The graphics and volume have increased since the release.
We decided to raise the price after the sale, considering the price that matches content of the game.
The price will increase after Winter Sale ends, so now is your chance to buy!
We will update the content in line with the price increase in the future.
・Apology and correction
We previously announced that the price will increase after the autumn sale ends,
