Taeko Kawata on her site:
I have been co-acting with Mr. Jun’ichi Kanemaru all along in the anime Sonic X series and in the game characters. Mr. Jun was always a leader in Sonic X series, and he did things like bringing us the coactors to delicious meals and having a good time in Yokohama with everyone…. He is a great big brother even outside the job.
I will duet with that Mr. Jun as well this time. It is an impossible situation in the anime! The wish of Amy, who is continuing to be madly in love with Sonic … will come true here?!
