An addictive underground worldview full of very bad boys.This is the first commercial artbook featuring works by sakiyama, a popular illustrator with more than 110,000 followers on Twitter. Ruins, smirking wicked-faced young men, mysterious loners, a riot of wildly scattered flowers and more make up the dark and poisonous worldview that sakiyama is known for, but one that is also wryly humorous. sakiyama's animated music video production for "Kansaete Kuyashiiwa (so frustrated with my instincts)," a song by ZUTOMAYO, rocketed the artist's illustrations to international fame. sakiyama is also active across youth culture scenes, especially animated music video production and apparel collaborations.This book contains over 170 pages of original illustrations, including newly drawn artworks, cartoons, and music video illustrations along with rakugaki sketches posted on Twitter, making this the definitive collection of an illustrator who is at the cutting edge of modern trends.
