The continuation of the Q.E.D. series under Shounen Magazine R.

A jungle and war victims: these fragments constitute Yo Mizunashi's leftover memories. A doctor's son, Yo questions whether these pieces of his "past" aren't just constructs of a delusional mind. He forces himself to remember and in seeking his personal truth, alienates himself from his peers and presents school bullies with an easy target.

One day, while he is being harassed, a mysterious man—with a gaping wound on his abdomen—appears before Yo and his tormentors. Yo hastens to help the stranger and in return, learns that his unexpected patient goes simply by the name "R" and that R trades in secrets.

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.

Touma Sou graduated from MIT, but he comes back to Japan because he wants to know how it feels to be a high school student. On the other hand, Mizuhara Kana is a strong girl who loves sports. Together, they are partners in solving cases that happen around them.

Won the 33rd Kodansha Manga Award for shounen in 2009 (shared with Fairy Tail).
