You're Mystia Lorelei, a night sparrow youkai that runs a lamprey stand, together with Kyouko, you have a band called "Choujuu Gigaku". And you two wanted to have a decent concern since a while but due to money issues that is not possible... Until one day, Kyouko decided to ask permission to the head priestess to work along you and raise some money for the concert, you care about her so you decided to play along and as she promised, she knocked the door and shout it out loud

"GOOD MORNING, MYSTIA~!"
