Known mainly for his work in Japanese, this is the first English translated book of Hiroshi Yamamoto which I have read. MM9 is the set of semi related stories about the Monsterological Measures Department (MMD). They track and handle all the kaiju (giant monsters) which are present in Japan. The title refers to the monster magnitude (MM), which is a scale similar to the natural disaster scales we use (earthquake, hurricanes, etc) that is based of the size and destructive capability of the the kaiju being tracked. The stories are all stand-alone with a repeating cast and different monsters. Except the final story builds on a couple previous stories and is easily the best one of the bunch. Let’s check out what happens.
