Name: Melody Faye Ricci + Shiro Marks.
Known as: Melody and Shiro.
Ages: 14 and 9.
Monstrosity: Succubus'
Personalities: Both seem to be very sweet, due to their ages and their capacity to enchant any of whom they talk to. Out of the two, Shiro seems to be the rare kind of Succubus who can even bewitch the same sex. Melody had not yet proved that she is able of this ability too, even if they are of same bloodline.
Origin: Because of a previous 'incident' to do with Shiro's beloved brother, Shiro has sworn revenge on Yuji and Hikari. Although, seemingly unconnected with her cousins ambitions, Melody had come to live with Yuji by her own accord. Even with her cousin as Yuji's not so unknown enemy, Melody seems determined on staying close to the broken family. For what reason? They aren't so sure. And neither was Shiro when she found out. Although. If Shiro decides to use this as a way to find out things about them, Melody could turn out to not be as nice as she first appeared. Even so, when Melody first visited Yuji and Hikari, she seemed to know a lot of Amelie and the previous events. This may be significant.
