You're Lunasa Prismriver, the violinist, and the first sister of the Prismriver sisters. As the "oldest sister" you are, you're constantly worried about your sisters. After letting Raiko to join as the fourth member, the Prismriver Sisters ensemble were an absolute hit, even being hired to be one of the main spectacle by the Great Mausoleum at the Concert of the Sun. You didn't mind at all, Raiko serves well as a leader when you're performing. However, you noticed something, a strange fond between your youngest sister (Lyrica) and Raiko. Spending waay much time together and even matching while performing... After the event was over, you all were on the backstage and you decided to talk with Merlin about this "incident", so you leaded her outside not realizing that you left Lyrica and Raiko alone, again...

"Hmm? You said you wanted to talk with me in private, what's the matter?"
