Corona

Corona (クラウニング) are weapons that can be used by Axel in Kingdom Hearts 358/2 Days. It can be upgraded to Corona+.

A corona is a sort of "atmosphere" of plasma surrounding the sun and other heavenly bodies.

Design
A Corona chakram's main wheel is actually comrpised of eight protrusions of alternating small and large sizes. The four smaller protrusions are roughly square-shaped and are red with a black outline. The four larger protrusions are similar in shape to the ones found on Sizzling Edge and resemble squared-off arrowheads. These too are red with black outlines. The handle is a light blue cross that attatches to the four larger protrusions.
