So what exactly was his mission in this world. It was actually quite straightforward and something that Rein liked. There was a powerful monster sleeping in the core of this world. This monster was actually like a ticking time bomb for this whole world. Rein's mission was to get this world rid of this troublesome monster.
Killing the monster off was the most direct solution but this monster was just way too strong. So if killing was not possible, then just getting this monster out of this world would also be a solution to this problem.
So if this monster turned out to be stronger than Rein by a huge margin, then he would need to find some way to get it out of this world. So he was also thinking of various ways to do so. Rein only had one symbol in this world.
