We all know that a lot of the booty of the golden age of explorations made it into museums. The British Museum in the C.M.B. story, which had custody of the recondite scientific curiosities and artefacts collected by explorer/adventurers and stored in a Wunderkammer, decided to study the dusty arcana in the 19th century. Three investigators dubbed the "Magi" were appointed to do the research, each given a ring embossed with the letters C.M.B.
Fast-forward to present-day Japan where Sakaki Shinra is the curator of a museum of oddities. He now has possession of the C.M.B. rings, indicating that he has been granted the status of guardian of knowledge like the Magi that preceded him.
- Action Girl: Nanase, who with Kana can thrash the whole squad of desert raiders empty-handedly.
- Catch Phrase: "Welcome to Wunderkammer."
- Chaotic Neutral: Mou, the Black Broker.
- Cheerful Child: Shinra
- Cloudcuckoolander: Shinra
- Equivalent Exchange: Shinra only willing to help if you promised him something, since his service as CMB Magi is highly regarded and accurate. Even Nanase found this kid a tough kid to crack, although promising him something mundane but interesting is quite fine.
- Friend to All Living Things: Shinra
- Has Three Daddies: All daddies are CMB Magis's, to boot.
- Intelligence Equals Isolation: Shinra never went to school, and it was Nanase's dad who got him into one.
- MacGuffin: CMB ring, with one you can get almost infinity funding for any research. Then it's hinted that this might be why the Magi choose Shinra as their successor, they don't want the ring falls into the wrong hands.
- Mishmash Museum: Well, Shinra is the curator
StupidityYamato Nadeshiko: Since Nanase took school in a very prestigious school, she bound to do this, while she's actually full blown Action Girl at heart.
- Rags to Riches: Nanase's parents backstory; his dad, a commoner, ended up with her mom, a heir of multinational company, whose dad only allowed if their daughter (Nanase) is get schooled at certain school.
- Wise Beyond Their Years: Shinra, again.
