Apollo just stared in utter disbelief as he looked at Professor Adolfo, who was famously being called around the academy as a raving lunatic, though it was actually due to Mckenzie popularizing it to the other class. The man was a professional swordsman, he moved with a fluency and vigour one could only expect from a man who uses the weapon for a living. Apollo can tell he isn't just a random teacher, he is a soldier.
The evidence of this is the enormous body of the creature piled behind him. The huge hole depicted only the result of a single blow. What's even more funny is that the other professor only looked at the situation as if it was a normal thing to happen.
"Professor Adolfo…" The boy whispers, still unconsciously amazed. Behind professor Adolfo were professor Timothy and Alejo each holding their weapon. Moving his eyes further Apollo was able to see Professor Gelda and Agatha who aided the injured students and security personnel.
