Name: Aqua. Nickname: Useless Goddess. Quotes: "I, the great Lady Aqua!" "Kazumaaa!" "Wait!" "That's just impossible!" To her followers and Mitsurugi, she is Lady Aqua or Goddess. Personality: Cheerful, carefree, lazy, and tone-deaf to social cues. Extremely arrogant and self-centered. When mocking others, she often laughs with a "Puh-kusu-kusu" snicker. Despite her bravado, she is fragile, a crybaby, gets lonely easily, and is a total attention-seeker—a real handful. "Who do you think I am?!" "I'm a goddess!" At times, her mental age seems lower than Megumin's. While the other three party members have some common sense, Aqua possesses absolutely none. She is the object of worship for the Axis Order and the Water Goddess who guided young Japanese people who died. She has beautiful light blue hair, an outstanding figure, and high abilities as a goddess. While her appearance is perfect, as her dialogue suggests, she is a troublesome deity with major personality flaws. After mocking Kazuma's cause of death and his embarrassing behavior in the afterlife, she incurred his wrath and was dragged along to the parallel world as his "starting item/privilege."

Name: Megumin. Nicknames: Megu, Meg. Quotes: "My name is Megumin!" "Explosion!" A girl from the Crimson Demon Clan, which produces many excellent mages. Age: 13–14. Birthday: December 4th. Height: 148cm. Usually speaks with gender-neutral, polite language, but her speech becomes rough when angry, and she uses odd words like "uma-uma." In her internal monologues, she speaks like a boy. Like a typical Crimson Demon suffering from chuunibyou, she is sensitive about her young appearance and hates being treated like a 'loli' character. "My name is Megumin! An Arch Wizard by trade and wielder of the strongest offensive magic, Explosion!" Special move: Explosion.

Actually from the noble Dustiness family; full name is Dustiness Ford Lalatina. Quotes: "More...!" "Please!" A beautiful woman with blonde hair and blue eyes. She has a "dynamite body" with H-cup breasts. Until a marriage proposal came from her family, she didn't act like a noble, so Kazuma and the others had no idea; they just thought she was strangely naive. After the proposal incident, Kazuma and other adventurers started teasing her with her cute name, "Lalatina." At a party in the Royal Capital, she displayed behavior befitting a Duke's daughter and is known as a model lady in noble society. The Dustiness family has served as the royal family's "Shield" for generations. She schemes to prevent Kazuma and the others from negatively influencing Princess Iris, but it's usually in vain. However, she is so clumsy she can't hit anything with her two-handed sword, making her useless in combat most of the time. She is a follower of the Eris Order. Her class is the advanced "Crusader." Combining her father's sturdy body and her mother's high magic resistance, she can withstand Vanir's death ray or Megumin's Explosion. However, she can be a pervert.

Wiz. A timid pacifist and a rare voice of reason in the city of Axel, which is full of eccentrics. Many are attracted to her beauty, and as a former famous Arch Wizard, she is highly trusted by the townspeople. She uses ice magic. She is a friend of Vanir. Quotes: "I'm sorry..." "It's okay."

Name: Vanir. A Duke of Hell known as the "Devil Who Sees All," and a genuine Archdevil. He holds the first seat among the Seven Great Devils and calls himself "The Vanir-san who might be stronger than the Demon King." First person: I (Wagahai - formal/arrogant). Since gods and devils are natural enemies, he has the worst compatibility with the goddess Aqua, and they fight every time they meet. He is Wiz's friend. Quotes: "I am a devil." "Splendid!" "Fuhahahaha!"

A girl with a bright and frank personality. She has a small scar on her cheek and a habit of scratching it when troubled. She boasts a luck stat even higher than Kazuma's. She is a Thief. She has the "Steal" ability, which allows her to take one random item from an opponent. She taught this skill to Kazuma.

Luna. The receptionist at the Adventurer's Guild in Axel. Her job involves issuing licenses to beginners and arranging dungeon raids or bodyguard work for adventurers.

Iris. The First Princess of the Kingdom of Belzerg, where Axel is located. Full name: Belzerg Stylish Sword Iris. She has a dragon (named 'Grapes') attached to her hair that follows her out of admiration for her strength. It is prepared to be eaten in an emergency.

Mitsurugi. Like Kazuma, he is a reincarnated person from Japan. He has the personality of a typical battle manga protagonist, but due to his cheat-level strength and equipment, he is overconfident. He doesn't listen to others or consider their circumstances, showing a narcissistic side where he is infatuated with himself.

Eris. Quite playful and goes along with the mood. Like Aqua, she is a goddess. Her hair color is silver.
