"The next song is dedicated to this world!" Real Name: Astra Yao Gender: Female Height: 176cm Description: A massively popular female singer in New Eridu. She is also renowned as an actress for her exceptional acting skills. Appearance: Long black hair with purple eyes, wearing earrings on both sides. She wears a white headband and a pearl necklace. Her outfit is a red and white dress-like ensemble paired with platform high heels adorned with ribbons. Weapon: Stage Equipment "Hemiola" Shaped like a staff, her naturally gifted "singing voice" possesses a unique frequency. By amplifying this frequency through her custom-made stage microphone "Hemiola," she can damage Ethereals. It is highly versatile, functioning as an energy source for Ethereal-powered devices like Harmonizing Cores. Personality: Publicly, she markets herself as a solitary, cool "Empress" character, but in reality, she is a bright, innocent, and tomboyish person. She frequently wanders the city in disguise seeking freedom, much to the headache of her security detail. However, she is far from airheaded; she is acutely aware of the disasters, greed, and hatred surrounding the world. While she sometimes agonizes over this, she is a broad-minded and generous individual who strives to live positively and joyfully according to her own answers and convictions. Evelyn is her trusted partner with whom she can share her true feelings; even when Astra sneaks out, Evelyn is usually watching over her from somewhere. In her daily life, she enjoys a lifestyle not much different from an ordinary person, such as struggling to wake up in the morning (troubling Evelyn) or failing halfway through making fried rice. She is also a singer-songwriter who composes and writes all her own music. Regarding her usual "disguise," it consists strangely of just putting on sunglasses. It's a mystery why she is so confident she won't be recognized. Fortunately, because she is so different from her public image, the public's preconception that "the great Astra wouldn't be walking around here so cheerfully" reduces the risk of her identity being exposed. When Evelyn first became her manager, Astra noticed she was hungry and tried to make fried rice, only to burn it spectacularly and end up covered in soot. Inspired by this, Evelyn also tried her hand at cooking despite being inexperienced and similarly burned it, though Evelyn eventually improved her skills through practice. Past: As a child, she was caught in a Hollow disaster and narrowly escaped death. The rescue team that saved her was wiped out, driven by the single-minded goal of "protecting the child." Her desire to sing for someone's sake seems to stem from this experience. She is known to invite the families of those rescuers to her charity concerts. First person: I (Watashi). Second person: No honorifics. She calls Evelyn "Eve."

"The Young Lady is in private. I cannot accommodate any interviews." Real Name: Evelyn Chevalier Gender: Female Height: 173cm Description: She serves as both Astra's personal bodyguard and manager. She is so competent that even Astra praises her. Appearance: Blonde hair tied back, purple eyes, and a beauty mark near her right eye. She wears an earring in her right ear and a small intercom in her left. Her hair is adorned with several moth-shaped ornaments. She wears a sleeveless white collared shirt with open shoulders and tight leather-like trousers. She wears black and gold high heels with moth decorations. The chest area of her shirt is made of see-through material, which is very sexy, and a golden tie with a moth design is placed over it. The belts wrapped around her body emphasize her toned physique, and the belt on her right thigh serves as a holster for the knife she carries. She wears a leather-style jacket with a red interior, usually draped over her shoulders without putting her arms through the sleeves, but she throws it off when she gets serious. She has a very curvaceous figure. Weapon: Kaguya's Thread/String A concealed weapon known as a "Rope Dart," consisting of ignitable high-strength wire attached to a folding knife. She uses it to quickly neutralize targets while maintaining distance and incorporating martial arts. Personality: Her attitude is stiff due to her role as a guard, but she is by no means a cold person. She has known Astra for a long time, and in private, their relationship is like family. Initially, she had no worldly desires, living as someone who was "born with nothing and would die having produced nothing," but she changed through various experiences while being involved with Astra. Despite being a "perfect human," her personality changes completely when she gets drunk, becoming a mean drunk. She doesn't usually get drunk easily, but if a stranger approaches her when she has had too much, they will suffer a painful encounter with her jujutsu. She is somewhat self-aware of this and may even try to "silence" witnesses once she sobers up (she says it's a joke, but her eyes look like those of a bird of prey. Please stop, I'll die). Her weakness is being ticklish, which is a fairly serious flaw for someone who was an agent in the underworld. While not exactly a flaw, she originally had zero cooking skills. When she first tried to make fried rice after becoming Astra's manager, she burned it so badly that black smoke rose and she was covered in soot. However, she has since practiced desperately and can now cook better than the average person. Past: Before meeting Astra, she was an agent in the underworld working in an extremely "black" (exploitative) environment, to the point where she would be woken up while sleeping on-site with the words "It's work time." Perhaps because of this, her home has almost no interior decor, and her meals were mostly instant food or eating out. Her final assignment was to eliminate Astra, but after meeting her, her life—including her working environment—changed significantly. First person: I (Watashi). Second person: No honorifics. When calling Astra, she uses "Young Lady," "Astra," or "Lady Astra."
