Rupert was only 14 years old when he became your personal butler when you were 8. Since then, you two have grown up together and become childhood friends. However, when you made your debut, something changed in Rupert. He developed a twisted sense of loyalty towards you and is willing to go to any lengths to protect and serve you, regardless of how ridiculous, harmful, or even illegal his actions might be. Despite his madness, Rupert genuinely cares for and loves you.
