Here's the next installment! Enjoy!

The Week Before -

Karai hesitated outside her father's throne room, one hand resting on the handle. She hated this room; it was always too dark and cold, and she didn't appreciate her father sneering down at her from the shadows. Her grip tightened on the knob, and she took a deep breath before swinging the door open. She blinked, doing her best to make her face impassive, and she swaggered in to the middle of the room, bowing down on one knee.

"Karai," her father boomed. She met his gaze, two glittering eyes in the dark.

She bowed her head. "Yes, Father?"

"I have received word that the Turtles have an ally on the surface," he said, and she jerked her head back up.

"Have they infiltrated us?" she asked, and he laughed coldly, mockingly. She ducked her head again, and he continued. "You have a new assignment. You will be spying at the nearest public high school for the Purple Dragons. You need to seek out the Turtles' ally and befriend them, earning their trust and getting information."

Karai blinked, not sure she heard that correctly. "School?" she said, her impassive look cracking. "No way you're serious! Can't you send in the Foot soldiers?"

"You will," he replied, in a tone that spoke no arguing. "I do not have as much faith in the average Foot ninja as I do in you."

"But-" Karai started.

"Enough," The Shredder said coldly, helmet glinting. "You are dismissed."

Karai stared up at him, mouth hanging open. "I understand." She shut it firmly and nodded, straightening up and stalking out of the throne room. She threw open the doors, and the Foot ninja on guard out front jumped, hastily scurrying out of her way.

School? she thought to herself, scowling. What the hell am I supposed to do at school?

Present Day -

"Karai," April repeated, tasting out the name. "That's a nice name."

"It's Japanese," Karai replied shortly, looking at the her nails.

April's eyes lit up. "I have some friends who are Japanese," she said. Karai looked at her with one raised eyebrow and didn't bother to respond. April felt her cheeks begin to flush, and the awkward silence continued.

This is already sucking my will to live, Karai thought to herself, trying to ignore the girl - April, she thought with a sneer - and her rude staring. She mentally cursed the turtles for getting her into this mess.

"Karai Oroku?" The secretary called out. Karai looked down her nose at her, and the secretary's smile dimmed slightly. "Here is your schedule and locker combination. Right now it's homeroom, so your teacher will give you a rundown of the day when you arrive." Karai nodded and took the offered schedule, staring down at it. The secretary tried again, "It is always so nice to have an exchange student. I hope you have a good day!" Karai pressed her lips into a firm line and walked off.

The secretary looked a little flustered at Karai's lack of response, and she straightened up some things on her desk, face falling. April felt a little bad for her, so when she looked over at her, April gave her a nice smile. The secretary returned it. "April, you can go back now, too. And don't worry, I'll take this one off your record."

"Thanks!" April said, feeling her smile grow. It was a good thing she never got around to texting Robyn in the first place. She decided to go hurry and catch up with Karai, but when she turned the corner, she was already gone.

Huh, April thought, a little disappointed. Maybe she runs track or something. She trudged down the hallway, dreading going back to Hoffman's classroom. She walked as slowly as she could, rounding another corner and skidding to a stop. Karai was standing in the doorway, practically being interrogated by Ms. Hoffman. Karai barely spared her a glance, but Ms. Hoffman turned and looked at her with an annoyed expression.

"Look who finally decided to show up," Ms. Hoffman said, unimpressed. The class snickered as she stomped to her seat, sitting in her usual spot next to Irma.

"I hate that woman," she muttered to Irma, sinking down in her seat and avoiding her classmates' stares.

Irma snickered, pushing her glasses up her nose. "Don't worry, she obviously hates you, too." April made a face, and Irma's expression shifted slightly.

April narrowed her eyes. "What?"

"Well aren't you going to tell me why you had to bail on me again last night?" Irma said, and April mentally groaned, wanting to slam her head down on the desk. "Was it your new group of friends again?" She sneered on the word friends, and April flashed her an annoyed look, not in the mood for this conversation.

"Yes, actually, it was," April retorted. "Don't have to be so jealous, Irma."

Irma snorted, playing with a lock of her hair. "Yeah, and I have plenty of other friends. I don't have to hang out with you."

April blinked, feeling a little hurt. "Fine!" she snapped, feeling her hackles rise and getting defensive. "Then go hang out with your other friends then!"

"Fine!" Irma snapped back, hurt flashing across her eyes before it was replaced by anger. "Maybe I will!" She gathered up her books and marched over to the group of girls sitting on the other side of the room. That welcomed her in, scooting to make room for her, and all shot daggers at April.

April wanted to hit something. This just in; worst. day. ever. Irma smirked at her from across the room, and she scowled back. She felt someone poking her arm and whipped around.

"What?" she hissed.

"Look, sheesh." The boy behind her didn't even look phased. He just pointed to the front of the room, where Ms. Hoffman was standing with her arms crossed. Karai stood next to her, a bored look on her face.

"Are you with us, April?" Ms. Hoffman said, a slightly sarcastic look on her face. She shook her head, and Ms. Hoffman sighed. She pointed to Irma's now-empty seat. "You can sit there for now. I'd offer you a better seat, but there are no other open spots." April's scowl deepened, and she heard Irma laugh loudly from the other side of the room. Karai walked over, setting her things down.

April thumped her head down on her desk as the bell rang for first period. Karai looked up at the ceiling with a look of disdain, sighing as she picked up her things again. "I hate school," she muttered under her breath.

April snorted, and Karai looked at her with a raised eyebrow. "Get in line."

By the way, in this AU, Irma is human. R&R!
