The female protagonists of the Pokemon series, May is the 10-year-old daughter of Petalburg City Gym Leader, Norman. She has a younger brother named Masato who is a budding Pokemon leader but far too young to receive his own pokemon yet. May starts out as a girl who doesn't like pokemon but found interest in participating in Pokemon Contests. Quite a difference to Kasumi, who dreams of becoming the World's Greatest Water Pokemon Trainer.
Cute pair aren't they? I never got to follow the Pokemon series all the way. I may have stopped after I saw the movie with Mewtwo in it. But anyway, beautiful cosplay!
