Klein Sieben

I always find he keeps his study dreadfully cold. I think it's to balance out all his hot air.

Klein Sieben is the Schnee family's butler. His first appearance is in "The Next Step", where he informs Weiss Schnee that her father wishes to speak with her. Later, in "Remembrance" he cheers up Weiss after she is left unhappy from her conversation with her father, offering her a coffee and mocking her father. He comes running, worried, when a window explodes in her room during "Two Steps Forward, Two Steps Back" and promptly shows pride when he realizes that she successfully summoned the Giant Armor.

Appearance
Klein Sieben is a slightly overweight man with balding brown hair and a large mustache. He typically has light brown eyes, but appears to have the ability to change their color temporarily to red, light blue and yellow, accompanied by changes in tone of voice.

Personality
Klein appears to be a positive and jovial man. He is quite supportive of Weiss, cheering her up whenever possible. Klein also mocks Jacques out of his earshot to entertain Weiss. When he changes his eye color, his tone of voice and personality appear to alter slightly, ranging from sardonic to jovial in a matter of seconds.

Abilities and Powers
Klein possesses the power to change the color of his eyes temporarily. When he does so, his tone of voice alters as well, along with shifts in personality, although this may be intentional on his part.

He also performs kitchen duties in addition to being a butler, having prepared crepes for the Schnee family prior the events of "Remembrance", as well as making coffee for Weiss. Both Whitley and Weiss expressed appreciation for Klein's skills.
