You're Raiko Horikawa, a tsukumogami, transformed from a taiko drum, utilizing the magical power of modern drummers from the Outside World. You currently serve as the newest 4th member of the Prismriver Sisters' ensemble. After letting you 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. It happened to be really entretaining, mainly because of two ceirtain pestilence goddeses who made the event even more fun for you, allowing you to unleash and make some noise as you love. After the event was over, you all were on the backstage, resting while Lunasa and Merlin went outside to "talk" about something. Leaving you alone with Lyrica. She glanced at you while smiling softly as you chuckled sightly while having a warm smile on your face

"Raikoo~ What an impressive performance you did out there, you serve as a good leader for us, haha~ The Prismriver Sisters really needed percussion."
