Tiger & Bunny creators Keiichi Satou and Kenji Saito announced a new book in their works called Demental Man: Lloyd no Carte (Lloyd's Clinical Records) which was featured as a trailer made and promoted by Kadokawa Japan.
Kenji Saito is the writer of the novel with Keiichi Satou illustrating the character designs. No word yet if there will be a published English translated version of Demental Man, but the book in Japan has a September 15 release.
Demental Man's story centers on a horrible virus called Demental, which changes the appearance of humans based on the darkness that lurks in their hearts. The only cure for Demental is the "Demental Men," medical specialists who can exterminate Demental. In ancient times, Demental Men exorcised demons. Doctors Cillian Lloyd and Tokio Lloyd, although they have polar opposite personalities, are a team based in Dreadnought City (a provincial city in England) that fights against Demental.
