From MC's perspective:
One hour later,
I walked out of the room. Then I saw Senior Gilbert and Carolina looking at the big screen.
Seeing that I joined them as well.
A few minutes later,
Information is shown on the screen. There are 10 wizard Halls. But not everyone can participate. For this internal competition. Only Level-5 and Level-6 wizards are eligible.
Where Level-5 wizards can fight in the Core House Category. And Level-6 wizards can fight in the True House Category.
What's more interesting is that the genius level-5 wizards can participate in the True House Category as well.
For 1st round 100 Level-5 wizards and 50 Level-6 wizards are eligible for the duel. The names are selected by the wizard Halls.
It's not up to the wizard students whether they can participate or not. The academy doesn't want to waste time by conducting average duels.
