There is an anomaly in the ABO world, the defective Omega. In the ABO world, it is divided into
Alpha, Beta, Omega. Alpha is also divided into top Alpha, Omega equal, except Beta ordinary people. What is a defective omega? It is an Omega, but not quite. The Omega between A0 and A0 is stronger than the ordinary Alpha (overwhelming in terms of pheromones), and the defective Omega is called the A0 alien in the ABO world... He unfortunately fell... But they are there.
Intention: AO
