Kira's right hand man

Chp 1

Meetings

Light's Pov

The world was boring.

It's boring and all I want is a little fun in life. As a 14 year old I should be having fun, going out, and playing games, chilling with friends.

Nope, because I'm a good little boy who studies and maintains the reputation of the cool kid that's top of the class.

I sighed as I leaning back into my chair, stretching my arms and cracking my fingers. Rolling my neck and slouching in my chair. I stared at the offending papers in front of me. It wasn't that the assignments were hard, no I could do it, I am Light yagami after all. It was the fact that it takes a lot of time and that is was boring. Nothing challenging at all.

"Light Kun! Can you come down and help me" Sachiko, my mother called.

"Coming!" I called back as I got up and left my room.

On my way I passed Sayu's door and inside I saw her watching some movie with an upcoming actor named Ryuga Hideki. I shook my head and a light smile passed my lips. 'So sayu's getting into that stage of life' I thought as I got to the kitchen.

"Oh Light kun, I'm sorry to interrupt you and your homework but can you help me set up the table, your uncle and cousin are coming to stay over for the weekend" mum states as she cooks.

"Oh yeah…How many years has it been since you've last seen him? Your brother I mean" I asked and a sad smile was placed on her lips.

"16 years, and during those years, his wife passed away suddenly" she looked sad and I nodded as I began setting up the table.

"Dad coming soon?" "I'm Home!"

I gave an airy laugh at the coincidence and turned to see Sochiro, looking tired yet brightly smiling.

"Light" "Father" we exchanged greetings.

"So, when's your relatives coming over?" he asked.

"Half an hour, so we better hurry" and with that I started setting up the table.

Half an hour later

As if on the dot the door bell rung.

Sayu went to open the door as the girl had come down from her room around 15 minutes ago.

"Hello, you must be Sayu?" a deep and velvet voice asked.

"And you must be my long lost uncle and cousin" I heard Sayu joke back. As deep laugh was given.

Footsteps were heard and in came Sayu, a tall male behind her.

He had Maroonish red hair that was combed back neatly, lightly tanned skin and dark violet eyes that were cold although his face showed a light and friendly smile. He wore a brown coloured suit and on his tie was a leaf pin. He looked professional and that he meant business instead of going to meet his sister's family.

Suddenly I noticed a small body behind his. A kid, maybe 10 or 11 years of age. He had short strawberry blonde hair and passive violet eyes. His face held no emotions as he half hid behind his father.

"Gakuho! It's been too long!" Mother cried out as she went over to greet the man. Enveloping the man in a sudden hug, he was startled yet he hugged back. The icy coldness was gone and it was replaced with warmth and love.

"I've missed you Sachiko" smiled Gakuho.

Once they were done with the hugs dad went up to the man.

"Sochiro Yagami" "Gakuho Asano" they both shook a firm handshake and once they released there was approval in Gakuho's eyes.

"You chose a good man little sister" both mum and dad went red.

"Gakuho!" Mum called in embarrassment.

"It's a good thing Sachiko, you have good taste"

Mum was still red but said nothing.

"Sayu Yagami, but you know me" Sayu grinned and Gakuho grinned back.

"Of course" Gakuho smiled back.

"Light Yagami" I stepped forward and as we shook hands Gakuho's hands were firm. We stared at each other for a moment and it felt like an hour until he let go.

"Your son will amount to greatness Sachiko, I know he will" Gakuho comments.

"That I have to agree with, Light has always been a good boy and has always been top of the class" Sachiko boasted proudly.

Gakuho chuckled. "Gakushuu has always been top of the class too, I guess its good genes"

"Oh! Poor Gakushuu, we forgot all about you" Mum went over to the small boy and gave him a hug and kiss on the forehead.

"Adorable little boy isn't he?" Smiled Mum. "He too will amount to greatness dear brother, now let's eat" Mum hassled all of us over to the table.

We all sat and began to eat. Mum and Uncle Gakuho began to chat and catch up on life with each other.

"So, I believe I've heard your name before, are you somewhat known for what you do?" Dad asked innocently enough and Gakuho gave a grin.

"Well I do run a school, that must be why" The man said.

"Oh, and what school is this dear Brother?" Mum asked.

"Kunugigaoka Junior High School" we all nearly spat out our food.

All of us stared at the man wide eyed.

"You mean that famous school for the smart?" Sayu questioned and Gakuho gave a smile and a nod.

"Well then…I always knew you'd use your unlimited knowledge for something, teaching is a good thing, running a school must be tiring" Mum states.

I felt eyes bore into me and I look up to see Gakushuu looking at me. Then I noticed it. Intelligent eyes they were, they held sadness and lust for power, a want for a challenge and they reminded me of someone, his eyes reminded me of my own.

I broke eye contact as I ate.

"Light Kun"

"Yes Mum"

"Gakushuu will be staying in your room"

"Oh"

After Dinner

I led Gakushuu to my room and the boy followed quietly. Once at my room door I opened it and let the boy in.

"You can have the bed if you want to, settle your things down and go take a shower if you need to, it's down the hall to your right" I state and the boy puts his stuff on the bed and takes out some clothes.

I settle on my desk chair and watched as the boy hurried out.

For the son of such a confident and carefree man he was very…cautious. I sighed as I took out a futon and set up my new bed for the weekend. Once done I went back to my assignment that laid on my desk.

"Might as well do it now than later" I said softly as I started it.

A few minutes might've passed until soft and small footsteps sounded. A soft plop was heard and I could feel eyes yet again burn into me. I turned around and raised an eyebrow.

The kid's hair was slightly wet and now he wore loose fitting pyjamas.

"I'll be up for a bit so if you want to stay up a bit or go to sleep I don't mind, just don't make too much noise" I state as I turned back.

Minutes passed as I worked on the assignment when a hand was on my shoulder. I looked up to see the kid hovering over me and staring at the work I had in front of me. Suddenly he did something that shocked me speechless. He scoffed.

"Please, that's what junior high school work is? That's easy, just takes a bit of time" Retorted the boy in a soft voice yet it was firm, just like his fathers.

"Uh yeah, that's why I thought I should start it now, I may be top of the class but it will still take 3 days at the very least" I state back after getting out of my shock. The boy noticed and gave an innocent smile.

"Need help?" the boy questioned and I was wary in letting an 11 year old help me with my work. Gakushuu noticed and sighed before pushing me over in my chair.

"Come on, like you I'm also top dog" I didn't budge as I stared at him. "Scoot over a big fatty, I can't help if you won't let me sit and as far as I can tell there are no other chairs" I didn't say anything.

He gave a heavy sigh and suddenly sat on my lap with a thump.

"Hey!" I called out at the sudden weight as the offending boy started picking up some papers.

"Have another pencil?" I gave him a glare before pulling out another pen.

"You know, unlike your father you're very rude, especially for a kid your age" I state and Gakushuu gave a little smile.

"You don't know my father like I do because I get it all from him" he grinned and started to write things down. "Annoying is what people like my father would describe me as, a pest, flea, know it all, brat" Gakushuu laughed yet it fell dead, his eyes were hollow of emotion.

So he was that type of kid, top of the class yet bullied because of it. We weren't the same in the slightest then. While he's picked on for his intelligence I'm honoured, loved, respected and even feared by some of the people around me.

"You know I like the annoying and brighter version of you better than this emo one" I state and the boy looks at me, almost whip lashing me. "Also, if you used your intelligence and your cards right, you wouldn't be getting teased or insulted by your classmates" I said with a raised eyebrow.

"What do you mean?" Gakuho looked clueless and it was cute and innocent.

"Well let's say in your case, you're smart and top of your school but when it comes to power and respect, people give you none because you haven't shown them why and how you should be respected. I for instance have power and respect. Why? Because I'm friendly, I'm not all academics because I show that I'm powerful and worthy in sports and fighting, I'm also pretty hot so that's a plus for the ladies" I state and Gakushuu gave a crude look of disgust.

"What!? It's true" I said and the boy nodded, thinking it over when something clicked in his mind.

"I've got a proposal for you Yagami san-" "Call me Light, we are family idiot" I state and the boy blushes.

"Uh sure, as I was saying before I was rudely interrupted" I glared "You teach me how to become this new and improved hot stuff that you talk about and I'll help you finish this boring thing you call an assignment, do we have a deal?" the boy got of my lap and held out his hand.

I stared at it and thought of any benefits for the future. How could a little cousin like him help me in any way? Then I thought of his dad, a rich and powerful man in the education and academics department. Plus, anyone related to me should not be getting picked on. I sighed through my nose and grasped the younger boy's hands.

"Fine" I state and Gakushuu looked excited at this. The kid's eyes looked devious and a Cheshire grin spreads onto his lips.

'This kid is like me' I mused.

TIME SKIP

Gakushuu was a fast learner, as his teacher in the kid's social life I taught him everything he needed to know. How to manipulate others and to get benefits off deals he makes with people. He was a natural at masks as well and by the end of the weekends Gakushuu was a pro. His first test subjects were my family, even though I was reluctant for him to use them like lab rats at first.

Although it was a success, all of them believed that Gakushuu was a cheerful and likeable kid. But of course Gakuho noticed the change in his own son.

"Raito nii, see you again soon!" I smiled at the boy, Gakushuu had taken a liking to calling me his older brother.

Gakuho came up to me and gave me one of his angelic uncle smiles. He hugged me and I was a bit surprised yet hugged back when I heard his voice.

"I know you've changed and taught him the ways to being manipulator" Gakuho's voice was deep and it had a deadly tone to it. "For that I thank you for changing my weak son into something stronger, your service is appreciated" something was put into my hand and that's when Gakuho let go of me and began walking away, a hand on his sons shoulder.

Gakushuu looked troubled at the exchanged but smiled once again after I gave a look that said 'I'm fine'

They both walked away but that's when I noticed the change in Gakushuu and that he wasn't just a kind uncle. His grip on Gakushuu was absolute and iron like. The gleam in his deep violet eyes was deadly and held something that a predator would have. It was also when I noticed the mask he had on, once he showed me bits of his personality I could finally see it. That smile was nothing kind and his calm demeanour only shadowed the ugly and evil one underneath.

"Light Kun are you alright?" Mum asked me worryingly and I looked up and smiled.

"I'm fine, absolutely fine" I smiled 'so masks and manipulation does run through my veins'. Life might get interesting with these two males.

"Don't worry Light, they'll come to visit from time to time" Father States and I nodded as I go back inside and to my room.

I looked to my hand to see a roll of money and a piece of paper. On the piece of paper was two phone numbers and two emails, one for both father and son.

"We are totally related" I chuckled as I settled the money and piece of paper next to my completed assignments.
