Millón Escudo

is a Kidō spell. While both the number and classification of this particular spell is not expressly stated, it most resembles a bakudō (binding) spell.

Description
A light green, hexagonal barrier which is normally fixed to one central area and, when inactive, remains invisible. Upon contact with an outside force, the barrier enlarges to fully to protect whatever it is affixed to. The barrier protects from the attack, keeping it away from the target, gathers the energy in one area, and, momentarily absorbs the energy from the attack, forces the attack outward and away from the shield in effect, dispersing the attack altogether. It is powerful enough to block a point-blank Hollow mask-enhanced Getsuga Tenshō from Ichigo in his Bankai.
