Well, how could he not charge?
Luca had been itching to test his hypothesis since the beginning of the exam.
While others might've assumed he was following Xavier's tactics, the truth was a little more niche. This time around, Luca hadn't actually been focused on Xavier's movements—what had caught his attention was the weapon and how Xavier used it.
Specifically, the custom ones they were asked to use for the exam.
Because no matter how he looked at it, this weapon felt different than their usual ones.
So he asked D-29 to look into it, and after a few scans, the little system gave a very telling analysis:
"Host, these weapons aren't fitted with limiters."
"Ah! That's why!"
And that was all Luca needed to hear.
