It teach us that even we are at the bottom, we can always reach the top if we put effort and training. Don't always judge a person by rank or level, even if we don't have any talent or luck, we can overcome it with hard work. Light novel has already plot it's story more than 3 seasons, the first season of the story is only 3 volumes of the light novel. I hope we can see the action of ikki and Stella fight together. Because they already promise to fight with each other at the 7 stars sword art festival.
