A mysterious Type-Moon System recruits a young man through an irresistible offer: a guaranteed five-star pull, beginner bonuses, and a pocket dimension for storage. The true prize, however, is transmigration itself—a chance to become the protagonist of his own story. When he accepts and presses confirm, reality fractures. His consciousness shatters into darkness as a cosmic void consumes him entirely. The computer screen flickers with a haunting message: [Welcome to join us.] He awakens in Orario, a city teeming with adventurers, monsters, and divine beings. Armed with a system that defies the natural laws of this world and an inexplicable connection to countless heroines, he discovers he's not just another adventurer—he's the protagonist the system promised. But in a world where gods play games with mortals and harems are built through trials of combat and charisma, can he survive being the main character everyone is watching?
