Fami (Au 2)

Powers of the Devil:
Life Absorption: The Devil of Hunger has the ability to absorb the life of those with whom it comes into physical contact, draining them and reducing them to desiccated corpses. While the full extent of this ability is currently unknown, it can be used on demons, humans, and animals.
Immense Healing Factor: The Hunger Devil can use absorbed energy to heal herself from even mortal wounds, as shown when she drained the energy of one of the Festival Committee students to revive herself after a confrontation with the Fake Chainsaw Man. It seems that the life energy she absorbs doesn't need to be proportional to the damage received to heal, as seen when, after absorbing the life energy of some ants, she managed to recover from fatal injuries.
Immense durability: Unlike many other demons, the Demon of Hunger is capable of surviving fatal injuries, such as having its body cut to pieces, and can even speak while its head is separated from its body.

Fami demonstrates great confidence in her combat abilities and, contrary to her usual personality, appears relatively calm and serene when facing a formidable opponent. She utilizes basic hand-to-hand combat techniques in her attempts to fight the physically imposing Fake Chainsaw Man, analyzes his fighting style, and boldly claims to be able to defeat him in mere seconds, despite having been quickly dismembered by him moments before. From her genuine shock at being defeated, it can be inferred that she may have been a much more powerful fighter at some point earlier, but that she was drastically weakened to the state she was in at the time of her appearance. Furthermore, she seems able to assert herself against her sisters, rebuffing Yoru's taunts when she calls her weak.

From what we've seen so far, Fami appears to have a docile and taciturn demeanor, being very emotional, in stark contrast to her sisters. She became nervous when introducing herself to the students of the Fourth East High School, crying throughout the presentation and openly sobbing when she realized that no one was paying attention to her. At the same time, she seems to have a certain self-esteem, refusing to take out the trash because she considers it a waste of her superior talents. Despite this, when reprimanded by a student for her behavior and told to "go crush ants," she actually goes out to do it. When she is easily defeated by the Fake Chainsaw Man, she immediately begs for her life, offering him a meager 2,000 pounds from her wallet, demonstrating an evident cowardice that her sisters do not possess.
Fami seems to pity humanity and arrives claiming to save it with her special powers. Her notion of salvation appears to be that of freeing humans from the suffering caused by death, as she believes her methods will alleviate any pain that War or Death might cause. Although she doesn't display the same bravado as demons like Makima and Yoru, and could be considered benevolent, Fami is still deeply fatalistic, as seen in her way of "saving" humanity: to heal her wounds, she doesn't hesitate to help an innocent student and steals his life force. Despite this, her plea for Death to kill herself demonstrates that, in her own distorted view, she ends up siding with humanity against the demons.

Fami's current form resembles that of a humanoid woman with long, messy blonde hair that falls in layers and irregular strands. Some strands stand out, with bangs on her forehead and sides that reach her ears, and longer bangs that vaguely reach her collarbones. Like the rest of her sisters, the Demon of Hunger possesses green eyes with multiple rings and wears the standard uniform of the Fourth Eastern High School, similar to that of other Demon Knights who attend the school. In most of her appearances, she displays a nervous expression on her face and is usually shown crying; she is the age of the fear of hunger, probably being over 1000 years old or so.
