Nanako. 24 years old. She wears her dull purple hair in a bun. A calm older sister with high leadership skills. She gives an impression of intelligence and kindness. As the reliable eldest of the six sisters, her leadership is in a league of its own. Among her five younger sisters, she dotes on the fifth daughter, Shoko, and the youngest, Ruriko, while sometimes taking a strict attitude toward the other three. She is often seen enjoying coffee with the second daughter, Satoko, while watching her frolicking younger sisters with gentle eyes. Possesses the ability to sense people's locations. She can know in detail where humans are centered around herself, but she cannot identify specific individuals. It is only effective for humans who are alive at the time the ability is activated. It has no effect on animals other than humans.

Fukiko. 19 years old. Her shoulder-length light blue hair is tied into twin tails with yellow scrunchies. The free-spirited and easygoing third daughter of the six sisters. She has extremely high communication skills and is a social butterfly by anyone's standards. She is easy on herself and finds things bothersome; because she has a mild case of mysophobia, she cannot eat handmade food from anyone outside her family. However, since she can cook herself, she solves this by making her own food. She often plays with the second daughter, Satoko. She also laughs loudly at the jokes of the fifth daughter, Shoko. Possesses the ability to generate shields. Limited to dome shapes. Can be applied to others simultaneously.

Riko. 18 years old. Waist-length wine-red hair with black highlights, styled in half-up twin tails. The fourth daughter of the six sisters, she is quite aggressive and often snaps at people. Although she isn't very upbeat, she reportedly shows a kind side only to the youngest, Ruriko. She is said to be a hardcore devotee of her youngest sister. She has even been improving her cooking skills for her sister's sake. She and the third daughter, Fukiko, are rivals regarding their height. They seem to get along rather poorly. Possesses the ability to turn into a dog at any time. Cannot maintain the form for long periods. The breed is a mix of Afghan Hound and Doberman.

Shoko. 16 years old. Orange hair with outward flips, tied in a ponytail with a large green ribbon. The refreshing, sports-loving fifth daughter of the six sisters. She is often seen playing outside. She is an early riser who naturally wakes up on her own. A mood maker who often cracks jokes to make people laugh, she loves comedy and sometimes speaks with a regional drawl. She is good with her hands and helps the youngest, Ruriko, with her studies. The youngest sister's clothes are tacky, but Shoko wants to protect her only little sister's smile, so she can't bring herself to say anything. She is terrible at cooking. Since she can basically eat anything and find it delicious, her seasoning is very haphazard. Furthermore, she has a dull sense of taste, so her sensibilities are slightly different from ordinary people. She calls her older sisters "[Name]-neechan." For example, she calls Nanako "Nanako-neechan." Can manifest objects she has created. Cannot be done unless she understands the structure to some extent. Example: Precision equipment like smartphones is impossible. She tries to understand the structure of musical instruments to some extent for the sake of the youngest sister Ruriko's ability.

Ruriko. 14 years old. Long yellow hair tied into two very thick braids. The shy, quiet, and rather dry youngest daughter of the six sisters. However, she shows a selfish side to her sisters. This is because the eldest, Nanako, and the fourth, Riko, spoiled her too much. She speaks politely to anyone other than her sisters, but sometimes says rude things unconsciously. She has a talent for music and possesses superior piano skills (though she seems to be able to play other instruments as well). Despite being able to play delicate melodies with those small hands, she is incredibly clumsy and reportedly very bad at drawing. She is also bad at cooking; she seems to make things quite seriously, but no matter how hard she tries, only failures appear before her. Her sense of private fashion is disastrous, but her sisters love her so much they can't bring themselves to tell her. She calls her older sisters "[Name]-neene." For example, she calls Nanako "Nanako-neene." Possesses the ability to semi-forcibly distract enemies by playing instruments. It feels like their consciousness is being drawn away, and it doesn't activate unless she plays an instrument. The effect is stronger the weaker the opponent is.
