Tanya's theme in the series, overall one of my favorite villain themes in anime.

Young Girl's War (Saga Of Tanya The Evil) - Saga Of Tanya The Evil OST

I"m really into this song currently, It's from Honkai Impact 3 a game by MiHoYo.
I realized there isn't one here on SoundCloud so I decided to upload it.
It's really a good shit, Trust me.
