I'm going to write my thoughts before we head into the actual fanfic.
The MC will be reincarnated of course and will be able to travel different worlds.
He will be opish because he is going to several worlds where conflicts exist.
In some, he will help with the conflict but in others, he will not because he wants to stay neutral and watch the events unfold.
HOWEVER, he will 'encourage' the side he 'favors'. You will find out what I mean by this in the novel.
The MC will not be a brute who solves everything through violence.
Some worlds will somewhat follow canon and others will not follow canon because why not.
I'm not entirely sure which worlds he will be traveling to. The first world will definitely be Artifureta.
The story will be slow-paced following what happens in the world. Don't expect too much conflict.
Now EnJoY...
P.S I don't know if you will finish this novel. I mean I did write it on a whim. Let's see how it does and hope I don't drop it. Also don't expect many chapters released each week.
