BEFORE YOU CAN READ THE CHAPTERS

since "Ib"(which is Created by Kouri) and Rhythm Heaven(Which is also created by Nintendo and Ko Takeuchi) is my favorite, I had to combine them into one!
But in this fanfic, My OC Michael Nijiiro is portaying as Ib!

Ib is owned by Kouri
Rhythm Heaven is owned by Nintendo and Ko Takeuchi
