A Genius who Fell into darkness. The God of the Underworld.
Akagi runs from a game of chicken where he almost died, to a Mahjong parlour where a man loses all his money to the yakuza. Akagi, who is only thirteen, tells the loser that his game needs improvement (although Akagi himself has never played before). Akagi replaces him in the game, and so a legend is born.
When the police come to check on the place to see if the kid that ran from the game of chicken is there the yakuza deny that Akagi was involved. In the end the policeman invites Akagi to a much more organized Mahjong game and from there, the legend of the Genius who Fell into Darkness continues to grow.

"Hard working" or "passionate" was not in Sakurai's vocabulary and joining a team sports in school was out of the question. But one day, he accidentally walks in on his female classmate Toyoguchi naked in the locker room and in return for keeping it a secret from everyone else, he is forced to become the manager for the female lacrosse team. Toyoguchi is passionate about lacrosse and was responsible for creating the team for the school. Sakurai reluctantly begins his role as manager but is slowly drawn into Toyoguchi's personality and begins researching and enjoying the sport. The once lazy Sakurai who was scared of failure now learns to put himself out there and put serious effort into something worthwhile.

This is a mixed martial arts fighting manga about the Miyazawa school of martial arts. Initially, it is about Kiichi trying to heal his father after he was nearly killed by his brother Kiryu. But then it goes on to be less about that as his father recovers and some tournament style fighting begins. At that point various apparently overwhelming opponents will encounter Kiichi on his way to the top. The objectives of the various characters start to play a more and more important role, as well as the different philosophical projections of several martial arts and disciplines. (Somewhat maybe like a modern day Samurai story.)

This is also a continuation of Koukou Tekkenden Tough which followed the main character, Kiichi, when he was younger and was training under his father Seiko Miyazawa. (Knowing the prequel isn't necessary at all.)
