Purification time!
Nicknames:
Levinse - When I first played through this game, I used Ledyba/Ledian too. I didn't have a nickname for it though, so I just looked up real names starting with L that could fit Ledian, and got Levin. And then I just added the beginning part of "insect" to it. I had a bit of trouble deciding whether to name him Levinse or Levince, but chose Levinse because the -vince part is too close to Vincent the Tauros in Brown.
Barkan - From -"bark" and canine/canidae. Again, debating whether it would be Barkan or Barcan.
