Monogatari no Kuromaku ni Tensei Shite

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. Suddenly, a notification message "Do you want to start a special story?" appeared on the screen.
