However, this kind of challenge is not something that can be undertaken at any time. According to the academy's regulations, no challenges are allowed during the first year. After the first year, a student may only issue a challenge once a month, and they must challenge in ascending order without skipping any levels.

Not only that, once the challenger defeats the challenged, the defeated has a week to retaliate. During this week, they can initiate a challenge every day, totaling seven challenges. If they win any one of these, then the challenger's attempt is considered a failure.
