Prologue: God Eater

January 8th 10.40pm

The boy was 16 years old, 168cm, around 60kg, with black spiky hair and irises. His body was very slim but toned; he didn't play sports or even go to the gym. And was wearing the school's uniform: a white button-down shirt and black pants. The spiky haired boy was also using a orange idol's shirt underneath.

He used a "DANDY'S" brand of gel, and imitated his mother's spiky hair, which she had imitated from an old magazine.

His name is Kazuo. Last name Namiari, first name Kazuo.

It was a Wednesday night, Namiari Kazuo, who was exhausted, after finishing his homework, would finally go to bed, to regain his energy. He already got into a mess earlier that night, so he was already a bit stressed.

But his cellphone ringed, it was an relaxing anime's theme song, by the way.

The call, however, was quite unpleasant. It was his boss.

"Kazu, I have a mission for you." It was the first thing the girl said, she sounded slightly tired and mildly annoyed — probably having a hard night.

And he couldn't help but to sigh in exasperation.

"Hey, I know I keep repeating this... But can't you give me something a little easier?"

"..." she remained silent, and Kazuo continued.

"Like, it's already gotten boring. I always end up involved in drug trafficking, and I end up getting shot. Well, at least you cover the hospital bill, but..." he sighed.

"Don't worry, you just need to secure one person. Simple, right?" She sounded a bit playful there, probably holding back a chuckle.

Most certainly knew how that was going to go down.

"Huh... yeeep. What could go wrong?" The boy spoke with a sarcastic tone.

"I'm counting on you." She said and hung up.

Kazuo said to himself, "Aren't you even going to say goodbye, boss?"

After a long sigh, Kazuo decides to accept the mission from the city leader and representative of the Kurokami Family, Kurokami Madoka, just 18 years old by the way, which was actually impressive to him.

Upon confirming the location of the person he was supposed to meet, who was 100 km away from his home, he decided to call a taxi to quickly reach the destination. However, the tires went flat, before even starting. Soon after, Kazuo takes his bike to avoid wasting too much time, but the brakes were malfunctioning, and he ends up crashing against the wall...

Namiari got just a few bruises, but the bike somehow was split in two upon impact.

Yes, something is visible to anyone's eyes: Kazuo is completely devoid of "luck". Getting involved in a shootout between dangerous drug dealers and the police, accidentally invading the Yakuza, and not even being able to take a taxi or ride a bicycle, to reach a destination just 100 km away.

That summed up that boy's life very well.

He then stares at his right hand in disapproval.

"Why do you do this to me? You know, after all these years, it's starting to get annoying. Is there any way to stop?"

It's nothing personal, Human.

You might be wondering, "Who is he talking to?" I answer you: in truth, all of Kazuo's misfortune has a reason, and that reason is an entity. One of the 7 Deadly Sins; Gluttony.

This gluttony fed on all of Kazuo's luck, if he bet on the lottery, he would probably lose the ticket before he even scratched it, and if he managed to win the maximum prize, he would lose it for some dumb reason.

Also, it had a pretty feminine yet mature voice.

"..."

Hmm? What is it?

"There is a way to free you, God Eater?" The boy wondered.

Bahahaha~ Of course not, idiot.

He crossed his arms, tilting his head to the side. "Maybe if we ask Kurokami-sama..."

Nah, I like it here.

"So that means you don't want to leave..."

Gluttony, or rather, God Eater went silent for a second. And Namiari became slightly worried.

Forget it, Human. Didn't you have to go find someone?

"A-ah, oh, yeah! You're right! Hmm, what time is it?"

After checking the clock on a neon sign above one of the posts, Kazuo realizes that he wasted a few minutes standing there. And then he ran off to reach a destination of 100 km, he ran for two hours and forty minutes before he got there.

A young man of just 16 years old, who at exactly 01:30 A.M eho should be in his room, sleeping... He is now being chased by 5 delinquents in their bikes, while carrying a girl who appears to be the same age as him. Running desperately, he could barely hear what those guys were saying, he was completely focused on running away.

Namiari Kazuo entered a park surrounded by a forest, lakes and some bridges; that was apparently District 21.

After a few minutes of racing, the amateur cyclists were apparently lost.

"You're amazing!" Said the girl, with an expression of admiration on her face; she was quite pretty, with blonde ponytail hair tied by a red bow.

"W-why?" Kazuo was too tired to care, though.

"Well, you managed to escape from all those people on bicycles, while running with a girl in your arms." She said with her round eyes beaming with joy.

"Uh-huh. By the way..." he was about to stop her fangirling dead in it's tracks, but...

Before Kazuo could even give any response, the delinquents from before caught up to them... the 16 year old boy, weighing 60kg, with a height of 168cm, at the peak of his physical shape was completely exhausted, his legs were shaking, and he was hyperventilating and getting dizzy, he could barely lift himself.

"Hey, brat, are you friends with that little thief?" Asked the one who seemed to be the gang's leader.

(I can't hear you, idiot... I think I'm going to faint, I didn't know that running for so long was so bad...)

In fact, there were other factors as well, but he wouldn't realize it.

"Tsk, whatever, I'll just beat the shit out of you guys, and get our money back."

That guy, who seemed to be about 2 or 3 years older than Namiari, came forward with everything and with a single punch to the already weakened Kazuo, sent him flying. He had just been thrown five meters away with just one blow... Even if he was in peak condition, he wouldn't have been able to resist it, it was impossible for a simple high school student.

As they walked up to the girl to take back the money that had been stolen from them, a thunderous sound of bones breaking echoed in the silence of the night, and as they turned in panic to see... a dragon's head.

Coming out of the 16-year-old high schooler's arm was the head of a Dragon, which was almost twice as long as Kazuo's. It roared and opened it's mouth, like a crocodile that is in the distance of the target, and with a speed that human eyes cannot follow, it snatched up the five youths, and swallowed them completely.

...

A few minutes after this incident, Kazuo wakes up and is strangely well, for someone who ran a marathon for 5 people.

"Uah! What happened to my arm!?" The boy shouted, startled at the dragon's head coming out of his arm.

Hmm? That? No big deal, I just took control of it to save you. I've done this once before, but you were unconscious.

"A-Ah, I-I understand... but how do you get back to normal?"

You just need to wait a few more minutes. And by the way, as an extra service, I spit out those 5 idiots.

"Ah, thank you for that. But whatever. Where's the girl?"

She left.

"And... *You* let her?"

Why wouldn't I let her? God gave free will for this, right?

"I-I don't know if that's the case. OTHER THAN I WON'T GET PAID!! Uaaagh!... whatever! Let's go home."

Great idea! And I still need more food!

As if magic, Namiari's arm was back to normal.

"Huh? Oh! It's back to normal and it's in one piece."

He got no answer.

The bearer of the sin of gluttony scratched the back of his head.

"G'night, partner."
