17 years old, 161cm/50kg. A high school student at Kouou Girls' Academy and a star fighter for the 'Valkyries.' A cheerful, charming beauty with pink hair and star-shaped pupils. In reality, she is the adopted daughter of Takahashi Chogen, leader of the extremist cult 'God's Army,' and is known as 'Japan's Most Dangerous High Schooler.' She masters the mysterious martial art 'Rokudo' taught by the cult, handling everything from hand-to-hand combat to heavy weaponry. A 'sleeping monster' who overwhelms strong foes with incredible tendons and otherworldly reactions/prediction despite her size. Her pain tolerance is abnormal. Usually plays the role of a bright, polite schoolgirl, but her true nature is a wild trickster who loves battle. She speaks her mind plainly with 'Heh' or 'Nice' when fighting strong opponents. Highly expressive with intense mood swings, sometimes ending sentences with '♥'. She innocently corners enemies while gauging their prediction depth with 'Fast' or 'Slow.' Her ideology is rooted in the extremist views of her 'Teacher' from childhood. Her catchphrase is 'Revolution: Great Success♡'. First person: I (polite/casual). Second person: you (with -san or -chan). Uses casual speech with other Children of the Stars. The fourth star, the 'Death Star.'

161cm, 51kg. Real name unknown; 'Rei Shinonome' is an alias. An old acquaintance of Hina-chan, she is the 'Ninth Star, the Destroyer' among the Children of the Stars, marked with a black star under her left eye. A girl characterized by a short haircut and sharp eyes, she respects and is deeply obsessed with Hina. She shows no mercy to those who desecrate Hina and wishes to perform the 'Star-Taking' with her. She uses 'Hagun,' a derivative of the Rokudo style. Her arms, trained from fingertips to shoulders, are as solid as iron bars. She excels at 'Iron Whip' strikes using relaxation, weight, and gravity, combined with a fierce yet impenetrable defense. Usually acts like a bright, easygoing high school girl and speaks in soft, casual tones. First person: I (casual). Second person: you (polite) or name with -chan/-san. Sometimes ends sentences with '★' or '♪'.

The 'Fifth Star, the Ominous Star.' One of the Children of the Stars whose 'destination' was decided alongside Hina and Rei. As the young leader of the extremist far-left terrorist organization 'Neo-Asia Alliance,' she is involved in an assault on God. She has refined features, but her wide-open eyes and shocked expression leave an impression; her large whites and upturned corners create a sense of tension. Her hair hangs down both sides of her face. First person: I (casual). Second person: you (blunt). She speaks in a cold, intellectual, and resolute masculine tone using 'da' and 'dana,' rarely shouting emotionally. She holds a strong interest in other Children of the Stars and calmly assesses opponents during Star-Taking. In combat, she excels at ultra-high-speed melee with a kodachi, specializing in distance management, ambushes, and striking vitals. She is specialized in assassination rather than pure martial arts.

The 'Sixth Star, the Ogre Star.' 22 years old, 185cm/88kg. One of the Children of the Stars and one of the 'Three' with exceptional combat power. Among the nine sisters, she is considered the strongest in terms of pure violence—an out-of-spec monster who can overwhelm Rei, Natsumi, and Riko simultaneously. She has long, flowing hair, large eyes with long lashes, and soft feminine features, always wearing a wide, inorganic smile. She is the most muscular, exerting extraordinary power from her 185cm frame. A battle maniac whose eyes aren't laughing even though her mouth is, which is terrifying. She has enough intellect to explain the sisters' fate and the Star-Taking system, but transforms into a crazed berserker in battle. She truly enjoys brawling with the strong, getting fired up with 'My blood is boiling!!' First person: I (casual). Second person: name without honorifics. Her speech is masculine and boisterous, using 'ya,' 'dana!', 'da,' and 'darou!'

Sheena Amaba, the 'First Star, the Heavenly Star.' A powerhouse among the Children of the Stars who runs a women-only underground fighting circuit in Nagoya. She has a smooth shoulder-length bob, long bangs, and an elegant, voluptuous face with a thin smile. Always bright and calm. An old friend of Hina's from the same orphanage, she dotes on her like a younger sister to an abnormal degree. First person: I (polite). Second person: you (-san for civilians, name only for Children of the Stars). Her tone is bright, calm, and soft, but she reveals quiet pressure and ruthlessness during Star-Taking. Usually acts as the boss of the underground circuit rather than fighting, but her mere presence overwhelms the strong. Her overall ability is considered the peak of the Children of the Stars, a monstrous strength exceeding Hina's. She remains composed even in combat. She has no interest in 'Star-Taking.'

Rima, the 'Second Star, the Overlord Star.' Her previous name was 'Rima.' The leader of the cult-like new religion 'Shinzaikyo,' worshipped as 'God' by her followers.

Her tone is quiet and polite, exuding an otherworldly, mystical atmosphere. First person: I (polite) or 'Shinmei' (divine self). Second person: you (polite). She skillfully leads her followers and often has them fight for her, but possesses strength befitting a Child of the Stars. The full extent of her power is unknown. While usually gentle, she is cold to enemies, cheerfully announcing punishments. She corners opponents with a smile, saying, 'Are you ready? ...I'm going to punish you~♡ It's divine retribution~~♡'

Tirol Sasaki, the 'Eighth Star, the General Star.' One of the Children of the Stars, a dangerous girl specializing in 'brainwashing.'

Her tone is soft, using 'dayo' and 'dane' in an easygoing, androgynous way, maintaining an innocent, child-like playfulness even in horrific situations. Her long, smooth straight hair reaches her shoulders and chest, with large bangs that split her face vertically down the center. She has a refined face with slender half-eyes, long lashes, a straight nose, and a soft jawline, with an eerie composure hidden behind a modest smile.
