ChocoComa (Karma and Nirvana)

Karma glanced around Diagon Alley before stepping into the ice-cream parlor. She went and sat up at the bar, far away from any other customers. It was still break, thankfully, and she had an intense craving for some serious ice-cream.
But not just ANY ice-cream.
A waitress came up to her and asked her if she would like something.
"I'll take the most mouth-watering chocolate-filled thing you have. Just take everything chocolate, and put it on top. Everything." The waitress nodded and smiled.
"What would you want me to call this thing, if I put it on the menu?"
Karma furrowed her eyebrows and thought before breaking out into a dazzling grin.
"A ChocoComa!" The waitress nodded and went off to get the ice cream. Karma swung back and forth on the bar stool, her legs swinging beneath her and her feet barely touching the ground.

Nirvana walked down Diagon Alley, her eyes wandering from here to there. Being as distracted as she was, someone in a hurry knocked her into the ice-cream parlor. Her notebook went flying, and papers scattered everywhere.
Avoiding the looks from the snickering younger years, she picked up the stray sheets and looked around for her notebook. It was laying on the ground, by the bar stools.
A girl, obviously a Slytherin, was sitting in a stool near the notebook.

Karma looked up at the girl, cocking her head to the side. "Hi there." She said, swinging her legs happily. She smiled brightly as she pointed her wand and flicked it so that the girl's papers flew into the air and scattered around the place. "Hurry and clean that up."

She watched her papers go flying once more. Her eyes formed into slits and she wondered what was this girl's problem.
But instead, bit her tongue and just picked everything up again.

Karma turned back toward the counter as the bartender place her sundae before her. "Here's your ChocoComa, Miss Black." She said, placing the giant concoction before Karma. She handed her a spoon. "Dig in."

Nirvana watched as the waitress handed over the spoon to that monstrosity of a sundae.
Eyes twinkling, a sudden idea hit her. The Ravenclaw pulled her wand.
"Petrificus Totalus," she whispered, pointing at the girl.

"Protego" Karma said lazily, flicking her wand and deflecting the spell easily. "We aren't allowed to do Magic outside of Hogwarts, you know." She said between spoonfuls. "You could be expelled."

"Ah, well my apologies." There was a mocking tone in Nirvana's voice. She knew that rule, everyone knows that rule. A voice inside her head said she may have risked something pointlessly.
Yet, as annoyed as she was, she couldn't help but smile at the girl's utter disinterest in anything but that sundae. It was priceless.

Karma took another spoonful of the ChocoComa, her eyes fluttering in reverance. It was delicious, and had enough chocolate to kill an army of dementors. She smiled and turned to the girl, her spoon still half in her mouth. "How goes it, Stranger?" She was in a much better mood now that there were unhealthy amounts of chocolate in her. "Hop up here, I haven't seen you before, you go to Hogwarts?"

"Yeah, I'm a third year Ravenclaw. I don't believe I've seen you before either."
Seeing as the girl's whole aura was changed, Nirvana didn't hesitate in taking a seat besides her.

Karma shrugged, mumbling around her spoon. "I'm a Slytherin. Third year." She looked the girl up and down. She wasn't that impressive, so Karma was not impressed. "My names Karma. Karma Black."

Her eyes widened as Karma said her last name.
"I'm Nirvana. Nirvana Remilda...Black."

Karma looked the girl up and down once more before snorting. "If you say so." She didn't believe her, that was sure. There were too many Blacks popping up out of the woodwork for her to believe all of them.

The snort made her disbelief evident. She could see why Karma wouldn't believe her. Karma's never seen her before. For all this girl knows, Nirvana could be lying through her teeth.
But whatever. It didn't make a difference to her whether or not she was believed.
Nirvana stood up.
"So, I guess I'll see you around."

Karma nodded and waved her hand dismissively. "See you at Hogwarts."
