Calypso Lunaire is the God of the Moon who was punished to be reincarnated as a werewolf in the world called Iykios Sphere where the moon wolves and sun wolves live and fight endlessly. Calypso was punished because he accidentally tainted the moon with his blood, resulting in a blood moon, which created rampant chaos in different dimensions and worlds.

He bore the same name as soon as he reincarnated, and he discovered that he was reincarnated as a Male Werewolf Luna to the Moon Werewolves Pack. He then became their leader after prophesying that a Werewolf Male Luna would bring victory to his pack. As the battle started, he met Apollo - the Alpha of the Sun Wolves Pack, and they swore to be the greatest hindrance to each other's goals.

How will the fallen moon god adjust to a new environment and a new body? How will Calypso bring victory to the Moon Werewolves Pack? And where will the battle take Calypso and Apollo?
