I was thinking Ryoko Shiraishi was going to be the one to play him since she tweeted about meeting Mayumi Tanaka for the first time not too long ago, is already working on a current Toei show, and has that deep, husky female delinquent voice downpat. Hayami definitely has range, but this is definitely playing against type for her!
