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?'; and 'Why don't Titans have, you know, reproductive organs..?' 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.
