The player character is Retla — a brown-skinned, cat-eared girl in a hood, who fights with dual blades. That is the entire character description the publisher leads with, and it is enough to tell you the shape of the game: one character, one weapon pair, an enormous amount of variation layered on top through the fighting arts system.
Retla's combat is built on "flashy dual-blade combat" with fast dodges, and the game's own store tags list Hack and Slash, Fast-Paced, and Character Action Game. Publishers describe it as "Demon Slayer meets Hades", which is a useful shorthand for the fantasy even if the mechanics are closer to a character-action roguelite than to either of those two games specifically.
What that means in practice: you are mashing out a combo chain, you are choosing between three ways to engage, and the game trusts you with a small number of inputs so that the flow stays fast. The depth lives in which fighting arts you have layered onto the chain.
The three routes are evasion, power-through, and charge-up, and they are not classes — they are three different answers to the same fight. Nothing stops you from mixing. What the attributes and fighting arts do is let you lean into one of them so hard that it becomes your style, and the game advertises more than fifty fighting arts precisely so that "my style" can mean something different from one player's run to the next.
The narrative frame is that Retla is walking into the Eternal Palace, a dream labyrinth that constantly rearranges itself, and that her goal is to reach its core. The official site describes it as "an endlessly changing labyrinth inhabited by fearsome monsters that know no rest". Expect the story to be delivered through the hand-crafted cutscenes the publisher emphasises, and expect the bulk of your time to be spent in motion rather than in dialogue — this is a gameplay-forward action game that happens to have a story attached.
