帯刀 怜

The secretary to the Mikado clan, Rei is also responsible for Ririka's home schooling and the management of the household servants. She is absolutely loyal to the Mikado household and will execute any command given by the clan heads without question.

 Originally an orphan from beyond Japanese shores, she was bought by Heizo when he chanced upon her on a business trip and brought to Japan as his possession. Her name is the one she adopts after being bought by Heizo. She is also well-versed in medicine and is responsible for concocting the unguents  ingested by Heizo and Fumika as well as improving their efficacy through use of freshly procured body parts from kidnapped children. Her loyalty is to Heizo alone despite her pact with Maruyama during the rite; she obeys Fumika's instructions and serves her faithfully as a secretary but is well aware Fumika is little more than a puppet under Heizo's domination.

She derives pleasure when treated as an object rather than a human and cannot be sexually aroused unless she is denigrated and abused by sexual partners. Rei is quite happy to engage in orgies with the male household staff after berating them in the daytime as a way to "release stress". Her sole hobby is collecting more knowledge to create more potent aphrodisiacs and unguents, which is her main motive for working in concert with Maruyama without Heizo's knowledge (although she has no intention of betraying Heizo). /
