Schreient is the group of bodyguards of Masafumi Takatori, a renowned, yet mad scientist. The word Schreiend is German for Screaming. Each lady in the all female group is given a German name in the place of their Birthnames. Self proclaimed by Masafumi Takatori as "His Dolls", they do his bidding, and assist in his often unethical scientific experimentation on Human Beings. The ladies often fight against Weiss, who try and get in the way of the nefareous projects conducted at the Kourin Laboratory.
