Yoshiki Takaya (高屋 良樹, Takaya Yoshiki?, born February 21, 1960) is a Japanese manga artist best known for creating the manga Guyver, which has been adapted into multiple anime features as well as live action films. Guyver was serialized in Shōnen Captain (published by Tokuma Shoten) for the lifetime of the magazine from 1985 to 1997. When Captain was cancelled, the manga moved to Shōnen Ace, published by Kadokawa Shoten, who also reprinted the collected volumes from the beginning. There are 29 tankōbon available.
Takaya began however as an hentai manga artist under the pen name Morio Chimi (ちみもりを, Chimi Moriwo?), with several works printed in the adult manga magazine Lemon People, published by Kubo Shoten. The best known of these is Hades Project Zeorymer, which was adapted as a four episode original video animation by AIC. He also had stories published in the manga anthology series Petit Apple Pie under this pen name.
