Chapter 4

The difference between a genius and an idiot is the number of words that roll off their tongue.

I tapped my pencil lightly on the notebook in front of me.

The difference between a psycho and a genius would be...

My eyes flickered to the pink lamp at the side of my four-drawer study desk.

...The law.

I blinked again, shaking my head.

No, to be specific, it wouldn't be the law. Rather, the consequences of the law. Humans were similar to garden hoses. If one were to cover the tip of the tube, no matter how powerful the pressure of the water became, the water would not spurt out erratically.

The water being a human's desire and the stopper being the law in this case. The pressure of the water depended on the person's upbringing, in which the stronger the social pressures the person has been under, the deadlier one could become. And this is where the Death Note comes in.

The note gave power to defy the law, successfully removing the stopper bit by bit, at the end fully allowing the water to be utilized as a weapon. I grimaced, writing down strands of broken words.

First, I don't remember the exact dates of the event occurring. ALthough I was an avid watcher of the anime, after I started university, my passion almost immediately died out. Not to mention my tendency to only watch any animation once, no matter how much I loved it. I chuckled dryly, licking my lips.

Did I have a good memory? I wouldn't say no. In fact, my memory had burdened me quite heavily when doing exercise problems in any subject. I would unconsciously memorize the answers to the problems instead of actually understanding the formula of the problem.

Which resulted in my lack of observation academically. Yet...I was also gifted in hiding things psychologically.

The pick up of the Death Note occurred in Light's high school arc. In which occurred the 24 hour killing, hijacking of the bus, and L's movement in security cameras. A period after, Light meets l at To-Oh university. The cafe incident, which took place after the tennis match. Afterwards, it led to Soichiro's fake heart attack and Misa's appearance and Soichiro ramming a car into some kind of building. After that...

I paused, my pencil hesitantly lifting off the paper. Something happens and L dies. Yet I don't recall how. After L dies, his successors take over and go against LIght. People die, blah, blah, blah, and Near wins due to Light being impatient and egoistic.

I scoffed, leaning back into my chair and letting my eyelids close to search into the back of my brain.

If i had learned anything from the anime, it would be that Light's impatience killed him off in the most pathetic way. Pathetic as being humane. Humans could not become Gods if they didn't get rid of the very thing that defined them as humans.

Joy, anger, sympathy.

Emotions.

I reached out my hand towards the light bulb and clenched it into a fist.

Get rid of them. All of them.

"Sayu?" My brother's voice rang out behind my door before a couple of clear knocks.

"Come in!" I forced upon an innocent smile before raising my eyebrows at Light's appearance behind the door. Ever since that incident at the table, Light had undoubtedly become unexpectedly...nosy.

"Whassup, Light?" I swirled my chair to face him, deliberately spinning in an extra circle before stopping in front of him. Light watched me again with those quiet observant eyes, hiding them behind a facade of innocence.

"Not much, but usually you would ask me for help with your studies." Light's eyebrows quirked up questioningly as he quietly closed the door behind him, his fingers twitched as his gaze caught my eyes glancing at his hand above my door lock.

Oh yeah...I mused at his attempt to clear his throat in distraction. In the anime there were scenes of Light teaching Sayu. Yet...I doubt a university student like me would need help from a human in the early 2000s. After all, no matter how much of a genius you are Light, I was an undergraduate from the 21st century. As all academic knowledge would advance every 6 months...

Textbook knowledge in this era would have been more of a 'common sense' to me. Though...

My eyes lowered to the math exercises in his left hand.

...This era probably didn't use calculators or technology as much as the 21st century. Dammit, more memorizing to do. Next thing I'll be doing is mumbling the multiplication table as bedtime stories.

"Ah, totally forgot about that!" I physically smacked my forehead with my palm. "Doesn't school start next week though?"

"Sayu, it would still be wise to start preparing before school starts in order to get better grades." The corner of Light's lips lifted as he came closer towards my desk, lifting an eyebrow at the nonsensical chain of words I had written. My eyes searched his face for any void of emotion that came out as 'weird', but Light's mask was as hard as iron.

"What's this?" He pointed towards my note, asking permission to peer closer. I shrugged calmly, gesturing to him to 'go ahead.'

"I was calculating my future years." I simply said as he lifted his gorgeous brown eyes off the paper and pierced me with a doubtful look.

"I was calculating how many years I needed to graduate from To-Oh with a major in law."

"You're going to To-Oh?" Light's voice stilled at my bare explanation, urging for a slip up with my hidden intentions. In the first place, I had not expected Light to suddenly show up on my doorstep. It was smart of me to only scribble down the unsuspicious words from my thought process. Initially I had planned for the note to be vague in order to prevent Light ruffling through my trash bin, if there was any percentage of that. I never imagined the vagueness would be so useful in this situation.

Better to be prepared than sorry.

"Well," I stated, pressing my weight onto the back of my chair. "To-Oh's closer to us, at least compared to the famous law schools located in America. Not to mention my dear brother is aiming for To-Oh and would possibly assist me in getting into the school with his previous experiences."

I grinned cheekily as the tenseness around his eyes lifted with a hint of amusement.

"Sayu, that's not supposed to be the standard for your future education." Light's tone swayed innocently over my shoulder as he placed the sheet of paper back in its place.

"Why not, Light?" My eyes twinkled as I jabbed him in the side. "You pave the way, I'll follow you and make my life easier!"

"Since when were you so dependent on me?" His expression shuffled into a chuckle as he leaned against my desk with his arms crossed over each other. I blinked at his elegant posture, unbelieving of what grace flew off of his casual leaning.

"Well, my dear brother, it seems as if your little sister wants to stick with you forever!" I threw open my arms and hugged his waist, burying my face into his wool green shirt. It makes my plans easier, not to mention I can keep track of the events and be notified if my existence interfered with your actions.

Light's tender laugh echoed through his body as he let me cuddle him, unaware of my intentions. I lifted my head up so that his gaze locked directly with mine.

"Sayu loves you, okay Light? So that's why you'll never be alone. You won't feel alone."

Of course, that's because you're my favourite character.

I felt Light stiffen underneath me before he smoothly forced out a relaxing laugh.

"You sound as if the world would disappear." His mouth curved up ironically, staring at me with an underlying tone of playfulness.

'As if I was the only one left on earth.' He implied wordlessly. 'As if everyone else was invisible to me.'

I fell silent, searching through his eyes as if I could solve him just by staring. His own windows shimmered calculatingly as they narrowed at my lack of response, suddenly turning cold.

"Why?" He said.

I then noticed the reason why they turned cold-not because of my hesitancy to respond to him, but the fact that I could have brushed my words off as a joke but chose not to, revealing a part of my hidden intentions. I was suddenly lost by his reaction, not knowing how I should respond to the glimmering curiosity that lay in his brown eyes.

The Light I thought I knew would have started to interrogate me in fury. But then again, the Light I knew most was him after his desire for justice started spewing out. This Light in front of me was much more relaxed and warm. His gaze ravished me, rendering me breathless in contrast to his pale and emotionless face.

The eyes were the windows to the soul, huh?

Definitely true.

"What do you mean?" He asked again after seeing my silence, this time a bit more forceful.

'What are you implying?' His gaze questioned me.

Was he nervous? No.

He wasn't worried about what I knew, whether it was him being an effortless genius or a manipulating freak.

He wasn't angry on why I called him out. He wasn't grateful that I basically assured him that his secret was safe with me. He was merely inquisitive, curious on how I came to my answer.

He left me a choice and a warning. I could play it off like an innocent toddler, or, I could enlighten him with my own hypothesis, gaining no apparent confirmation from him. Even if I admitted my findings, he was able to outright deny them.

"You don't have to know." I spoke carefully, fluttering my fingers on the other side of his waist.

"All you need to know is that I am on your side." I glanced back at him, embedding genuine concern for the boy in front of me.

That is, I will assist you until you corner Near so I can kill you.

Light narrowed his eyes at my response while I literally saw the gears turning in his head. Yes, he knew that I understood his hatred for uncertainty. And by me telling him to 'fuck off, it's my busniess' in a roundabout way, it screamed code red to him. He hated blind trust especially when it came from himself. Asking him to trust me without telling him the reason irked him.

"I am your sister." I let go of his waist and leaned back into my chair. Disbelief and recognition flashed through his eyes as his expression began to settle down.

"Blood runs thicker than water." I echoed while he finally came to a conclusion, nodding stiffly as I plastered a wide grin and took out my math notebook.

"Now, where should we start?"

Author's note:

OKay, at this point I'll have to set up a time interval between publishing chapters.

It takes me around 2-3 days to finish a chapter, so I will update every 3rd day. That's around 2 chapters per week.

Just curious, but how long does it take for you guys to finish writing a chapter? And if you don't write any, then welp, how's the coronavirus going to you? I seriously miss the ice rink. Ever since I finished school I've been dying to skate, but then this catastrophe happens.

*Wails in the depths of despair.*

Ah, also if you need clarification, this is a Light x OC fanfic. And before you say, "Gasp! INcest!" In the fanfic I will tackle that question, so be sure to stay tuned!

Also, I am AWARE, that most fans of Death note love L, so this might throw you off or make you leave this fanfic, but bruh, I've seen so much L romance that I feel bad for Light. I mean, sure he turns into a psycho, but who says he can't also love like a normal human-

ok, I mean, the love between Light x OC is gonna turn into a..."you complete me" relationship, so I guess that's not quite normal.

Anyhow,

Reviews are desperately needed!
