With a total of 6 episodes, the direct sequel of the TV series shows us Hayato competing in the 11th Grand Prix in 2016 to defend his championship. However, the pressure threatens to crack him when it is clear that Super Asurada is already trash of the past and his skills as a racer are lacking, as painfully demonstrated by the sudden return of Knight Schumacher (yeah, that's his name lol) to the Grand Prix.
As expected, I greatly enjoyed this series of OVAs, not only because the quality of the animation went up several degrees compared to the TV series (ALL DAT SHADING!), but because they portrait quite a few things from actual F1 races, such as how fast the development of racing cars is: Super Asurada was the most advanced car in the previous season. At the beginning of the next one it is already outdated by the performance of the cars of the rest of the teams. Fortunately, it gets upgraded to the Super Asurada AKF-11, although in order for Hayato to draw its full potential, he also has to grow up even more a racer, developing an inertial drift technique.
I think my favorite moment was in the 4th episode, when Hayato pulls off a totally crazy ski stunt that allows him to win the race. Similarly, the OST is excellent, so, if you liked the Cyber Formula TV series, this is a no brainer that you simply must watch.
