Sylvie is a female character who appears on episode 5 "Moonlight Rambler". She and her friend Anri escape and crash-land near Megatokyo. Upon reaching the metropolis, Sylvie befriends Priss without revealing her origin. It is revealed that she is a Sexaroid (a Boomer designed to be a love-doll) model 33-S designed to feed on human blood and pilot "D.D.", a heavily-armed mecha with a fail-safe mechanism that can set to self-destruct if the pilot's vital signs reach flatline. Priss is left no choice but to kill Sylvie to deactivate the D.D.'s self-destruct mechanism.<br /><br />
