K'Sante's launch was complicated by some of Riot's marketing efforts. Lil Nas X is this year's "League of Legends" World Championship performer, after the annual esports event "hosted" a group of virtual Korean pop stars called K/DA (a group invented by Riot) in years prior. Lil Nas X's collaboration came with a big marketing rollout: The singer debuted a new theme song, and starred in several advertisements where he pretended to be the so-called president of Riot Games. The collaboration will also help Riot sell in-game merchandise: Lil Nas X designed a cosmetic skin for K'Sante that will be sold for real money via in-game currency.
