The Demons' Alpha

♠️ 5 ♠️

If anyone were to tell him he would eventually try finding a mate in the past, Byleth would not believe them. He would shoot it down, saying it would waste his time and no Omegas would have his interest.

Besides, the Omegas would only like him as Alpha and wanted to experience it. Not having thoughts of spending their life with him.

His ambition to stay single is crumbling right away ever since his encounter with Zeldris. And the fact he discovered they are fated pairs.

He assumed that Zeldris was taking the fated mate thing to his advantage to mate him for just being an Alpha. Byleth was glad though that his assumption, even though he mentally kicked himself for it, was far off. The Executioner genuinely likes him and wanted to have a relationship with him.

Because of this, Byleth relaxed and slowly started to open up to him overtime as the days passed. During the next week, all they did was talk among themselves to learn each other more and sometimes sparred.

It was always a draw, as the Alpha in Byleth was in pride at the fact their Omega is a skilled and strong swordsman as well. It was no surprise since he is part of the Commandments.

One thing Byleth learned was that Zeldris is highly possessive of him. It was that one day when Byleth was, as always, approached by a rather bold and flirty Omega.

She would not leave him alone and drop hints that she wanted to be fucked by him. Byleth tried his best to ignore her and shoots her down, but she was persistent.

Byleth thought he was gonna have to pull the Alpha card to scare her away. It was then Byleth had heard the most pissed off growl he has ever heard in his entire life.

For a second, he thought for sure it was an angry Beta this Omega might be mated to coming to beat his ass. Until said Omega was harshly shoved aside by Zeldris himself as he looked severely pissed. He realized it was from him, and the Demon mark had extended to his forehead like his older brother.

Byleth stared with slight wide eyes, as he watched Zeldris beating the shit out of the Omegan Succubus with fists while she tried to fight back to win Byleth but failing. There was other demon folks watching this unfold, with some Betas whistling and cheering as they enjoyed the show while the Omegas looked terrified wondering why Zeldris involved himself between the Succubus and the Pure Alpha they desired.

He wasn't gonna lie but... seeing Zeldris all worked up and beating the shit out of anyone... was kinda a turn on. Byleth blocked unholy thoughts away as his Omega wanders away from the severely beaten Succubus and dragged him out of there. The demon prince became clingy and touch starved, likely wanting to forget the 'filthy urchin' as he called her.

The other thing was him being a bit of a flirt. When he asked for cuddles, Byleth was about to pull him in for an embrace when he beat him to it. Only except he stuffed his face into his chest, and Byleth swore his face had burned red at his bold move.

Did he know he had a thing for his... chest(or titties he wanted to say to himself)? He knows they're toned but fuck they felt plushy. It got a bit heated since he absentmindedly started touching them, and his mate was leaning into the touch purring.

At least it did not escalate, but damn his Alphan side was begging him to do it. Still have his self-control he had always prided himself in.

As for meeting...

When his sister and mother met Zeldris for the first time, the first thing Sitri had done was scolding Byleth for whatever he had done to bring the demon prince in their household. Not before she gave him a slap on the back of Byleth's mint head. When he, along with Bella in his defense, told her Zeldris is his fated Omega she literally fainted on the spot out of shock.

Upon recovery, Sitri panicked and started fumbling apologies and greetings to the bemused raven-haired demon. Then later on, Jeralt somehow caught wind of this and pulled his son aside to not only congratulate him stoically but also to treat the prince well. He rather not have his son fooling around with him by making stupid choices and angering the Demon King.

But he understands.

Zeldris was taking a bit longer than usual. They always meet up in the training grounds like the first time they met truly. But Byleth was keeping himself occupied with his usual training protocol.

He went shirtless, revealing his lean yet toned upper body that left many Omegas drooling at the sight. His body is like the kind of body swordaman would own for years of combat. And the fact he is covered in a light sheen of sweat gave them unholy imagination of him doing them.

Earlier, Bella was there with him and they sparred for quite a long time. As usual, it was always either a tie or a win between him and her. At one point, she was approached by a fellow demoness who asked for her aid and so they cut their sparring session short.

The demoness in question was someone that Byleth noticed right away she's an Omega. Luckily for him, she held no interest in him, but instead gave most of her attention to his sister. Even though truthfully, Bella was hesitant to leave but Byleth reassures her that they can continue tomorrow.

If he had to be honest, that demoness had a liking to Bella. What was her name... Edelgard? That had to be her name, because Bella would mention about her from time to time. Just her talking about her usual day, but he can see it was starting to become more that her helping Edelgard with her own training.

They look cute together.

Byleth stops his training, using the towel he brought with him to wipe away the excess sweat on his forehead and around his neck. He kinda doubts Zeldris wouldn't mind it, and he was addicted to his natural scent.

'Speaking of which, what's taking him so long...?' Byleth frowned to himself in thought.

Then he suddenly felt a gaze upon him. Byleth looks around with his emerald eyes narrowed. He sees nobody though, which gave him an odd sense of deja vu. Then he turns on his heels, only to have his eyes widen slightly in surprise upon seeing someone he did not expect.

Zeldris' oldest brother, Meliodas.
