A picture book, titled 'Memento Mori,' written by Ohmori Motoki (Mrs. GREEN APPLE) and illustrated by Otani Tarafu, will hit store shelves on September 15. 

This book will be based on "Memento Mori," a song that was included in Ohmori's solo debut work "French" released back in February. It will utilize the original artwork from the animation that's featured in the lyric video for "Memento Mori" as seen below.
