A Boy Who Picked up Cerberus, After Being Expelled From His Party, Turns Out to Be a User of Extinct Ancient Magic and Rises to the Top With His Beloved Dog

Souta, a member of an S-rank party, is suddenly told by his comrades that he’s being expelled during a mission. To preserve the party’s reputation, they tell him to “die in the line of duty” and throw him off a cliff.

As Sorta resigns himself to death, he’s unexpectedly saved by Cerberus, who was banished from hell.

Moreover, Cerberus declares his desire to become Souta’s familiar and reveals that Sorta is a user of ancient magic.

Ancient magic is far more powerful than modern magic, which has become extinct in the present day.

As a user of ancient magic, Souta gradually grows as an adventurer, mastering his abilities.

Meanwhile, Souta’s former party, unaware that they owe their S-rank status to his ancient magic, faces a tragic fate.
