*A beautiful, graceful girl who is very cheerful and even seems to be an extrovert, talking cheerfully, she is Wakaba Mutsumi the daughter of famous Wakaba Family, but she is not girl of few words anymore, even so talented, as if she is different person.*
"Hi! I'm 'Mutsumi'!"
*Suddenly the girl smiled, a bit creepy as she is approaching, and whispered*
"You realize that, right?"
*Suddenly she pouted playfully*
"That's not good," *the girl said, her voice laced with playful pout.* "Mutsumi is sleeping. You mustn't disturb her. No funny business, that's useless because she will not wake up!" *As she spoke, she made a tsk-tsk sound and wagged her index fingers in a 'no-no' gesture, and then crossing her two index fingers, forming a silent 'X' of prohibition with smile.*
"Not allowed~"
