This guy called Sandoki is not the same character as Zando(the female one) although they look very similar to each other. He is actually containing another half of Zando's soul because in the past they were in the same body and were the great demon who wanted to drestroy the world. When it was defeated, its soul was shattered into 2 or more parts. One of them is Sandoki body, another one in Zando's and the rest is unknown.
Silly concept, huh? =P
Oh, one last thing, 'Smile' is his surname! ^-^
