あらすじ
In a world of sword and sorcery, the Kingdom of Nor, one of the four allied nations at war with the Demon Lord, attempts to defeat him by summoning a hero from the modern world with a secret spell. However, the hero who appears is a soulless serial-killer. The name of the "hero" is Kagei Soji. He makes decisions based on his own whims, without regard for reason. Immediately after the summoning, under the bright blue sky, he kills the princess and her guards, and escapes from the castle.
