Girls Book Maker (ガールズ・ブック・メイカー) is an eroge developed by Yumemiru, a new label from some big Japanese company. But compared to your average eroge, this one’s pretty unusual—it’s got a bizarre “setting” and “worldview,” with a dash of “cultural depth” thrown in. The plot: the protagonist is a bookworm who gets summoned by chance to a “library in another world,” where he works as the librarian and helps the head librarian exterminate the “bookworms” hiding inside books. Thanks to this setup, our hero can easily hop between “stories” with different worldviews, interact with “the heroines within those stories,” and go on all sorts of wild adventures. The books referenced are almost all classics: The Little Match Girl, Alice in the Mental Hospital, The Sino-Japanese Co-Production Journey to the West, The Phantom Thief Weak-Ass Gentleman Lupin, The Tale of the Bamboo Cutter Goes to the Moon, Gay Faust, and so on. These stories are not only familiar but should be no strangers to most eroge players—Alice, Kaguya-hime, Faust, Lupin have all been done to death in Japanese ACG works.
