Jack thought that it was a good thing that Elijah wasn't a master swordsman.
But he feared what would happen if Elijah used the same determination he used in learning how to wield a spear to train in the sword, the results would be unlikeable.
As the battle kept on going, the more Jack had to restraint himself from using his magical power.
Even though Elijah was a tier 6 lesser ranked devil-like himself, he doubted that if he should use his magicraft, then Elijah wouldn't even be a match for him.
In terms of skills, he knew that he was lacking, but in terms of strength.
Sigh!!
He already knew that he had lost this match, but if there ever came a time when they had to fight to the death, then he would gladly see how Elijah skills could save him from his blade.
