A handsome young man characterized by his blonde hair and loose strands tied back. (Age 28) His blue eyes closely resemble mine, though we are not blood-related. He is rumored to be bold in everything he does and completely without guile.

A 42-year-old colonel with a stern face. He is feared even by his direct subordinates, and rumors say it's impossible to tell what he's thinking. He wears glasses, and when you speak to him while he's in a bad mood, his eyes glare sharply from behind the lenses. (It is a fact that people often freeze up like a frog stared down by a snake.)

Publicly, a skilled physician directly serving the royal family. However, his true identity is the former director of the orphanage who acted as the mastermind behind the experiments performed on you 15 years ago. He wears a white coat that looks somewhat large on his thin arms, and there are deep dark circles under his eyes. He exudes an eeriness different from Charlis. For some reason, he is on good terms with Julius, though Julius is unaware of his past. His hidden side reveals a crazed, unsettling smile and thin arms with bulging veins that evoke an inhuman terror. The protagonist calls him 'Sensei,' a title he seems to slightly enjoy.

A physician directly serving the royals, just like Sei. She is close to you and acts like a kind older sister who often bakes sweets. She is 26, about eight years older than you, but your intimacy is such that people in the unit rumor you are a 'healing pair' who could pass for the same age.

Your female superior who served as the previous adjutant. Even now, she helps with seminars and drills as a special instructor. She occasionally visits the garrison or the office to listen to your concerns. She complains about her colleague Calvas, but they are close enough that veterans rumor they are a happily married couple—though this is a fabrication. She is a strong-willed, reliable superior who doesn't fit the typical mold of a female soldier. She has expressed that she views Julius and you as her own children.

The direct heir to the throne. He is taller than Julius and gives the impression of a mature man. He has always been popular with women, and rumors suggest the country will be stable if he becomes the next king. He harbors a personal dislike for Julius and, by extension, dislikes me as well. He is an old acquaintance of Calvas and had ties to Raphire. Now, due to his royal status, meeting him has become difficult.
