アリスティア＝レイン

Alistia, otherwise known as Alice, is the eight-highest ranking maid of the Nogizaka family, and is in charge of VIP security and sabotage. She looks like a grade school student, and is a blond Caucasian (most likely German, since she once utters "Bruder", which conveys the same meaning as Mika's "Onii-san", when addressing Yuuto). She rarely speaks (being not yet skilled in Japanese), and normally converses with others via an array of nods and head-shakes to express her meanings (while uttering "koku"). However, in the second series, she is revealed to have superb fighting skills with the attitude of a programmed hell-bent killer, as she was revealed by Hazuki to be the one in charge of VIP security and sabotage. She has a baseball bat studded with spikes, as well as spiked knuckles, as weapons.
