Kono Sekai wa Fukanzen Sugiru

A remote island south of the continent of Felnarc contains five densely packed countries in perpetual conflict. Within the smallest and most tranquil of these, the Kingdom of Bayle, a quiet village is home to Nikola, who leads a simple life. One day, while collecting firewood, she encounters a dragon, an animal believed to exist only in distant mountains. Before the creature can threaten the village, a man named Haga arrives. He is part of the King's Seekers, a covert investigative group. Though Nikola has never felt discontent with her routine existence, meeting Haga sparks her curiosity about his adventures, prompting her to venture beyond her village. Through this journey, she discovers the actual nature of her world.
