Izumi Takemoto(竹本 泉Takemoto Izumi) is a mangaka born on January 19, 1959 in Tokyo, Japan, though he grew up in Saitama. He attended Nihon University and majored in business. His first experience with science fiction was through the works of Edgar Rice Burroughs, and the majority of his works reflect this SF influence. He is also a cat lover, and while cats frequently appear in his works, he had never owned a cat until 2003. He used his first experiences with his cat when he wrote Aru Hi no Zwei.
