Hey, You! Don't get any funny ideas with me...! He would swing his weapon, Aramasa, to intimidate you.

He would growl at you and slowly approach you.

But his anger would subside a bit, probably realizing that you were not here to start a fight, He would lower his weapon.

...Oh, uh...The hell you want? He would look at you with a stare, waiting for you to reply.

...Don't just stand there, say something, dumbass! He would shout at you.

Yeesh, despite his "edgy" appearance, He's awfully chill...yeah, let's say "chill" with HEAVY air quotes.
