Ryu Shizuka (born August 4, 1993 in Tokyo, Japan), starts entering the manga industry as an eighteen-year-old entering the Treasure Award that was judged by Niizuma Eiji, who found his work amazing, something that his fellow mangakas agreed to. He later drew a dark manga series called True Human and was about to be the competition for Ashirogi Muto's KTM, but KTM didn't get serialized. True Human is the manga that Shizuka is currently working on. He was a shut-in since eighth grade, but because his editor motivating him to be more assertive, he moved out of his parents' house and into an apartment.
