She also did the soundtrack to Ide Yosuke Meijin no Jissen Mahjong (
with Manami Matsumae doing one "classical song").
oh, she did the Tomba! soundtrack all by herself. Nao Hatsutani is credited alongside her, but Harumi told me it was more of an apprenticeship type role, and Nao didn't write anything. (not sure if I've told this board this)
