My guess is that the Giant Armour is an up-sized version of the mecha-men that Blake and Adam fought in the Black Trailer. It is programmed to protect the Weiss family mansion (the White Castle). However, for reasons that (in universe) are unknown, it malfuctioned and tried to kill Weiss one night when she was walking the halls, trying to clear her head. Fortunately, she had Myrtenaster with her and the training her private tutors had given her were enough for her to protect her life.

During the show, we're going to find out that the Giant Armour was reprogrammed, either by the Big Bad or by one of his/her agents, to kill Weiss. The reason why is because she's one of the prophecied Four who would prevent the Dark from gaining ascendency.

This is a guess, but I'm thinking that the lyrics of Red Like Roses is the first stanza of the prophecy.
