All those pages just for cliche overused illusion dialogue? Geez, dude, have some variation will ya. If this stupid sword becomes MC sword, that gonna be suck.
They seem to be pushing that every Hero is inherently "Talented" and end up with self assured smugness and self-aggrandizement. So the idea of someone they see beneath them managing to defy them for this long in a martial combat is probably a personal insult.
In other words, the dude's being childishly petty to someone he- for all intents and purposes- should just see as a mysterious, "Talented" little girl. Though, probably also taking out some anger for killing that Knight dude he looked up to when he was younger.
