月嶋 成美

Tsukishima Narumi is the manager of the antique shop "Secundum" and Narumi Kyouka's childhood friend. Kyousuke agrees to help her out at the antique shop in exchange for Narumi's help in getting information about the pendant he is looking for.

Narumi is a beautiful woman, but she has a selfish and arrogant queen-like personality. She doesn't like bright lights and always keeps her store in a dim environment, therefore she gives off the impression of a vampire. Interestingly enough, she owns a black cat named Hellsing.
