20 warriors?
From MC's perspective:
The result of the duel slowly reaches everyone's ears. When the warriors in the A grade heard about it. They weren't surprised.
They thought, If such a strong warrior existed in the B-grade institution then the person would have entered here long ago.
After this incident, many thought that the episode would come to an end.
But people in the B grade area are thinking about something else. Amelia is actively discussing with other faction heads to write the names of listed students.
Though Thomas's defeat was a setback. No one thought Zack could win easily without using the element.
Which made most of the warriors give up. Even for fun, they have decided not to bring up the topic of challenging Zack.
As the faction heads are discussing in their meeting room. Dean Rebecca called them. After knowing what's happening. She decided not to stop it.
