Fatti, transmigrated to the world of DanMachi, starts with a fully-equipped arsenal of three magic spells and seven skills. Unfortunately, his potential is extremely limited, preventing him from seeing further. It's only after accidentally discovering a hidden treasure chest function that his life takes a dramatic turn. He opens invitations to recruit familiars from other worlds, acquiring various magic books and transforming himself from a mage into a noble sorcerer. With the goddess Demeter as his backer, he secretly accumulates strength, manages his familiar, and quietly develops his power. From then on, he cautiously and steadily begins his fantastical life in this other world.
