Name

Under the battle of Good and Evil a long time ago, Roan's ancestors maked dolls (androids) and called them all for Tio, but they had different numbers.
I don't remember Tio's number, they say is two times in the game, but as I said...I don't remember her ID number.
All Tios looked the same and was only created to kill.

I'm not sure, but I've heard that Tio's name in the Japanese version is Teo. If it's true, then I understand why they changed her name to Tio in the American and European versions. Teo sounds and looks more boyish ^^

In Spanish, Tío means uncle. Byt they spell the 'i' a little different.
