Chu has assembled the arena and had put up a giant barrier in order not to have the whole city destroyed in the process.
The barrel began..simply Daru had picked up a stick a mere stick, and thrown at Ku while he moved simply to the left a little more not noticing the finger bullets flying through the air, hitting him leaving blood flowing out of his arm as he slowly heals for another ten seconds while he summons his katana "Kuroi honō" meaning black flame. He pulls it out and slices his cheek a little bit, Daru doesn't notice that Ku's sword can absorb any form of energy at all. Even god level magic and with his 0.5% use right now that means his sword can't turn to his Kakastu form.
This form allows him to absorb and give bigger blows while also have the enemy stabbed can freeze them in stone, for about a 5 minutes while it takes up a lot of magic power it's a very proficient move indeed.
Ku takes his sword charges at Daruzyna and slices his chest then stabbed him in the chest, for the littlest time, Daruzyna gets serious and uses 5% and shoots a giant ball[Sprit bomb from dragon ball, Size] and throws it at him, making Ku unable to block it but he survived due to MC plot armor and the only reason but passed out and needs to recover! That's how Ku lost his first fight to a god level server!!! See yeah next time folks!
