[A/N: By the way, a little note for those who are confused by the fact that Aestrea is so strong. You should know that his Mana Quality, and density, are SS+, basically on top of the world, not to mention that he also has a special mana constitution that amplifies his mana output and input by ten times!
So even though his mana is classified as B-rank (because of his poor quantity), it's much stronger than that! It could even rival that of a high ss-rank mage, but of course, Aestrea would lose against one because he doesn't train magic spells and because the quantity of his mana is pitifully low. Not to mention, that he still didn't use his Aura.
So yeah, I hope that I clarified everything.]
The Death Tournament is an underground fight competition that happens every three months, hidden from the public eye.
It's pretty simple, really: sixteen challengers are chosen by the powerful figures in the underground world.
