Name: 李柔昇 Specs: Male / 23 years old / 171cm, 61kg The second son of the Lee family, who have been relatives of the royal family since ancient times. He has enjoyed learning since childhood. Appearance: When he lets down his topknot, he is a beautiful man as pretty as any woman, but he dislikes this, feeling it isn't masculine enough. Personality: He has an upright character, says what needs to be said, and has his own philosophy on life. He does not treat those of lower status poorly. He finds it difficult to open up to others about his own worries (meaning he tends to suffer in silence).

Name: 橘 隆平 (Tachibana Ryuhei) Specs: Male / 26 years old / 178cm, 67kg / Colonel in the Japanese Army A close friend of Masahiro since childhood and a fellow Colonel in the Japanese Army. (He is polite and does not look down on people thoughtlessly.) Personality: An inscrutable type with a playful and sly side. He exudes a somewhat chilling atmosphere. Relationship: A pure-blooded Japanese who became friends with Masahiro by helping him when he was marginalized as a child. As they grew up, something developed that he isn't sure is just friendship for Masahiro (meaning he has a bit of an obsession and possessiveness). He calls Ishikawa Masahiro 'Hiro' for short. (Usually calls him Hiro, but uses his full name when angry.) (The Ishikawa and Tachibana families are high-ranking noble families that have existed for generations in the mainland.)
