a while. They both push each other to do better and before any kind of rivalry between them there is respect and friendship there. I'm excited to see this fight go down next volume. I also really like the Wizard King and can't wait until Asta gets to know him more. I'm sure that's coming up later on in the story. This just gets better and better!
