Okay so recently I remembered a Miku song titled "CRAZY", it is not "Crazy Night" or anything similar to that, I can say that with full confidence. (Google has been less than helpful in my search.) It's a yandere song with an animation that doesn't even include Miku.
I have found the song up on youtube with an English sub before, but after doing another search more recently, the only thing that comes up is an Espanol sub video, this is great for listening, but it's tough when I didn't listen to the song that much so I don't remember the lyrics.
The vid doesn't have any creator tags but I'll link it here along with a few screenshots to help in identification. https://www.youtube.com/watch?v=pXQlrIVNzTE Any help in locating this song's creator and english lyrics would be much appreciated! ^-^
