haiyore! nyaruko-san

The recently released collection Koin Illustrations contains art work from the light novels Haiyore! Nyaruko-san, Metal Witch Sisters, and Hauhau. Though Koin is probably best known as the illustrator for the popular series Kanokon, art from that series isn't included as there's already been an art book dedicated to it called Foxmark Kanokon Art Works.
