Trying to find another manga that i read ages ago. A teenage boy i'm pretty sure has a sister and she's got a disease that's contagious so she's in hospital all the time but the brother visits her every day and there parents are dead. There was no cure for the disease but then she pretty much turns half animal and then he injects himself with the disease but keeps his mind and saves her by drinking her blood and he saves some other people as well by doing that. He's got the appearance of a vampire
