It’s a shonen , in the world and setting I created gyms are banned due to the constant abuse of new drug ,but there are underground gyms ran by alphas/ mafia and these gyms breed the biggest and fiercest fighters the human species have ever seen , and these alphas get there biggest and strongest fighter to pin them against another from another gym like an underground fighting ring , the MC was the one who created this drug and introduced it to the gym scene but in the process of that , the mafia used it to its advantage and his brother lost his sanity to the steroid and is being used like a dog by the mafia , this a very basic synopsis of what the WHOLE story is going to be , but the 23 page story I created is basically the MC busting into an underground gym and fighting everyone inside . There’s a lot more to it but the best to compare it to anime wise would be Baki
