Tournament: My upcomming manga (2017)

One of my biggest dreams is to begin my own series. For years, I have had many different idea's, but because of my extreme insomnia in the past, i did nothing with these idea's. Now that i'm more well rested, i started writing a story, called Tournament. Next year, i want to draw it out in a manga form. The story is obviously about a tournament. There are eight gods ruling the world, who wish to be cured from their boredom every now and then. So they command mortals to fight in Arena's'. There are eight countries (Each god rules one, basically) which have their own Tournament which begins on July the 1st, and there's the World Tournament, beginning December 25th. The winner of the World Tournament will have their aging stopped for one year, and become King of the World, blessed by the Gods. Currently, the corrupted king Tormorok has remained the tirannic King of the World for fifty year, undefeated. And it is the dream of thirteen year old Delix Aurane, a young martial artist, to defeat the evil king and safe the world. So, what do you guys think of the idea? ^^

A couple of things: 1. I'm not sold on the premise. I get that you liken the dictator role to "Gods" which adds a symbolism of the mental captivity in binding yourself to a religion. But there isn't really much of a hook. It's a very archetypal story about a child saving the world. What makes stories long-lasting and potent, in my opinion anyway, is the ability to captivate on setting, story, and character. But any premise can be a good one. Yours just needs to be fleshed out more. 2. What audience is this going to? If it's kids then you can't get away with as many violent acts that show Tormorok's cruelty. But if it's adults then the message should be less...hammy. The idea of dictators driven by a lust for power is nothing new but there is potential. 3. Why should I believe that this 13 year old child has even the slightest chance of winning? Is he from some long line of fighters? Does he have a special trainer? Perhaps one of the gods favors this kid and backs their corner thus setting the stage for other gods to do the same. Capricious beings enacting a controlled chaos theory that shows just how warped such a tournament is in nature. But either way if I'm as an audience member expected to even slightly believe that this kid stands a chance then there has to be a reason. Think fullmetal alchemist for example. The idea of Ed passing the alchemy exam is ludicrous on it's own. But because we see that he spent all of his childhood studying, has a colonel supporting his endeavor, and can do alchemy without a circle, that makes up for the deficiency his lack of experience brings. Well, give me a good reason to believe that something tips the scales in our protagonist's favor. 4. This world is controlled by gods. Immortal beings who, by your story's own premise, care nothing for the lives of mortals and use them for entertainment. There is no sense of closure because I have no reason to believe that this cycle will end. At the very least give us a reason for this story to feel self-contained. 5. You clearly want the focus to be on tournaments. That's cool. I liked YYH, DBZ, and HxH as well and tournaments can be interesting. I will admit that your story sounds a lot like Shaman King at face value. But strong characters and differing motivations can more than make up for it. The bottom line is that Your idea needs more to it. Explanations, interesting characters, interesting obstacles, maybe a dash or two of subtle symbolism, and top it off with a good hook. It's not a bad idea but if you really want to, I'd recommend thinking more about the intricacies. Remember that your audience cannot read your mind. You need to invite them in.
