When K-books turned 15 years old in 2008, a collection consisting of artbooks, special phone cards and many other products was released, to thank its customers. Please read the below notes carefully for the contents of EACH volume.Note #1: This collection comprises of 2 separate artbooks as in, 1 for the boys and 1 for the girls. The particular names are Boys side and Girls Side and neither of the 2 are likely complete. Note #2: Boys' side = often ecchi and with some images featuring some nudity. One of the images was lolicon, soo I left it out in accordance with Batoto's site policy. I mean: you don't want me to start censoring by drawing on someone's art, right? The image in question was by Kiyotaka Haimura, if anyone's extremely curious. Girls' side = mostly shounen-ai but some of the images are not. Nothing that really qualifies as "mature" for this artbook.
