This theme is based off of one of my favorite Vocaloid songs called "Kagerou Days" or "Haze Heat Days" It's performed by Hatsune Miku and the composer of this song is Jin.
It's really an amazing song that will have you raping the replay button over and over. I absolutely LOVE this song and I bet if you guys go to YouTube, search for this song, and listen to it while watching its PV, you'll fall in love with it as well <333
I hope you like it!!~ Enjoy!~
