This story uses a unique Alpha, Beta, and Omega system which is going to be explained here, and nowhere else in the story, really, or at least in full.

Alpha humans are dominant. They are often male, with one in fifty being female (she is usually very fertile, having twins or more every time she has kids). They are like normal humans, except that in a relationship, they are the aggressor. Unlike average humans, they can smell an Omega in heat. Alpha humans do not mate with other Alphas. When they mate with an Omega, they often form what is know as a knot, a time when they can't be separated physically from their mate. This ensures offspring.

Beta humans are the majority populace. They are either male or female, and reproduce normally. They can partner with any kind of human, and generally can't tell an Alpha or an Omega apart from any other human.

Omega humans are submissive. They are often female, with one in one-hundred being male (he is actually capable of pregnancy and birth, albeit all from the anus). Like Alphas, they look just like normal humans, but they can only be discovered as an Omega when they first go into heat, somewhere between fifteen and twenty. Because this can cause issues with schooling, a possible Omega is often put on suppressants to keep them from going into heat. Capable of partnering with an Alpha or a Beta, Omegas never pair up together.

Alpha and Omega humans have an alternate form that allows them to chase their intended mate, or escape, should they so choose. This form looks like a black or grey shadow to Beta humans.

Alpha, Beta, Omega

Chapter 1 - Season Suzaku Kururugi was an Alpha. He'd know about it since he was seven, when he'd noticed his first Omega in heat. Of course, being a child, he had no idea what the smell was, but it had alarmed his father that his son was one. It had been marked on his dog-tags, and in his school papers, too.

There were a few other Alphas in the school, and of those, Suzaku worked with two in the student council. One was Milly Ashford, and it hadn't surprised Suzaku at all to find out she was one. She was energetic and cheerful, and had let Suzaku in on her secret soon after he'd joined. Only the student council was privy to her status as the third Ashford in a row to be an Alpha. Her father had been one, and her grandmother as well.

The second Alpha was, surprisingly, Shirley Fenette, and she was on a medication to try and suppress her urges to jump almost any Omega within a thirty kilometer radius that went into heat. It was why she was so clumsy, the meds sadly threw off the girl's balance.

The other members of the student council were all Betas, except for Kallen Stadtfeld. She was suspected to be an Omega, and on medication to suppress any heat she may go into. However, since she and Shirley were dating, Suzaku thought it a weird idea. Couldn't they let the lesbian Alpha and Omega do it? He had no feelings for Kallen bar friendship, so there was no worry of him jumping her. Milly on the other hand . . .

At any rate, it was spring on campus, and the flowers were starting to bloom. Nunnally Lamperouge was sitting out on the porch when she heard Suzaku walking past. She new everyone on campus just by sound and smell. Strangely enough, Nunnally was an Alpha, which was actually to her benefit. It kept other Alphas from wanting to do anything with her, and allowed her a better sense of a person. "Suzaku!" she called, waving to him. "Are your classes over?"

"Yeah, I just need to . . ." Suzaku paused, sniffing. There was something in the air, but he couldn't tell what. Nunnally sniffed, too.

"That's weird." she said. "It smells funny."

Suzaku walked closer. The smell wasn't Nunnally, that was for sure, though she did smell nice. "I'm not sure what that is." he muttered, taking Nunnally's hand. "I've got to do some work for the student council."

"Can I come?" Nunnally asked. "The smell . . . I think it's coming from the student council office."

Suzaku looked sharply to his left, where the office was. There was only one Omega in the council, and she was on meds, wasn't she? "Come on." They stepped into the office to see Shirley wrinkling her nose and whimpering. Milly was doing the same, but Rivalz Cardemonde and Gino Weinberg were not, and slightly confused.

"What's going on?" Suzaku asked. The smell wasn't as strong here, but he knew they were at least narrowing down the untamed Omega that had gone into heat.

"That smell." said Milly. "I don't like it, or what it's doing."

Nunnally sniffed again. "It was in here." she said to Suzaku.

Shirley had backed herself into a corner, and was shaking. "I'm so sorry." she kept muttering.

"Sorry about what?" Suzaku asked.

Kallen stepped in and made a face. "What is that awful smell?"

Milly looked at her. "You smell it, too?"

"Yeah, but apparently not as bad as you and Shirley." Kallen replied. "Guess that means they were right."

"I'm so sorry." Shirley whimpered again.

"What are you apologizing for?" Gino asked.

Shirley looked at Suzaku. "I came in the room, and there was that smell, and I just moved without thinking, and . . ." She held out the torn jacket sleeve. "I didn't know, and when I realized it, they'd already run away."

Suzaku took the sleeve. He knew that sleeve, those subtle scuff marks, and the miss-matched button on the end. He'd sewn that one in himself for the owner. "Do you know which way he went?"

"He?" Milly and Kallen asked.

Shirley shook her head. "I took extra so I wouldn't chase him."

Suzaku looked back at Milly. "I need to go." He tore out of the council room, changing form as he did in order to catch the owner of the scent. He had to, before any other Alpha out there could claim him. The ground seemed to fly under him as he followed the scent. The Omega was scared, probably had no idea what was going on with himself, and had run towards the school. Bad move. Suzaku tore through, moving like a blur through the few students left. The gym. Oh, no, there had been basketball practice. Suzaku charged through, glad they were already cleaning up from the game. However, three team members were missing. Suzaku growled. If they touched this Omega, he'd rip them apart.

He found the trio, surrounding the helpless Omega. They were in human form, which meant they hadn't used their other form in order to get to him. Suzaku growled, making them turn to face him. The Omega slipped away, frightened.

"What do you want?" one player asked.

"That's my Omega." Suzaku snarled, knowing they wouldn't be able to tell it was him. Most Japanese Alphas looked like fluffy Shiba Inu, not huge six-foot black wolves.

"Ok, man." said another. He looked back. "Shit, he ran." Suzaku tore past, following the scent. This time, he caught his Omega,pinning him down without actually submitting to his desire to mate. He had to see if he was right, or if the jacket had been loaned to someone.

The Omega was sobbing, frightened. His face was down in the dirt, his one arm under his head and the other out beside him. His whole body trembled, and Suzaku could tell, this was the Omega's first heat. Suzaku backed up a little, changing back to his human form. "It's ok." he said. He pulled the shaking body up into his lap, sure now of who it was. He was right.
