1,000 years ago, an Evil Mage attempted to take over the world, but was stopped by the Legendary Warrior.

One day, gigantic red crystals crash from sky, changing the regional seasons into their opposite and sending the world into turmoil.

Ary decides to set out and take her brother's place, as her father is still grieving Flynn's disappearance.

Soon after arriving, Crocus knocks out Ary and reveals he stole the guardian's seasons crystals.

The Evil Mage escapes and reveals to Ary that her brother Flynn is still alive but not in the current time period.

In 2017, the production of Ary and the Secret of Seasons started and was first shown at Gamescom, winning the Best Unity Game award 2017.
