10 years after the tower competition..
Many things had changed over the years, Axel was currently 25, while Akon was 20. After Axel had created the cure to the cancer, he had personally cured Rugen and many more innocent people in the city of Delmar. Unfortunately, the procedure of the cure was quite complicated and only Axel is able to perform it.
And he alone could not cure everyone, so every 6 months, he could cure a certain number of people at once. He didn't care too much about them, but a part of him still wanted to help them nonetheless.
Rugen was shown to be extremely talented in the Berserkers path and he was born with an extremely unique physique, the kid was already a 3 star berserker, and strong enough to handle multiple of those in the same level. Even fight against a normal 4 star warrior for short while using his secret technique. Rugen had actually become the direct disciple of the vice lord of the Berserker sect.
