Senpai Noticed Me

                        "Mr. Okumura," You said walking up to his desk after he dismissed class.  He looked up at you with those intriguing teal eyes of his, the expression on his face placid. 
                       "Yes Persephone?" He asked as he stood up from his desk, tossing a semi-large satchel around his torso. "Is there something I can help you with?"
                     "I was wondering if there was any school work that you wanted me to be caught up on," You said, crossing your arms behind your back, "Im determined to do well in your class."
                     His eyes met yours again, then glanced towards the floor as he pushed his glasses up the curve of his nose. 
                    "There's nothing really that you can be caught up on," He answered curtly, as he stepped around his desk towards you, "but we should probably be getting you to your gym class don't you think?" 
                    "Oh," You said, looking down at the button up blouse and jeans you wore, "do you think that these would work? Or will I need to change?"
                   "You'll have to change," He responded after eying you for a moment. You didn't fail to notice how his eyes lingered on your slim waist and your well curved hips. "But I doubt you have anything suitable to wear in that purse of yours so-"
                   "Actually," You interrupted. Sticking your hand into the empty shoulder bag you carried, you quickly conjured gym clothes (of course you couldn't let him see your powers) and pulled them out, "Okumura-senpai I did bring a gym uniform from my last school if that's okay. I thought it would be best to be prepared."
                    Yukio raised an eyebrow at you, looking a bit impressed.
                   "Um, is there a place I could change really quick perhaps?" 
                   "Uh, er yeah," He answered, looking a tad flustered. He quickly stepped towards the door and out. "Change in here and I'll escort you to your next class." 
                    You couldn't help but giggle when he closed the door behind him. What a strange boy. Although you knew he was a half demon, he didn't have any of the normal traits. No pointed ears or sharpened canines. Nor did he seem to be arrogant or have gallons of testosterone pumping through his veins like the other children of Satan. As you unbottoned your blouse and slipped it off your shoulders you couldnt help but wonder if he was imagining you undressing. An evil smirk played on your lips as you let your jeans pool around your ankles. A very good "evil" plan had managed to pop into your head. Gently ramming your hip into his desk, you let yourself fall to the ground with a medium loud "ouch!". Making sure to hide your tail behind you. 
                   "Persephone?!" Yukio said, bursting through the door, his gun drawn. His face was completely serious until he noticed you sitting on the floor, your pants around your ankles. His face was enveloped in a bright crimson blush when he realized that you were indecent(only wearing your bra and underwear). But his deep teal eyes lingered on you much longer than any teachers eyes should linger on a student. Weakly covering your already lace covered chest with your arms you brought a bashful expression to your face and looked away from Yukio.
                   "Okumura-senpai," You said softly, making your face blush slightly, "it's embarrassing for you to see me like this." 
                   "O-oh! My apologies!" He said and swiftly turned around. When his back was to you you grinned widely. That worked out pretty well, you got to see him blush at least. And you were plenty satisfied with that, at least for now. Standing up with ease you slipped your feet out from your jeans. As you slipped on an athletic buruma over your panties Yukio spoke, this time in a calmer, more even tone, "Are you okay Persephone?" 
                  "Yes Senpai," you said with an innocent tone. After wrapping your tail around your middle and pulling a plain white t-shirt over your head you stuffed your other clothes into your bag and slung it over your shoulder, "I'm just a clutz I guess. I kinda rammed my hip into your desk and tripped. Don't ask how I managed that, I'm not even completely sure how it happened."
                   Walking up behind Yukio you tapped his shoulder. He turned and met your eyes for a second, his face still pink. 
                   "A-are you ready to go?" He asked, clearing his throat.
                   "Yeup Senpai, I'm all set."
                   "Okay, lets get you to gym class then." He gave you a nod and a slight smile. Yukio led you down a dingy hall, out into a court yard and then back into a large building. As you walked down another empty hall you could hear some yelling not to far away. Before Yukio opened a large door at the end of the hallway he placed a hand on your shoulder. "You don't have to address me formally when were alone Persephone-chan, when its just us you can call me Yukio." 
                     "Oh, okay," You said, giving him a bright smile. You placed your hand on top of his, which was still on your shoulder, "Thank you for walking me to class, Yukio." 
                    He smiled back at you and opened the door with a curtious swing of his arm. Taking a few steps in you waved a quick goodbye to Yukio, but the door was already closing and his back was to you as he walked away down the hallway from wence he came. 
                   "Persephone-chan!" Rin greeted loudly with an over exagerated wave. The closer you stepped, you could see more of a large in ground arena looking area. Two students which you recognized as Shima and Konekomaru were running around, with a leaper of all things bounding after them. Plopping down on the edge beside your more demon like half brother, you asked what was going on. To which he replied, "Just or normal exercises." 
                   With a bright smirk on your face, the teacher yanked down a lever and pulled the leaper back into its cage. Shima and Konekomaru climbed up out of the arena, each of them waving at you with tired smiles. 
                  "Miss Persephone," The teacher said, "since you were late, each of the others already went in pairs. Now I hate to put you on the spot but you did this to yourself, being tardy and all. You're going to have to do this all by yourself."
                   Although you could tell that the fool was trying to frighten you, you just grinned. You were too eager to hop up and slide down the slanted side of the arena. When your feet hit the dirt floor you smirked broadly at the ugly giant frog in the cage. There wasn't just one either, there were three all in separate cages. Egyn (demon king of water) had killed your kin before, a cat sith that you had become fond of. Now it was time for pay back. 
                  "Now you have two options here, kill the creature, if you can, or run from it for ten minutes, the choice is yours. Now don't worry, you won't be in any danger, I have complete control of the situation." 
                  "Bring it on," You said, a sadistic smile stretching across your face.
                  (~~~~Meanwhile, Out In The Hallway~~~~)
                   "You should really see her in action, she's quite something." Mephisto said, twirling his umbrella around his finger, "Her combat skills and strength are really the main reasons I handled her enrollment here myself. I think you'd find her interesting. Gym class would be the perfect opportunity for you to get a peek see for yourself. " 
                    Tapping his foot impatiently Yukio crossed his arms. He couldn't deny that you'd already caught his attention. Which in itself was something interesting, because not many girls could draw his full attention like you could. But if his boss, the chairman of True Cross Academy had a personal interest in you, it was either very good, or very very bad. He wasn't eager to find out which, but he needed to know. 
                    "Alright Mephisto," Yukio agreed reluctantly, sliding his glasses up the ridge of his nose, "I'll peek in on the class, but after that I really have to get back to grading tests." 
                   Yukio turned on his heel to head back towards the gym. If Mephisto really enrolled you soully based on your physical abilities maybe you had the potential to be a Knight or a maybe even a Dragoon like himself. The thought made the corner of his mouth twitch upwards slightly. He had to admit that he kind of liked the idea of working with you.
                  (~~~~~Back To You~~~~~)
                  "Alright," The teacher said, his hand on the lever, "Ready, Se-" 
                  "Just pull the damn lever!" 
                  "Go."
                  You were a bit too eager. Before the leaper even bounded out of its cage you jutted forward, dust kicking up behind you in a straight high line. Your eyes slitted and narrowed. Your few actions were too fast for the human eye to see clearly, but the half demons in the room could see you just a bit clearer. Running the sharp nail of your thumb down your forarm you grinned wickedly. Black smoke poured out of the wound along with blood, but it didn't fall to the ground.
                  "Shadow blade of the Darkness Knight!" You said with a booming voice. The smoke merged with your blood, forming a large rectangular shaped blade nearly three times your size and height. It was long and could be divided into segments that were connected by thick flexible wires. With one swing at the cages, you took out all three leapers (also cutting their cages in half during the process). Your movements had happened with in a few seconds. Standing up straight as you saw the creatures die, your smile became soft. Your familiar was avenged. "Release." 
                   With that one word, the sword disintegrated, the blood and shadows that had formed it returned to your open wound and sealed itself with a burning sensation. That technique took a lot of energy out of you. It usually left you a little wobbly for a couple minutes, and the cut on your arm would sting a bit, but the strength was worth it. Running your fingers back through your hair you glanced upwards towards where your classmates sat. Their mouths were agape, eyes wide, all concentrated on you. An egotistic smirk played on your lips, until your eyes met a pair of sharp teal ones. His eyes bore into yours, not burning, not smoldering, but simply observing with a noticible interest. You noticed one of his eyebrows twitch upwards and a soft smirk played on your lips again. Yukio had been watching you. You didn't know if his inferior eyes could follow your movements but he saw some of the damage that you could inflict. And you hadn't even been really trying. Stepping towards the ladder you could hear an excited voice as you climbed up.
                  "That was amazing!" Rin said with a look of aw on his face, "How did you do that?!"
                  "You moved so fast that I couldn't even see you!" The blonde named Shiemi chimed in with her big green eyes looking starstruck.
                  "Pretty impressive," Ryuji said to you with a nod and a pat on your shoulder. 
                  The small group of your peers gathered around you. And even though you smiled and pretended to listen to their words, their compliments, their questions, your eyes kept going beyond them to the brunet that lingered in the background. His eyes were trained on yours and a microscopic, almost nonexistant smile hung on his lips. When the class was dismissed and the excited group somewhat subsided you hopped up to Yukio with a soft smile. 
                   "Did I do well Senpai?"
                   "I thought I said you could use my name when we were alone." Yukio said with a soft sigh. "But yes, you did very well." 
                   "Thank you," You smiled up at him then looked down at the floor with a false blush and folded your hands behind your back. But then you giggled. 
                  "What is it?" He asked, looking a little surprised. 
                  "Senpai noticed me," you said with a soft genuine laugh. 
                  Yukio couldn't help but laugh too. Who was this girl? Catching his interest, catching Mephistos interest enough for him to enroll her here. Who was this girl that made him blush and laugh and impressed him? He didn't know the answers, but he was determined to find out.
