Hell, if we're going by the argument of "Yozakura is a comedy, you're being unfair by comparing it to battle manga", Saiki is a just as valid a demonstration. The first 20 chapters gradually spoonfeeds characters, first establishing Saiki and his parents, then one by one introducing Nendou, Kaidou, Terahashi, Yumehara, Hairo and Toritsuka one after another. The result is that readers slowly get introduced one by one to the characters in Asou's initial plans for the series and how they relate to Saiki himself. This creates a sense of stability since it gets readers used to the set-up and leads people to be interested when Asou expands on both the cast and their dynamics.
Yozakura, meanwhile, introduces eight characters in its first chapter, then does virtually nothing with half of them until Chapter 10. By that point, the series is suddenly introducing even more characters, even though none of the ones it already has feel fully established. It doesn't help that virtually none of the characters interact with anyone aside from the main duo, meaning they feel even more isolated and meaningless.
