If I had to pick a word to describe this story, it would be SIN, or crack taken seriously . Please review if I should continue.

"Have you cut your hair?" Nagisa's mom screamed in his face, going red with rage.

"O- only a little. I-It was getting hot in the summer." He whimpered. He didn't think his mother would notice that he chopped an inch or two off, he didn't think it was a big deal. But to his mother, it was. She grabbed a fistful of hair in her hands and dragged him closer to her.

"Is this really how you intend to treat your mother!?" She screeched, her face contorting into a mask of pure rage. She was livid. Nagisa felt his hands start to shake- He had to calm her down somehow! Even though he was strong enough as an assassain to easily defeat her, he was still felt he couldn't do anything, he was at her mercy.

"I'm sorry! It'll grow back! I'm sorry so please calm down." He whimpers, but his mother was relentless. She raised a hand and slapped him hard across the face.

"You insolent little- "

"Mom, please! I have to got to school!" Nagisa cried. He didn't dodge her strikes though even though he could. He was frozen in fear. She hit him again and again, his face erupted in pain, his cheeks stung and his eyes watered.

"If you EVER disobey me again!" Hiromei yelled, giving Nagisa a final push with all her strength. It sent him hurtling back into the kitchen table. he tried to stop himself, but he couldn't. Nagisa hit the floor. Hard. There was a sickeningly loud crack as his head collided with the ground. There was a moment of silence, Nagisa lay motionless on the floor. His mother realised she had gone too far.

"N- Nagisa?" She questioned, her anger replaced by fear. She knelled down next to his un-moving body, a streak of blood ran down his face, over his eyes. "Nagisa, honey? M-Mommy's sorry. So please get up"

He didn't move.

"Nagisa!" She screamed, hysterical tears running down his face. Slowly, Nagisa opened his eyes. But they were no longer wide and full of kindness, they were as deadly as blue flames. Something inside him had snapped.

"Get of me, you disgusting old hag." He said, his voice gruff and full of malice. Hiromei's eyes widened.

"W-What did you say to me?" She said, shocked. Nagisa just pushed her away harshly, and stood up, his eyes filled with bloodlust.

"You know, I'm getting pretty sick of you always shouting. I think it's time I shut you up for good."

"What are you saying?" His mother cried, looking up at him- But the Nagisa she knew was no longer there, the boy who stood before her was a cold-blooded killer. Nagisa's bloodlust unleashed. Nagisa grinned, and picked up a knife.

"This is for all the times you hurt me, and controlled me, and tried to make yourself feel better about your own pathetic life by living through mine." He growled, his eyes widening with madness. He picked up a knife from the counter top, it glinted menacingly. With the blood running down his head into his eye, he was the picture of insanity.

"Nagisa, stop it!"

He raised the knife.

"Nagisa! No!"

He plungd the knife into her chest.

I'm going to be late! Nagisa thought, as he run to school in a panic. He'd argued with his mother this morning (He couldn't remember exactly what happened though) and lost track of time. On top of that, he had to bandage his head after she'd pushed him too hard. He was sure that she didn't mean to hurt him, her emotions just got a little out of control sometimes.

"Running late?" Somebody said. It was his old 'friend' from second year, the fat one with the freckles, stood next to him was the tall pointy looking one with glasses.

"It must suck having to walk all the way up the mountain to school, if you snooze you'll be late. But that's what you get for being so stupid to get into E class," The glasses one said. He pushed Nagisa harshly.

Nagisa frowned. "Please just get out the way," He said, looking down at the floor. The two bullies laughed.

"And what if we don't?" The fat one sneered. "What can a pathetic loser like you do about it anyway?"

That thing inside Nagisa snapped again. He looked down, his eyes hidden by his hair. "So I'm the pathetic one?"

"W- what you tryna act tough?" The pointy one said, Nagisa grinned, then gave them both a look that sent a shiver down their spine. He took a step closer chuckling under his breath, his eyes once again held murders intent.

"You shouldn't of said that~ " he giggled. The two of them tried to run away, but Nagisa was faster. He grabbed Fatty, and slammed his head against the wall, hard enough to crack his skull. Pointy was next; Nagisa pulled a pencil out of his pocket, and slammed it through his eye-socket hard enough for it to go into his brain.

Both of them lay there, dead. the corner of Nagisa's mouth twitched up into a demonic smile. He chuckled under his breath, unable to help himself- They both just looked so funny lying there, with blood all over there faces. They were so stupid, acting tough then getting killed instantly.

Nagisa threw back his head and laughed loudly, his voice full of demonic delight. Killing them was so easy!

"Not so scary now, are you? hahahahaha!" He said, laughing at their bodies before skipping away.

"Nruhyuhyuhyu, your late, Nagisa." Koro-Sensei said, as he walked in.

"Sorry sir." Nagisa said, looking down. He had not only gotten in an argument with his mother, but those two from his old class had harassed him on his way to school and made him late. He felt really bad.

"Don't worry, Nagisa, it's only this once so I'll let you off." The teacher said, smiling. Nagisa was glad Koro-Sensei was so nice.

The rest of the day was normal- They did another experiment in science, and tried to assassinate their teacher a lot, but of course, it failed. Nagisa had the strangest feeling he was forgetting something, though.

At the end of the day, Nagisa bid farewell to his friends, and decided to go to the shop, to pick up some flowers for his mother, (Since they'd had a pretty bad argument this morning, he wanted to make up with her. He decided on blue roses, he thanked the vendor who smiled at him cheerfully.

"I'm sure they'll make any lady happy." The blond said, Nagisa smiled at him.

"Thank you very much!" The blunet grinned. He was in a better mood when he walked home, the bunch of flowers in his hand, along the way, he saw a couple sat on the bench kissing. Ah, young love! He thought fondly. Then, he realised who it was- Karma and Okuda.

A cold feeling of jealousy curled up from the pit of his stomach. No. He dropped the flowers as he walked over to them, blood-lust shining in his eyes. Karma was his.

For the third time that day, Nagisa Snapped.

R&R if you want to know if Karma and Okuda survive. This story should be re-named. Nagisa-hits-his-head-and-becomes-yandere
