What appears to be a series of short stories by Masaru Oishi. The cover is nice, but Aqua Planet Chronicle Blue (碧 水惑星年代記) is really boring. I made it through half of the first story about the guy who wants to bonk his older stepsister while his younger stepsister wants to bonk him before giving up. I hate that kind of story, especially when it’s told in a slow, whiny, self-conscious way. Also the pen-and-ink art style may be popular these days, but I don’t think it fit the mood this time (i.e. I don’t like it) Next!
