Kind of, it was a slice of life until episode 7, then they finally got around to adding some plot in. The MC actually has chuunibyou, but doesn't at the same time, since he does have superpowers. It's not amazing or anything, but its better than your average anime with a club.
Hm... well, a few of the characters have chuunibyou, but one isn't revealed until later, similar to Chuunibyou demo Koi ga Shitai. They are also in a club as well. I would say the only real difference is that they do have superpowers, and the MCs of this anime are more cookie cutter than Chuunibyou demo Koi ga Shitai.
