Magus Gravity

This is about a person who is summoned to a world to be a hero and save the human race from the demons, clich stuff, he will then make decisions that affect all of those around him(I think this is original). Also, he will not get all the \"\"\"\"females\"\"\"\" out there in the other world and make a big harem that symbolizes how woman are treated as objects. Remember that this story is something I would like to read, and frankly most of the royal road stories are too damn lusty and filled with porn. But there will be some romance here and there since people get married and I need to talk about that too, so that is classed as romance right?
