"Mom?!" Ryuki whisperd to himself in shock as he saw his mom being devoured by the monster from his hiding place.

The monster noisely ate the prey that it had just killed. It looked around periodically, watching for any others that would try to steal it's meal.

"No way...This can't be happening!" He screamed as he held his head with both his hands. The monster could hear the small boy.

It walked over and peeked around the corner and saw the little human, cowering in fear. It licked it's lips with it's tounge as it slowly walked towards Ryuki. Ryuki heard a loud growl to left of him.

"No! Is this where I die too?! Somebody, help me! Please!" He yelled as more tears started to fill his eyes.

Something pounced on top of the monster. Ryuki opened his eyes. What he saw before him, was some sort of red lion, that had a black mane. It's tail was spear-like and had blood on the tip where it stabbed the monster. It rummaged through the dead monster, eating parts of it, until it got to a yellow shining orb. It pulled the orb out with it's paw and nudged it over to Ryuki. Ryuki, who was extremely afraid, stared at the orb and picked it up. He heard a voice in his head.

"Aragami. Beings...mass...destruction..." It rang over and over again, as if it wanted Ryuki to remember.

"Ara...gami?" He said as he looked at the lion that saved him. It was also an Aragami.

"Is that what you are, and that other thing?" he asked, hoping for an anwser. The lion nodded as put it's head down infront of Ryuki. Ryuki put his hand on it's head and petted it like it was a cat. Ryuki smiled as he could feel the kindness raidiating from it's heart.

"Not all Aragami are mean, I guess," He thought to himself as he heard a helicopter. Ryuki stood up and motioned the lion to run away.

The lion pawed the orb back infront of Ryuki as he picked it up again. A bright light shined and Ryuki couldn't see a thing. After it died down., he looked around.

"D-Didit run away?" Ryuki whispered to himself as he noticed something around his neck. It was necklace that was wrapped around his neck with a black material. At the end, there was a lion head emblem that had red eyes. He felt something coming from the necklace. It was the Aragami.

"Is this supposed to happen?" He asked the necklace as he closed his eyes. He visualized the lion as it nodded.

"Awahh!" Ryuki yelled as he fell backwards, startled. Someone walked around the corner. It was a man in a white trenchcoat that had a black trim. He had blonde hair and he looked to be in about his 40s or 50s. He held his hand out and helped Ryuki up.

The man didn't say a word as he led Ryuki over to the helicopter. Ryuki looked back at what used to be his peaceful house that was now ravaged. He stepped up onto the helicopter as it took off and ascended into the sky. Ryuki looked around and was astonished that there seemed to be a giant building near where he lived that he never noticed. The man in the white trenchcoat started to speak,

"That is Fenrir. Those monsters you saw, the aragami, we kill them," He said as the doors on the side of the helicopter finished closing.

"Aragami..." Ryuki whispered to himself as he looked at his necklace. Was he protecting this Aragami like this? Ryuki looked out the window as the helicopter landed on the helipad that was resting on top of the building. Was this where he would find his dad?

{...6 years later...}

Ryuki slid out of the way of the lightning blast. He slashed at the leg of the Aragami. It made contact. It howled in pain as it leaped over Ryuki.

"Don't let it get away!" Someone yelled as they threw a stun grenade at the Aragami. It was the 2nd Unit Leader, Sei Mikazo.

"Right!" Ryuki yelled as pushed part of God Arc up, switching it to it's Gun-Form. He aimed. Fire.

Ryuki shot Oracle Bullets out of his gun at an god-like speed. His gun was a custom, Generation 9 assault rifle. He had a custom Generation 9 God Arc. The bullets blasted the Aragami, one-by-one they hit the target, causing it to fall over. He pulled another part of the Arc down as it changed into blade-form.

"Ahhhhh!" Ryuki yelled as he jumped high into the sky. He plunged down into the Aragami in downwards drill like motion. Ryuki jumped off the Aragami, and devoured the core of the Aragami, killing it.

Ryuki kneeled on the ground, as he thought. He looked at the now empty vessel that lied on the ground infront of him. He couldn't help but think about his mother's death. Ryuki stood up. He looked over at Sei. She had an astonished look on her face.

"I guess were done here," Ryuki said as he walked over to Sei.

"Lets go, Leader," he said with a faint smile as he patted her shoulder and then started to walk back to base.

Sei looked at Ryuki as he walked away.

"He is very powerful, but he just joined the Gods Eaters. What are you hiding, Ryuki?" She thought as she started to follow him.

Sei was the 2nd Unit Leader. She had long brown hair along with light hazel colored eyes. She had been fighting the Aragami. Sei was the same age as Ryuki. She had a Custom Generation 7 God Arc that had the power of a Generation 8, however, Ryuki did not know anything about it besides it was a light weight blade that was shaped like a wing. Her shield was shaped like an eagle's head. She was an Old-Type, but a very powerful one. Even though Ryuki was a new Gods Eater, he had power and skill that surpassed even her's.

Ryuki was sitting in his room. He untied the knot in his necklace and put it on his desk. The ruby eyes gleamed as a creature started to form. The red lion appeared next to Ryuki, but was disguized as cat that had a orange-redish fur. It nuzzeled against his arm. Ryuki couldn't help but smile at the little cat, thinking about it's combat form.

"Alright Arzo, I'll pet you," He chuckled as he lifted his hand and rubbed the cat's head as it purred.

Later, Arzo fell asleep as Ryuki looked at the information about his custom God Arc. From what he knew, it was the only Generation 9 God Arc for a New-Type. He was the only one able to manipulate it's inense power, and because of this, Generation 9 Arc production was halted. His blade, Skylight Crescent, was incredibly strong along with his gun Moonlight Havoc and his shield Sunlight Protector.
He heard a knock on his door.

"Hold on!" Ryuki yelled as he picked up the necklace as he saw Arzo looking at the door.

"You got to hide, if they find out you an Aragami, you'll be killed," Ryuki explained as he held the necklace and Arzo disappeared into the it.

"Come in," He said as he tied the necklace around his necklace. The door slid open and Sei walked in.

"Hi Sei," Ryuki said as he lied down on his bed.

"What are you doing?" She said with an irratated tone.

"Relaxing, what does it look like?" Emiru joked.

"Fine, but there is something I wanted to ask you," She said as she walked in and sat on the end of the bed.

"Ask away," Ryuki replied.

"Where did you get your skills?" Sei asked as she looked at Ryuki's face.

This question made Ryuki tense up. If he told her that he trained with an Aragami, he'd be as good as dead.

"Isn't it considered rude to ask where we got our skills? But if you want to know, I took kendo as a kid," He said as he looked away from her.

"Alright," Sei replied as she stood up and kneeled down in front of his face.

"Also, I have a message from the Director," She said in a quiet voice.

"And that is?" Ryuki said as he opened one of his eyes.

"The Far East Branch is partenering up people for missions," She said with slight happy face.

"What?" Ryuki replied as he sat up quickly.

"Yep, I don't know who either of us are being partnered up with, but the Director is going to be calling me to his office in a few days to tell me. So he will probably do the same for you," She said as she got up and sat next to him.

"Just what I need, another problem to deal with," Ryuki joked as he dropped his head down.

"Well I'll be leaveing now, see ya later," Sei said with a smile as she left.

"What was that all about? She seemed to be in a happy mood. Does she already know who she's partnered up with?" Ryuki thaught as he took off his jacket.
