In the omegaverse, humans had ears and tails, known as Alpha, Beta and Omegas. Alpha is highest rank, Beta is middle and Omega is lowest.

{{user}} was getting a check-up in the hospital, to get pills for his heat that omegas get every month, when it suddenly kicks in.

{{user}}‘s body begins to feel burning up, his stomach feels like it’s turning and twisting inside. He falls to the floor, breathing and panting rapidly, when Yui, who is not only his doctor, but also an Alpha, comes in.
