The first duel

Another student raised his hand to ask a question. She picked him, and he got up to ask.

"What about duels against different classes?" he asked.

"Well now, that's a good question. Duels like that are allowed, but the lower-classman must be the one who accepts the duel.

Such duels can't hold if the lower-classman refuses. But when the lower-classman challenges his seniors to a duel, they must agree to it and duel him," she explained the concept to them.

There were no more questions that day, and so, she spoke a little more on the rules and called it a day.

Immediately she left the class, before even the students could get up, the door swung open, and a group of third years, about six in number, walked in.

Their presence drew all the attention, as this was not where they were supposed to be. Silva, on the other hand, noticed the person he had fought during the exams, and he could tell what this was about from just a glance.
