The Challenging round as it name implies involves challenges between the students.
There are two types of challenges in this. The first one is the freshmen or the equivalents, which means the people who are in the Initial Stage of Divine Plane Initiation challenging the winners of the tournament.
They can come forward and challenge any of the students that ranked in the Freshman tournament.
However, it is clearly apparent that the winners are winners for a reason.
So, once these challengers announce their challenge, three people of the same level can come out from the audience and challenge them. Once the challenger defeats these three people, they can recover and finally fight with the winner they decided on.
The second type of challenge is simple.
The Grade 2 Seniors, who are in the Middle-stage of Initiation can step forward and challenge the winners.
