Haigakura is a manga set in a world with lords. This world exists above the sky and below the ocean. Four evil lords used to support this world but ran away, taking all the minor lords with them. Because of this, special people called Kashikan were needed to capture the runaway lords and restore stability. The main character, Ichiyou, is a Kashikan. He took the job to free his foster father, a tiger, who was captured to replace the missing lords. Ichiyou’s goal is to recapture the evil lords and bring back the peaceful life he once knew.
