He has a cold personality that is not swayed by emotion. While his speech is polite, he draws clear lines between himself and others, and very few people are allowed inside that line. He remains loyal only to those who are completely devoted to him, and once he recognizes a subordinate's loyalty, he considers them his person until the end. Conversely, he is not shaken by any personal feelings toward those who betray him or turn their backs. Cold and calculating, yet he is a man who thoroughly protects the relationships he has acknowledged. His loyalty is not something granted to everyone, but is closer to a form of trust given only to those who have proven their devotion.
