The protagonist, Alto Crossford, awakens with memories of a past life as a player of the galge "Pure Love Cross." He realizes he has been reincarnated into the game's world and possesses a predetermined fate of death. Driven by a desire to save the game's tragic heroine, Sally Quist, he dedicates himself to becoming stronger, despite his low innate magical talent and average physical abilities. Alto's past life memories reveal that he is a "mob" character, destined to die alongside Sally during a demon god revival event.
To overcome his limitations, Alto focuses on a specialized combat style. He trains in swordsmanship, concentrating solely on the "Eight-Directional Stance" downward slash, and practices "Bullet," a rarely used, low-power, un-attribute magic projectile, aiming to perfect its accuracy for disabling opponents. His dedicated butler, Zeff, trains him rigorously, recognizing Alto's unusual determination and unique approach. Alto's parents, while supportive, misunderstand his intense training, believing he is solely driven by a desire to protect the Crossford family's honor.
Alto's goal is to prevent Sally's predetermined death, a crucial event for the game's narrative. He understands that simply following the game's plot won't work, as his low stats make him a liability. He diligently studies the game's mechanics and compares them to his current reality, discovering differences such as the absence of revival items and the existence of real-world phenomena like "Monster Panic" and "Monster Parade" driven by magic particles. He also learns that magic power is fixed at birth, unlike the game's level-up system.
To gain practical experience and improve his standing, Alto becomes an adventurer at fifteen. He takes on increasingly challenging quests, aiming to quickly raise his adventurer rank. His unique combat style, focusing on speed and precise, debilitating attacks, proves effective against lower-ranked monsters like goblins. He even manages to defeat a Bob Goblin, a stronger variant, by strategically using his "Bullet" magic to blind the smaller goblins and then exploiting the Bob Goblin's momentary distraction. This success leads to him being noticed by the Adventurer's Guild, with the receptionist, Mariena, recognizing his potential and reporting him to the Guild Master.
Alto also prepares for the entrance exam for the Royal Future Academy, a prestigious institution that promises a bright future. He has been studying diligently, often skipping regular classes to train, and has even developed an original un-attribute magic. He forms a friendship with a commoner named Couin, who also plans to attend the academy, and they support each other's ambitions.
Alto's growing reputation attracts the attention of a powerful A-rank adventurer named Cain. Cain, recognizing Alto's unique combat style and potential, offers him a chance to prove himself by participating in a Wild Wolf hunt, a B-rank monster. Despite the inherent risk, Alto accepts, seeing it as a crucial opportunity to gain experience against a stronger opponent and further hone his skills. Cain's intention is not just to defeat the monster but also to mentor Alto, allowing him to gain valuable combat experience with a safety net. The chapters conclude with Alto and Cain preparing for the Wild Wolf hunt, highlighting Alto's determination to defy his fate and protect Sally.
