Atelier Resleriana Switch, PS5, and PC Game Release Date Set

Koei Tecmo and Gust confirmed we’ll see Atelier Resleriana: The Red Alchemist and the White Guardian this fall on the Switch, PS5, and PC, as it set a release date. The official site confirmed it will debut on September 26, 2025. Pre-orders are open, and there’s a digital early purchase bonus for getting it by October 9, 2025. There are also two new trailers looking at the game.

Everyone in Hallfein disappeared, and nobody really knew what happened. However, Rias Eidreise and Slade Clauslyter are going to find out. The two grew up there and return at the same time once people are allowed to return to the area. Rias is the alchemist this time around, while Slade can use a Geist Core that lets them go to alternate dimensions to aid in their investigations.

Here’s the trailer that highlights the Atelier Resleriana: The Red Alchemist and the White Guardian story, shows off gameplay, and shared its release date for the Switch, PS5, and PC versions appearing worldwide.

There is also a version of this trailer in which Gust head and producer for this title Junzo Hosoi and development producer Yasunori Sakuda both offered commentary on what happens in it.

As for the early purchase bonus, it gives us two costumes and a pack of items. These are basically active looks for exercising for the two leads. Slade can wear Fresh Trainer and Rias can wear Passion Runner. The Adventuring Charm Set in the bundle gives us a Training Charm that boosts XP earn and a Victor’s Charm that boosts SP we get.

Here’s how the costumes look: 

As a reminder, this game did have ties to Atelier Resleriana: Forgotten Alchemy and the Polar Night Liberator. That appeared on PCs and mobile devices. However, it is no longer available, as Koei Tecmo shut the global version down back in March 2025.

The Atelier Resleriana: The Red Alchemist and the White Guardian will appear on the Switch, PS5, and PC worldwide and on the PS4 in Japan, and the release date is September 26, 2025.
