Koei Tecmo Europe and developer Gust announced that their new Atelier game, Atelier Resleriana: The Red Alchemist & the White Guardian, will be released on 26th September 2025 on PlayStation®5, Nintendo Switch™ and Windows PC via Steam®. In celebration, a first look video with commentary from the developers was released. Players can meet the new and familiar characters of this new magical adventure, and get a first glimpse of the game system and the world they will explore.
Atelier Resleriana: The Red Alchemist & the White Guardian takes players on a new mysterious and cosy adventure alongside new characters Rias Eidreise, an adventurer with a talent for alchemy, and Slade Clauslyter, a young man capable of opening entrances to dimensional paths leading to alternate dimensions. These two protagonists will join forces in an attempt to discover the reason for the disappearance of the inhabitants of Hallfein, while also trying to follow in the footsteps of their loved ones and restore their hometown. During their journey, they will meet various characters who will help them, including familiar faces from the Atelier series such as Sophie Nuenmuller, Razeluxe Meitzen, Totori Helmold and Wilbell Voll-Ersleid.
Watch a new first look at the game in the player below:
Set in the universe of Atelier Resleriana: Forgotten Alchemy and the Polar Night Liberator,this new Atelier title will transport players to the continent of Lantarna, where they can explore, gather ingredients for synthesis and discover every secret corner, day or night, rain or shine. Players will also have the opportunity to explore multi-level dungeons, known as “Dimensional Paths”, where the structure will change randomly with each visit, allowing players to gather different ingredients and challenge new enemies depending on the difficulty level chosen.
Fights in Atelier Resleriana: The Red Alchemist & the White Guardian will blend strategy with turn-based combat for strategic timeline command battles where players can form a team of six characters (three in the front line and three in the back). By using action points and equipped items to their advantage, users will be able to inflict damage and influence the timeline of characters’ turns, triggering consecutive turns for allies and activating powerful unite attacks.
Using ingredients gathered during exploration or combat, Rias will be able to synthesise various items during a process called “Gift Colour Synthesis”. During this synthesis process, players will have to connect the “Gift Colours” of the ingredients together to create new items. They will also be able to assign traits or change recipes depending on the ingredients used. When certain characters come to lend Rias a hand, this will further strengthen the item created.
In addition to the traditional Atelier gameplay system alternating between exploration, combat and synthesis, users will be able to sell items via Rias’ shop while helping to develop the town. By selling synthesised items, players will earn money they can invest in the development of Hallfein, thus unlocking new recipes and progressing through the main story.
Atelier Resleriana: The Red Alchemist & the White Guardian is currently in development and is scheduled for release on 26th September 2025 on PlayStation®5, Nintendo Switch™ and Windows PC via Steam®. The game will be available as an entirely offline adventure with no internet connection required*. The PlayStation® 4 version will not be sold outside of Japan.
Everyone who purchases either a physical or digital edition up to the first two weeks after release will receive the “Activewear Adventuring Set” for Rias and Slade, and the “Adventuring Charm Set” as early purchase bonus.
Atelier Resleriana: The Red Alchemist & the White Guardian will include Japanese voices with English texts only.
