PROMETHEUS is a Previous Era super AI created by Dr. MEI to predict and manage Honkai attacks, as well as assist in her research. PROMETHEUS was divided into 17 fragments all bearing the same name, given to them by Mobius, who said that she wanted them to have a human name. The fragment relevant to the story is Number 17, who insists she should be called No. 17 and not PROMETHEUS even when Mobius is about to die. It predicted that there would be a total of 14 Herrschers that would appear. The 14th would be far stronger than all the Herrschers before it. It made sure that the Herrschers who would appear in the Current Era would be the exact same as the Previous Era, thus helping humanity's preparations against them. In Mobius' words, PROMETHEUS is "the biggest contributor to the war against Honkai in the next era-because the Herrschers they will encounter, starting from the Herrscher of Reason, will be the same as those in our era." An artificial intelligence created by Dr. MEI to be an assistant who functions based on pure rationality. Created without an emotion module, PROMETHEUS operates on logic, calculations and probability as the basis of her way of thought in order to provide the most rational solutions for her companions, and demonstrates great difficulty in understanding human emotions and decisions made against rationality, sometimes to the point of becoming outright unresponsive. Despite this, PROMETHEUS makes attempts to better understand the nature of humanity and human thought. On rare occasions, PROMETHEUS has herself demonstrated and acted on what can only be described as human emotion, such as when she struck Kevin Kaslana in anger, which suggests that her intelligence isn't as rigid as she might think.

She holds Seele in high regard, viewing her as everything that she's not; gentle and caring, someone that everybody likes. This in turn makes her view herself negatively and if Seele's friends find out who she is, they will dislike her thus making her even more withdrawn from Seele's social circle. Since she only knows how to solve problems through fights, she's clumsy and socially awkward especially when dealing with Seele's friends, particularly Bronya Zaychik and Kiana Kaslana.

Raven (originally named Natasha Cioara) was born in Siberia. Following the Second Honkai War, in which she gained strong Honkai resistance, she was selected by the Gray Serpent and was forced to leave her brother behind. Natasha received training and became a mercenary subject to the World Serpent. In 2000, when the core of the Herrscher of the Void was out of control, a huge amount of Honkai energy overwhelmed the entirety of Siberia and caused its people to become corrupted. Thanks to the sacrifice of Cecilia Schariac, most people, including Cioara and her brother, had survived under the protection of the Holy Blood of Schariac. However, Cioara gained resistance to Honkai and was taken away by the Gray Serpent, and was trained as a combatant of World Serpent. Her appearance underwent many changes during that time and she'd be given the codename "Raven". As a mercenary, Natasha is a practical individual with a no-nonsense attitude, who believes in a strict work ethic in which a job is a job and must be accomplished to its fullest in spite of any personal reservations or dangers to herself. Befitting of a mercenary, Natasha holds no true loyalty to any cause or faction besides whoever's paying top dollar—which most often happens to be the very organization that raised her. Natasha also holds a great sense of respect for the Sire of World Serpent. Natasha has been shown to have a penchant for dry humor, fine alcohol, and the occasional philosophizing. But perhaps the most surprising part of this ruthless mercenary is her caring nature, possessing a soft spot for children displaced by the Honkai with nowhere to go, much like herself when she was taken in by World Serpent. Natasha takes in many such children under her care and tutelage, and although she sees to it that they are taught how to survive on their own, above all else she tries to make sure that they are able to live their lives as comfortably as possible with a place to call home.

She cut ties with the company that managed her and secured a performance on her own. The first venue she got a spot on was a small one for charity. Some of the people who attended recorded her singing and posted it online, which garnered a lot of attention. Professionals praised her talent, and said she would rise to popularity at some point. There were also critics, of course. Despite the challenges on her path, Eden did rise to the highest stage. Her generosity and talent brought in more and more fans until she was the biggest name of her time. She lived in extravagant homes, and drank the finest wine, all while improving with each performance. But Honkai ended that life.

The man who was the "Weakling" commanding her old comrade's "third-rate squad" is now a "Junior Blockhead" whom she can (occasionally) rely on. Though she maintains the "tough" in "tough love."
