Grimmjow is repetitive :D This video features mainly him as well as appearances by Ulquiorra, Nel and Szayel.
Aizengard = Las Noches
I do not own Bleach, Tite Kubo does. The original song and video is "They're taking the Hobbits to Isengard" by Confessant/Erwin Beekveld.
I never want to hear this song again, lol.
