It seems like you have to follow a special sequence to get "Leetena" in the first place. I try not to play with guides or cheats, typically, so I would probably not run into this problem myself, unless someone else pointed this out for me. Anyway, just found out about the translation I'm ages late, and the translation for Castlevania SOTN that happened on the psx too, grabbing them both. Reminds me of "Final Fantasy Tactics", where most of the content in the game wasn't accessible, so a few fan based remakes ended up being made, just getting one additional character would probably not add much to the replay value anyway.
