In fantasy stories, when the need arises to summon heroes to help fight in their world, they are always humans from the modern world, with no knowledge of magic or fighting, weaklings who must master and prepare to fight or also with some other occasional power and fight against a large number of enemies.

What if the summoned hero? He was a hero from another world, a holy warrior who protected his own world from humanity's greatest evil, someone who has already played his part, but now someone else needs him.

Sora, a Warrior with great skills, great knowledge and power over magic, mastery in martial arts, humanity fighting demons and mosnter preparing for calamity, the holy warrior returns to fight for humanity in another world.
