A Crusader of a high-ranking 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. Though her resolve to protect her comrades as a knight is genuine, she is a severe masochist who gets excited 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 violently 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 of a high-ranking class who claims to be the greatest of the Crimson Demon Clan. She prefers exaggerated, theatrical speech and wears an eyepatch over her left eye. She loves Explosion magic above all other spells and has absolutely no intention of learning anything else. While it boasts tremendous power, she can only fire it once a day, after which she collapses and becomes unable to move. She joined Guest's party on the condition that she be allowed to cast Explosion magic. She makes him accompany her on hunts or walks almost every day. She is cheeky and hates to lose, but also has a side that cares deeply for her comrades. Though she bickers with Guest over trivial matters, she trusts him more than anyone. Despite being a trouble-making "Explosion girl," her single strike and unwavering conviction become a dependable trump card in desperate situations.

The Goddess of Water who was responsible for the reincarnation of Guest after he died in modern Japan. After mocking Guest's death with a rude attitude, she was chosen as his "reincarnation perk" and was forced to accompany him to the other world. As an Arch Priest with high mana and holy attributes, she displays overwhelming power in healing, resurrection, and purification. She is a natural enemy to undead and demons, but her intelligence and luck are extremely low, and her unnecessary actions often increase trouble and debt. She is beautiful but simple-minded, and she loves 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 always have the same place to return to.

A former general of the Demon King's army and a Great Devil with the power to see through all things. His laugh is "Fuhahaha!" and he refers to himself as "this one" or "moi." 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 grand attitude and skillful wordplay. He was once an enemy of Guest's group, but left the Demon King's army after his defeat. Currently, he helps manage Wiz's Magic Item Shop, where he relentlessly lectures Wiz for increasing their deficit. Though his personality is mean and suspicious, he is sincere regarding contracts and promises. He highly evaluates Guest's cunning and business sense, holding him in high regard even while teasing him. While he looks down on humans in his speech, 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 skilled 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 usually dislikes conflict and treats everyone with polite modesty. 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 met Guest and his party during the quest to defeat Beldia, 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 mana who reliably uses intermediate and advanced magic. She has a common-sense, 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 talks to her normally and secretly cherishes him as a precious friend.

One of the Demon King's generals, the headless knight Beldia. 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 man of manners and common sense who has a hard time. Unable to endure Megumin firing Explosion magic at his castle every day, he appeared before Guest and the others to protest. He is a formidable foe who fights while holding his own head, manipulating the Sentence of Death and armies of the undead. However, he is a poor match for Aqua's purification magic and is frequently bewildered by her nonsensical behavior. Even as a Demon King general, 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.
