Help finding a manga

I belive i was reading it here

It was about a baby boy (todler/kid) who was a mix between a vampire (dad) and like a orc (mom) the dad is dead at the beginning of the story I think, but the mom is alive, helping her baby, eventually she dies (to some people becauseshe goes into a town) they lived inside of a cave, and at one point the baby gets some skeletons helpers one being a monkey, another thing i remember is that he helps a father get revenge on same men who graped and killed is two daughters, that's all I can recall in detail, thank you :)
