send emails to Sega of Japan requesting that you want them to allow RyanDrummond to voice Sonic in Brawl.

Here's a link with some email addresses and more info:

If you really want Drummond to voice Sonic, send a couple emails to the email addresses on the link.

And, you don't have to translate your messages to Japanese, they know English.
