Meetings and promises

He didn't know what had set him off. Maybe it was his little brother sitting at the table, still expressionless after eating his pudding. The one he had saved for later, the one with his name on it. His vision grew red, anger filling him. He gripped the nearest thing he could, the table Kasuka was sitting at.

He picked it up with ease holding it above his head, the bones in his arms cracked, but he remained standing. Shizuo froze as his brother's expressionless eyes filled with doubt and fear. His arms shook under the weight of the table and the guilt of what he was about to do. "K-Kasuka." Shizuo dropped the table, turned and ran. "Nii-san."

Shizuo would get in trouble for leaving the house on his own and in the dark. But at the moment he didn't care. What was I about to do? Tears pricked the corner of his eyes. How did I? The small boy ran through the streets, not looking or caring where he was going. If he had stayed with Kasuka he would have never met the demon.

When he finally calmed down, he didn't know where he was. There was little light, except for the street lamps. Shizuo looked around frantically, his parents were going to be furious when they found him. If they found him. Shizuo walked past an alleyway, trying to figure out where he was. He couldn't recognize anything.

The small boy froze, his blood running cold as cold laughter rang through the alleyway. He covered his ears as a high pitched scream followed. "They always scream. Heh. Humans." Shizuo couldn't move, he heard the footsteps coming out of the darkness. Red eyes glinting. Run run run. Why couldn't he move? "Oh? Hello little human." Shizuo screamed.

"Why are you screaming?" The demon tilted his head, as Shizuo gaped at him, still screaming. "Oops. I forgot." The demon closed his eyes, Shizuo watched as the long tail disappeared and horns disappeared under the demons hair. "There we go. Go home tiny human." Shizuo stopped screaming. "I'm not tiny. I'm a child." The demon blinked. "What's your name?" Not many humans stayed to talk to him.

"None of your business." He let his rage build, hoping that before wasn't a fluke. He needed it to protect himself. "You're a cheeky one." He stepped back as the demon took a step forward. Shizuo let it build, attempting to pick up the metal a-board. The demon looked surprised, before a smirk appeared on his face. Shizuo felt something crack in his arm, but he didn't care. He threw the board at the demon, who effortlessly caught it in one hand. "You're interesting." The metal groaned and creaked under the demons grip.

Shizuo turned and ran, his small legs pounding the pavement. If he was lucky he would find his way back home, but if he was running in the opposite direction it didn't matter as long as he got away from the demon behind him. Shizuo looked behind him, seeing the demon still behind him. "Damn." He crashed into someone, falling backwards before he was caught by the person he had bumped into. "That's not nice running away." Shizuo slowly looked up looking into the demons gleaming eyes. How? He was behind him. Idiot. He's a demon. "Let me go."

"You have to ask nicely." Shizuo glared at him, kicking with all his strength, when that didn't work he sank his teeth into the arm holding him. The grip loosened and he stepped back. The look in the demons eye was scary. It was happy Shizuo had bit him and tried to escape. He shivered as he ran again. "You're making this too easy." Shizuo yelped as he was lifted off the ground.

Shizuo opened his eyes, seeing how high above ground he was. A hesitant look above him and he could see the demon holding him, his wings spread out behind him. "If you tell me your name, I'll let you down." Shizuo kept his mouth closed. He didn't know why the demon wanted to know his name, but he wasn't going to give it to him. "Last chance." He still said nothing.

The demon sighed in mock irritation and dropped him. Shizuo screamed as he free fell, before the demon grabbed him again. "Shizuo." The demon smiled. "That's better. What's your last name, Shizu-chan?" Shizuo opened his mouth to tell the demon where to go. Red eyes met his and the fingers holding him loosened. "Heiwajima." The demon couldn't have looked any happier.

The demon set them down in a familiar park and Shizuo was glad, he now knew his way home. As soon as he was let go, he went to run. "Shizuo Heiwajima." Shizuo froze as the demon said his name. Why can't I move? The demon walked slowly in front of him. Shizuo looked at him wide eyed and helpless. "You're a bit young for me to play with. But I like you." The demon slid off one of his silver rings, sliding it onto Shizuo's finger. "You bit me. Fair is fair."

Shizuo watched as the demon came closer, lips connecting to his neck where the demon nipped and sucked, leaving a mark that would never fade. "There we go. You're mine now, Shizu-chan." Shizuo looked up at the demon. "I'm Izaya Orihara. Don't worry, I'll find you when you're older."The demon crouched down, so their eyes met. "But you won't remember any of this." Shizuo nodded, his eyes closing.

Shizuo woke up in his bed. Dazed he glanced around his room. How did he get home, didn't he run out and get lost? The small boy looked down, noticing the silver ring on his finger. How did that get there? He panicked, when it wouldn't come off. Shizuo used all his strength and the ring still stayed on, though he had damaged his finger in the process. Maybe water would help.

Shizuo ran into the bathroom and turned on the tap. He placed his finger underneath, again trying to get the ring off. It didn't budge. Shizuo gave up, catching his reflection in the mirror. There was something under his pajama top. He reached up, pulling the collar down. Between his neck and shoulder, there was a dark bruise. He didn't remember getting it. He didn't know why, but when he looked at it, he shuddered, ice running through his veins.

"Shizuo, Kasuka time to get up." Shizuo froze at his brother's name. He had tried to throw a table at him. He was in trouble. He quickly dressed in his uniform, before making his way down to the kitchen. "K-Kasuka. I'm sorry." His younger brother looked at him oddly. "What are you apologizing for, Nii-san?" Shizuo avoided his gaze. "Last night." Kasuka studied his brother. "What happened? You came home after school and went straight to bed."

What? "Kasuka I tried to throw a table at you." Kasuka sighed. "You were probably dreaming, Nii-san." Kasuka finished his breakfast before leaving the room. Shizuo stared blankly at the table. Kasuka didn't remember? But he did pick up the table and then he ran out of the house didn't he? Shizuo's gaze dropped to the silver ring on his finger. How was he going to explain that?

He left the house, meeting up with Shinra as they walked to school. "What's wrong Shizuo?" Shinra was good at picking up his moods. "I don't know." The other boys father was a doctor so he should know. "I've lost my memory. Last night. I tried to throw a table at Kasuka." Shinra raised an eyebrow. "Are you sure you weren't dreaming?"

Shizuo lifted his hand. "When I woke up, I had this. I can't get it off." Shinra stared at the silver ring, before wrapping his fingers around it and trying to yank it off. "That's on tight. The teacher is going to throw a fit." Shizuo sighed. "Tell me about it. How's Celty?" Shinra went into a speech of how lovely his special angel was. Shizuo tuned out his gaze falling to the ring.

It was Shinra's idea to go to the infirmary, for the time being they could use the excuse his finger was broken. Shinra was already learning how to be a doctor from his dad, so he wrapped Shizuo's finger perfectly. No one asked about the ring because they didn't see it.

"You're both late." Shinra covered his mouth while he hid behind Shizuo. They were both in the same close, Shinra sitting behind him as it had always been. "So you really don't know where it came from?" Shizuo shook his head whispering back. "Nope. I can't remember anything from last night. But it's not just the ring. I have a bruise as well." Shinra was silent.

"Heiwajima, Kishitani. Quiet in class." Shizuo put his head to the desk. "He was talking to his boyfriend." Before he could stop himself, he was standing up and glaring at his idiot classmate who had made the comment. Seconds later his desk was embedded in the wall, while he grabbed his arm in pain.

He looked down at Shinra. "Still think I was dreaming?" Shinra was looking between the wall and his friend, before shaking his head slowly. Then his face lit up excitement filling him. "Can I dissect you? Shizuo scowled picking up his chair. "Heiwajima go to the principals office." Shizuo groaned before making his way down the long hall.

"Did he have a go at you?" Shinra asked as they walked out of school. "No. He didn't believe me. He said to stop messing around with made up stories." Shinra laughed. "Maybe he should try pulling the desk from the wall." Shizuo flexed his fingers not believing he had used his strength again. "Maybe the guilt made you forget. You did try and flatten your little brother." Shizuo nodded that was probably it.

The pair of them waited for the light to change, before they started crossing the road. A woman in a bright red sweater walked past them and Shizuo shivered. Shinra looked at him one eyebrow raised. "Did she scare you?" Shizuo shook his head. "No, it was the colour she was wearing." He shook his head. since when was he scared of the colour red?
