Kawanabe Kyosai (1831-1889) was an artist of eclectic styles, but remains perhaps best known for his personal pantheon of demons, Hell creatures and night monsters, which he drew in ever-more elaborate configurations, driven on by alcoholic dementia. This mania peaked in the 1880s, augmented by explorations of infernal tortures and human butchershops. "Yokai Wars" is a special art ebook which collects two of Kyosai's most complete sets of colour sketches themed around demons, monsters, devil-animals, and visions of Hell. These 52 images, dating from 1879 and 1889, showcase the artist's deranged vision at its most inventive, delirious, darkly humorous and at times sadistic.
