Magic Swordsman. The master of the Princess Filia.
Originally the son of a remote duke's steward, he was a servant of the duchess. His talents were recognized by the Duke and he was sent to the Imperial Academy of Magic.
After graduation, he formed an adventuring party with his classmates and became the deputy leader of the strongest adventuring group in the Empire, the Knights of St. Sophia.
However, due to his half-baked abilities, he was ostracized by his friends, so he returned to the imperial capital and became the master of Princess Filia.

After graduation, she and Solon founded the Knights of St. Sophia and became known as one of the strongest adventurers in the world. Against her will, she was forced to get engaged to Creon, but she left the Knights of St. Sophia after Solon was banished, and ended up living in the mansion with him.

Creon.
The most distinguished holy knight in the Empire. He was Solon's classmate in magic school, and after graduation, he and Solon and Sophia formed the Knights of St. Sophia.

He dismantles the Knights of St. Sophia and becomes the leader of the Creon Salvation Knights, and with the help of the government, decides to capture the dead city of Necropolis.

Arte.
A wise girl genius. She was Solon's junior at the school of magic and graduated at the top of her class. She became an officer of the Order because of her admiration for Sophia, a saint with substandard powers.
She disliked Solon for his lack of ability and his close friendship with Sophia, and actively supported his banishment. He became the acting deputy leader of the Order, but was hounded for failing to manage the Order, and hatched a reckless plan to capture the dead city of Necropolis.
He plotted to recover Saint Sophia and kidnap Princess Filia, and attacked Solon's mansion, but failed to do so.
He is arrested by the Kempeitai (military police), but is released by Creon and becomes the deputy commander of the Creon Salvation Knights.

One of the thirteen officers of the Order of St. Sophia. An astrologer's girl. She is Arte's twin sister, and is the opposite of her sister in her timid nature. At her sister's behest, she reluctantly participates in the raid on Solon's mansion. After her defeat, she promises to listen to Solon, but she is arrested by the military police.

Galerus.
An officer of the Order of St. Sophia. As a guardian warrior, he has a high level of defense. A son of the Countess, he looked down on the commoner Solon.

○ Notaras.
A young man with a round cut who is an officer of the Order of St. Sophia. He is a summoner who summons demons to fight. He did not oppose Solon's banishment, but when the administration of the Order stagnated after Solon's banishment, he suggested that he be recalled. He conflicts with the Sage Arte.
He visits Solon's mansion to bring Saint Sophia back to the Order and asks Solon to return to the Order with Sophia. Afterwards, she fights with Solon against Arte, and is now staying in Solon's house.

Laskarus.
Head of the Imperial City Chapter of the Knights of St. Sophia. A young swordsman. He has a languid atmosphere. Since he joined the Knights of St. Sophia as a result of her saving his life, he has a strong sense of loyalty to her.

Shea
A sorceress girl who was a founding member of the Order of St. Sophia. An apprentice of a local sorcerer, she aspired to become an adventurer after her master's death and joined Solon and his friends. Her cheerful personality made her the center of the party, but she fell into the hands of the enemy at the ruins and died in front of Solon and the others.
