Rise of the Dragon
Shosuro Heisuke's daughter
Despite Shosuro Heisuke and Agasha Minami agreeing to raise Reiko as a Dragon, Reiko is fascinated with her father’s culture and prefers to use her father’s family name. Whenever she can get away with it, she wears a dragon-themed mask – she believes it makes her look mysterious. She has also learned a degree of subtlety (probably from playing with Kaoru), and will sometimes improvise a mask with a scarf.
Reiko spends most of her time with Kaoru and looks up to her as a big sister. As a result, Reiko is particularly insensitive to differences in social status.
