There was a globally popular game called The Legend of the Seven Heroes. Ren cleared the sequel of that game with the fastest record in the world, and thus he obtained a bonus special data. However, no matter where he looked inside the game, he could not find the data. The moment when Ren was about to give up the search, he decided to start playing the second round of the game. Suddenly, a notification message Do you want to start a special story? appears on the screen. When Ren chooses Yes without hesitation, he loses consciousness, and when he wakes up, he was a baby. - Could it be that he was reincarnated as one of the hero in The Legend of the Seven Heroes? Ren, who thought such a thing was impossible, could not believe his ears when he heard his name from his mothers mouth. It was the name of a classmate who betrays the heroes in the middle of the story. Of course, he wishes to live in peace. But in the game, he meets a saint whose life hes supposed to take, and doesnt. Furthermore, he ends up saving a character (the boss of a great noble family) who was supposed to die. All of these things creates a development that he doesnt know about coming to play
