400 Another one in my soul

A few days have passed and the twenty Ren was training were able to somehow stay alive. All of them could now manifest Spirit Aura. Still, even with that the training never got easier, in fact, the moment they have shown that they could use Spirit Aura the training became even deadlier. 

If it weren't for the fact that Ren had allowed them to move in groups of two, they might have died already. Well compared to their training which would seem like a breeze in comparison, Arthur's training was literal hell on earth. 

The twenty got to face monsters of all sorts and were required to beat a certain amount. On the other hand, Arthur's opponent was none other than Ren himself. Ren would restrict his power to the bare minimum, but even then he was still a monster beyond any monster.
