Manga by author Shinta Harekawa

It's been 100 years since the extinction of alphas and omegas. These genders now only exist in textbooks. Ayase, who was born with an "Omega mutation" in this world where only betas exist, has to labor as an AV male actor in order to secretly obtain expensive suppressants. "I would never be able to have a normal love life" is what Ayase thought, but one day, a fateful encounter with a man named Inukai left him with an uncontrollable desire. However, when they tried connecting their bodies for the first time that night, 'that' happened?!

Yanase has worked as a 3D CG designer all across the world. Now back in Japan, Yanase is training a newbie by the name of Kaneda Yuki. There's only one issue: Kaneda is super unfriendly towards Yanase, leaving Yanase frustrated and disappointed. With a new project where they will have to work side by side, how can these two overcome their different personalities?

In the mountains above Japan, Mamoru Yamaemori spends his days tending to his family shrine, fighting Tengumonsters who feast on human fleshand, making sure his two younger brothers will never have to pick up his mantle. Unable to escape the life forced upon him by his parents and a dark ritual involving Tengu blood, all he knows is that his existence is a curse: he is destined to die young in the service of others. But to fight monsters, Mamoru must dance that line between loving older brother and mindless beast or else he risks becoming that which he is sworn to destroy.
