finding out that sekai's martial arts master and teacher was Kasshu, Domon. was what really made this series for me. that one flashback changed everything. I enjoyed the series more than I should have as an adult. I expected to watch 1 or 2 episodes but somehow got sucked into the hype. the energy this show gave off was like watching sports anime. and seeing what felt like two seasons worth of madness and fighting made it all worth it. much respect to this series. the characters were cliche and I get that wearing a tracksuit is an anime staple. but i guess the femalemember of the team was supposed to also be fan service. which i found strange.
