Prologue/Chapter 0: How it all starts...

(Shinigami World)

We find ourselves in an odd world that looked like a barren wasteland, except for the odd figures that covered the land.

One of those figures looked like a mix of a zombie and a fallen angel with blue spiky hair, gray-blue skin, yellow and red eyes, black lips that were in a frown with razor sharp teeth, black angel like wings on his back, and wore a black gothic bodysuit.

He was Ryuk, a shinigami that lived in the land of the Shinigami King, which was right now in a war with the greek god of death, Hades, and his army of grim reapers for the control of the death notes, which allowed the shinigami to kill a person, regardless of being a human, devil, fallen angel, or even an angel, by writing their names on the death note after a period of 40 seconds.

Yet they were some exceptions to this power, which were that the death note couldn't kill someone stronger than the shinigami, like a god like entity, a dragon, or even the four Maous themselves, or those that could also relate to death like another shinigami or a death entity from another religion, with the sole exception of the shinigami king, who could kill most of the mentioned but decided not to so that peace and balance could be achieved...that and he was lazy,

But Hades wouldn't care and thus, wanting to have more power than he already had, made a portion of his grim reapers and demons invade the shinigamis.

The Shinigami King told his remaining shinigami to hide their death notes, or destroy them in the worst of cases, so that Hades couldn't get their power.

Some did either of them as told, while Ryuk himself decided something a bit more...interesting...

He had sent it to the human world.

The reason for that was that he thought that Hades wouldn't even bother to look there...and because some human might find it and make things more interesting for him.

We find ourselves with Ryuk himself as he dodged another shinigami's scythe.

Now we find ourselves with Ryuk himself as he dodged another grim reaper's scythe.

"Where is your death note, shinigami?" Asked the grim reaper after him, who actually was a cute girl with long braided purple hair, golden sleepy eyes and pale skin wearing a white skull mask with a white cloak with black interior and a purple school swimsuit underneath and some black and gold armor on her arms and legs.

"Not with me, Grim reaper." Replied Ryuk with a grin.

"Then I'll force you...to tell me where...is it!" She said in a tired note from not only having fought some shinigamis before without rest, but of her many wounds.

She continued to try and slice him up with him easily dodging her strikes.

'This is gonna take a while...' Ryuk thought.

(Human World)

We now find ourselves focused on a male human boy walking to school.

He looked to be around 16 with short spiked brown hair, brown eyes, regular skin, and wore a school uniform consisting of a black jacket, red t-shirt underneath, black pants and white and brown sneakers.

He was Issei Hyoudou, a 2nd year student at the prestigious Kuoh Academy, which until a year ago was merely an all female school before becoming co-ed, and thus there was a 5-1 ratio of female to male.

But unfortunately because of some events caused by his two middle school friends, he was known as part of the perverted trio and was considered scum by women all around. And while he certainly was perverted, he didn't showed it out loud or screamed it in public like the other two.

"I swear, if a woman slaps me because of those two, I'm slapping them upside the head." He let out as he kept walking.

Unlike what everyone thought, Issei was in fact quite smart, enough to either draw or even win a chess game against Souna Shitori herself, but kept that intelligence hidden because he felt something...fishy about the student council and even the occult research club. Not something evil...but merely strange.

And thus he had to fake being a no good, average pervert (the pervert part thanks to those two) or show his intelligence and earning the interest of the student council, from which he knows next to nothing about...

As he was walking, he noticed something hidden in the bushes near the school.

'What is that?' He thought as he made sure no one was looking around before going to the bushes and picking up the object, which was revealed to be a mysterious black notebook with an odd title on top. 'Death...note...?'

"That's a weird title..." Issei muttered before opening it to the first page.

Issei's eyes widened the more he kept reading the contents of the first page until he felt something on his left arm and dropped the book with a gasp.

He looked down and was stunned to see some weird gauntlet on his arm.

"WHAT THE HECK?!" He gasped before he heard a dark voice from his arm:

[Hmm...so loud...] Complained the voice in a annoyed tone.

"WHO'S THERE?!" Exclaimed Issei looking all around him.

[Look at your arm, Aibou (Partner)...] Said the voice in a sleepy tone as Issei looked at his right arm, [...Your other arm...]

Issei did as told.

"S-So...who are you?" He asked, surprised but then again, who could blame him?

[You may call me Draigg, young one.] Spoke the voice.

"I-I see..." Issei said before realizing where he was and thus he quickly took the notebook and headed home while making sure that nobody saw his arm, but luckily for him his parents were out in town for an adult party.

He made sure to lock the door to his room as he stared at the notebook in his hand.

"Death Note...what is this?" Issei asked himself.

[The Death Note is a special notebook that allows you to end someone's life just from writing down their names. Put their names down while imaging their faces, and they die in 40 seconds due to a heart attack.] Draigg explained as he recognized the note. [But people can die other ways as long as you write down how they die...]

"Really?" Asked Issei who was both stunned, yet fearful of what that could mean.

[Indeed, but I'm surprised that you actually found one...] Answered the red dragon, [Because after all it's usually a shinigami that hangs on them...]

"He's talking about me." Came another voice directly behind Issei.

Issei froze up and slowly turned around to see...Ryuk, who was carrying a knocked out female grim reaper that was bound in chains.

"AH!" screamed Issei jumping back and crawling backwards on the floor. "WHO ARE YOU!?"

The shinigami chuckled as he dropped the female grim reaper on the bed before he answered, "You may call me Ryuk, a shinigami that's the owner of the death note you're holding right now."

"Wait, this yours?" Issei questioned nervously.

"E-Yup." He answered before he noticed the gauntlet on Issei's arm. "Oho, what's this? Is that the legendary Boosted Gear? Then that would make you the Sekiryuutei (Red Dragon Emperor) of this generation!"

"The what?!" asked Issei.

[I can help explain that...] Draigg told him seriously as Ryuk grinned, all unaware that the grim reaper was awake and listening in with curiosity.

And thus Issei learned about the supernatural world, and how thousands of years ago, there were the Three Factions. Unlike other supernatural groups (Norse Gods, Hindu Gods, Greco-Roman Gods, Death Gods, Shinto Gods, etc.) which were apparently more or less independent of each other, these three were all interconnected. Together, the Three Factions spawned the Judeo-Christian religion, and became part of the Bible.

The Three Factions of Angels, Devils, and Fallen Angels warred against one another under the leaderships of the Biblical God, the Four Great Satans, and the Fallen Angel organization, Grigori, led by Azazel, in a conflict which came to be known as the Great War. After the deaths of the Biblical God and the Four Great Satans, the Great War finally ended, but it left the Three Factions in a state of conflict. However, due to a state of extreme exhaustion after the Great War and with all three factions losing their main forces, neither of the three sides wanted to continue battling. So while there was no peace between the factions, outright battles did not occur either.

The Factions continued in this state with occasional conflicts between members who crossed paths for countless millennia until even now.

Not only that, but Issei learned from Ryuk how the Shinigami world was invaded by the army of Grim Reapers under the control of Hades, the Greco-Roman God of Death, so that the greedy god could get his hands upon the power of the death notes, which were either hidden or destroyed until the war was over and how Ryuk defeated the female grim reaper that was on the bed, but spared her for possible information on Hades and went to the human world to search for his death note, which Issei held right now...

"Wow, so I was just lucky enough to find it?" Asked Issei.

"Yeah, I guess I should say thank you for holding it for me...but I already said that." Chuckled Ryuk. "Now then, can you give it to me?"

Issei thought about it, but then a thought came to his mind...

'What if he kills me after I gave him the death note?!' He thought darkly as Draigg merely watched the events inside the sacred gear with interest.

"No offence Ryuk...but how would I know that you wouldn't kill me once I gave you the death note back?" Issei asked seriously as Ryu chuckled.

"Why would I bother taking your life? I don't exactly take souls to Heaven or Hell with me."

[But even so the shinigamis can win the remaining years of those that they have killed, regardless of whether human, devil, fallen, or even angel...] Said Draigg, not wanting to lose his recent partner until he fought the white one again.

"So can I have it back?" Asked Ryuk as he extended his arm.

Issei sighed as he made his decision. "Of course you can have it...but not yet."

Ryuk cocked his head in confusion.

"How so?" He asked curious.

"Simply, I'll keep a hold of the death note until I'm 100% sure that I can trust you to NOT kill me. After that I'll give it to you..." Issei said as he sat on his bed, next to the now awake and curious grim reaper. "No offence, but I rather be safe than sorry..."

"Touche." replied Ryuk.

[Good choice, Aibou...] Draigg approved before he said, [Now what do we do with the awake Grim Reaper?]

That made both Issei and Ryuk turn to see the mentioned reaper, who surprisingly blushed in embarrassment before she answered a low "Hi?"

Issei jumped back with his body in a fighting stance.

"W-who are you?!" Issei demanded with some fear as Ryuk chuckle.

"That there is a grim reaper." Said Ryuk while pointing at the mentioned being.

"I meant her name!" Deadpanned the Sekiryuutei.

"My name..." Said the grim reaper, catching them off guard. "...my name is Bennia...Sekiryuutei-sama..."

"Actually, you can just call me Issei."

"As you wish, Issei-sama!" She answered as he sighed and Ryuk laughed.

"So you're Orgon's daughter, eh? Quite the catch I got then, hue hue hue..." Chuckled the shinigami, making Bennia glare at him before huffing.

"Well, might as well test this." Mumbled Issei grabbing a pen.

[Are you sure, Aibou? Because once you do this, there will be not coming back...] Warned Draigg seriously.

"Not only that Issei-sama, but on whom are you even going to use the note?" Bennia asked curiously as Issei sighed.

"...Fair enough..." Issei said as he went to watch the TV in his room with both death deities watching the news curiously. "I'll need a time to think about it..."

"Yeah, cause once you use that, you can never enter heaven or hell." Spoke Ryuk.

"Not that it would matter with what I was told today about them..." Issei said as suddenly the news showed a hostage situation on the mall! "What the-?!"

(TV: Kuoh Mall)

"We are bringing you this news coverage live as several people have been taken hostage at gunpoint." Spoke the newsman.

The camera then showed a dazed looking man with a paranoid look and a gun in his arm before showing several students of Kuoh Academy, including the members of the Kendo club and Issei' two perverted friends!

"The gunmen is one Gin Wakatoshi who had been fired off his job some hours ago due to sexual harassment towards female customers. He walked into the mall and started shooting. Currently there are no casualties, but it does look like he may start shooting at any moment until his demands of 10 Million Ryo are given to him."

(Hyoudou Residence)

"SHIT!" Issei cursed as he turned around to his "guests", "Can't you do anything?!"

"Nope." Ryuk simply answered.

"Sorry Issei-sama, but I can't do anything right now in the state I'm in..." Bennia said with a frown.

[As you can already tell, I won't be of any help.] Grunted out Draigg.

~Death Note OST: 01. Death Note~

Issei sighed as he only had one option left…

'I hope that I don't regret this...' He looked at the notebook with a grim look on his face.

Ryuk's grin widened as Bennia looked worried and Draigg just grunted some more...

He opened it and grabbed his pen and sighed before writing down, "Gin Wakatoshi" slowly on the death note until he was done and, with a sigh, went to look at the TV.

He kept an eye on the clock and watched as Gin walked over to one of the students and held the gun up to his forehead.

(TV: Kuoh Mall)

"I'm done waiting. Now one of you dies!" Roared the mad man as he pressed the barrel to a certain bladed pervert's forehead!

"WAIT! DON'T DO IT, PLEASE!" Begged the student as the man snarled. He was about to pull the trigger, but gasped and grabbed at his chest as he faltered back.

Everyone then watched in surprise, shock, disbelief, horror, and/or satisfaction as the criminal died from a heart attack!

(Hyoudou Residence)

Shock was the only thing that came to Issei's mind as he saw how Gin died 40 seconds after signing his name on the Death Note...

"W...What...?" Gasped Issei. "I-It actually worked..."

"I told you so." Grinned Ryuk as he felt another soul's remaining years enter his body.

"I hope you're aware of the decision you just made, Issei-sama..." Bennia said seriously.

[I agree with the reaper, Aibou...] Said Draigg serious as well.

"It needed to be done." Hollowly muttered Issei who was still floored that he just killed a man with his own hand.

And thus, the fate of the red dragon emperor would change into that of a new god of the world...
