It seems obvious to me that Shiraishi’s phenomenon was engineered on purpose, because the script is written ahead of time. Sure, I understand that he appeared in drag to the first recording session. But by that time everything was already decided. The misterious “creators” have seen through him at auditions and knew what material they had to work with.
One day I would like to read a tell-it-all article about the genesis of Shiraishi the phenomenon.
UPDATE: Kurogane: “I think we should call it Shiraishi☆Star now.”
UPDATE 2007/10/25: “Shiraishi” and “Minoru Shiraishi” are top search queries on this site with a good lead.
