DESCRIPTION:
This is Utsuho "Okuu" Reiuji's theme from Touhou 11: Subterranean Animism

I love this theme. It's so, overpowering. I usually don't like things that make me feel small and insignificant, but this is probably one of those rare exceptions. I think ZUN should've added the sirens to the theme, instead of when she did the spells. But, who am I to argue?

Utsuho is the only Touhou final boss with an incident with a properly evil purpose. I mean:

Remilia- blotting out the sun with scarlet mist so she can take a walk
Yuyuko- stealing spring so she can figure out whats under the tree in her garden
Suika- throwing parties everyday to draw out the oni
Eirin- cutting off Earths connecting to the moon to keep from being discovered and taken back
Komachi- just couldn't be bothered to get off her arse and do some work
Kanako- Shut down the Hakurei shrine to keep all the faith for herself
Tenshi- Cause a massive earthquake because she was bored
Utsuho- Take over Gensokyo and burn it to a cinder.

I mean c'mon, when has burning things and ruining life as we know it not been evil?
