Events

Events are time-limited special occasions that may involve certain mechanic of the game, or interactions outside the game. They give various rewards such as Costumes. There can be 0 or more active events at a time.

Note that events' end times depend on the player's timezone, and the ones listed here are based on Seoul's timezone (UTC+09:00).

There are two types of events:
 * In-game: Events that require the player to do various things in the game.
 * Off-game: Events that require the player to do various things outside the game.
