The World is Full of Monsters, So I Want to Live as I Wish

While heading home from work, Kudo Kazuto accidentally strikes a mysterious dog with his vehicle. Immediately after the incident, an unfamiliar voice echoes through his mind, coldly announcing that he has earned experience points and advanced to Level 1. Dismissing it as exhaustion, he returns home, unaware that this bizarre notification marks the beginning of a terrifying new reality. By the following morning, the world Kazuto knew has been completely transformed. Vicious monsters now roam freely, turning everyday life into a constant struggle for survival. Reality itself operates under a game-like system governed by levels and skills, where lethal danger lurks around every corner. Humanity is suddenly forced to adapt to these brutal mechanics or perish in a landscape defined by chaos and relentless threats. Armed only with the inexplicable system interface and a unique special skill granted during his strange encounter the previous night, Kazuto must navigate this hostile environment. To endure the nightmare unfolding around him, he will need to grow stronger by leveling up and mastering his newfound abilities. His desperate fight for survival begins now, driven by a single goal: to live exactly as he wishes in a world overrun by monsters.
