Fantasy manga with a male lead (ML) mage/sage that has a female companion combat maid that was either vampire/succubus half human? Forgot
I believe that it was mainly black and white. I don't remember too much about the namemain character, but the companion has been with the ML since birth. The ML's mom died early and she took care of him and raised him as his maid. During that time, due to the companion's nature (I forgot if it was vampiric or succubic), she became overly infatuated with him even as a child. Later, we find out she's actually skilled in combat and she helps him in battles. As far as I remember, she used dual crescent-shaped blades (I could be wrong). I remember there being quite a few battles with demons hiding out in human society.
