Kogane Tsubasa (Golden Wings)

Weapon Name: Kogane Tsubasa 黄金翼 (Golden Wings)
Owner of Weapon: Cathy Felinius
Type: Parasitic
Open Appearance:
Large golden wings that sprout from Cat's back. The feathers of the wings are very sharp, and will cut through skin. The feathers usually end up coloring the skin gold.
Closed Appearance:
When closed, Cat can just fold the wings inside her clothes, making her appear 'normal'.
Weapon Abilities:

Hane no Arashi 羽の嵐 (Feather Storm):
When Cat spins, her wings can let loose feathers that act similar to arrows. They slice through the skin, wood, and iron very cleanly. The wounds are so clean that they appear as if one cut them-self with a sharp and smooth knife. This move is destructive, but it takes time, as well as accuracy. It also takes a lot of stamina, and Cat is usually pretty dizzy afterwards from spinning so fast.

Umo Bakuhatsu 羽毛爆発 (Feather Explosion):
Cat can also throw some feathers around, and they can detonate. The explosions leave powdered Innocence in the area. The powder burns the skin of Akuma and will sometimes create holes through the skin/body if the powder is concentrated enough. This ability also takes some time and precision. However, the feathers always grow back, so it is almost unlimited, unless Cat runs out of stamina.

Kaze Surasshu 風スラッシュ (Wind Slash)
When Cat flaps her wings hard enough, she can create gusts of wind that are oddly formed in a way that causes the wind to be sharp instead of blunt and forceful. These gusts of wind can slice enemies in a cross-like way. Think of an 'X'-shaped gust aimed at the enemy.
