Events appear for special occasions, such as holidays, and contain special missions that unlock unique characters (classified as "Special"). Completion of an event mission will reward the player with a random amount of cards for the Special character as well as cards for one random common character. Players must then wait 4 hours for a new mission to appear in order to unlock more cards for the unique character, or use Red Star Rings to unlock another mission immediately (the cost of this increases every time the player unlocks another mission unless those four hours are allowed to pass). Players have about one week to unlock each special character before the event ends and they become unobtainable.
