Gramir reluctantly stepped into the ring and invited Zach for a duel.
It was Zach's first time fighting against a girl after fighting with Aria in her domain.
However, it wasn't as if Zach was planning to go easy on her just because Gramir was a girl.
Obviously, Zach didn't like killing anyone, especially the innocents.
First, Gildarts had tried to kill Zach, but Zach spared him after kicking him three times in the nuts.
Second, Ishajreon tried to kill Zach using the Mana Zone, so Zach left his life hanging on a thread, and fate willed him dead.
Third, it was Jeremy, who didn't do anything, but he was sent flying a hundred meters away by Zach.
Zach wasn't sure if he had died, but the duel ended.
Fourth, it was Razeir, who died because of his foolishness. If only he had surrendered instead of charging himself at Zach, the duel would have ended and the dagger's effect would have stopped.
