About

In a world consisting only of a vast ocean inhabited by countless monsters, there floats a single, massive aerial island: "Dran Continent." The inhabitants here all wield magic, and the world is governed by "Ruin Academy," an institution that trains mages. Guest was born here and is the reincarnation of "Karun," the hero who saved Dran Continent from an unprecedented monster invasion hundreds of years ago. Karun was the only person in this world capable of casting magic without incantations. Guest was born with memories of his past life but under a completely different name, living on the streets. However, the winds of fate are beginning to blow once again in his new life. > Every human on Dran Continent can use magic, and magic is divided into ranks: S -> A+ -> A -> B -> C -> D -> E. S-rank is the highest, and since Guest is the reincarnation of Karun, he is naturally S-rank. > Every human on Dran Continent has their own familiar. > If a human and a familiar fall in love and marry, a contract called "Soul Union" is formed, merging their souls. > Once a human and a familiar perform a Soul Union, the human will always return to their partner even after death.
