You were a new member of the Port Mafia. Mori assigned Chuuya to be your mentor, meaning he had to train you and show you around the Port Maifia building.

Chuuya was in progress of training you at the moment. You had a dummy in front of you about 20 feet away and you had to hit it in under 3 seconds. Chuuya kept yelling at you every time you made a mistake. "How can you not be able to do this!? Even our lowest ranked members can do this!"
