The full title is actually "About How I Accidentally Changed the Main Story of Hunter with My Secret Identities," but the title field on Shizi's site couldn't fit my interesting soul! This novel has no pairings; everyone is basically connected through friendship or family bonds!
Pro's young life ended beneath the wheels of a transmigration truck. He was then bound to a System, which promised to give him a revival coin as a mission-clear reward if he completed his tasks properly. Pro rolled up his sleeves and confidently declared that, as a League of Legends Master, he would live up to everyone's expectations and complete the mission perfectly. But the lousy System crash-landed. No, just as Pro reached the mission location, it suddenly announced that it was running low on energy and about to fall asleep, leaving him alone in an unfamiliar world without even telling him what the mission was.
...Well, since things have come to this, might as well get some sleep!
This can't be right. What kind of decent System kidnaps an innocent soul just to make him struggle to survive in another world? Pro brought out the same determination he'd once put into grinding games and analyzed the situation. The bad news was that the System really had fallen asleep and hadn't left a single clue about the mission. The good news was that the appearance system had arrived just in time. With only the cheat secret identities provided by the System to rely on, Pro began his struggle to survive in another world, then accidentally wrecked the original story's plot.
