Akire's manga / #Friendship(23)

A truly educating, inspiring and entertaining adventure of a knowledge thirsty boy named Senku. With his friends, they embarked the journey to unravel the science behind the stone world they woke up to.

A spin-off of Attack on Titan which revolves around the story of a boy that had been mistaken for a titan child.

The friendship is great but the ending is not to my liking.
