Satoshi Shiki (士貴智志, Shiki Satoshi) is a Japanese manga artist and illustrator, whose works include Kamikaze and Riot. He's also an artist of hentai manga, and this influence can be seen even in his non-hentai works like Kamikaze and Daphne in the Brilliant Blue. He worked on XBlade in the magazine Monthly Shōnen Sirius, and then illustrated the manga adaptation of Attack on Titan: Before the Fall, a light novel that acts as a prequel to the Attack on Titan manga series, also serialized at Monthly Shōnen Sirius.
