The Music is in Me

While investigating another one of her dreams, Yumi and Paris find a rather large music box... In an abandoned warehouse?

Upon opening it, Yumi discovers the singer from within the box- a doll-like woman named Kitsune, who happens to have the same creator as Paris. Thankfully though, she's very benevolent, and proves to be very useful!

...Still, though, despite the eighty or so years that had passed, Kitsune and Paris still find themselves butting heads.
