Everything in this story is clearly fictional. Every character, every event even the planets and the universe's are fictional. This is necessary for the later story .
For example, I'll often say, Earth01, Earth02 and so on. But keep in mind that this earth and our real earth are entirely different. This earth is fictional and the city or places inside this earth are also fictional. Even the laws and rules of different world are only applicable for that specific world and has no connection with our real world. That's entirely fictional. So, don't be confused. I know most of the readers won't need this information but because I overthink, I had to write it as a chapter of auxiliary volume. Enjoy the read ! .
