At first blush, this looks to be your typical "Natsuyasumi" show. But, there's a hook, of course, and with that comes some mystery, some drama, and the foundation for what could be an enchanting story. And it's all wrapped up in a nice package, with an adorable lead, a laid-back pace, and solid direction. Good vibes all around.
I was a little surprised with the fanservice, however, subtle as it may have been. For some reason, I was expecting the show to be more geared toward a female audience. It definitely feels like it otherwise. Then again, given Gotoh Keiji's past work, I probably shouldn't be surprised. That's not a complaint - just an observation.
Anyway, the artwork is nice (lots of detailed city backgrounds!), the character designs are cute, and the music fits the mood perfectly. The OP and ED are both superb. I'm looking forward to the singles.
