Wazu was an ordinary townsman who retreated into a remote mountain after a series of unfortunate events shattered his world. Rejected by the hero’s party and forced to leave his hometown, he spent two years in isolation, training alone to prove his worth. When he finally descends, he discovers that his childhood friend Aria, whom he once hoped to marry, has become engaged to the very hero who once mocked him. Heartbroken but determined, Wazu embarks on a new journey, vowing to grow stronger and build a new life—one that includes forming a harem of his own.

The story unfolds in a fantasy realm populated by humans, elves, and magical creatures. After leaving his village, Wazu rescues a young elf child named Sienna from an S‑rank dragon. Sienna brings him to her elf village, where her guardian Sarona is deeply suspicious of this mysterious human. Though Sarona attempts to investigate Wazu’s past and find reasons to expel him, his genuine kindness and overwhelming power gradually win her over. During a confrontation with a hostile elf named Gazna, Wazu effortlessly proves his strength and even declares his attraction to Sarona, setting the stage for a complicated romantic dynamic.

As Wazu travels, he is accompanied by Meru, a tiny puff dragon who saved his life when he was near death and whom he considers his first wife. The manga blends action, romantic comedy, and fantasy adventure. Notable narrative arcs include Wazu’s initial heartbreak over Aria, his integration into the elf village despite Sarona’s distrust, and the gradual revelation of his past through a talking guild card. The series balances overpowered protagonist antics with genuine emotional weight, as Wazu navigates misunderstandings, new bonds, and the challenge of finding his place in a world that moved on without him.
