Plane Killer.
After Nana's death, the demons hidden away in various shades and corners did not dare to make a move. Lenny had achieved the impossible. Nana had hunted people for even the royal families for a long time, and no one had been able to bring her down. Yet Lenny had done so effortlessly. As such, all those in hiding knew he was not one to be messed with.
Lenny returned to his experimentation, dragging Nana's body behind him. He intended to incorporate it into his work. Meanwhile, the crowd in the stands also looked at him with newfound respect. He was like a dark horse that had emerged from nowhere.
This round of the competition took another two days to conclude. Some battles lasted for hours on end, but none came close to Lenny's display of power and skill. Finally, on the second day, an announcement was made that this segment was over.
