The Science of Attack on Titan- Rikao Yanagita, Hajime Isayama

This book of "fantasy science" answers all the questions it would never occur to anyone to ask about "Attack on Titan," such as: What do Titans have in common with bears? How many humans per day should a Titan eat to stay healthy and svelte? Why don't Titans have, you know, wieners? With original illustrations and very original takes on the world of the Titans, fans will find this a welcome break from Attack on Titan's dark tone.
