From the publisher:

The first art collection from the illustrator who has created images for numerous singers' music videos, Chachagoma!

Chachagoma is an illustrator who is active in Japanese 2D visual pop and anime culture including music video and novel illustrations, character design and more. Beginning with illustrations for music videos, album jacket designs, and merchandise for musicians such as Mafumafu, Amatsuki, and Matsushita, this collection also features illustrated art works and illustrations used in merchandise collaborations. From adorable works featuring penguins, chicks and other birds together with little girls, to boys with jet-black wings like a demon's, angels, and other anthropomorphized beings, this collection is full of charming characters. This monumental collection offers a complete overview of Chachagoma's work in commemoration of their tenth year working as an artist. Chachagoma's sensitively rendered translucent watercolor works, including forty artworks created for this collection, are now together in one volume. We hope you will enjoy these works of Chachagoma, a leading illustrator of Japan's online music video world who is also tremendously popular among young fans from the Japanese anime generation.
