I Want To Be Happy
1. Viola looks more or less as “classy” (if such a term can apply to fanservice-ripe Japanese lolita fashion) and stylish as Amy, at least to these undiscerning eyes.Well, I must admit her design is VERY close to Amy, but isn't Amy supposed to be the most classy and stylish female in the series? Besides, why would they not call her Amy if it was her??
2. Because of any number of arbitrary plot reasons. See the countless videogame characters who return in sequels with pseudonyms / alter egos / evolved identities / whatever.
Just as a purely random example, I will make up a 2-minute piece of crap fiction: “After Soul Edge was (mostly) destroyed, the corruption that had immortalized Raphael and Amy was abruptly wrenched from their souls, but only at a heavy cost: their minds broken, the two were separated and sought to rebuild their identities. Driven by the desire to recover her lost memories and find her origin, Amy turned to the arcane arts as taught by a nomadic mystic. Now, with the aspect of Soul Edge increasingly restored, the newly-christened Viola seeks its power to recover what she has lost – and perhaps rejoin the protector whose face haunts her dreams... and nightmares."
Blech. Tripe of the ripest variety. But I think the point stands.
