Is Kai’Sa Related to Kassadin?

In the world of League of Legends, a champion’s personality and their connections with other champions in the same universe define their character.

Although there is no official confirmation, many fans believe that Kai’Sa is the daughter of Kassadin. Voice lines and references in the lore strongly suggest this relationship. Today, we will explore the connection between Kai’Sa and Kassadin.

Kai’Sa, Daughter of The Void:

Fans speculate that Kai’Sa is Kassadin’s daughter based on their titles and aliases. Kassadin is known as “The Void Walker” while Kai’Sa is called “Daughter of The Void”. This implies that Kai’Sa is the daughter of the only other person to have survived The Void, Kassadin.

Both characters belong to the same region, “The Void”, like other champions in the League universe who have connections to each other.

Background of Kai’Sa and Kassadin:

Kassadin and Kai’Sa come from the same village. When Kai’Sa was a child, an earthquake caused by sacrificial goats released into a Void-linked canyon led to the village being swallowed by The Void. This event motivated Kassadin’s quest for revenge against The Void after losing his wife and child. He and Kai’Sa are the only humans to have survived The Void from their village.

Kai’Sa spent 10 years in The Void, combining with a Void Symbiote to survive. Her suit granted her powers, and her determination helped her adapt to the predatory nature of the Voidborns. She had to become a skilled hunter to confront the dangers she faced. Her hardships in The Void shaped her into the person she is now.

Kai’Sa’s Relation To Kassadin Hinted In The Voice Lines:

In League of Legends, voice lines between characters hint at their relationships. These voice lines strongly suggest that Kassadin is Kai’Sa’s father. Some of the voice lines include:

  • “Huh, memories of my father come at the strangest moments.”
  • “Reunions can be so bittersweet.”
  • “Could it.. be true?”
  • “It smells like home here.”
  • “Father?”

These lines indicate that Kai’Sa feels a connection to Kassadin and that he reminds her of her father. The line “Could it.. be true?” refers to a conversation between Kai’Sa and Bel’Veth, which we will discuss in the next section.

Bel’Veth’s Discourse With Kai’Sa:

In the short story “Pinwheel” by Jared Rosen, Bel’Veth reveals that Kai’Sa and her father are the only humans to have survived The Void. This revelation leaves Kai’Sa shocked, as she had believed her father was dead. Bel’Veth’s voice lines further support this relationship. After killing Kassadin, she says, “As stubborn and brave as your daughter, and now so am I.” This refers to the threat Kai’Sa made to Bel’Veth earlier in the story. The full story can be read here.

Kassadin in The Music Skin Line Universe:

In the K/DA Comic released on September 27, 2020, Kai’Sa’s journey of discovering dancing and joining the K/DA group is portrayed. The comic also briefly mentions Kai’Sa’s father, who takes her to different places. Michael Yichao confirmed on Twitter that this human father figure is “Kassadad.” This implies that in the K/DA Music Universe, Kassadin is Kai’Sa’s father. The tweet and the comic can be seen here.


Although Riot Games has not officially confirmed the Father/Daughter relationship between Kassadin and Kai’Sa, the voice lines, lore, and K/DA comic strongly suggest this connection. It is ultimately up to the reader to form their own conclusion, as the League of Legends universe continues to expand. What are your thoughts on this matter? Do you believe there is enough evidence to establish this relationship, or do you think official confirmation is still needed?
