Two years ago, on the precipice of the Neon U17 training camp, a mysterious young coach arrived.
Byodoin Phoenix, No. 1 In the First Army, returned to the cliff, challenged the young coach, and was eventually beaten down the mountain. Falling into hell, he re-entered the depths of Asura Shinto to practice, and realized a new realm.
However, two years later, he was beaten down the mountain again despite being full of confidence.
"He is too terrifying. How can one person comprehend so many different dimensions? Even if I reach the end of the Asura Shinto and open the doors to other paths, I will still not be able to defeat him."
"The speed at which he evolves into another dimension is like playing. He is the number one monster in the tennis world in history."
In the world arena, this monster makes the world's top professional players tremble.
After being thrown into hell and defeated by him, some players began to turn dark and embark on an endless road of revenge.
