Claimed by the Void when she was only a child, managed to survive through sheer tenacity and strength of will. Her experiences have made her a deadly hunter and, to some, the harbinger of a future they would rather not live to see.

Background[]
Early life[]
Kaisa was an ordinary girl born in the southern deserts of Shurima. During her tenth summer, she came upon a pen of sacrificial goats. The girl tried to release the animals but then, suddenly, the ground shook, flashes of light scorched the sky, and a rift opened up the earth. The rift swallowed up the entire village and everyone inside.
Now trapped under the desert, Kaisa could hear the faint voices of others trapped inside. But soon, hers was the only voice left. The first void creature she encountered was about her size. After being knocked down by the voidling, Kaisa drove her knife into its heart, killing it.
Although the creature was dead, its flesh clung to Kaisa’s arm. She was unable to remove it and soon enough, it started growing around her as though it was becoming part of her. She was able to use the second skin as armor against other void creatures. The longer she survived against the void, the greater her confidence grew until she finally managed to escape back to the desert surface. No longer was she the little girl who fell into the rift but was now a fearless hunter of the void.

Trivia[]
- She is around 20 years old.
- She was 10 when she fell into the Void tunnel and has stayed there for about 10 years.
- Kai'Sa is 169.6 cm (5’6”) in height like her .[4]
- Kaisa is her given name, Kai'Sa is her adopted Void name.
- Her symbiote can sustain her through the Void-spawns they kill by absorbing their essence, but that isn't really pleasing to her. After the earthquake she unwittingly caused, she scavenged leftover food from castaway sources in the catacombs— water skins, rotting fruit, etc. Now that she can get out from the underground, she likes eating what she can find around
Shurima, preferably peaches. But the suit has to feed too, and she is somewhat fearful of what it might do if she doesn't continue to hunt and sustain it.
- Due to her symbiote, Kai'Sa is stronger than normal humans while gaining abilities like blasting , especially when wearing her helmet-like empowered senses (like a special vision that is either thermoreception or X-ray vision).
- Despite common belief, Kaisa was never trapped in the Void itself, rather willingly stayed within a complex underground tunnel system between the massive Void rift that caused the earthquake of her lore and the surface of the Sai desert, sculpted through years by the spawns that breach from the rift.
- The lines that decorate her face are tribal marks made out of Voidborn blood.
- Unlike other beings exposed to the Void's influence, Kaisa was able to avoid its seething madness thanks to her suit's helmet, which allows her to safely remain within the vicinity of Void rifts.
- It has been theorized that the creature whose part would later become her second skin belonged to the same species as
- One of her quotes to him is "I know your tricks".
- Both the symbiote and Kha'zix evolve to become stronger.
- Both have the potential to become invisible and shoot more projectiles after certain evolutions.
