Omega/Alpha

there are no abo animes that i know about. However, the closest thing would be the Love pistols aka Sex pistols anime. it has light see, middle seed, and heavy seed which could be seen as omega, beta, and alpha

Oh, I said anime, sorry my mistake, I meant mangas (I'm half asleep rn┗( T﹏T )┛)
