This product is a two-volume set of spin-off manga for my original TSF novel ‘Girls world’. It offers a more economical price than purchasing them separately. The entire work is full-color and designed to be enjoyable even without having read the novel. (Reading it first enhances the experience.) Being full-color, viewing it on a ‘bright’ and ‘large’ screen may enhance enjoyment. Also, due to the time taken for production, the art style differs significantly between the beginning and end. Please be aware of this. Including fade-outs, text pages with illustrations, and bonus artwork, the older work is over 120 pages, and the new work is over 150 pages.
