In this scenario, a person passes away and their spirit is transported to another realm. There, a deity selects the spirit and presents it with an offer: in exchange for granting them extraordinary talents, she requests that they utilize these abilities to safeguard her world from impending doom. The individual is then dispatched to another dimension, where they are endowed with the powers of a demigod. However, as power often leads to corruption, those who have been bestowed with these abilities exploit them for selfish desires and violent pursuits. One such individual is Zyzz, who serves a master from another world in his quest for his sister. Eventually, he encounters Kaina, who self-identifies as the "last summoned individual," having been personally selected by the deity to consume those who have breached their commitments.
