Okay, so recently I've been listening to/watching Vocaloid videos, and I can't stop. This one, Witch Hunt, is probably my favorite. Megurine Luka is the main singer in it, accompanied by Gakupo, Miku, Rin, and Len. Oh mah gawd, I love who amazing Luka and Gakupo's voices sound together! I ship them so much! >w<

Anyways, the video is a little confusing, so I'll give you a summary of it.
CAST:
Luka: Witch/Angel (what she is isn't specified)
Gakupo: Prince
Miku: Nun/Priestess
Rin and Len: Narrators/Townsfolk

One day, a girl (Luka) and the prince (Gakupo) fell in love. They spent a lot of joyous time together. The priestess was not happy with this, and was jealous, for she secretly loved the prince. She then ran to the prince, lying and falsely accusing the girl of being a witch, and that he was under her love spell. Being part of the church, the prince hesitantly believed her and followed with what she did. The priestess then went to the church, asking God for his forgiveness in her sins and wrongful doing, because she wasn't done. The prince then cut off the girl's hair, and him and the priestess tied her onto a cross in the center of the town. Before she could be crucified, a pair of angel wings, darkened with despair and betrayal (the prince had turned on her, so she became a fallen angel), and she freed herself from the cross, flying away, never to be seen again.
