The dead keep coming. So you keep growing.

You are alive in a place that wants you dead. Fight your way through Yomi with a samurai's blade, a miko's seeking cranes, or an onmyoji's spells.

Your weapon attacks automatically. You steer through the horde, collect jade, choose its next upgrade, and decide when to unleash your ultimate.

One weapon, a build of your own

Make a close-range slash reach across the fight. Send more cranes after fleeing enemies. Add orbiting attacks, follow-up strikes and spell effects. Growth changes how your weapon fights, as well as how hard it hits.

At weapon level 10, a guaranteed upgrade choice offers awakening. Take it to change your character's form, strengthen their attacks and unlock a more powerful ultimate. Pass on it, and it can appear again in later upgrade choices.

Three ways to break through

• Samurai: draw the blade in any direction. Awaken to sweep a lightning arc, then split the battlefield with One Cut.
• Miko: let seeking paper cranes chase your targets. Awaken to command a golden flock and a storm of rotating cranes.
• Onmyoji: weave talismans and spell attacks. Awaken to call down an astral seal and leave a ward that damages and slows enemies.

All three are available immediately. Each ultimate leaves a short-lived advantage after its cinematic impact: take that moment and push back into the horde.

In the free demo

• 73 weapon traits, including awakening, with additional attack forms and set transformations.
• A first goal of 20 floors and four great yokai; continue into endless mode after clearing it.
• Souls, permanent upgrades, and gems to equip or fuse between runs.
• Eight interface languages: English, Simplified Chinese, Traditional Chinese, Japanese, Korean, Russian, Spanish and Brazilian Portuguese.
• Japanese ultimate voices with translated subtitles. Separate music, effects and voice settings, plus a master sound switch.

The first 20 floors contain 12 minutes 45 seconds of scheduled combat time. Upgrade choices, cinematics and boss encounters can make a run longer. The demo does not stop at a 15-minute timer.
