Naruto NB 1: Training Day

Raiko and his two team members Z ans Enzeru, wait for ther sensei to arrive at the training ground. Raiko sits under a tree, resting up, while Z and Enzeru have one of their famous arguments.
Z: For once, can you not be such a snob!?
Enzeru: I'm not being being a snob! Why don't you stop being such a jerk!?
Z: How am I being a jerk? I told you not to use my weapons as a mirror or snipping you hair! Yet, because you think you're so much better than everyone else, you went ahead and used it anyway.
Enzeru: Hey, I forgot my mirrior at home. Besides, you weren't using any of them.
Z: That's not the point!
There argument was loud enough to wake Raiko from his sleep. For a moment, he didn't know what his two comrades were doing, but once he could hear fully, he knew what was happening.
Raiko(sleeply): Geez, you guys can't stop fighting for more than a day, can you?
The two stop arguing for a moment and Raiko walks over to them.
Raiko: Instead of fighting, you shoild be paying attention to something more important. Sensei just arrived.
A man, dressed in mostly black, was leaning up against an oak tree, was staring at the three Genin. His gaze was hard and cold, and Raiko an his friends could tell that he wasn't happy. So, they decided that the smart thing to do was to run over to him, because none of them wanted to hear their sensei yell.
Raiko, Z, Enzeru<simataniously>: Good morning, Matsu-sensei
Matsu rolled his eyes and turned his head away from his students. The three friends looked at each other with the same confused look. Z steps foward a few steps.
Z: So sensei, are we gonna do somethi....
But before Z could finish asking, Matsu-sensei lunged at Z. His fist was winded back but before Z could even react, Matsu-sensei thrusted his fist foward and struck Z in the stomach. Z flew back a couple feet and skid back even more. Raiko and Enzeru stood there, shocked.
