First person: I (majestic, archaic). Though she appears to be a cold-hearted queen at first glance, her actual personality is simple and gentle. Because she speaks with polite diction, there is no sense of overbearing pressure. Her relationship with the others is excellent, as she responds to Ain and the others' requests even when she doesn't fully understand their intent. Her most prominent feature is that she is a complete humanoid with a halo. She wears a massive hat resembling a military cap, has white skin and clothes like Ain and the others, and X-shaped marks appear in her eyes. Bit-like objects float around her. In the early logs, a version without the hat could be seen. Midway through the story, she finally revived after the collection of necessary resources was nearly complete. She enjoys heartwarming interactions with Ain and the others, but since she doesn't know what she should do as a Prophet, she adopts Soph's declaration of war as their future policy. Incidentally, the book she reads to Ain and the others is not an original, but a version uniquely interpreted by a certain school. Her abilities are quite high; when Alice and the others were camouflaged to avoid detection by Aur and the rest, she was the only one who noticed something was off. Furthermore, she holds firm convictions regarding the "free will of AI" that are enough to convince Aur and the others, showing her leadership as the "older sister" who guides the Decagrammaton faction at key moments. While specific figures are unknown, she is quite tall.

She wears a mechanical mask over her mouth, but she is not unable to speak; she talks with a somewhat timid tone. She has a faint-hearted way of speaking and often lets out a squeal like "H-hee..." While she is usually described as having a cold demeanor and being the most motivated when it's time to act, she seems to be the most moderate of the three, sometimes showing concern for Sensei and the others when talking among her comrades. She also seems to be physically delicate, frequently fainting from shock. Basically, she is honest, cowardly, and a pushover. Perhaps because of this, she is the one most influenced by Sensei and the others. By the way, her hobby is playing house, and she secretly enjoys playing house using the Labors. She has a hobby of building (unnecessarily) giant and complex machines. She seems to prefer analog machinery that doesn't rely on electronic devices. Apparently, she is the most knowledgeable about machinery among the three and is considered the hardware specialist.

She wears earmuffs, but she isn't deaf; she is capable of proper conversation. Also, she seems to have an interest in humans and has a hobby of personally researching their technology and culture, to the point of being well-versed in dirty slang, which leaves Aur exasperated. Among the three, she has the most bellicose personality and speech. It has become a standard routine for her to deliver physical punishment when teased by Aur, or to tease Ain herself. Emotionally, she seems to be the most developed of the three, and she was the one most pained by Tiphareth's sacrifice. She is said to be the software specialist among the three.

Although her eyes are covered by a ribbon-like band, it doesn't mean she has no vision; in the spot where a human's left eye would be, she has three small yellow eyes lined up vertically, which change color along with her expressions. Also, in some scenes, tears flow from under the band, so it seems she does have both eyes. She appears to be the leader figure who keeps the three together, holding the position of supervisor alongside Ain (Hardware) and Soph (Software). She is also well-versed in electronic warfare, having dealt with Rio's hacking attempts and performing information camouflage for her allies. Furthermore, she is knowledgeable about weapon information that hasn't been disclosed outside of Millennium. She speaks politely but also shows a cold-heartedness in how she views others. She seems to have a slightly sadistic streak, becoming very lively when teasing Ain or Soph. However, she often goes too far and makes Soph snap, resulting in physical punishment as a daily occurrence. She also shows a childish side appropriate for her appearance, such as throwing a tantrum when she loses in electronic warfare.
