Chisato Naruse's Drops was released for Comiket 79 and has a rather unique and interesting theme; all of the girls pictured quite literally have water droplets on them. It's something you see often in illustrations, but I never thought about it being the focus of a collection ^^;
Wonderland is the latest illustration collection from Chisato Naruse, having been released during COMIC 1☆4 at the end of April. It's a compilation doujinshi, featuring her favorites from 6 years of illustration, 2003 through 2009. The only new illustration in this volume is the cover art work, featuring Chisato Naruse's version of Alice in Wonderland.
