Chika Umino  

Chika Umino is a Japanese female mangaka, designer, and illustrator born in Adachi, Tokyo. She graduated from the Tokyo Metropolitan Art and Craft High School and uses the pen name "Umino." Her pseudonym comes from her favorite location, Umi no Chikaku no Youenchi (海の近くの遊園地, lit. an amusement park by the sea), which is also the title of her doujinshi works prior to her debut. She enjoys Harry Potter and anime by Hayao Miyazaki and identifies as an otaku. Umino still maintains contact with Hiroshi Kamiya, Mikako Takahashi, and Tomokazu Sugita, who voices Takemoto, Yamada, and Mayama respectively from the anime adaptations of Hachimitsu to Clover.
