Baki the grappler manga recently got a new adaptation by Netflix. Because I enjoy sports manga, I did not doubt to dive in and expected story like hajime no ippo.
It was not like hajime no ippo, While ippo still realistic to some extent, Baki is filled with fantasy and told in a fun crazy way. Just after watching the first  few episodes, I was impatient and went through reading the manga it was based on in one go. The manga is created by Keisuke Itagaki and now have been told over three sequel, with the latest one titled baki dou.
the story of Baki follow the story of Hanma Baki the son of the strongest person on earth Yuujiro Hanma. In addition, to overcome him he has to face many opponents in a tournament and in general. It was based on real fighting technique, but it was by no means real.
The movement of the technique and the impact of each hit are expressed very well by the unconventional arts. As you read through each series you will notice that the arts improved quite a lot, and you may not recognize the same character because they look so different (especially if you see the old anime adaptation).
Some people are experts at using karate, judo, taekwondo, and boxing. Some are using brute strength, and there are some that is compensating their technique with weapons, or underhanded tricks.
