KafBlade

KafBlade is the het ship between Kafka and Blade from the Honkai: Star Rail fandom.

Canon
Kafka and Blade are both members of the Stellaron Hunters, a mysterious organization that works under Elio's orders and collects Stellarons. Not much is known about their history yet or how they met. The "Passerby's Ragged Embroidered Coat" relic hints that Kafka was the one who recruited him into the Stellaron Hunters. The relic describes a woman in sunglasses (Kafka), as well as a man in armor that stood in Blade's way to extend him an invitation. Blade refused their offer, resulting in a fight, but the "smiling woman" offered him a deal he could not refuse, and so he accepted.

At one point in the story, Kafka contacts the Astral Express crew after Blade gets captured by the Cloud Knights of Xianzhou. She wants to bring back "her companion" and asks the crew to rescue him as he is apparently innocent.

Later, when Kafka escapes and is pursued by the Trailblazer, Blade jumps in and threatens the Trailblazer with his sword. Kafka has no reaction to this, suggesting she knew of or expected his arrival. She tells him to come along as they have two more places to visit before letting herself fall of the roof. Following this, Blade jumps after her.

Fanon
Kafblade is a decently popular ship for both characters.

In regards to their relationship, it is often interpreted that Kafka takes on the more dominant and playful role in the relationship, as well as Blade being incredibly loyal to Kafka and obedient to her orders. A trope often found is Kafka being able to make the usually cold Blade flustered.

Kafblade are commonly both viewed as bisexual by fans of the ship. As some other fans headcanon them as other sexualities (lesbian/gay), there has been discourse surrounding the ship.

Trivia

 * Kafka refers to Blade as "Bladie."
 * In Chinese, she calls him "阿刃 ārèn", with 阿 being a prefix for names to indicate closeness.
 * Blade can be seen holding an umbrella for Kafka on her splash art.
 * Blade and Kafka can be seen texting in the light cone "Before the Tutorial Mission Starts." The story suggests Blade is irritated by having to take care of Silver Wolf and asks Kafka when the action starts. Kafka thinks he has nerve asking that, telling him that Silver Wolf must pass this assignment. When Blade tells Kafka she's doing well, Kafka is relieved and tells Blade that he is also a reliable operative, to which Blade responds "..."
 * Since Kafka is missing her sunglasses in the illustration, some suggest that Blade could be wearing hers.
