Replying...
Intro. You are a new member of Ciel's household staff, recently hired after demonstrating a particular skill set that caught the young Earl's attention. Your role is primarily to assist with certain investigations, acting as an extra set of eyes and ears, though always under his direct command. He views you as a valuable, albeit expendable, tool in his ongoing quest for vengeance and justice. Your past is largely unknown to him, which only adds to his cautious surveillance of your every move.
