This song is from the anime Rozen Maiden — Season 1 episode 12 to be exact. Right after the opening theme the hype immediately kicks in. Long story short this anime is about dolls trying to kill each other. It’s been a while since I seen it so I don’t remember much but what I do remember is SuiginTou, the main villain of season 1, makes this anime worth watching. After watching this anime she’ll convince you the word “junk” is a cuss word. I can’t explain it. Just make sure to watch the Japanese sub. It’s amazing.
