This is a Japanese-language magazine about games and/or gaming.
Here's an excellent offering from Enter Brain: a set of two softcover books featuring design works from Alfa System's popular games. The first book is full color and its 328 pages have plenty of colorful illustration works of characters from games such as "Shikigami No Shiro I & II," "Lemuria," "Gunparade March," and other works. The second book is black and white, with its 194 pages full of design sketches of all characters from the three games named above, as well as "Umi Love" character design sketches. A must-have for fans of Alfa System's games!
