A mainline Atelier game that's completely offline, standalone, and without gacha elements. This mainline entry sticks to the longtime traditional Atelier series gameplay experience while also building upon it. Atelier fans can enjoy an evolution of the familiar Synthesis and Turn-based Battle systems, culminating in a heartwarming story for all to enjoy. A separate original title set in the same world of the "Atelier Resleriana" gacha game awaits from developers Gust & Team Ninja.

Two young adults return to their lost hometown in search of truth and to bring back what they hold dear.

The town of Hallfein was once situated at the border of three provinces, and thrived thanks to mining and trade. However, a mysterious disaster struck this peaceful town, causing most of its residents to disappear. The town became a restricted area, and only investigators dispatched from the capital were allowed to enter.

As time passed, restrictions on the town were lifted, and a plan to restore it was initiated. Seizing this opportunity, a young woman and a young man, having come of age after being driven from Hallfein long ago, now return to the land they once called home.

The former hopes to restore the shop left behind by her missing grandfather, and the latter seeks to investigate the mementos left to him by his father. While their reasons for returning differ, they share one common goal: uncovering the cause of the townspeople's mysterious disappearance.

After meeting in their hometown, the two embark on a journey together to seek the truth, unaware of the encounters and revelations that await them...
