It's quite shocking how the quality of the first part of the first season differs from the second part. Some scenes have really bad animation out of nowhere, and it's unclear what happened there.
I gave the first season a solid 7. I think this season also deserves a 7, but not as much as the first. Some explanations about the characters become repetitive and take away from the excitement of the fight. Additionally, the fights don't have the same magic as the first part, except for the Kaolan and the last Fang fight.
The Kaolan fight is emotionally charged due to his opponent's history, and the Fang fight is quite funny. At first glance, I thought the fight was okay, but the grappling part was strange. However, after watching a channel called Scenec Fights, they review this fight scene, I could see the layers involved in the fight. Ohkubo repeats the same movement, and then Fang reads and counterattacks. The grappling part was quite realistic to the parameters of real MMA fights, which was really cool.
