Is there a source for the arranger credit to "Mitsuhiro Yokota"? As far as I can tell, this person is not a part of the unit at least.
EDIT: Never mind. Helps to look on sites other than Japanese ones
EDIT 2: However, when taking a look at the actual
game credits, it seems the credit is not really for arranging it, but rather for A&R, so I'll change it.
