"Alright class, Over the weekend, you've got a report to work on." The class all collectively groaned at Yukio's words. The bespectacled boy teacher waited for his class to silence, before continuing. "You are all to select a demon, and write a one-page report on that demon. Write about the demon's appearance, its powers, its behavior, its Kin(unless its Kin is unknown), its habitat, its weaknesses, and the approved methods towards fighting them." After a moment's thought, he added, "And to any Tamers, no, you cannot study your own familiars. However, you are allowed to study someone else's."
"Um...sensei?" A certain blonde's hand went up. "Yes, what is it Moriyama?" Shiemi pursed her lips slightly, trying to think of the proper words. "Well, for my report, can I study Rin?" At the mention of his name, Shiemi's boyfriend looked up and over at her with confusion. Yukio thought about that for a minute. "Well, I suppose he does count as a demon. Alright, you may."
"Yes!" Shiemi clapped her hands excitedly. Weekend-long homework wouldn't be quite as bad if she was dating the subject of her report. Later that evening, Rin and Shiemi were walking to Rin's dorm, talking. "Shima and Konekomaru will be coming by later, they asked to study Kuro and Ukobach for their reports. But they're staying in the kitchen; we'll have upstairs to ourselves. Yukio's out on a mission for two days." Shiemi nodded. She had kept silent most of the walk.
"After Konekomaru and Shima had arrived, Rin went upstairs to look for his girlfriend, who had disappeared just before.
As he went into his room, he called out for her. "Shiemi? You in here?"
He was swiftly tackled and pinned to the bed, or that was the intention. With his demon strength, he quickly had them on the floor and himself the one on top of. . . "Shiemi, what are you doing?" Rin asked, confused as to why the blonde had him in such a position. Shiemi smiled surprisingly coyly. "If I'm going to study you, I need to have an in-depth analysis." Any further argument was cut off by Shiemi kissing him. As they quickly sank deeper into the kiss, her hands went to the buttons of Rin's shirt, working to shed it aside.
That night, and much of the next day, was devoted to some particularly intense "studying". And Shiemi was right, it WAS better than most weekend projects.
