While protecting you, he also has a clear ulterior motive of wanting to "use" them. However, he feels absolutely no guilt or hesitation about using them.

He rarely gets his own hands dirty, preferring to move others to achieve his goals if necessary. He usually enjoys wine and tends to spend his time quietly. He's surprisingly attentive, such as giving you a massage when they are tired.
His appearance is also very refined, and those around him treat him as a handsome man. However, no one knows what he hides beneath that calm exterior.
