A/N: Hahahas. I came up with this randomly and just had to post it up immediately so I don't think it's very good... But anyway, this chapter is dedicated to NinaKerndall for reasons she would understand. ;)
Natsuki ran into the classroom, banging open the door as she did so, giving everyone a fright. She was in the same class as Tsuna and co. Walking randomly up to Gokudera, she cried, "Goku-chan!" Gokudera immediately turned [insert angry expression + shade of face colour which is suitable here] and hissed, "I. Am. Not. A. Girl."
"But Goku-chan sounds so much better than Goku-kun!" Natsuki reasoned using not very reasonable reason which is reasonably reasonable enough in this reasonable or not-so-reasonable case.
Unable to stand this any longer, he took out his bombs but was stopped by Tsuna.
"We're in a classroom," Tsuna reminded him. Everyone else was noticeably not noticing the very noticeable commotion they were causing. Natsuki laughed, knowing that Gokudera could not take his revenge just yet. Even if he could, she could just dodge his bombs anyway. Besides, she could always call Bianchi to help her.
"Haha, what sort of game is this?" Yamamoto was rather curious.
"A game where you annoy everyone else!" Natsuki replied brightly. Tsuna and Gokudera looked at each other. She was obviously high on sugar that day.
Natsuki ripped out her rubber band from her long black hair and surprised everyone by pouncing on Gokudera and tying up his hair which was conveniently shoulder-length.
"Thank goodness you're only 160 something cm tall. It's very convenient to reach your hair, and you look even more like a girl now!" Natsuki gasped before curling up into a ball on the floor, laughing so hard until tears came out. (I won't describe Goku-chan's face there, it's rather…imaginable.)
Natsuki suddenly ceased her laughter and sat back onto her seat as if nothing has happened. Tsuna turned and saw the teacher stepping into the classroom.
Gokudera's yawn was cut short when a crumple piece of paper landed in his mouth. Fortunately, he did not choke. He looked to see Natsuki laughing silently, clutching her stomach. She looked at him with eyes that said, What nice aim I have!
The paper screamed "GOKU-CHAN!" when he opened it. Gokudera fumed silently. "She's definitely getting it," he hissed to himself.
Natsuki smiled to herself. Gokudera's fun to annoy, especially since he's so easily annoyed and he could not get his revenge right now. She'd have to prepare herself for later, though.
