Idea for Alternate Kyoka Suigetsu's Ability (+ Bankai for it)

Shikai: Kyoka Suigetsu "two-step" ability that makes Aizen invisible, then creates illusionary copy to appear nearby (effectively, the same "trick" that he used on Hitsugaya in Soul Society Arc)

Bankai: Mugen ni Kudaketa Kagami (Infinitely-Shattered Mirror, according to Google Translate) The same ability that in Shikai, but can create "illusionary copies" of anyone near Aizen (while causing "originals" to be invisible to anyone other than him), and can create multiple illusions

Effect: Powerful illusion-type Zanpakuto, with a Bankai that's "practically useless" for 1v1 fights
