カレンデュラ・オフィシナリス

She came to Japan from Racronia to be married to Shuuma. Calen is the 100th daughter in the Officinalis family, one of the three big households. Her marriage to Shuuma is arranged and thus for her, love is a low priority.

Calen was raised in the vampire society, and for this reason she can never understand why Shuuma doesn't try to drink from human beings. She is mature as a vampire, so she can control her impulse to feed.

When Calen first came to Japan, her naiveté was exposed because she wasn't aware of the differences between vampires and humans. Now after making a friend named Sakurako, she is enjoying her life.
