Lets have some fun:

Death of their hearts

01; Welcome to the good life

As Riku stepped outside his front porch he gazed into the grey sky that was pouring water. "Why does it always have to be raining...WHEN I'M TRING TO GO TO THE F**king STORE!" he bellowed angrily. He sighed in disappointment. Down the street a man was running, a hood over his head and he held something tightly against his chest. "Here!" he yelled handing Riku a black book. "Who the hell are you?" Riku asked as he lifted his right eyebrow. "Just keep it! Do whatever you want with it! Good bye!" he ran off dropping the black book onto the wet pavement. "Just what I need. Some weirdo handing me things..." he sighed once again leaning down to pick the black book up. On the cover of the book it spelled out in script writing; DEATH NOTE. "What the hell is this?" he questioned as he opened it, "There's also a how to use manual?" He suddenly thought, 'hey what the hell? Maybe I should throw it away or...be amused at this damn thing until the rain stops."
He opened the door to his apartment complex and traveled to his small apartment. "Number one-" he began to read as he sat underneath his kotatsu table," The human whose name is written in the note shall die. That's some pretty heavy stuff, but not impressed. Is this a chain letter?" He scanned through the rules until he found, "3. If the cause of death is written within 40 seconds of writing the person's name, it will happen. 4. If the cause of death is not specified the person will simply die of a heart attack..." The smell of the heavy, winter rain got to Riku and he fell sound asleep under the kotatsu.

"Wake up...or else I'll KILL YOU AWAKE!" a harsh voice screamed. Riku suddenly jumped from underneath the kotatsu and stared at the demon looking boy. "Oh finally. So this is what the new DN owner looks like." he spoke. "Huh? What...the hell are you doing in my home?" Riku muttered as he crawled back underneath the kotatsu. "Make me cookies...Kia-" The boy grabbed the table and lifted it up.
"Brr..." Riku shivered. I'm talking!" the boy bellowed into Riku's ear. "ACK! And here I thought this was a dream!" Riku said placing his hands over his ears, "Who..." he looked at the boy with black spike hair, yellow eyes like a cat and large black wings. "Shinigami Vanitas." he introduced himself. "And the owner of THAT Death Note." Riku looked over on the table and gazed at the book. "I'm in dream land." he smacked himself on the face, "Ow!"
"Idiot! BAKA! BAKA! You want me to sing Stupid MF (Stupid MF by MSI) for you?"
"No thank you. I think I'm alright." "Well Riku, you have the power to kill. What are you waiting for? KILL!" Vanitas demanded. "I don't believe you." Riku admitted. Vanitas floated to the TV and turned it on.
"Where's the damn news when you need it." he said clicking the remote until he found channel 110 news, "Kill him! Satio, hmm can't pronounce his first name." "How?" "GRR! Didn't you read the F**king HOW TO USE? You write it! WRITE IT WITH A PEN!" Riku got up and walked over to his cabinet and searched for a pen.

"I know I'm having the WORSEST nightmare ever! A tempered God of Death! A book that kills! The only thing real is me, having to work at a JOB, Just Over Broke company that lets me create kid characters that come to life and I'm a 23 year old man!" he thought as he found a pen and sat at the table. He grabbed the book and opened it.
"Yes..." Vanitas hissed under his breath. "This is stupid..." Riku muttered as he wrote down the name of the news person. "How do I want him to die?" Riku asked as he placed the pin in his mouth.
"THERE!" Vanitas bellowed as he pointed to the screen. Saito grabbed his chest and killed over.

"OH MY GOD!" a woman shreiked in the background.
"TURN IT OFF! TURN THE F**KING CAMERAS OFF!" a man bellowed as he jumped in front of the TV. "Beeeeeeeppppp" the TV chimed as a picture of a usagi (Rabbit) appeared. Riku's mouth slowly opened in awe.
"I actually killed someone...and he was my favorite cast of News 110 too!" he yelled as he jumped to his feet.
"What's this feeling?" he thought as he looked at his hands, "This feeling of intentions murder."
"Even if I can kill people with a book Vanitas, who the hell do I kill? Does it look like I have some revenge on people except the sky which keeps crying!" "You can rid the world of evil." Vanitas suggested.
"Oh please! You can't rid the world of evil! And I'm not that kind of selfish person. I work, and-"
"AND you have forgotten your past right?" Vanitas smirked.

Riku twitched when he knew Vanitas saw right through him. "I know all about you. You woke up in the cold streets right here in this town with only the name Riku in your pockets. How bout we kill the people who know about you and made your past life miserable?"

Ending!
