The story begins with the protagonist, Ficel, on his deathbed, surrounded by his elven companions who express their sorrow and their wish for his reincarnation. Ficel, a human, laments the lifespan difference between himself and the elves. He reveals his dying wish is to use a self-developed, legendary magic called "Reincarnation Magic" to be reborn, hoping his companions will welcome him back. He expresses his desire for them to live freely and find happiness, even if he doesn't return.
The narrative then flashes back twenty years to Ficel's childhood in the magic-advanced Highhorn Kingdom, bordering the Demon Kingdom and the Elven Kingdom. He recalls the constant conflict with monsters at the border and the elves' passive observation. As humans developed magic and weaponry, monsters became a source of income and glory. When Ficel was twelve, the Demon King attacked the Elven Kingdom, leading to its swift collapse. Rumors suggest the Human Kingdom was involved. Following this, elves lost their human rights, becoming prey for monsters or sold into slavery. Their beauty and superior abilities made them highly valuable in the kingdom's black market.
Ficel, now twenty-five, unaware of this plight, celebrates the kingdom's recognition of his "Full Potion," a complete healing potion he developed over seven years of self-study after his father's death in battle due to a lack of healing potions. He secured a patent and anticipates immense wealth by selling a diluted version to the kingdom. His mother passed away before he could fully repay her.
While contemplating his newfound fortune, Ficel is approached by Gelg, a renowned merchant with whom he contracted to sell his potions. Gelg invites Ficel to the "underground," which Ficel initially misunderstands. He is led through narrow, dark alleys to a hidden entrance guarded by a hooded figure. Upon entering, Ficel is shocked to discover it's an "Elf Auction House," where elves are sold as commodities. Gelg explains this is a grim reality of the world, a consequence of victory and defeat.
During the auction, Ficel witnesses the brutal trade and, despite the grim atmosphere, impulsively bids a staggering ten million on a severely injured and ill elf girl, identified as #98. He purchases her, defying Gelg's surprise and the auctioneer's confusion. He learns about the magical collars that enforce obedience and the rules of elf ownership. Ficel, carrying the girl, uses a "Teleportation Orb" to reach his inn. He administers his precious Full Potion, which miraculously heals her injuries and illness, causing her immense pain and a subsequent outburst that alarms the innkeeper.
The next morning, the elf girl, now healthy, mistakes Ficel for her former master and begs for punishment. Ficel reassures her, revealing her recovery. She expresses gratitude and pledges her loyalty. Ficel names her "Vel" and takes her shopping for clothes and necessities, noting her submissive demeanor and his own lack of experience in such matters. While eating, Ficel learns from Vel the harsh reality of elf treatment: women are often bought for sexual gratification, and men for labor. Vel questions Ficel's motives for treating her kindly, but he states he simply saved a life he could.
Ficel contacts Gelg to inquire about upcoming elf auctions, seeking to hire guards. Gelg arranges for Ficel to attend an auction that evening, where war spoils will be sold. Ficel, accompanied by Gelg's subordinate, attends the auction again. He witnesses the sale of a former elven knight captain and, despite the overwhelming atmosphere, impulsively buys a pair of twin elves, Ban and Aina, who were blinded and sold separately. He learns they were renowned knights.
Ficel brings Ban and Aina back to his secluded home. He reveals his intention to remove their collars and explains his plan to develop magic to locate all elves and teach them how to create Full Potions, aiming to help them rebuild their nation. He also hires a renowned chef named Dunning, whose tongue was cut out, and a cursed elf girl named Shizuku, who has five days to live. Ficel dedicates himself to deciphering Shizuku's curse, using his Full Potions and a potent energy drink to maintain focus. He struggles with the complexity of the curse, but Shizuku's desire to live and the kindness shown by Ficel and his growing group of companions fuel his determination. The narrative concludes with Ficel successfully removing Shizuku's curse, though the exact method and its implications are not fully detailed. The story sets the stage for Ficel's ongoing efforts to aid elves and potentially change the world's perception of them.
