Uchida-san wa Zettai ni Gal ja Nai!

Présentation

During the high school entrance ceremony, the otaku Naruse Arata runs into a girl who looks exactly like "Ririchamu", his favorite girl from the manga Lilygal! His excitement was short-lived, though, because the girl turns out to be just Uchino Hida, a fellow otaku from his junior high school. She has a crush on Naruse-kun, and she had worked hard to remake herself to "look like" Naruse-kun's favorite gal. But Naruse wants a girl who is a gal on the inside, too! Can an otaku girl become a true gal? (Source: Comic Cune, translated)
