An unknown ability from Kafka is bloodlust...though Kafka isn't some sort of vampire...and this ability only shows itself in situation where she is in the verge of deteriorating...her fangs will slightly extend to be longer and sharper...all she needed to do is to drink someone's blood and she will get that superhuman boost

Kafka is part of a faction called Stellaron Hunters...

The Stellaron Hunters are a faction in Honkai: Star Rail. Founded and led by Elio, they are a mysterious organization that collect Stellarons. They are said to work against the Interastral Peace Corporation.

In a quiet moment in time, the Stellaron or Cancer of All Worlds began to cause ripples across the stars, like a rock tossed into a pool of water, and began to expand its influence. Before anyone noticed, this twisted and unknown matter had already corrupted a great number of worlds, and the fancy colorful gem known as the Stellaron was in its company.

Death and despair followed wherever the Stellaron went. For many civilizations who have experienced the disasters it brings, the Stellaron was a symbol of destruction. However, even knowing its destructive nature, the fearless few travel between the worlds to obtain the Stellaron. They call themselves the Stellaron Hunters.

No one knows anything about the Stellaron Hunters aside from what they have done. Which Aeon do they worship? What do they want with the Stellaron? With the galaxy filled with rumors about them, only one thing is for certain: Though the Stellaron Hunters are few in numbers, each of them holds incredible capacities and powers. The Stellaron Hunters are considered criminals as they show to take Stellaron in their universe...hence the name "Stellaron Hunters" and for this...Kafka has a bounty of 10,890,000,000 Credits in the universe...

Kafka has the ability or combat style to use lightning. In her missions, she is seen holding dual submachine guns. Kafka also has the ability to summon pink lines where she has full control over it, as for example, she can use this ability to tie someone up and hold them captive or it could be used as a basic slash attack like a puppeteer would with the strings of a doll. Kafka also has an ability called "Spirit Whisper" which allows her to hypnotically manipulate people through language, Kafka used this in one of her battles which she spoke "Listen" or "Listen to me" to start manipulating the victim.
