A/N: Changed the end of this chapter slightly as of 5/18/14. It might be worth glancing over the end. Sorry.
Sasuke leaned lazily against a desk in room 204, arms folded across his flak jacket. The rays of the Konoha sun shone in through the now open blinds. His would be students stood stock still before him, eyes wide and unseeing stared directly ahead. The buzzing of a fly continuously ramming a window seeking a way through the invisible barrier and the far off laughs of some genin below were all he could hear. The idyllic nature of the seen was set in stark contrast with what he knew the three genin were currently experiencing within their own minds.
Some might say it was cruel what he was doing to them. Maybe it was. But Sasuke knew if he could handle the very same experience when he was years younger in reality then they should be able to survive a watered down genjutsu version of it. If they couldn't. Well they wouldn't last very long on his team, let alone in the ninja world, even one at peace.
The first body Gin saw in the darkened room was his sister's. The person he was closest to, cared the most for was slumped lifelessly on the ground a pool of dark blood settling around her. He screamed her name. "Raimei" over and over as he ran over to her body for what felt like an eternity. Her throat was slit in a jagged line, her silver hair, the same shade as his own, was stained red, spread around her head like a pinkish-red halo. He knelt down beside her, cradling her body. Now he too was covered in blood. He yelled and cried and hugged her limp form for some time before finally noticing other strange things.
Some distance away he saw the girl who he had been teamed with screaming and crying and clutching what must have been her own murdered loved ones. Uchiha Yuu was nowhere to be seen. Then he noticed the bodies of his parents a few feet away. That was when he realized. He cursed. His parents wouldn't be killed that easily, not the two of them together. This was genjutsu. He remembered the sign for breaking a genjutsu. He squeezed his eyes shut and with a shaky hand made it yelling "kai". He hesitantly opened his eyes. The gruesome scene in the darkened classroom was still before him. He muttered and yelled "This is genjutsu. It has to be. This isn't real." He tried again and again found no success. "This is not real!" He thought about his mother and father and sister and their laughs and smiles and dreams. He tried again.
Gin blearily snapped to reality. The sun was shining directly in his eyes. He immediately dropped to his knees, ducked his head, and threw up. Tears stung his eyes. He cautiously glanced over to his right. Yuu was beside him in a similar state. He noticed a bloody kunai sitting beside him and a puncture wound on the boy's thigh just above his knee. So that was how he broke free. The pain brought him back.
It was when he attempted to stand, with no small degree difficulty, that he noticed his other teammate was still standing. She was completely unmoving, like a statue. A vacant, dead look still claiming her eyes.
Once he and Yuu managed to stand they finally took notice of the other man in the room. The one undoubtedly responsible for the cruelty they had just experienced. They both recognized him, though neither knew him personally.
"Uchiha" Gin had started to say but Yuu finished, "Sasuke."
Gin was livid. "You're supposed to be our sensei?!" he cried, "What the hell was that about you bastard?!"
Sasuke smirked. "Really I'm surprised you two managed to get out at all." Admittedly he really was surprised when the first boy broke free. It was Yuu. And although he was in there for some time he was still the first out. Sasuke nearly choked when he saw the boy start to move, shakily grab a kunai from his pouch and stab it into his own thigh. It was something he would have done, something he had done in the past. But he hid his surprise well. He glanced at the girl, Himura, she was still in her own personal hell. The boys followed his glance.
Yuu spoke, "So what are you waiting for?" he asked, his dark eyes meeting Sasuke's swirling Sharingan which maintained the genjutsu on the girl.
"Yeah" Gin added, "Let her go."
Sasuke shook his head. "I don't think so," he smiled, "She should get out of it herself. If she wants to play at being a ninja she will have to deal with the consequences."
"You're crazy!" Gin yelled, "Do you know what the fuck she's going through in there?"
Sasuke laughed. "I know exactly what she's feeling, what you felt, and I lived through it a hell of a lot longer."
"She's not you, you bastard!" Gin made the sign to release the genjutsu, "If you won't let her out, I will." Nothing happened.
Sasuke raised an eyebrow incredulously, "You think a genin saying 'kai' and making a hand sign can release a jounin's, an Uchiha's genjutsu? I expected more from Kakashi's son."
Gin looked down and grit his teeth.
Yuu met Sasuke's eyes again. "I think—she'll really be in trouble if you don't release the genjutsu. We—she's just a kid."
"Is that the best you can do? Say she'll be 'in trouble'? Seeing your dead loved ones over and over again and being able to do absolutely nothing to help them hardly does wonders for anyone's mind, a weak little girl like her, if she doesn't break free soon she'll probably lose it"
The two boys were at a loss. Both knew the theory perfectly. A sudden surge of chakra could be used to disrupt her own flow and break the genjutsu. Both also knew such a skill was not one possessed by a genin.
They stood their ground in silence for the better part of the next hour until she seemingly passed out, collapsed in a sad heap on the floor.
Sasuke chuckled and started for the door casually calling, "She should probably see a medic," over his shoulder and leaving. Neither boy realizing that it was in fact Sasuke who released the jutsu, bored with the failures of his young charges.
A few moments after his departure the imposing figure of an Anbu operative was upon the children, much as Sasuke expected there would be.
The mysterious, cat masked shinobi ordered the boys to return home and took up the crumpled form of their teammate. Eying the hesitant looks of the boys the Anbu responded, "She'll be fine, go home."
Exhausted after a morning of psychological torture they heeded the orders and silently parted ways, both wondering what it would be like on a team like this.
