"How could she?" Toushiro thought.

It was one thing that got him in trouble and it was one thing that humiliated him but to put him through that? That was another matter entirely. Karin's love potion prank had been way below the belt and he determined to pay her back. It seemed like she really enjoyed her potion prank. Well, she wasn't the only person who could use the potion, he had a plan too.

He knew Karin didn't like kido class that much because she couldn't concentrate on the spells, just like her brother. So he enlisted the help of shinigami student from her class who had been accepting some easy assignments from his squad, Akemi. From his questioning, he found out that Karin had to learn new kido spell. So in the morning he equipped Akemi with a carefully selected potion that he got from the 11th squad and gave very specific instructions for its use

In class, Karin groaned loudly. Her kido spell wasn't going well at all. This spell was definitely too complicated for her and she was struggling greatly.

"Are you okay?" Ruka asked her worriedly.

"I'm okay." Karin replied trying to force a smile.

The truth was, she had just burned the wall behind her; there was a magenta smoke and a hole in the wall that she needed to fix before everyone in her class noticed. So she was frantically thumbing through her kido book, trying to find some spells that could fix it. She gave a loud cry of frustration when Akemi bumped her desk in passing, causing some of her books to fall to the ground. Immediately, she dropped to the floor to pick up her books and some of the lectures, didn't notice that Akemi slipped a handful of clear liquid into her bottle of water that was still on her desk and scampered away.

Finally, having recollected her books and her lectures, Karin rose from the ground and resumed her task. Unfortunately, the potion was activated; her bottle of water exploded with a loud bang and a large emission of smoke. When the smoke cleared and Karin emerged, coughing, she saw that her classmates were looking at her in disbelief. After a moment, the looks on the their faces turned from disbelief to pity and indignation, and some of them began to howl with laughter.

"Kurosaki, What's happened?" Her sensei bustled over to her desk and looked at her shocked.

"I don't know sir." Karin replied quietly.

"Clean up Karosaki," Her sensei told her. "Ruka, can you take her to the 4th squad? Maybe someone there can fix her up."

"Fix me up?" Karin turned to Ruka. "What is it? What's happened to me?"

"I'm really sorry, Karin," Ruka gave her a sad look as she handed her a small mirror.

Karin peered into the mirror and gasped. The end of her hair were singed and blackened, and she had a black mustache and a curled goatee.

"Toushiro," Karin snarled before had all her book packed away. Well, it made sense, didn't it? Akemi was the best student in her class, and many squads had been giving him small assignments to prepare him for the real job. And she knew he had been taking some assignments from the 10th squad, so this meant that he knew Toushiro. Plus, Akemi was the only person who touched her desk.

Karin hurried off to the 4th squad, hoping to get her new features cleared away before she had to face the whole Academy. However, to her great displeasure, Unohana taicho was unable to immediately clear away her facial hair, and there was nothing she could do to fix her burned hair. But she gave her a medicine and promised that everything would be gone by the next morning.

Upon arriving to the 5th squad, Karin slammed her bag down at her brother's desk, and of course, ignoring Rukia's, Renji's, and her own brother's shocked cries.

"What's happened?"

Karin didn't reply but set off in the direction of the 10th squad office. As soon as the door slid open, she placed her hands on her hips and began to tap her toe impatiently, waiting for Toushiro to notice her. However, it was his 3rd seat who looked around and noticed her first. His face split into an amused grin and he called his captain softly.

"Hitsugaya taicho."

"What is it, Ebisu?" Toushiro asked and looked his 3rd seat, but he was distracted as soon as he saw that Karin was standing in his office.

"How can I help you today, Kurosaki?" Toushiro sat up and walked towards Karin, trying to hide his infamous smirk.

"You did this to me." Karin hissed.

"Did what?" Toushiro asked innocently.

"This!" Karin cried gesturing at mustache.

"I don't see any difference." Toushiro drawled.

"Oh yeah?" Karin said. It was taking all of her self control not to punch him in the face.

"If you must know, I just wanted to manifest some of your personality traits as physical features," Toushiro sighed. "You know, to make it clear that you are, in fact, the devil personified."

"Watch your back, Toushiro." Karin snarled. She jabbed him in the chest with her index finger and walked away.

"Do you think it's a good idea taicho." Ebisu asked. "She is the sister of Kurosaki Ichigo after all."

"Just do your work." Toushiro spat and turned back to his desk to continued working on his paperwork.

...

Angry didn't begin to cover it. Furious didn't begin to cover it. Karin needed a whole new word to describe what she was feeling towards Toushiro right now. She was anxious for revenge, but what could she do that would really get him back for this? This was the question that she asked herself as she tried to sleep that night. However, both plotting revenge and falling asleep were easier said than done. This time, Toushiro had gotten her really good and she was forced to admit that to herself. It was hard to believe that this was coming from the 10th squad captain, and she knew it would be hard to top his action. Falling asleep was difficult because the mustache made her face itch. But she finally did fall asleep and when she awoke the next morning, it was gone and she had a plan.

The only remaining evidence of the explosion was Karin singed hair, but that wasn't a problem because she decided to cut off the burned ends. Now Karin, with her hair several inches shorter, got dressed and headed down to meet her friends in classes, anxious for the opportunity to put her brilliant scheme into action in the evening. Unfortunately, no such opportunity presented itself that day (though she did receive many compliments on her new haircut) Karin couldn't execute her plan the next day either. In fact, during that entire week, she was unable to get her revenge because she didn't have time to do anything but homework. However, she didn't mind this. It was a good thing actually because she hoped that Toushiro would be lured into a false sense of security.

Finally after two weeks and a half, she decided that she had waited long enough, and that she would take matters into her own hands.

"Ichigo?" Karin began as she walked into the 5th squad office. "Can I ask you a favor?"

"Depends on what kind of favor." Ichigo replied reluctantly removed his attention from Rukia who was sitting across the room.

"Could I borrow your map?" Karin asked tentatively. She remembered that her brother had to draw a map of the taicho residence because he got lost and couldn't find his place.

"What for?" Ichigo asked suspiciously.

"Revenge," Karin replied in a bold voice. "On Hitsugaya taicho."

"Oh," Ichigo replied thinking of what he saw when his sister burst into his office looking angry. "You don't have to call him Hitsugaya taicho in front of me, he is just a kid."

"Okay, revenge on Toushiro then." Karin smiled, figuring that her brother might be willing to help her.

"I'm always willing to help." Ichigo grinned. "Would you like to borrow anything else too?"

"No, thank you." Karin replied. "This is enough. I will be right back."

"Wait," Ichigo called. "What exactly do you have in store?"

"Oh, you will see." Karin smiled and smirked wickedly.

Karin decided to strike during the captain meeting because she knew every captain would be together in the meeting, and no one would interupt her plan. She left her classes early and slipped into the taicho residence section. Then, she pulled out the map in her bag to look for the Toushiro's place. When she arrived, she was a little exhausted. His place was hard to find even though she had a map in her hand. She burst into his bedroom and looked for his closet.

"You are going to pay for this, Toushiro." Karin muttered when she found the black uniform of shinigami folded neatly inside the closet. "I want to know what you are going to do if all of your uniform magically disappeared and replaced with something else."

Smirking evilly, Karin left. She was ecstatic. This was going exactly as she intended and she was feeling wonderfully triumphant. There was just one final step left; she had to wait until Toushiro found out what had happened to his uniforms.

...

"Matsumoto." Toushiro groaned as he was walking back to his residence to change into the new uniform before the captain meeting started. He was already late and it was his lieutenant's fault because she spilled sake on his paperwork and his uniforms.

"I'm sorry, taicho." Matsumoto spoke softly following her young captain. "I didn't mean to taicho, It was an accident."

Of course, Toushiro ignored her as usual. He walked into his bedroom and opened his closet.

"What the hell happens to my uniforms?" Toushiro couldn't do anything. He just blinked and stared inside his closet. His uniforms had been replaced by pink kimonos.

Matsumoto walked to her captain and look inside the closet. She immediately burst into laughter. Her captain with pink kimono. Oh, good choice!!

"She…," Toushiro whispered to himself, his voice shaking with suppressed rage, and his face was growing read. "She is unbelievable."

"She's got style, taicho." Matsumoto remarked while still chuckling at her captain's situation.

"Shut up, Matsumoto." Toushiro snarled and threw hot pink kimono at his lieutenant. "You can have it if you want."

Surely, that was the first time that Hitsugaya taicho, the captain of the 10th squad missed the captain meeting.

To be honest, I kind of regret using the love potion in the second chapter. Now it is hard to find something to top that chapter. Anyways, please review :)
