The protagonist, a disillusioned modern Japanese man, found his bleak existence of "black" jobs unbearable. He frequently dreamt of a past life as a "Hero" in a fantasy world, a life of constant battle, public pressure, and a tragic, mutual kill with the Demon Lord. Despite its hardships, he preferred the Hero's life for its meaning and companionship, unlike his lonely modern reality. His modern life ended abruptly when he was hit by a truck, leading him to a mysterious space where he met Elmaria, a chatty, JK-like "First-Class Management God" overseeing reincarnation.
Initially seeking a peaceful, ordinary life, the protagonist soon realized his true desire was to return to the Hero's world, which felt more like his "hometown." Elmaria, surprised by his unusual request, informed him that 51 years had passed, the world was now peaceful, and his acquaintances were likely gone. Despite her warnings, he adamantly chose to return.
Upon reincarnation, his body materialized in a dilapidated hut. He was immediately reunited with Morin, his former Sage companion, who had summoned and trained him in his Hero life. Morin, appearing unchanged despite the decades, revealed the "Mark of Servitude" connecting their souls, a magical contract from their past. She expressed concern that his Hero-class soul could destabilize the peaceful world and insisted on staying by his side to monitor him. No longer bound by the constraints of heroism or modern-life timidity, the protagonist embraced Morin, deciding to live without restraint, and they rekindled their intimate relationship.
The next morning, Morin, now in a maid outfit (a new cultural import from other reincarnators), served him coffee. She guided him to the Adventurer's Guild to secure his status. There, they met Eliza, a friendly receptionist who was flustered upon recognizing Morin as a legendary figure. The protagonist, unable to read or write, registered as a Lv1 "Hero" with astonishingly high stats, which Morin subtly masked with magic. He chose the name "Orion" and declared himself 17.
Deciding to buy a mansion, the protagonist discovered Morin had no money. In a single day, he delved into a dungeon, cleared ten floors, and returned with 1,000,000G, astonishing the merchant. After celebrating his new wealth and home with Morin in a private bath, he encountered a slave girl imprisoned in a wooden cage. Drawn by her defiant eyes, he bought her for 200,000G, intending to free her, despite Morin's warning that it was a crime to destroy property. The stubborn girl, a beautiful tribal chief's daughter, insisted on staying with him as he was now her owner. He brought her back, cleaned her with a deck brush, and Morin provided her with a maid outfit. The protagonist, Morin, and the slave girl prepared to move into their new mansion, embarking on an unconventional life, free from the burdens of world-saving, focused instead on personal desires and building a unique household.
