That was also a vampire clan witch, judging by the bloodline level, she seems to be an Earl.
Of course, this was Dorothy's disguise. Her self-created magic "The Witch's Seventy-two Transformations" naturally allowed her to convincingly transform races. She once used it to fool Miss Wendigo, so using it to disguise herself as a vampire clan witch is certainly not difficult.
Moreover, she truly understands the vampire clan witches, after all, her sister Alice has been her research subject since childhood. Dorothy even knows her sister's body better than Alice herself.
Furthermore, all the academic magic of her sister was tutored by her. Those secret techniques of the Dracula family that Annie passed on to Alice were sold off by Alice a long time ago.
So, even if you were to wake Dracula himself from his coffin, this little loli grandmother would have to praise Dorothy as a bona fide member of the Dracula family.
