Underneath the arena, the contestants were all busy getting ready for the fighting event. The weapons and armour they had hidden until now were all out on full display. Even if one was to see what their opponent was wearing, there was too little time to try to come up with a countermeasure. On top of this, the participants themselves did not know who they were going to go up against.
Students for this event were also able to use whatever equipment they owned. It didn't matter whether one person had higher gear than the other. It was all about individual strength rather than skill. The focus was to show how they would compete out in the real world.
