This highly acclaimed mystery tale about a young man teaming up with a handsome jewelry appraiser inspired a popular anime–and a manga adaptation (also from Seven Seas)! Richard Ranasinghe de Vulpian is a brilliant and enigmatic British jewelry appraiser. Seigi Nakata is a young college student. Their worlds are as different as can be, but when a chance encounter leads Seigi to hire Richard to appraise a family heirloom, it sparks a partnership that goes well beyond that one job. Together, the duo investigate jewelry-related cases and solve mysteries, finding the secret messages hidden in the hearts of precious stones–and the hearts of those who possess them.

IN SEARCH OF THE PERFECT MATCH Seigi, an ordinary university student, works at a jewelry shop run by the decidedly not-ordinary Richard. One day, a young boy named Hajime walks in, takes out a small cat’s eye gemstone, and asks Richard for a matching stone. What story lies behind this particular request?

In the future, robots are more than machines. Autonomous "cyber-persons" with A.I. brains are part of society, interacting with humans while developing their own culture. In fact, they may be surpassing humans, as biological homo sapiens have begun to die out and give way to robo sapiens. But are humans truly disappearing, or are robots the newest form of humanity? This millennia-spanning, speculative science fiction manga of interconnected stories, both human and robotic, was awarded the Division Grand Prize at the 2020 Japan Media Arts Festival.
