We were born in a distant world.

Our mother left, and the world died.

A grey flower, but with the scent of our mother began to cover the world.

The world is about to be reborn

So we decided to pick the "hyka", the grey flowers.

(From "hyka" serial 0)

Girls living in a decadent, yet beautiful world.... In the past few years, reoenl has been creating illustrations of characters with various worldviews and backgrounds and has been releasing them through social media and doujinshi (self-published fan magazines). The story "hyka," which was serialized on PIE International's official website, has become a universe that contains all of reoenl's creations. This book is made up of two parts: a booklet summarizing his unique worldview centered on "hyka", and a booklet summarizing various commercial works. It is a must-have complete art collection for fans who want to immerse themselves in the unique and all-consuming world that reoenl creates.
