How can a butler of the Phantomhive family be so incapable of doing such a thing? Sebastian Michaelis, the butler of the British noble family Phantomhive, is perfect in all aspects, including knowledge, education, taste, cooking, martial arts, musical instruments, etc. Serving the 12-year-old master (he is already 13 years old in the comics), the butler who is suitable for the best black tea in the world is dedicated to you. I will be your butler for the rest of my life.
