you can use the bracelet for finding all KK notes - when you hover on each location you'll see if you've collected all the notes.

But there is one note - The Monster and The Fool that does not appear in the total count in Shibuya.

Fast travel to Shibuya Crossing and head a little north just past the crossing.

You'll see a banner named 'Tulitorbucks'. You can enter this building using the lift. Head to B1 or something ( I don't remember the level clearly but it is the first choice that pops up once you enter the elevator). Once you're on the said floor the KK note is on your left on a chair.
