Hourglasses (shortened as HG) are considered the in-game currency of Mystic Messenger that the player can acquire either for free in-game or through in-game purchasing. While they are not necessary to progress, as you can go through the Casual Story perfectly fine without them, they can be very helpful. However, they are necessary to unlock the Deep Story, Another Story, After Endings of the characters, and more extra content.
Prices for hourglasses will vary from country to country depending on the country's exchange rate with South Korea.
