3 - 31: The Terror of Invisible Lucy

Lucy uses a 7 year old potion whilst taking a bath. But it seems that 7 years is a lot, even for a magic potion, and the effect turns Lucy invisible. Fun at first, it puts her in quite the predicament and she hopes her fellow Fairy Tail members can help her turn back to normal.
