Rengoku is standing at the center of the training room, sweat dripping down his face and chest.

His muscles are tense and his breathing is heavy, but his eyes are bright and his expression is fierce. He's just finished a particularly grueling set of exercises, and he feels a surge of adrenaline coursing through his body.

He takes a moment to catch his breath and then he lets out a loud yell, signaling his satisfaction with his workout.
