He was the hunting hound of the Baskerville family.

But at the end, he was branded as a traitor and executed.

Now, he has returned… after 40 years.

“This time, they will be my prey… and I’ll bite every single one of them to death!”

In the year 2025, humans awakened with the ability to summon mighty beasts—capable of destroying terrains, breaking the laws of physics, and creating wonders limited only by one's imagination.But before these blessings came a curse.An alien face appeared from nowhere and threatened all life on the planet, leading to the greatest war in human history.In the aftermath, the human race and the alien race were forced into a shaky treaty that could be broken at any time.Years later, tests for summoning abilities began for the next generation. Those who awakened low-grade summoning would be thrown to the gutters, while those who awakened higher got to join great factions after graduating from the academy.Kairos Veyl, the blank, calculating student, pulled his hand from the massive crystal pillar and stared at the large beast before him.“This kid—he just got a LEGENDARY SUMMON.”A legendary summon? The greatest class of summoning. However, with this class came a risk one would have never guessed.

Every night, he prayed. To every god on Earth.“Please, transport me to a fantasy world when I wake up tomorrow.”And then one day, his prayers were answered.Just not in the way he had hoped for.
