DxD:Dimensional journey

Marcus has transmigrated in the world of High School DxD an act that excites him, since this was one of his favorite anime. Thus, he embarks on the path of magic in hopes of discovering how it works, the laws or theories that govern it; he wanted to find its essence. When Marcus finally discovers the answers to the question he was wondering about, he suddenly thinks to himself, "Since the world of High school DxD is real, what about all the other anime, movies, games and books that I read in my past life? And if they are really real, how can I get there?" This story is an Infinite Stream novel where the protagonist travels through different anime and movie worlds gaining various magical skills and knowledge to become a supreme god that stands on top of countless dimensions and universes. This is a Mary Sue and wish fulfillment novel, so read at your own risk and stop complaining. This is not a villain story, but rather a morally ambiguous story. Warnings: The protagonist will spend a long time in the world of High School DxD before going to other worlds. Even though this fanfiction will be a harem, the protagonist will have many women. Most likely, I will write so that he has certain relationships with some female characters, and then leave her in his universe. Only a few will follow him on his journey. Also, there will be some men in his group as well. THIS IS NOT A YAOI. Disclaimer: All the characters in this novel belong to Ichiei Ishibumi and I am just using them to write my story.
