The story begins with a young boy named Kikori arriving at the massive defense city of Neulgen. He carries a simple axe and harbors memories of a past life on Earth, which have made him an outcast in his previous life. Advised by a kind priest to seek a new beginning, Kikori has come to Neulgen, a city that welcomes adventurers regardless of their origin, hoping to find a place where he can survive.
Upon entering the city, Kikori is stopped by guards who question his purpose. He declares his intention to become an adventurer, a path the guards warn is fraught with danger and a high mortality rate. Despite the warnings, Kikori is resolute, having chosen the name "Kikori" (woodcutter) to signify his intent to cut down monsters like he would trees. He receives a wooden token, a permit to enter the Adventurer's Guild.
At the Guild, Kikori encounters Gantz, a burly, veteran adventurer. Gantz, initially dismissive of Kikori's youth and simple axe, tries to dissuade him from becoming an adventurer, emphasizing the brutal reality of monster combat. However, Kikori's unwavering determination, stemming from his fear of being ostracized again if he takes on other jobs, leads him to insist on his path. Gantz, seeing Kikori's desperate resolve, reluctantly agrees to take him inside.
Inside the bustling Adventurer's Guild, filled with various races and seasoned adventurers, Kikori learns that Gantz has a reputation for looking after newcomers. The receptionist, a woman who seems to possess a keen eye, confirms Kikori's desire to be an adventurer. She offers him safer, more stable job alternatives, but Kikori, driven by his past trauma and fear of rejection, firmly chooses the adventurer's path. His axe is examined, revealing no bloodstains, only signs of woodcutting, which leads the receptionist to understand his chosen name. He is issued a bronze pendant, a "Bronze-class Adventurer" identification, signifying his beginner status.
Kikori receives his first quest: to gather Nibe grass, a common ingredient for minor healing potions. He is given a printed sheet with instructions, but being illiterate, he relies on the receptionist's explanation. The quest offers a meager reward, but Kikori is eager to earn more. He learns about monster subjugation and the importance of "magic stones," crystalline remnants of a monster's magic that can be used as currency.
He ventures out through the "Hero's Gate" into the "Contaminated Area," a dangerous frontier. He observes various adventurers and merchants selling supplies. A guard warns him that the area can be unpredictable, with powerful monsters sometimes appearing near the gate, and that the gate might close without warning.
Kikori searches for Nibe grass but finds none, as it's been picked clean by other adventurers. He encounters another adventurer who advises him to venture deeper into the Contaminated Area, where more profitable monsters reside, implying that less dangerous resources are quickly depleted. This encounter solidifies Kikori's resolve to face greater risks. He decides to hunt goblins, accepting the inherent danger.
Entering the forest, Kikori spots a goblin. He attempts a stealthy approach, but the goblin notices him. A fierce battle ensues. Despite his efforts, Kikori is outmatched and severely injured by the goblin's club. In a moment of desperation and self-awareness of his weakness, he laughs and fights back with renewed ferocity. He manages to defeat the goblin, experiencing the bitter taste of his first victory mixed with blood.
Returning to the Guild, Kikori, battered but alive, presents three goblin magic stones to the receptionist. She notes his impressive feat for a beginner, acknowledging that while the reward is small, his accomplishment is significant. He uses the earnings to purchase necessary equipment from the Guild's underground store, which offers a variety of weapons and armor, albeit at a slightly higher price due to the Guild's quality assurance. He examines various items, including a helmet and a shield, considering his limited funds and immediate needs. He learns that the shield he is looking at is more suited for offense and requires skill to use effectively.
