It's been pretty good so far (through 6 episodes) with lots of action, but a lot of world building as well. There is a childhood friend there for the first few episodes (obviously deep feelings as well), but then the setting changes, so she is not present. I'm sure she will come back into play later, but looking at future images, I don't see her anywhere. It is a shame they are middle school aged though, but we'll see, the new girls the boy is with, is your classic blond tsundere, and a pick haired manga/anime girl, and a few other characters, but there has been no character developement for them as of yet... We'll see once I dig deeper into it.
