Tori is Sakura's older brother. And unlike most older brothers,
who seem to have a bit of something clueless going on, Tori seems to
be completely onto Sakura. He knows something is up, but also uncharacteristically
he lets her keep her secrets. This doesn't mean, however, that he lets
them be. He'll respect her right to have a secret, but he'll also make
her pay for that right dearly by teasing her almost endlessly about it.
Differences from the Original
Other than his name, Tori seems almost exactly the same. And I think
I actually like his voice actor. I'll have to see some more before I
come to a final decision, though.
