The opening theme's composer, Hajime Kikuchi, sent rude tweets to well known voice actor and singer Momoi Halko. The original character does not actually exist. However, at the event, he was informed that he was actually appointed "Head of Public Relations" for the series. He was invited to the screening event as "a surprise voice cast member". Some time before this date, Mitsuhiro Ichiki auditioned for an original character for the TV series. I have merely summarized the events and more detailed information can be found via the source links.
