Intelligent summary
  • Kazuma Kaneko's Tsukuyomi is a tactical deck-building tower dungeon RPG that launched on Switch in April 2026 and reaches Steam today.
  • Gameplay centres on a strict three-card hand, persistent Creation Cards across runs, and a multi-perspective story set inside a sealed Tokyo megastructure.
  • The title continues Kaneko's signature blend of global myth and dark fantasy, moving on from the earlier free-to-play version to deliver an offline, story-driven experience.

Kazuma Kaneko has spent decades crafting worlds where ancient forces wear modern menace. His latest, Tsukuyomi, now steps onto Steam after landing on Nintendo Switch in April. The timing feels deliberate, a continuation rather than a rush, and it carries the quiet confidence of someone who understands how Japanese game design earns its staying power.

The game casts players as elite agents of the Tsukuyomi organisation. They infiltrate THE HASHIRA, a sealed megastructure rising over a near-future Tokyo. Combat unfolds through Jinma Cards in tight turn-based exchanges. A strict three-card hand limit forces every decision to matter. Between runs, players shape persistent Creation Cards that carry forward, turning each ascent into a layered experiment in deck-building and adaptation. The story splits across four agents, offering overlapping perspectives on the same tower and its secrets.

Kaneko himself handled concept planning, world design and character creation. That continuity shows. The Jinma echo the distinctive demon aesthetic he refined across the Shin Megami Tensei and Persona catalogues, here fused with a roguelike tower climb that rewards precision over spectacle. It is superb but never showy, content to let systems and atmosphere do the heavy lifting.

The original free-to-play Tsukuyomi: The Divine Hunter used generative AI for assets and ran on live-service foundations before shutting down shortly before this paid edition launched. The new Tsukuyomi distances itself cleanly. It is offline, story-focused and built from the ground up with refined mechanics. COLOPL maintains its own AI policy for its games; the shift to a traditional, crafted experience reads as a return to fundamentals that have sustained Japanese development through cycles of hype and correction.

Language support covers Japanese, English, Korean, Traditional and Simplified Chinese, with full Japanese and English audio. On Steam, buyers can choose the standard edition or a digital deluxe bundle that includes two DLC packs under the Painter K's Divine Brush: Manifestation of Truth Set. The second volume, adding fresh Creation Cards inspired by figures such as Arianrhod, Raphael, Banshee, Apollo and Satan, arrives alongside the base game on both platforms.

Initial plans called for a simultaneous global launch. An update in July adjusted that for North America, Europe and Australia, sliding the Steam release into autumn or winter to allow time for local customer support. The decision feels pragmatic rather than hesitant, another reminder that lasting work often prioritises readiness over speed. The core creative thread remains intact: a Japanese studio letting a veteran artist define the aesthetic and systems on their own terms.
