With this set, I now have 3 different sets. I'm a key hoarder ._.
... I think you might have made an error there mate. Isn't the second from the right supposed to be Lira the Harp's key? And I've only seen up to episode 72 (I think), but she shouldn't have Libra or Pisces yet... should she?
Oh well. It's still totally awesome that somebody actually made a set of Gate Keys.
