Richard Ranashinha de Vulpian/Relationships

Seigi Nakata
He is rescued by this university student from a group of drunkards one night. Together they begin to solve mysteries surrounding the jewels they come across as well as their owners.

Shaul Ranashinha
Shaul found Richard when he was suspected for scamming a German couple with a blue zircon gem. Shaul Ranashinha reprimanded him as a Jeweler for selling something a customer does not want under the pretense that it is something else, and tells Richard that he has a proposal for him. Richard regards him as his master.

Miyashita Family
He has been an acquaintance of Tae's family for many years. Both Tae Miyashita and Kimiko Miyashita recognizes him at first sight, even before the Seigi's case.

Homura Family
He made a connection with Homura's family after Takashi's entire case. He met up with the former once more since then. Since his family is a greatly ambitious jewelry collector, he made an arrangement to show Homura more the next time they meet. He will like Richard to show him if the latter has any good stones, nothing other than that.
