Hmm. How should I put it this time. I just remember seen thing while back.
I saw it on JUMP It was this Prince? Boy? But turned into a girl becacuse his Teacher took the ring from Him/her and the Teacher him self became a Woman. And the part I saw was like These 2 girls maybe one girl was fighting this Devil guy in this Tower thing..... Ummm.....
And the teacher went to fight some other army ish thing.
And was like. I'll give you back the ring after I win (Or something like that) beacuse atm I'm in woman's cloths.>>;
Basically Ring = Make you opposite Sex. And they were fighting something. --;

Oh and this is like Fantacy / Action manga?

If anyone know the name of this Manga / Manhwa tell me plox.

Please and Thank you.
