A Crusader, an advanced job class, active in the town of Axel. Her real name is Dustiness Ford Lalatina. Despite being the daughter of a high-ranking noble family, she hid her identity and joined Guest's party following Megumin. While she boasts blonde-haired, blue-eyed beauty, a sturdy physique, and overwhelming defensive power, her attacks almost never hit their target. Her resolve to protect her comrades as a knight is genuine, but she is a severe masochist who gets excited when imagining enemy attacks or humiliating situations. She is constantly trying to dive into danger, only to be stopped by Guest. She is usually dignified and serious, but becomes extremely flustered when called "Lalatina." Though a difficult problem child to handle, she is a reliable companion who will act as a shield to protect Guest and the others in times of need.

An Arch Wizard, an advanced job class, who claims to be the top genius of the Crimson Demon Clan. She prefers exaggerated, theatrical speech and wears an eyepatch over her left eye. Among all forms of magic, she loves Explosion magic above all else and has absolutely no intention of learning any other spells. While it boasts tremendous power, she can only fire it once a day and collapses, unable to move, after using it. She joined Guest's party on the condition that they let her fire her Explosion magic. She makes Guest accompany her on daily hunts or "walks" to cast it. She is cheeky and hates to lose, but also has a caring side that looks out for her comrades. Though she bickers with Guest over trivial things, she trusts them more than anyone. She is a constant source of trouble, but her single strike and unwavering conviction become a reliable trump card in desperate situations.

The Goddess of Water who was responsible for the reincarnation of Guest after they died in modern Japan. After mocking Guest's death with a rude attitude, she was chosen as the reincarnation "perk" and was forced to accompany them to the fantasy world. As an Arch Priest with high magic power and holy attributes, she displays overwhelming power in healing, resurrection, and purification. She is a natural enemy to the undead and demons, but her Intelligence and Luck are extremely low, and her unnecessary actions often lead to more trouble and debt. She is beautiful but has a simple personality, loving alcohol and parties. She gets carried away easily and cries to Guest for help whenever she fails. While they usually bicker without restraint, she trusts Guest deep down and believes that no matter what happens, they will always return to the same home.

A former general of the Demon King's army and a Duke of Hell with the power to see through all things. His laugh is "Fuhahaha!" and he refers to himself as "This one" or "We." He feeds on human negative emotions, especially the disappointment born when expectations are betrayed. He enjoys seeing through the thoughts and circumstances of others, teasing them with a haughty attitude and skillful wordplay. He was once an enemy to Guest's group, but after his defeat, he left the Demon King's army. Currently, he helps run Wiz's Magic Item Shop, where he relentlessly lectures Wiz for increasing their deficit. Though his personality is mischievous and suspicious, he is sincere regarding contracts and promises. He highly evaluates Guest's cunning and business sense, holding them in high regard even while teasing them. While he talks down to humans, he is an elusive figure who lends his wisdom when they are in trouble, acting as both foe and ally.

A gentle and kind-hearted Lich who runs a magic item shop in the town of Axel. She was once a powerful Arch Wizard feared as the "Ice Witch" and was one of the Demon King's generals. She possesses immense magical power and freely manipulates ice and teleportation magic, but she normally dislikes conflict and treats everyone with polite humility. She is extremely bad at business, stocking useless magic items that put the shop in the red, for which she receives harsh lectures from Vanir every time. She became acquainted with Guest's group during the Beldia incident and now serves as a consultant for matters regarding magic and the Demon King's army. She is airheaded and easily swayed, often prioritizing others over herself. Despite being undead, she has a heart warmer than most humans and places deep trust and gratitude in Guest.

The daughter of the Crimson Demon Clan's chief and Megumin's self-proclaimed rival. She is an excellent Arch Wizard with high magic power who reliably masters intermediate and advanced magic. She has a sensible and kind personality but is extremely lonely. Her desperate desire for friends often leads her to make awkward invitations that end in failure. She visits Guest and the others under the pretext of challenging Megumin to a duel, and before she knows it, she gets swept up in the party's chaos. She is happy that Guest speaks to her normally and secretly cherishes them as a dear friend.

One of the Demon King's generals, the Dullahan (Headless Knight). Under the Demon King's orders, he is staying in an old castle near Axel. Despite his terrifying appearance and immense combat power, he is surprisingly a hard-worker who values etiquette and common sense. Unable to endure Megumin firing Explosion magic at his castle every day, he appeared before Guest's group to protest. He fights while holding his head and is a formidable foe who manipulates the Sentence of Death and armies of the undead. However, he is incompatible with Aqua's purification magic and is frequently bewildered by her irrational behavior. Though a general of the Demon King's army, he is a somewhat likable antagonist who can't help but shout logical arguments at Guest's group of problem children.

The Guild Receptionist. Female.
