The organisation knows about the strongest power as well of course and kidnappes the human that is one half of it.

The multiverse (or meta-universe) is the hypothetical set of infinite or finite possible universes (including the historical universe we consistently experience) that together comprise everything that exists and can exist: the entirety of space, time, matter, and energy as well as the physical laws and constants that describe them. The term was coined in 1895 by the American philosopher and psychologist William James. The various universes within the multiverse are sometimes called parallel universes.

Setting: Japan (who would have guessed), modern times.Story: You play a fifteen year old, socially awkward kid named Shepherd. He moved to Japan about three months ago with his mother, who is the CEO of a multinational company, for business purposes. He is finally getting used to life in Japan, although he doesn't really have any friends, although being a nice person. He is also good at analyzing situations, and estimating how they will turn out, probably a skill derived from him playing video games for so long. One day as he is going out to buy the latest Shonen Jump (a collection of Japanese Comics), he notices a girl from his school, named Mizuno, at the crosswalk he is coming up to. The light flashes to walk and she starts walking through the street, but she doesn't notice a car coming straight towards her, as she has headphones in. The driver of the car is drunk, and he isn't going to stop. Shepherd decides to push her out of the way, getting hit himself. He wakes up in a pitch black abyss. When he finaly finds a bonfire, he meets another character. This character looks like an older version of himself, and asks him why he saved the her. Shepherd(15) explains that he knew she had a large family that would mourn her loss(when you are ignored you can pick up information much easier), while his mother would hardly notice his death. After a short conversation, Shepherd(15) wakes up in a hospital bed, and finds out he had been in a coma for the past three days. Soon after waking up, Mizuno comes to his hospital room, and explains to him how she had visited him every day, as she found it sad how none of Shepherd's family visited him. The two become friends, and after being discharged from the hospital and going back to school, people start to talk to him (although he is still socially awkward). But since he left the hospital, he has been having strange, extremely lifelike dreams in which he is in a strange world set in a somewhat medieval times, although there is a strange combination of magic and technology being used as well. He soon comes to realize that the dreams are very reminiscent of his day, and he also soon finds that things that happen to people in his dreams affect their real world counter parts to some extent.

I was thinking that while it seems that it's happening in his head as a dream, in reality he is going to different worlds in another sort of "form" of himself. The universe of the story is kinda a multiverse, but instead of the usual multiverse in which there is a universe for each choice a person makes (what I refer to as the mind **** multiverse), but instead there are a large number of "universes" in which there are some differences. IE. one "universe" may have a form of magic, while one may not, ect. The main character doesn't know that, so his only goal (to begin with) is to keep the people in his "dream" safe, so the real person isn't affected. As a side note, he may not keep the strength that he has while in his dream, but he retains his memories of all his fights, ie. he becomes an experienced fighter. So he doesn't really become physically stronger in the real world, but he becomes a more experienced one.
