Okkotsu is a far stronger person than Kento, mentally at least, as he does not immediately unsheathe his sword and go for his teacher's throat.

The silence is omnipresent, Kento glances up briefly from his hands at Okkotsu's expression. He finds something almost too calm in it. Perhaps the shock has gotten the better of the boy. But apart from the slightly wide, almost manic eyes, Okkotsu doesn't look any different from the ordinary, polite boy he is.

With great deliberation, he can see Okkotsu putting his phone back into his pocket. Slowly, carefully, like someone who's trying to buy more time. He can almost hear the sound of Okkotsu's brain computing, running simulations in the boy's head as to how to respond to

that

particular comment from his teacher. A far weaker person would have collapsed, put his head in his hands, and promptly tried to dissociate until his mind landed in beautiful, scenic Malaysia.
