Alpha genes produce people with exceptional appearance, intelligence, and abilities, but only exists in 1/100,000 people.

Nobunaga, born an alpha, will always attract other people. Despite having everything, all he wanted for was "a turn of fate."

After meeting a woman that filled him with a need to have her and only her, the ultimate climax starts!

In the world people are tempted in α, β and Ω. The α are the men who are destined for something higher by birth and by their gene. The β are the same people who live those responsible, who direct and belong to the α. The Ω are actually the perfect partner for the α, since they can give birth with their other α. But since they expel their pheromone, which no one can broaden, they are not very much heard.
Nobunaga is an α. Every β admires him, if he only has contempt for them. His servants have to suffer from his moods. Just just ordered you to move to Brazil so you don't have to see anymore. So he only has three Ran as servants.
Still servants have to be good. Because who are victims of Nobunaga's pheromones.
So like the naive Iyo who just rushes out, who made it out of those connected in Nobunagas. Because for Nobunaga his "rut" begins. And his pheromones are particularly strong because he is looking for a partner.
Iyo's girlfriend Noel will save her and follow her. When she contested Iyo, she was lying half-naked on the ground in front of Nobunaga. Nevertheless, she undressed because of him. When Noel becomes Nobunaga, she quickly becomes moved from his pheromone actions. But then he shrugs back. Because even if you have not decided it, Noel is an Ω and is therefore not easily influenced by the α influence.
But even if Noel can hardly defend herself against Nobunaga's influence, she actually loves her sandpit friend Hiro.
The manga reflected the affection two students who find through their pheromones find they dislike each other. This means that they ward off the affections of the β, their pheromones die.
物語の舞台は、男と女のほかに「α(アルファ)」、「β(ベータ)」、「Ω(オメガ)」という性別が存在する世界。

人口のほとんどはβで、並外れた容姿や能力を持つαは10万人にひとりの割合しか存在しません。そしてΩは“確実にαを産める”とされる繁殖特化型の性ですが、α以上に珍しく絶滅危惧種とまで呼ばれていました。

Ωだということを隠して生きてきたのえるは、ある日αのなかでも特別な存在・ナンバーズである信長に出会い、彼に執着されるようになります。そしてなかば無理やり彼の「従者(サーヴァント)」として、選ばれし人間が通う「安土桃山学院」に通い始めることに。
