Although the newest episode (ep. 15) does indeed lead up to something awesome happening I do feel this was one of the worst episodes yet.
I guess it suffers alot from the very fact that it's leading up to something major, so no harm done
I have to say I don't like the whole female trying to be male or visa versa thing, although many Animes seem to be using that, and she/he sounds rather lame at that ^^
