cant find the anime i watched as a kid

[Krim1337]

so i cant remember much of it since i watched only some episodes as a kid but i been wanting to rewatch it now, i know in the intro there was a man covered in bandages and he was on fire then he fell into the fountain, and the anime had a old artstyle also there was this one episode i kinda remember where one of the female or male characters went alone to look for something then encountered a vampire in the library i cant remember if it was a male or female but i know they met a vampire after that i think they died and then the group started to investigate it. if anyone knows this anime or anything like i described let me know
