Another day, and after having thoroughly thrashed the heroes under the pretense of field training where I placed them in the arena to face me, and beat them until they passed out, I've come to the teachers' lounge with the Saint.
I have matters to discuss with the Saint, and it was quite fun beating the heroes they didn't stand a chance because they couldn't use magic or weapons, only mana reinforcement.
Since that was the excuse I used, a supposed situation where they don't have time to use anything other than their bodies, experience, and planning to face the enemy.
And since the Saint was there to heal them, I could beat them as much as I wanted, after all, I have a much superior physique to theirs, and without the use of abilities, they don't stand a chance against a "killing machine" like me.
In the end, it's basic race limitations, humans will never be equal in general attributes to my race.
