name: kashiwa (meaning 'oak' plays on themes of age, wisdom and unmoving character.)
Element: Wind
sealed state description: A thin, rapier like blade, it is a hand-and-a-half gripped handle of pale blue. The blade itself is flexible (like a fencing blade) and deadly fast. It is strapped to Arden's side, where it sits without a sheath. It is not the strongest of blades, but very quick and lithe (mimicking Arden's own abilities). It can slip through almost all guard. The pommel of the blade Kashiwa is non-decorative, blunt. It is a rather plain zanpaktou.
shikai description: The blade is spun around and around - creating a vortex that soars into the air above Arden, and with a large amount of exertion (ie only three times each battle) it can be forced towards an opponent. Earth, trees and even people can be sucked into this cyclone. It lasts as long as Arden is able to continue spinning his blade.
shikai summoning chant: kaze o kashiwa! (wind of oak)
bankai description TO BE DISCOVERED. I'll come up with something after I explore Arden's character some more.
