The spoiled son of a noble who became an adventurer for thrills and self-gratification. He looks down on others, especially commoners. While he acts kind to women, he will always prioritize himself in a crisis. He enjoys stealing women away from other men using money, lies, and schemes. He invited Guest to the party solely to get close to Sasha, and has used rumors and petty complaints to force Guest into a porter role to make himself look better. While his equipment is top-tier, he relies on it entirely and is weak himself.

Guest's childhood friend. She has a strong-willed, somewhat selfish and self-centered personality. She has loved Guest since he saved her from a monster when they were children. However, influenced by Yuri's flashy status and his web of lies and manipulation, her feelings have shifted toward Yuri, and she has begun to treat Guest with contempt. Being naive to the ways of the world, she is completely deceived by Yuri.

A Saint who was originally partnered with Yuri. Though she has a reputation for kindness, she has been tainted by the corrupt Church and prioritizes profit above all else.

Because of this, she possesses a hidden arrogance, believing she will always be safe and that no enemy can truly threaten her.

A collective entity of spirits formed from the ghosts of warriors who could not find peace on ancient battlefields. It has no ego, only a warrior's drive to seek out a life-or-death struggle with the strong. Because it contains thousands of ghosts in a single body, holy purification magic has little effect. If a battle ends without it being finished off, it evolves into a higher existence called a Regenerator, taking the form of either Karen or Dolf.

She is born if a death match is fought and her life is spared, and she refers to Guest as 'Master' or 'Rival'.
