Omega!Light - How do his plans change? If he had a mate?
Anon: How about light yagami as an omega? It would be interesting considering how he plans on being 'justice and creating a new world. How would he feel of having an alpha mate?
Anon: Could I request for an omega light. I feel like it would really be interesting and it would make sense with the story line a bit. Considering he wants justice and all in an alpha-dominated world. "Omega rules over the world type of stuff "
(Hmm, this was an interesting one to write! It was a bit of a deep dive into Light’s psyche~ I’m sick at the moment and not taking my classes so I’m bulk writing some older requests right now! Sorry it took me so long to get to this. Enjoy!)
Warnings: Mpreg, Discrimination, Light’s general blasé attitude towards murder.
Firstly, let’s look at the omegaverse world in Death Note (pre- Kira) and how it was for Light growing up as a male omega.
Light’s experiences with discrimination very much shaped his desire for justice. He felt like he was never given justice for the way he was treated and he was going to change that.
Omegaverse Japan was very prejudiced against omegas and Light felt these effects at a very young age.
The first time was with an elderly neighbour of his. When his mother was proudly showing off his recent perfect test scores, the neighbour dismissed them with a comment about how he shouldn’t be focusing on education but on training to be a good mate and mother, and that alphas didn’t like omegas who focused outside of the family and the household.
This was extreme, but it did reflect the biases of the older generations.
At only six, Light was crushed, even if he kept those feelings to himself. Eventually, he vowed to show everyone who thought he couldn’t do ‘alpha things’ that he could, and not only that but he was better than any alphas at those things.
Other examples of discrimination he faced are as follows:
Being told by his teacher that he should pick a new future career because “being a police officer is a demanding job. You’ll need to be at home for your future pups, Light kun!”
Alphas at his school never taking no for an answer when he rejects their advances (and the teacher ignoring this behaviour).
Gaining the attention of sleazy adult alphas starting from when he was only 14.
In public, Light tried to play both a respectful genius and good omega boy.
He would never dull his intelligence too much, but he remained soft-spoken and manipulated his way out of situations without causing a fuss. Eg. Claiming he was waiting until he finished school to court, rather than just rejecting his alphas classmates outright.
Light just found that this strategy made people leave him alone more often and therefore was his favourite.
And then he finds the Death Note.
As an omega, Kira’s actions change ever so slightly.
He is very harsh on hate crimes against omegas.
He goes so far as to seek them out, rather than mostly getting names from watching the news.
This has the unfortunate side effect of L figuring out almost immediately that Kira is an omega though. Which ultimately increases suspicion on Light.
When Light finds out that L is also an omega, he can’t decide if he feels more or less angry.
On one hand, he was imagining an arrogant asshole alpha that he would have been delighted to kill, so this is a more tolerable alternative.
On the other hand, shouldn’t L be supporting him making the world safer for omegas like them? It feels like L is betraying his kind which makes Light angrier.
In the earlier days, Kira’s focus on helping omegas and closing the discrimination gap makes him pretty popular, especially on anonymous internet forums.
Light met you at university. You were a tolerable classmate who expressed an interest in courting him.
Light, although he had no interest in you, accepted the courtship to get L off his back. L had theorised that Kira was either an unmated omega, or mated and very angry/regretful about it. Considering Kira’s age, he decided it was likely the former. For this reason, he figured being in an active courtship would throw L off.
Light picked you because you were one of the more tolerable alphas, but he found himself surprised at how much he enjoyed your company.
You actually listened to him, valued his opinions, supported his dreams. He found himself thinking that it wouldn’t be that bad to be mated to you.
He pushed those thoughts back, following the courting motions with as little emotion as possible.
But when he was in heat (a minimised one because he takes suppressants) he just really wanted you there with him. He was so confused and angry that he was feeling this way, but he caved in and called you over to spend time with him.
As he laid in your embrace, he started trying to justify what he was doing.
He liked to think he was a god, but ultimately he had the lifespan of a human. Who better to continue his legacy than his own child? For a child, he would need a mate. And you were the most tolerable alpha he had ever met. That’s the reason he was doing this.
So, he puts out feelers to see your opinion on Kira and eventually he tells you who he is. He is gleeful when he receives your support.
From this point, he throws himself into the relationship a lot more, moving on from courting to intended mates.
He loves having someone he can be himself with. He never has to put up a mask with his alpha.
His plan is to get pregnant after he’s established the new world order, then raise his child to take over when he’s too old. He doesn’t care what their primary or secondary gender is because he plans to make sure they are raised to be a suitable leader.
Light gritted his teeth as he persevered through his university coursework. His heat was driving him mad. He skin was itchy and he couldn’t focus properly.
It would probably be better if you were here with him.
No. He gripped his pen tightly. He didn’t need anyone else, certainly not an alpha. He was fine. He just needed to lay down for a bit, then he’d feel better.
Closing his textbook, he stretched and made his way over to his bed, supressing a whine at the lack of a nest. No, he didn’t need a nest he was fine.
Okay, maybe he wasn't as fine as originally thought. It had been a few hours and he was only feeling worse. Maybe he should send you a message. Just so he could get back to work of course.
You knocked hesitantly on Light’s front door, clutching your bag tightly. Light had sent you a cryptic message and you were a little worried about him.
His mother opened the door and ushered you up to Light’s room with a smile. You thanked her politely before walking quickly to Light’s bedroom. You knocked twice before tentatively swinging open the door. You saw Light sitting up in bed, looking a little ruffled, like he’d been asleep. You took a deep breath. He was in heat... The omega you were courting had just invited you into his room while he was in heat! Your alpha puffed up in pride.
But... where was his nest?
“Hey Light.” You spoke quietly. “How are you feeling?” You moved to sit on the edge of his bed, watching carefully for any signs of rejection.
“Like crap.” He let out a strained laugh. “I need to get my work done, but I can’t do anything like this.”
You hesitated. “Where is your nest? You’d probably feel a lot better in there.”
“I don’t have one.” Light said shortly.
“Oh!” You said, flustered. “That’s fine. I just thought- but that was rude, I’m sorry.”
Light rolled his eyes. “It’s fine, just drop it.”
You let out a sigh of relief, scooting closer to him and wrapping an arm around his waist. Light automatically leaned onto your shoulder before realising what he was doing and starting to pull away. Before he could, you tightened your grip, releasing a calming scent as you enjoyed the physical affection. Light hesitated, but the feeling of burning itchiness was finally starting to subside and he couldn’t help but lean into the person providing the soothing sensation.
He was only doing this so he would be feeling well enough this evening to write in the Death Note. That’s it. Nothing else.
