Have you watched the anime "Baki"?🥊 
This anime inspired me to play sports and never give up. Here is a brief description about this anime.

Baki is the son of Yujiro Hanma, the strongest fighter on our planet. From an early age, he trains hard in order to surpass his tyrant father and get even for all the suffering he caused. In an effort to achieve his dream as soon as possible, Bucky fights with fighters from all over the world and tries his hand at fighting without rules, where he shows himself a worthy opponent. But life throws the hero more and more obstacles on the way to his goal — five of the most dangerous criminals imprisoned in different parts of the world have escaped from their prisons in search of a meeting with him. Will Bucky be able to defeat them? Or is he going to feel the bitterness of defeat for the first time in his life?
