3rd person POV:

Ryga Academy, infamous for being one of the hardest schools to get into, a place where only the elite geniuses are allowed to learn in.

But that is all a cover. In reality, this is a school for young killers from Assassin clans, hidden from society.

Inside the principal office, sat the man who created the school.

A black-haired man wearing a nice expensive suit with an eye patch.

(Akuma Oni)

As he sat patiently a woman entered his office bringing a smile to Akuma's face.

Akuma:(smiles) Ran-chan~

The woman had brown hair and eyes. She wore black clothing and held a katana to her side. Between her pale skin and dark clothing, the only colorful thing about her was her red lips.

(Ran Gina)

Ran:...(sigh) Ugh... Hello, Akuma.

Akuma: So how did it go?

Ran: Are you sure he's Kira? You know... The infamous killing prodigy?

Akuma: I'm quite sure.

Ran:... Him? Like, seriously?

Akuma: Why don't you explain how his test went.

Ran: Alright.

(Several hours ago)

Ran: We're here.

She exits her car and proceeds to lean against it as a young male comes out of the passenger seat of the vehicle.

The young man had messy hair, tired eyes, and wore a white hoody with shorts.

(Yn Zeiro)

Yn: This...looks like a karate dojo.

Ran: It is.

Yn: Ah... I'm still confused.

Ran: The dojo is just a cover for clan kids to spend their summer camp in the cities.

Yn followed Ran into the building where they saw a group of 10-year-olds practicing.

The sensei of the dojo, a mid-forties woman, then approached the two.

Woman: How can we help you?

Ran: We're here for the Ryga initiation.

Woman: I see. Students! Line up, and prepare to battle!

Yn:?

Ran: The principal thanks you for giving him this trial.

Woman: It's nothing. One less favor I someone the better.

Yn: Hold on, who am I supposed to fight against here?

Ran: The kids.

Yn: Are you serious?

He walks up to the group of kids ready to fight.

Yn: This doesn't seem fair. They're not even half my size.

Ran: Just do it.

Yn: But they're just kids.

Woman: Begin.

The children take up a fighting stance.

Yn:(chuckles) Kids, I'm more than twice your size, so why don't we-

One of the kids jumped up and dropped kicked Yn into a shelf. Slumping to the floor, all the objects on the shelf fell on top of Yn's head.

Yn: GHA!

Girl: No mercy!

Kids: YEAH!

All the kids began rushing up to Yn to attack him.

Kids: HYAAAA!

Yn: AAAAAAAAAHHHHHH!!

(Present day)

Ran: To sum it up, he got his ass kicked by a bunch of 10-year-olds.

Akuma: Hmmm... His amnesia is worse than I thought.

Akuma: Oh well~

Akuma: Looks like he's going to need some training from a certified master.

Ran: Oh no, you're not dumping him on me! I did what you asked for.

Akuma: Please Ran-chan?

Ran: No. And stop calling me that!

Akuma: Training the great Kira and helping him back to his feet is a great honor.

Ran: Or a sure-fire way to get me into a ton of trouble that I'm in no way prepared to deal with. It's a no.

Akuma: What if I... Sweeten the deal? An upgrade to what I previously promised?

Ran:...(sigh)

She takes out a cigarette. Snapping her fingers, she creates a small flame to light it.

Ran:(blows smoke)

Ran:... I want to keep the car.

Akuma: Deal. Have him ready to face the younglings in two to three weeks.

Ran:(smokes cigarette in annoyance)

(A day later)

Deep in a forest away from prying eyes, Ran leaned against a tree with a cigarette in her mouth, as the young man called Yn walked up to her while panting.

Yn:(panting) Oh man... That...that was a long hike. (gulp)

Yn: So we're... What are we doing here?

Ran: I've been tasked with whipping your sorry ass into some kind of shape before the end of the month.

Yn: Cool. You're going to teach me how to use a sword or something?

Ran: Hahahaha! No.

Ran: Basic combat. Should be enough for you to beat those kids.

Yn: I have to fight those monsters again?

Ran: Out of all the initiations the school can give you... Well let's just say, you got lucky.

Yn: Alright. Where do we start?

Ran: That tree.

She points at a tree next to him.

Ran: Punch it.

Yn: Okay...?

Yn:(punches tree)

Yn: Ow, ow, ow, ow!

Ran: Punching hurts.

Yn: I didn't think it would hurt that much!

Ran:(mind)... I should have studied drunken martial arts.

(Two days in training)

Yn was doing pull-ups on a tree branch until it broke and he fell to the ground.

For an assassin like Ran who had been thought how to land, she simply cringed at seeing him.

(Five days in training)

Ran came back to the training spot after restocking on cigarettes to find Yn working out to music coming from a boom box.

Yn:(humming) You're the best, around♪... Nothing going to ever keep you down♪...

Ran: Ugh...

(Smash)

Taking her sheathed sword, Ran smashes the boom box like watermelon.

Yn: My toons!

Ran: This training is secret. We don't need music to attract unwanted attention.

Yn: You could have just turned it off. Man... There goes five thousand yen.

Ran: Wait, where did you get the money?

Yn:.... I'll pay you back, I swear.

Ran:(glares)

Ran: Today, you'll learn two things. To dodge, and not to take money from me.

Yn: I'm sure that's-

Swinging her sheathed katana at Yn, the young man immediately ducks the first blow and starts running as Ran chases him.

(2 weeks in training)

Yn: When am I going to learn some cool ninja skills?

Ran: That stuff takes years to learn how to use correctly. Since your opponents are children, how to punch and kick should do.

Yn: Ugh, fine.

Ran: Don't give me that! (mumbles) You should already know how to fight.

He continues to train as Ran thought him. After a while, Ran asks him a question.

Ran: Why are you doing this?

Yn: Because you're making me!

Ran: If you don't like it, leave. Not my problem if you don't do it.

Yn: Yeah, but then I won't get into the school.

Ran: So? Why do you want to go to a school for killers?

Yn: With no money, no family, or place to stay, going somewhere else isn't really an option.

Yn: I need some kind of education if I'm going to live, right?

Ran: Ryga is known for being the best of the best to the public...

Yn: Besides, I owe Akuma for nursing me back to health. If I finish school I can at least some kind of job to pay him and you back.

Ran: Pay me back?

Yn: For training me... And the boom box...

Ran:...

(Last day of training)

Ran sparred with Yn who showed her all he learned.

She was not impressed. At best...whelmed.

Ran: Eh... Should be enough to beat up those kids and pass.

Yn: Alright!

Ran: Let's go.

(Day of the rematch)

Staring at the dojo were not only his initiation will be taking place, but also where he would have his rematch with a bunch of children.

Yn: Hm. Let's do this.

After tying his loose hair up he grabs his bag and saunters towards the dojo.

Ran: Stop acting cool, you moron.

Slamming the dojo doors open, Yn gains everyone's attention.

Girl: Well if it isn't the big fat loser himself. Come back for more!?

Yn: Listen here you little shits! It's time to get your asses kicked so I can get my honor back!

Girl: Bring it on you poopy head!

Boy: You tell him!

Girl 2: Ugh, stop being such a simp, Josh.

Yn: Get ready to taste sweet blood you little preteen poopy monsters!

Tossing his bag to the side he rushes towards his enemies.

Yn: HYAAAAA!

Ran:(facepalms)

Kids:(take up fighting stances) HYA!

Getting close, Yn kicks the leader of the group like a soccer ball, across the room.

A few of the kids jump up to try and grab him, but Yn just punches the kids away.

Grabbing one by the collar of their clothes, he tosses them into the child's friends.

Few of the kids got lucky and managed to get some good hits in, until he knocked them away.

Continuing his beat down, he kicked and punched until it was done.

Yn:(panting)

Looking around him, he was surrounded by children bruised and beaten on the ground. He was victorious.

Yn: YEEEEEEESSSSS!!!

Ran:(mind) Greatest Assassin who's ever lived...how the mighty have fallen.

(An hour later)

Since they couldn't before, Yn and the group of kids bowed to each other in respect after their hour-long recovery break.

Woman: Well that was something.

Ran: I need a drink...from several bottles...Yn! Let's go!

Yn: Give me a minute!

Ran:?

Grabbing his bag, Yn hands it to the kids.

Kids:?

Yn: Thanks for the fight. Sorry that I had to hurt you all.

They open the bag to find a bunch of candy.

Kids:!?

Yn:(smiles) Enjoy!

He leaves with Ran following from behind. They walk to the car and prepare to leave.

Yn: Sorry, you can put the candy on the stuff I owe you for. It's the last time I'll take something from you.

Ran:... I'll let it slide.

She takes Yn to the little apartment Akuma set up for him.

(Later that day)

Ran entered Akume's office to find him sitting in his chair.

Akuma: So how did it go?

Ran: He beat the shit out of those kids. Happy?

Akuma: I probably shouldn't be, but yes.

Akuma: So tell me. What do you think of Yn?

Ran: Caught him glancing at my breasts, ass, and katana a few times. Amongst other things he just seems like a below-average teen.

Akuma: Now tell me Ran-chan, how did his training go?

Ran: Nothing special there either, he got it done.

Akuma: But did you notice anything?

Ran:...Yes.

Ran: When I attacked him with slight seriousness, he dodged instinctively.

Ran: I think he has his skills in muscle memory just his instincts uses them on actual threats.

Ran: However, that's just a theory. I'm no expert on these kinds of things.

Ran: Anyway, he ain't my problem anymore. Now give me what I'm owed.

Ran: New identity, and the car.

Akuma: Before I do... I'd like to make you a new better offer.

Ran: Not interested.

Akuma: Just here me out, Ran-chan.

Ran:(glares) That wasn't the deal.

Akuma: You think your part is worth that deal?

Ran:...

Akuma: I'll give you your new life, and even the car. All I ask is that you stay in the city with Yn, as his legal guardian.

Ran: Do I look like a daycare?

Akuma: You look old enough to be his mother.

Ran: Fuck you.

Akuma:(chuckles)

Akuma: I need someone to look over him.

Ran: Why?

Akuma: He's quite literally, the most dangerous man alive. I understand that he doesn't seem that way, but he is.

Akuma: In the wrong hands, he could be a danger to others. You know exactly the type of people who would want Kira himself in their group.

Akuma: But if there was someone to train him, to help him remember his skills. Yn could be a great help against those same foes who wish to use him.

Ran: Help remember his skills?

Akuma: Surely you haven't been living under a rock. You've heard what kind of person Kira is.

Ran: Cold-blooded...merciless...

Akuma: Raised from birth to be the ultimate weapon.

Akuma: Now that's no life. But if he remembered his skills he could actually try living a good normal life...... And survive.

Akuma: Like you.

Ran:... Yeah, I'm not buying it. You want something from him.

Akuma: Hmm... Yeah, I kinda do. Won't deny it. But it's just one job really. Something he could handle.

Ran: Why me?

Akuma: So many reasons. Not only can I trust you, but with what you want, it's a win-win.

Akuma: So what do you say, Ran-chan?

Ran:... How long do I have to do this?

Akuma: Until he can protect himself, you are to live with or next door to him. Then you're free to go wherever your heart desires.

Ran: Fine, I'll take the job. But you better pay me like it's a job.

Akuma: Money is not a problem.

Ran: I'll see you around then.

Akuma: Oh, and Ran-chan?

Ran: What now?

Akuma: There is also the possibility that he's simply pretending. If that's the case, then tell me if you expect that he is doing so.

Ran: Understood.

She leaves.

(Unknown time and location)

On top of a hill, a teen girl sat on her knees with tears rapidly falling down her cheeks. Her clothes were dirty and torn in some places, seemingly from getting caught on some things.

A boy, much younger than the girl stood directly behind her, with one of his arms around her shoulders and one on her head.

The boy's father stood near and watched.

"P-p-please..." The girl begged as she sobbed.

"I apologize, but this is necessary." The man said.

"You are an important step the boy must take for him to become something great." He explained.

"But unlike the rest that will follow after you. You alone shall be remembered." He told the girl, to comfort her.

The girl continued to sob. Begging them to stop whatever they were going to do with no result.

"Do it." Was all he said.

The girl began wildly sobbing and struggling, however, she had no strength to move her limbs. The boy behind her then directed her head towards the full moon.

Sobbing continued to echo through the air until it was stopped by a sudden bone-crunching sound.

When the boy related the girl, her lifeless body fell to the ground.

After steading his breathing, the boy turned to his father.

....

....

....

"Very good..." He told his son.
