Ryu was your usual ordinary boy whom was bullied a lot. Ryu was teleported in a game along with 8B people. Each people obtained a unique skill that are useful.. well, except for ryu. He obtained a skill which allowed him to regress and go back in time to the new years before he was teleported to the game. However the game taunts, killing him for having not met the entry requirement of a minimum 5-man party. In his 100th attempt, he uses the information he learned from his previous 99 attempts.
