Phantasm Boss - Yukari Yakumo's theme
"Meant to be an arranged version of Ran's theme, it ended up quite different. This one has an ominous feeling. Or rather, she's the very embodiment of ominous. Even compared with the past characters, she has a devious appearance, a dubious character and thoughtless barrages. The theme's just like her."
Now someone from 2a03.org did another cover of this song in a variant of YM2413, but since that sound chip sucks (as it does in FamiTracker, no difference), it did not do the square leads justice at all. About two minutes in the change in instrumentation was only there to pretend they span over two octaves.
