Lifespan
Elorin's movements and stances were practically impossible to keep up with. He didn't seem to have much functional skill in combat, but when it came to the use of his Ability Index, he was simply on another level.
Leonel thought that maybe he should train Elorin in a Weapon Force, or maybe teach him some martial arts, but after a moment, he scrapped the idea. In fact, he felt that things were just fine like this.
During all these years, Elorin had been basically being trained by Anastasia. Anastasia's understanding of Time Force was probably comparable to even the most ancient ancestors of the Pluto Race. However, because of the failure of the Minerva in "creating" her, her thought processes and flexibility were limiting in combat.
