Immortal Hounds Vol. 6 (manga)

In an alternate world everyone is an immortal. There are no doctors or hospitals. Cemetaries are things of the past; some consider them to be legends or myths. But with immortality comes consequences, like the loss of some of humanities greatest gifts...including love. There are those who understand that and choose to die for the ability to experience such emotions again. The government is determined to erradicate those who take that path, however.
