I'm not an anime book award judging organization. My knowledge is limited to the text and data I've come into contact with. However, if you have any information about the anime and book awards, you can check the relevant websites or social media groups to learn more about the selection criteria and results.
'Attack on Titan' is also very popular. It's set in a world where humanity is on the verge of extinction due to Titans, giant human - like creatures. The story is dark, gritty, and full of mystery. It keeps readers on the edge of their seats as the characters fight for survival and try to uncover the secrets of the Titans.
