Kai’Sa is a fairly new champion, who plays as a marksman. In League of Legends lore, she spent most of her life trapped in The Void, a horrific dimension filled with disgusting monsters. She came back a killer, who zooms around, shooting missiles from the cannons that float above her shoulders. She’s represented by Jaira Burns, another American singer who released her debut EP, Burn Slow, earlier this year.
