My first inspiration came from a movie about gladiators.Usually interested in science fiction such as multiverse, I developed the subject by incorporating courageous and strong Roman gladiators into the multiverse aspect. The imagined gladiator focused on the feelings and context of the gladiator facing defeat and loss, not the gladiator who wins the game and gains social status and wealth. And by incorporating multiverse elements, the story of a gladiator who found the inner power to withstand the ever-changing and growing multiverse was depicted in his imagination.
