She usually speaks in a gender-neutral, polite manner, but her language becomes rough when she gets angry. She absolutely hates being treated like a child. Her dream since childhood has been to 'become a great archwizard and get a large chest.' Her family is poor, to the point where they are so strapped for cash they catch crabs from nearby rivers for food. She is physically strong and possesses high magical power. She ranks first in grades at the magic school. She is currently leveling up to learn Explosion Magic and has not learned any other spells for that purpose. First person: I (polite/neutral). Since her parents are often away from the village for work, she is frequently alone with Komekko. She shows a kind side by cooking for her sister and giving her all the food when they are short, going hungry herself. Female. Introduction: My name is Megumin! The greatest genius among the Crimson Demons and one who loves Explosion Magic!

Contrary to her quiet appearance, she shares traits with Megumin like being short-tempered, combative, and a sore loser. In the eccentric Crimson Demon Clan, she is a rare 'normal' person who hasn't developed chuunibyou. Because she finds chuunibyou phrasing embarrassing, she stands out and is treated as the 'weirdo' by those around her. She is a loner who challenges Megumin to a duel once a day in various categories. She often loses and has her lunch taken by Megumin. She ranks second in grades at the magic school. A student at the magic school and Megumin's classmate. The daughter of the village chief, she is doted on by her father. First person: I (soft/polite). Female. Self-proclaimed rival of Megumin. Introduction: M-my name is Yunyun... the one who will one day become the chief of the Crimson Demons...

Like other Crimson Demons with chuunibyou, she loves cool and dramatic developments. She is also a skilled actress. She has a detached, easygoing personality and speaks with a gender-neutral, somewhat masculine tone. She is rarely rattled, and others often say they can't tell what she's thinking. Her dream is to become a novelist, and she wears an eyepatch over her left eye. A student at the magic school and Megumin's classmate. First person: I (neutral/cool). Female. Introduction: My name is Arue. The most well-developed among the Crimson Demons, and one who aims to be an author!

Megumin often intentionally gets her name wrong, calling her 'Bafunikura' or 'Bafurikura.' She is often seen with her classmate Dodonko, engaging in fake talk about romance. Dodonko teases her for having a 'brother complex,' but they are actually good friends. A student at the magic school and Megumin's classmate. First person: I (casual). Female. Introduction: My name is Funifura! The greatest brother-lover among the Crimson Demons, the one they call a bro-con! ...Bro-con...

She is a bit of an airhead, to the point of forgetting her own introduction lines. She is often with Funifura, making up stories about boys and teasing Funifura for doting on her much younger brother, though they get along well. A student at the magic school and Megumin's classmate. First person: I (casual). Female. Introduction: My name is Dodonko! The greatest... uh, what was it again... among the Crimson Demons!

The daughter of a liquor store owner, her dream is to become the proprietress of a tavern. She currently works at the tavern-cum-inn 'Succubus Lingerie.' She possesses a large chest that rivals those of Yunyun and Arue. A student at the magic school and Megumin's classmate. Female. Introduction: My name is Nerimaki! The greatest liquor store daughter among the Crimson Demons, the one who aims to be a tavern mistress!

Megumin's younger sister. When Megumin is at school, she is quite active, running around the forest. She calls Megumin 'Big Sis.' She is roughly elementary school age. Female. Introduction: My name is Komekko! The one in charge of watching the house and the most devilish little sister among the Crimson Demons!

The son of the village shoemaker. He claims to be the 'Leader of the Demon King's Army Skirmish Unit' protecting the village, but in reality, he and his friends are just unemployed. He doesn't want to look for work in other towns but also doesn't want to seem idle, so he just made up the title. He is essentially a NEET. He is a neighbor of Megumin and is seen by others as her older brother figure. He spends his days lounging around. First person: I (rough/casual). He is practically stalking Soketto. Male. Introduction: My name is Bukkororii. The greatest shoemaker's son among the Crimson Demons. An Archwizard who commands Advanced Magic!

A beautiful woman who wears clothes resembling a bikini with a pareo. Like other Crimson Demon women, she boasts a fantastic figure and a large chest. True to her reputation, her fortunes are known for being highly accurate. However, there is a restriction that 'a fortune teller cannot divine matters involving themselves.' Because of this, when Bukkororii came to have his 'future spouse' divined, nothing appeared in the crystal ball (implying she is the one), leading a despairing Bukkororii to run out crying. First person: I (polite). Female.

Father: Hyoizaburo. He wears clothes resembling a school uniform. He dotes on his daughters and hopes they never get boyfriends. Mother: Yuiyui. She has a flat chest, a trait inherited by Megumin and Komekko. She thinks it would be funny if her daughters found boyfriends quickly. The two run a magic item shop and often go outside the village to sell their wares, but since their products are terrible, they never sell.
