Ai pressed a can of cola to her lips, condensation dripping down her fingers. She wiped her lips with a muscled arm and snapped the small metallic tab off the top of her cylinder.

"Ai." Yukio broke through Ai's heavy concentration. Her head pricked up and she glanced around in a very confused manner.

"Huh? What?" she tossed the tab inside her can, making a loud clanging noise. Ai jingled the makeshift instrument a few times before smiling absentmindedly and tossing it into a nearby trashcan.

"Would you take a seat please?" Yukio grumbled. He wasn't fond of people disrupting his class. Ai nodded, but remained at the front of the room. She sat down on the worn stone floor, placing the mysterious case she toted about before her. Heads pricked up as she popped open one of the fastenings and dipped down when she clicked it shut. Everyone was intrigued by the container, but not as much as Rin. The red spots on his fingertips had festered not only physically but also mentally. Blue fire came from his hands, yet the touch of a young girl left him pained and dazed. That didn't make any sense to Rin. He sat next to a young blonde woman in a brightly dyed kimono and glared at Ai with his sinful sapphire eyed. Ai shot him a perfect smile, that of straight teeth which maintained a color fairer than snow, and winked her eye of polished silver.

"I don't wanna!" Ai complained, clutching her luggage to her chest. It was strange to see such a small girl hold such a huge case with ease, especially when she swung it around.

"You'll have to. But as long as I have you up here, you won't be permitted to carry that around unless you have a valid reason." he pointed to the pitch black container on Ai's lap. A big smile spread across her childish face and she nodded. Ai dropped it in the center of the room, waiting for all her new classmates to gather around. Murmurs broke throughout the few people in the schoolroom but Yukio's presence calmed them down a bit. The only two who didn't go over to see happened to be Rin, who had a horrid feeling deep in his chest about Ai, and Shiemi, who was scared that if she went over Ai might not want to be her friend for some reason.

"Gather round, gather round! A valid reason is to be found!" Ai sang. She snapped open a single fastening at first, watching a glimmer of pure white dribble out. Then came the second, and the third, and, after quite a few more, came the twentieth. A divine light shone from within it and Ai smiled. She tugged the case open as slowly as possible, more excited than anyone else in the room. Ai reached inside and pulled out a viola the same color as her single sterling eye. Its lustrous shimmering body provided a wonderful place to rest one's chin while creating music. Ai drew a bow and stood. She pressed against the fingerboard delicately after tuning her instrument meticulously. The sound of rampant fiddling filled the room suddenly. Ai's fingers drifted up and down with sizzling precision, creating a tune that bounded through the ears of every student in cram school.

Rin's burns began to throb along with his temples. He pressed his head into the desk, frustrated and hazy.

"What's wrong?" the young blonde next to him inquired with genuine concern.

"Nothing..." Rin growled. He was normally much kinder around Shiemi but with a splitting headache of his degree, even the dim lighting of the old schoolroom caused searing pain. Ai put on an evil smile which showed her satisfaction in it's simplest form. She knew just how Rin felt. She knew she could stop it, and she knew she wouldn't. Perhaps she could be persuaded at some point, however. But for now, she was howling a rowdy song for the whole world to hear. Ai stomped her bare feet against the ground and even began a strange jig. There was a light rustle from beneath her shirt but it settled quickly.

"Why are we listening to her play the violin instead of actually learning something?" Izumo snarled. Ai drew her bow down so sharply both it and one of the golden hued strings snapped in half.

"First of all, it's a viola, smaller and better than the violin. And second, you keep your purple haired mouth shut about my playing." Ai roared. Her tank top bristled in a strange way, as if she held something beneath it. Izumo stood completely still with her arms pressed against her sides and her legs held together tightly. She appeared to be frozen in place, the only movement being the rising and falling of her slender chest. Rin managed to pick his head up so he could see what was happening. Ai stopped down into a sitting position and placed the viola back in it's case.

"What did you do?" Suguro poked Izumo's cheek. She would have swatted his hand away furiously in any other case, but the thick browed girl did nothing.

"When I'm angry, my string snaps, when my string snaps, that has adverse affects on humans around me, once my string is repaired, Izumo will be released. This is my weapon for taming demons, if you have any need for valid reasons this case contains my inhaler, retainer, and blood sugar monitor." Ai heaved the case onto her back and sauntered from the room.
