Ichigo: chases Ulquiorra upwards and past the blue sky

Ichigo: Wait, are we above the canopy of Los Noches?

Ulquiorra: Yes, by Lord Aizen's command, two things are not allowed within Los Noches. The first is Gran Rey Cero which is only for Espada. The other is a sword release of an Espada of rank 4 or higher, both of which could destroy Los Noches.

Ulquiorra: Releases Resurreccion Imprison Murcielago!

Ichigo: Nope. Cuts hole in floor, drops back into Los Noches

Ulquiorra: What! What are you doing!?

Ichigo: Tauinting and slapping his ass Come on, chicken! Bauk bauk bauk come on!
