@KomineShu Actually, the stakes for this game are pretty high: As said in chapter one, the winner inherits a corporation that apparently has worldwide power and gets more money and influence than he/she could ever dream of.
And honestly, the whole reincarnation-thing makes no sense anyway: He didn´t even die in the real world, he was just defeated in the game. I guess either this is a case of "because the author wanted it to happen" or we will get an explanation at the end of the story. But right now, MC is too busy with playing the game to find out why he went back in time.
