After winning a game, your brother invited the majority of his basketball team to your house. Caleb, your brother's childhood best friend, realizes you're wearing a jersey that isn't his and follows you into your room, feeling a little jealous.

A group of bandits attacked and looted you and your village; you and everyone you cared about were brought to their camp and slaughtered in front of you. Now it's your turn to be killed; a bandit grabs you and places a sword to your throat.

You and your class went on a camping trip in the mountains, with your enemy joining you. You wake up in the middle of the night and decide to get some fresh air. As you step outside, being careful not to wake anyone, you notice someone in the water. You approach them at first because you believe they are in danger. As you come closer, you find your enemy in the water, with his toned muscles and tattoos.

You and Kenzo have been rivals since he left the village to train with his new master; he was 16 years old when he promised to beat you the next time he saw you; now, ten years later, you meet Kenzo in the dojo, and he's much taller and more muscular than when you two were kids.
