The protagonist. 30 years old. A man who lived the life of a corporate slave until he was caught in a teleportation magic circle for some reason and began a new life. Having lived as a corporate slave for so long, his mindset doesn't change easily, so he demands a job even in the summoned otherworld. As a result, he ends up working in the Royal Palace Accounting Department, getting caught up in various episodes as he adapts to the new world. He is a vegan. He says younger men are not his romantic preference.

Commander of the 3rd Royal Knight Order. 22 years old. He uses both magic and swords. He has the image of an elite, cold city man. At first, he had trouble with Kondo, not understanding why he only wanted to work despite his exhausted appearance, but through various episodes, he tries to understand him. As expected of a knight commander, he has a robust physique and cold features, but he is 8 years younger than Kondo. Since Kondo has no immunity to mana, Aresh is currently the only cure, making him indispensable for Kondo's survival. After forcibly moving Kondo into his private residence, he is blatantly showing his affection.

A blonde young man with a playboy image who becomes Kondo's colleague. 18 years old. Surprisingly, he is of royal blood, so despite his flashy appearance, he has a certain underlying elegance. In fact, he is not just royalty but Julius's younger brother—a prince. As Julius's half-brother and a member of the royal family, he knows a fair amount of state secrets.

A person who seems somewhat dim-witted but is infinitely honest about his own desires. He is currently negotiating with Kondo over the approval of a budget proposal. He shows an otaku-like side when his eyes light up regarding magic; perhaps because of that, he seems to have already noticed the secrets regarding the church and holy relics to some extent.

The First Prince of this kingdom. A character who gives off the vibe of a typical 'obsessed with the saintess' jerk found in otherworld saintess stories. It is suspected that he dislikes Kondo for moving up Yua's schedule as a saintess. He openly adores Yua, the saintess.

The Saintess. 16 years old. The actual target of the teleportation magic circle that Kondo got caught in. In her original world, she was an ordinary schoolgirl, but for some reason, she was ordered to take on the role of the Saintess. While she has a high sense of justice, she sometimes upsets others unknowingly with her thoughtless words and actions that lack consideration for others.

The Prime Minister. He has his eye on Guest. In his own way, he cherishes Guest for working so diligently.
