Sharpen your blades and step inside the Eternal Palace.
Eternal Palace Sakura is a 3D action roguelite from the indie team Denneko Yugi, published by Shochiku. You play as Retla, a cat-eared girl who fights her way through an endlessly shifting dream labyrinth where restless yokai never sleep. Every floor rearranges itself, every battle hands out attributes, and every attribute teaches you one of more than fifty fighting arts. There are over twenty enemy types, frenetic boss fights, and a great deal of hand-crafted cutscene at the end of the road. It launched on Steam on November 4, 2026 and on Nintendo Switch the very next day.
The official description asks you to pick a lane: play for speedy evasions, power straight through the enemy, or charge up an attack to sweep them away. Combos are built for the tap of a button, so the difficulty is in the routing, not in the execution.
Attributes drop from both combat and exploration, and each one teaches a new fighting art. That is a lot of unlockable depth for a roguelite — enough that the second run plays nothing like the first.
Twenty-plus enemy types inhabit the palace, from wandering yokai to the things that guard the deeper floors. Reading their tells is the whole game once the combos are muscle memory.
The Eternal Palace rearranges itself between runs. There is no fixed map to memorise, so the route you take is as much a build decision as which attributes you spend them on.
Eternal Palace Sakura is a 3D action roguelite developed by the indie team Denneko Yugi and published by Shochiku, the long-established Japanese film company that now runs a games division. The copyright line on the official site reads simply "©Denneko Yugi", which tells you how much of this is the small team's own work.
The premise is short enough to state in one line and deep enough to keep a wiki busy for years: Retla, a brown-skinned, cat-eared, hooded girl, sharpens her blades and steps into the Eternal Palace — a dream labyrinth that never stops changing, inhabited by monsters that know no rest. You fight, you explore, you collect attributes, and those attributes teach you fighting arts. At the far end of all of it is content that exists specifically to be hard.
What the game does not do is hide the difficulty. The official copy talks about "exciting endgame content" and "over twenty different enemies and frenetic boss fights" in the same breath as the charm. The visual side is deliberately cute — the store tags include Cute 3D Fighter and Anime — while the animation quality and the hand-crafted cutscenes are pitched at a much more expensive-looking game than an indie roguelite normally gets.
It released on Steam on November 4, 2026, with the Nintendo Switch version arriving on November 5 — a genuinely day-and-date launch, which is rare for an indie action title of this size. The Switch launch price was $9.99 in North America against a normal $11.99, with a further 20% off running through November 18; the Japanese digital list price is ¥1,500 including tax. Supported languages are Japanese, English, and both Traditional and Simplified Chinese, with Japanese voice audio and full subtitles throughout. Steam features include achievements, cloud saves, family sharing, and full controller support.

That 50+ fighting arts figure is the single most important number for long-tail search traffic. A game with fifty unlockable combat techniques produces fifty separate searches of the form "Eternal Palace Sakura [technique]", and almost none of them are answered well by anyone else yet. That is where a dedicated wiki earns its keep.
