Manga Chichi Chichi

Once, a close online friend of Chintarou asked a writer named Yorozu Hiraku if they could live in the same room while he was studying at a neighboring university. Although they knew each other only through online communication, Hikaru agrees to this without much thought. However, without Hikaru's knowledge, Chintarou, despite the male name, is actually a girl; very well-gifted girl.
