Delusions
Calculations quickly happened inside Khan's mind. His first instinct was to dodge Ilman's attacks until a professor arrived. The Niqols was fast, but Khan was faster, and his stamina was incredible. His mana capacity seemed even above that, so that approach was theoretically doable.
Yet, that tactic could only work if the professors decided to rule in his favor. Moreover, Khan would still need to dodge attacks for a bit more than an hour. He could probably do that with his speed and battle experience, but he wouldn't be able to avoid ending up in poor condition.
The Lightning-demon style gave Khan exceptional speed, but it was also an aggressive martial art. It expressed its true potential only when attacking. Relying on it only to dodge and run away would force him to ignore more than half of his techniques.
