Tremux | LoLK Hecatia's Theme: Pandemonic Planet @Tremux1 | Uploaded August 2015 | Updated October 2024, 14 hours ago.
This is Hecatia Lapislazuli's theme from Touhou 15: Legacy of Lunatic Kingdom

I used Junko's picture because she is too involved in the fight.

I like this theme a lot because it truly brings the havoc and chaos to life, also Illuminati confirmed with those triangles
