Synopsis
The novels are then set in an era in which humans, led by the hero Cid, won the great war between the five races competing for supremacy on Earth. However, this world is “overwritten” in front of a boy named Kai. In the overwritten world, dragons and demons rule the Earth, and humans therefore lost the great war without the hero Cid. Therefore, the boy Kai, who is also forgotten by all humans, decides to recover the “true world” after meeting a mysterious girl named Rinne.
Kadokawa published the first volume of the novel in July 2017 and the ninth and final volume in August 2020.
Finally, the manga adaptation of Arikan arrived in Kadokawa's Monthly Comic Alive magazine in February 2018. Kadokawa published the first volume of the manga in June 2018 and the ninth volume on February 21st of this year.
