Extra Chapter 2.5; Arcade

Killua sighed, resting his head on the table as he tried to doze off. He was done rather early, considering that he had already studied the crap they were studying right now. He could feel the stares of his classmates on his back, and a smirk made its way to his lips as he recognized one of the feelings they gave off; it was fear. That was the look Killua loved the most. To see the despair, the look of horror, the fear on people's faces. Especially if it was caused by him.

Call him a crazy psycho, but Killua didn't care. It wasn't his fault that he turned out the way he is now. After all, a Zoldyck does go insane one day. Look at his mother; a crazy, psycho mummy. There's Illumi, too, who looks exactly like a girl and is a total manipulative bastard. Milluki, who's a disgusting otaku, and Kalluto, the cross-dressing idiot. The only person Killua wouldn't dare to insult was his precious little sister, Alluka.

"Hey, is it just me, or did Killua just let put on a rather adorable looking face?" His sharp ears immediately caused that, and without further delay, he quickly put up the most murderous scowl he could muster. "Aw, now its gone. I shouldn't have said that!"

Killua, annoyed, gave the girl a glare, which made her squeak.

"Oi, mind your own business," he spat, but Korosensei's tentacles patted his head, making him the target of Killua's irritation. Killua slapped the disgusting, yellow tentacle and rested his head on the table once again.

"Killua, we're going to the arcade today," Karma informed the silver haired shut-off boy. "Wanna join us?"

Karma didn't miss the glint in Killua's eyes when he said 'arcade'.

So you like games, huh, Killua? Looks like he won't re-

"I refuse," Killua stated bluntly, blinking blankly. "I don't like the arcades that much." Getting up, the boy swung his bag over his shoulder, and walked out.

Darn it, I so wanted to try out the arcade.

Karma just stood there, hand half closed and frozen.

"What the... Just what is that guy?" Nagisa arrived just in time, and as he saw his best friend frozen, he grew confused. So he poked the redhead to get a response, and sweat dropped at what answer he received. "He doesn't like arcades..."

There it is, the extra! I hope you liked it xD
