Round Fan

Round Fan (ラウンドファン) is Xemnas's joke weapon in Kingdom Hearts 358/2 Days. They are actually fans in Xemnas's hands.

Design
As the name would suggest, the Round Fan ethereal blades are uchiwa fans (stiff, unfoldable fans often used to fan flames). The handles of these fans are white, while the upper halves are purple. Obviously, these ethereal blades do not glow.
