The March 28, 2013 issue of Famitsu Weekly has included an article on Kingdom Hearts χ[chi] (pronounced "Kingdom Hearts Key"), the currently Japan-only Kingdom Hearts game for web browsers. The article explains that while playing Kingdom Hearts χ[chi], the player will join one of 5 teams and compete against each other. The teams are based on animals, and are known as "Unikorunisu" (Unicorns), "Reoparudosu" (Leopards), "Anguisu" (???), "Urupeusu" (???) and "Urususu" (???). A full translation will be available soon.
