Perfect. Chikusa isn't a sadist, generally speaking. There's no pleasure for him in the act of tormenting another person. It's just something to do, something that occasionally needs to be done in order to gain information or send a message.

But with Add....? For Add, he'll make an exception, and gladly. So he keeps his fingers locked in tight against Add's hair, watching him choke with a desperate trembling throat and as his body jerks violently with no control available. Now that's a reaction, isn't it? Watching his eyes spasm from the pain, mouth gaping for air....

It's just his luck, however, that he doesn't get to enjoy the sight for longer. As the air floods blue, Chikusa digs his fingers in just in case- but no. He knows what this is. Patiently, his foot still grinding down into Add's knuckles and his fingers fisted into Add's hair. He waits until Add has stopped convulsing so hard, and his eyes can focus once again.

"You used that before," he notes, "when fighting Ken. It brings you back.... doesn't it? Properly..." So that Add knows that he can't use this kind of trick and expect it to work so flawlessly. This won't be like last time, this won't be Ken. So, roughly, he shoves Add hard enough that he rolls onto his other side.... but his foot keeps his arm stretched out in place. Uncomfortable, stretched to the fullest length... so that when he stands up, still bearing his weight down on Add's hand, he can use his other foot to stomp down on his elbow as hard as he can.

Time to see how much force it takes to break Add's arm.
