I'm a librarian who loves anime, manga, and reading a wide variety of genres.
The second volume is crammed just as full of events and world and character info as the first. The one part with the young illegal contractor was over so fast that, if you blinked, you missed it, which makes me wonder why Mochizuki even bothered. If the point was to show that illegal contractors were not necessarily evil people right from the start, then it might have been better to incorporate that into the illegal contractor story that starts in the next volume.
Two things I liked: Gil and Oz's friendship, and Break. A portion of this volume expanded upon Gil and Oz's first meeting, Gil becoming Oz's valet, and the two of them renewing their friendship after Oz learns that Raven is Gil. It was all very sweet. Break looks potentially villainous at this point in the series. He can go from smiling and silly to sharp and a little scary in a second.
