Imprisoned Buuterfly Keyblade

This is a Keyblade I made, keyblades are weapons used in the Kingdom Hearts series, which have great powers and normally change with the keychain attached to it. In this case, I've drawn one of my invented Keyblades. Though this is for one of my friend, she told me I had the key to free her, when she'd have the guts, so here's the key that I'll use, if she feels like letting go of her chains~
