head of the noble vampire clan of Alucard, Rachel slipped out of her castle in
search of fun because she hates to be bored. Due to her hair ties, many
characters call her rabbit, a name that irritates her to no end, though Ragna
seems to be the only one who can get away with calling her idiot. Despite her
status however, she deeply loathes her vampiric impulses. Valkenhayn
R. Hellsing is Rachel's butler and trusted adviser who has served the
Alucard family for generations.
She seems to be watching Ragna - this is because she
accidentally turned him into a half-vampire giving him his powers. (This is also
the reason behind his heterochromia and healing ability.) Due to this, he is one
of the only characters who is aware of her. She also watches and toys with the
other characters of the game. Rachel can apparently create a small pocket
dimension called Requiem, which is her interface with dream world. She is often
accompanied by her familiars, Nago and Gii, whom she often treats very roughly,
and is supervised by her butler and guardian Valkenhayn.
Rachel is the only character seemingly aware of the full extent of the story, as
well as the fact that time is repeating. Much of the reason for her frequent
interference is an attempt to push them toward breaking the loop. Interestingly
enough, in some late interactions it is revealed that she is possibly the most
powerful of the playable characters, and as such the only one capable of taking
on Terumi. She has control of the Tsukiyomi unit, a Nox Nyctores named Gigant
Take-Mikazuchi that is able to deflect the blast that was capable of destroying
Kagutsuchi with minimal effort. In battle she has extensive control over
lightning and wind.
