( Winning against Professor Mia? Dream on! )
I was not underestimating Professor Frey who is a Rank-S -. However, compared to her, Professor Mia is much stronger. It is already hard for Professor Frey to win against Professor Mia if they were of the same rank but Professor Mia has advanced to Rank-S - earlier than Professor Frey.
It wouldn't be weird if Professor Mia had advanced to Rank-S after all these years. If so, then the chance of Professor Frey winning is almost zero.
Rather I am worried about Hiro, Lisa, and others who would be the targets of Rank-Bs and Rank-As Dark Guild members.
I was not sure how strong they had become but according to the novel, most of them would be around Rank-C in this period of time with Hiro becoming Rank-B -. However, I could not be certain as they had been growing faster than what is depicted in the novel.
Even so, I didn't believe they were strong enough to defend against so many Elites of the Dark Guild.
