Reincarnated as the Mastermind of the Story

There was a globally popular game called The Legend of the Seven Heroes
Ren cleared the sequel of that game at 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 where Ren was about to give up the search he decided to start playing the second round of the game
Suddenlya 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
