My Zanpako-tu name is KageIchi
based on his name, as soon as I release it can absorb and mimic all opponent ability
and my bankai.....I never used it because every opponent that I fight powerless with my shikai Step(fufufu...)
but I will tell you (sssttt.... this is secret so don't tell my opponent about this)
IN Bankai step I can create 10.000 Shadow clone of Opponent that I have been Defeated, not illusion but reality clone.
(Sorry for bad Spell)
