Karasu is a unique and eternal being who repeatedly reincarnates every 100 years solely to eradicate Demons. Records of her date back as far as 1000 years.
Karasu gains power and advances in stages to become more powerful. To do so, she needs to consume Black Orbs from Demons.
While on a school trip, Shiori and her friends found her being chased by demons and saved her. At first glance, she speaks like a child, but she says things that no child would. Lacking almost any ability to defend herself, she relies on her guardian Kagura Mikazuchi for protection.
She is a calm, respectable young girl who is wise beyond her years.
Personality when she's Black Death (黒死病)
- "I'm not going to die. I will not. Not while I bear the mark of the ninja way!"
- ― Karasu
At the surface of her appearance, Karasu has a rather cool demeanor to her upon interaction. She can be calm until a present situation calls for her to get serious. She's not one for conversation as she believes that actions speak louder than words.
When fighting, she becomes very intense and focuses mainly on testing her opponent's strength to see them worthy of even fighting. This is especially displayed towards her heated rivalry with Shiori. When fighting a well versed enemy, Karasu can become ruthless and is not afraid to kill another if presented the chance/reason.
Karasu has shown to have trust issues due to her history of being a shinobi. She does not like being deceived but accepts the fact that it can be used as a tool in the shinobi world. Her own relationship with her comrades was not always strong, seeing as how none of them trusted her or even liked each other for that matter. However, leading to the incident that forced Karasu into exile, her relationship grew stronger with her comrades as they chose to follow instead of abandoning her. Now Karasu has a strong urge and responsibility to become a strong enough leader so that she can not only lead her team but protect them as they grow to become fearsome shinobi.
In her first stage, she takes the form of a young child. She has short black hair with red ribbons in her hair, she wears a long white and yellow elementary school uniform with a blue skirt that have white feather motif on them. Her expression is usually happy and she has odd emblems where her pupils should be. She's always barefoot.
In her second form, she takes on the appearance of a teenager, with a white dress with black trimmings and white shoes. Her hair is also longer and darker. Her face and expressions are usually serene and with a mysterious air to her. Her right eye is now red tinted while her left eye appears as a gold, inorganic clock face. The clock's position represent her "time", and is covered by bangs which are only revealed when transformed into a Spirit.
In her third form, she takes on the appearance of an adult, with a black dress with brown trimmings and black shoes. Her hair is now so long that it reaches all the way down her back. Her face and expression are usually ruthless.
As Black Death, her appearance is largely similar to her adult form, though her eyes now glow golden. She wears a black breastplate and red cape, both bearing the symbol present in her eyes.
