After about 10-15 minutes, Sophia took charge, leading all the students in the battle and playing defensively, using all of her thousands of years of experience and understanding of human psychology to make the most of the fight.
Jaden, meanwhile, had been wracking his brain from the very beginning of the battle, from the moment Axel Nomrad had left the place. Revealing that hateful piece of information, which he had not yet shared with anyone. Nor did it seem like Nomrad had shared that info with anyone else. Likely not even the valkyrie herself.
Jaden had communicated with Heinz, Enrick, Thorian, and Sophia, learning of their most potent methods for countering death energies or taking down bone golems with efficiency and piecing those together, trying to form a plan, and considering all the possibilities of a massive counterattack using all the resources they had together.
