Hallelujah and The Succubus!

Hallelujah Tendo, a veterinary student renowned for his honesty, is affectionately known as the "angel of the veterinary faculty." His reputation is put to the test when he encounters a mysterious creature with bat-like wings, revealed to be the demon Lucif, who has been banished from heaven by the angel Micha. Moreover, Lucif has been implanted with a succubus seed, which makes him incredibly susceptible to intense craving. When Hallelujah touches him, Lucif's repressed desires are triggered, and he impulsively demands that Hallelujah satisfy his extreme hunger. Caught off guard, Hallelujah is left stunned and violated, only to be further complicated by the discovery that he is now bound to Lucif through magical collars and chains. This new and unsettling reality forces Hallelujah to frequently provide for Lucif's carnal needs, all while the demon slowly regains his strength. As Lucif's powers return, his fellow demon, Baal Belial, becomes aware of his presence and sets out to reclaim him, setting the stage for a tumultuous and transformative journey for Hallelujah.
