What if Hikaru Utada (of Kingdom Hearts: them song fame) was a guest idol in a future Macross series? in Movies and TV Series Posted November 27, 2019 1 hour ago, DewPoint said: Utada Hikaru is HUGE in Japan and has been from the late 1990s. She is like the 12th best sell Japanese singer of all time. Unless she really likes Macross, an appearance in any form is highly unlikely. It a big pipe dream for me!
