The story follows Arius Gilbert, who has reincarnated into the world of the otome game "Love Academy" (KoiGaku). Unlike the other students at the Royal Magic Academy of the Kingdom of Ronadia, who are engrossed in romance, Arius, as the son of the Prime Minister, has no interest in such matters. Instead, he dedicates himself to exploring dungeons and becoming stronger, treating the world as an RPG.
From a young age, Arius displayed exceptional talent, able to manipulate magic instinctively and train his body with it. His parents, Prime Minister Darius and his wife Leia, recognized his genius and provided him with excellent tutors. By the age of five, Arius had mastered up to fifth-tier magic and possessed combat skills far exceeding those of the game's plot points. His parents, former adventurers themselves, hired two renowned adventurers, Gray and Serena, as his tutors. Gray and Serena, initially skeptical, were impressed by Arius's potential and agreed to train him rigorously, treating him not as a child but as a fellow adventurer. They pushed him through intense combat training, including fighting monsters and, eventually, learning to kill humans when they encountered a bandit group.
Over the next few years, Arius's strength grew exponentially. By age seven, he became an adventurer, surpassing the age requirement through a special exception facilitated by Gray and Serena's influence. He quickly proved his worth, clearing dungeons and earning recognition. He formed a party with Gray and Serena, who, despite their immense power, adjusted their pace to match his growth. During this time, he also encountered Jessica Lowell, a B-class adventurer who initially challenged him out of jealousy but eventually came to respect his abilities after a swift defeat.
By age ten, Arius had conquered numerous high-difficulty dungeons and was on the path to tackling the world's most challenging "top-class" dungeons. His parents, while supportive of his adventuring path, also reminded him of his potential future role as Prime Minister, insisting he continue his studies and enroll in the Royal Magic Academy at age fifteen.
At age eleven, Arius and his party, Gray and Serena, began their assault on the "Dragon's Palace," a top-class dungeon. Even at this level, Arius's strength had grown to the point where he could fight alongside his mentors, though they still held a significant advantage. Their ultimate goal became the world's seven "ultimate-class" dungeons, where they faced overwhelming numbers of powerful monsters, including legions of angelic beings. Arius's journey is characterized by his relentless pursuit of strength, his unique perspective as a reincarnated individual, and the unwavering support of his mentors and loving, albeit "overly doting," parents.
