Because of the way that he had evaded the previous punch, Katsuro couldn't prevent them from falling over again. He also took the punch to his face. However he only did this because it would reduce the balance of the man trying to pin him down. WIth a swift kick to Greg's knee he could turn the tables around and pin Greg down instead. It was quite obvious that he wasn't going to just give up like last time. Katsuro properly secured his hold on Greg. "This is the wrong way to 'hit on someone' you know." Katsuro couldn't stop himself from making a 'funny' remark. Sure, Katsuro's speciality was shooting, but he was strong enough to be able to win a normal fist fight. He knew from their previous stumble that Greg was no lightweight in fighting either, however, it would not be easy to escape from his hold. Maybe it was lucky for Greg that Katsuro somehow couldn't get serious with fighting him. Later on he would surely ask himself why that was the case. Although right now he focused on upholding his hold on Greg and trying to estimate if he has calmed down or not.
