"Money is a means, not an end. You should use it boldly when needed."
Jirou Ayase is the protagonist of the series, a 21-year-old from Japan who discovers a magical mirror linking his world to a fantasy realm. Suddenly placed in unfamiliar surroundings, he uses practical knowledge and creativity to build a new life. Over time, he grows from a modest street vendor into an emerging entrepreneur, property owner, and leader of a small but growing organization. His experiences—including confronting danger during travel—have encouraged him to train in self-protection. As he expands his business, establishes a knight order, and adapts to the customs of the new world, Jirou’s life becomes increasingly layered and demanding.
Jirou is a young Japanese man with a somewhat youthful appearance, often described as “neat” or "childlike." Upon first arriving in the other world, he wears a set of ornate, old-fashioned clothes found through the mirror—such as a frilled silk shirt and an embroidered vest—which give him a distinctive look. For formal occasions, he switches to attire resembling aristocratic fashion. He typically carries a bag containing self-crafted tools and modern supplies.
Jirou’s primary goal is to create a comfortable, stable life. Initially uncertain and overly cautious, he quickly develops a keen sense for business and negotiation. He is observant, analytical, and capable of bold action when necessary.
Though often nervous in unfamiliar situations, he demonstrates creativity, strategic thinking, and a willingness to adapt. He has a strong curiosity toward the customs, tools, and systems of the new world. A recurring comedic trait is his admiration for elves and other fantasy races, which often leads him into humorous misunderstandings.
Overall, he balances practicality with growing empathy, especially as he forms new relationships.
Before his journey, Jirou lived quietly in Japan and earned modest income through online reselling. After discovering the mysterious mirror in a cellar and purchasing it, he learned it was a portal to another world.
His cautious exploration led to his first encounter with the hunter Shello Roth and his daughter Rebecca, who provided shelter and guidance. With their help, he received the world’s "Blessing," revealing an unusually high number of abilities and a rare inherent job—marking him as someone with exceptional potential.
