An artbook anthology by Takano Kuratsune, as SQUARE or S²quare, who published this work under the circle Ushi-One for Comiket 41 (December 29th - 30th, 1991 - Harumi Fairgrounds). This is a compilation work of sorts with illustrations from 1988 to 1989 alongside new works in the beginning. Kuratsune published with Luna Industria and B-Club into the 1990s. I bought this from the mangaka Yuuji Iwaki at his storage at the old L.L. Palace distribution center.

Horikawa Kogoro and Inai Raito contributed work to this particular book in the back. The production quality on this book is very well done and the front two pages are printed on very fine parchment.
