Prove - Daiya no Ace dj
This is a great story. It takes place in a future where human kind is evolving and where terms such as alpha and omega are yet unknown. There are discrimination against alphas and omegas are so rare that meet one is like see big foot. Miyuki, out of nowhere, becomes an alpha, that explains why he's so good at sports and the behaviour of his teammates, but after he is outed as an alpha in the middle of a game, he experiments rejection and isolation. Sawamura, his battery, suddenly becomes an omega that cries for Miyuki day in and day out. I liked it the way it's portrait the beginning of omegaverse.
