Naoto Tenhiro is undoubtedly best known for his Sister Princess character designs and illustrations, so his style is very recognizable. When I spotted the Yoru ha Koneko de Isogashi (夜は子猫で忙しい) Illustrations as a Comiket 76 release, I didn't hesitate to get it because it was full color, and I'd already seem many of the illustrations in the visual drama that ran in Animage Magazine from 2005 to 2006. And as we all know, it's good to know what you're getting before you buy it!
