Height 167 cm Arcueid Brunestud is the main heroine of Tsukihime, being the eponymous Moon Princess (月姫, Tsukihime). Arcueid is a mysterious vampire princess. She lacks some vampiric qualities, such as that of needing to consume blood to survive (though she suppresses the desire), and being nocturnal. She seems to be quite knowledgeable about many things, but is portrayed as very naïve when it comes to modern ideas. She is killed by Shiki in the first chapter, but she doesn't actually die, having regenerated from her dismemberment, and, in turn, recruits Shiki to help her fight Roa.
