The latest work from KEI, the official illustrator of "Hatsune Miku"!! In 2034, Mihashira Saya and Sayu are twin sisters who are good at fortune-telling and live in Hakoyanagi City, Tokyo. Set in a slightly advanced future, this is a slapstick comedy featuring the always energetic older sister Saya and her younger sister Sayu, who is always being dragged around by her sister!! Many unique characters appear, and each episode is an enjoyable omnibus drama, just like "Hatsune Mix"!! Of course, all the color illustrations from the original publication are also included!!
