About This Game

"Shake up the flow, blend the rhythm."

This is the one and only absolute rule of Nastrond.

In the chaotic Middle World, there is a single neutral zone established by a diverse gathering of beings. They call it the 'Oasis'.
Nastrond is a bar nestled in the corner of an alley within the Oasis.
Beings from various dimensions visit this place to unfold their stories. They challenge the bartender to a rhythm duel—if they win, their drinks are on the house. But if the bartender wins, the cost of the drinks goes straight into the bartender’s tip jar.

■ The Oasis's Only Human Bartender, 'Ray'

You will take on the role of 'Ray', the only human in the Oasis and the newest bartender at Nastrond. By winning rhythm duels against the guests, you will earn the right to hear their stories.

"What am I supposed to do... from now on?"

The story begins after Ray follows 'The Master', the owner of Nastrond, and crosses over into the Middle World.
As of now, you do not know why she ended up in the Oasis, why she carries a bass guitar, or how she came to work as a bartender at Nastrond.

■ Become the Bartender of Nastrond!

Now that you are a bartender at Nastrond, you must welcome various guests, accept their rhythm duels, and start shaking.
Do not forget Nastrond's one and only absolute rule:

"Shake up the flow... blend the rhythm...!"

As Nastrond's bartender, you cannot back down from a guest's challenge.
When the LP starts spinning on the vintage record player, grab your shaker and ride the rhythm.

■ Resonate with the Shaker as the Notes Pour Down!

When the music starts, you must hit the falling notes with precise timing.
Experience the satisfying, crisp feedback—as if you were actually mixing a cocktail—within a familiar and intuitive keyboard-style rhythm game system.

As you strike the notes to the beat, the shaker will slowly begin to resonate. Once it reaches perfect resonance, a flawless cocktail is made.
The rhythm varies depending on the song and the guest, so you cannot let your guard down for a single moment. Never let the momentum break.

However, be warned that there may be 'traps' hidden among the falling notes. Filtering out the dissonance and picking only the true rhythm is the ultimate measure of a bartender's skill.

(Do not let the guest's momentum overwhelm you!)

(Shake the shaker perfectly to the rhythm!)

■ Two Ways to Enjoy the Night at Nastrond

Nastrond offers two core game modes tailored to your playstyle.

• [Scenario Mode]
  The main story content progressing from the perspective of 'Ray'. Win rhythm duels to serve a perfect glass, and listen to the private worries and wishes your fantasy guests confess as the drinks loosen their tongues. Enjoy an ever-deepening narrative served alongside your cocktails.

• [Arcade Mode]
  A mode for players who want to purely focus on the fun of the rhythm action. Freely select and play the charming tracks you've unlocked through the story, push your limits, and chase those high scores.

■ Nastrond Continues to Grow

The following features will be introduced at official launch or through sequential post-launch updates:

• [Arcade Mode Ranked System]
  Beyond simply enjoying the music, we plan to introduce a ranked system where you can compete against bartenders worldwide. Check the leaderboard to see who can mix the perfect cocktail.

• [Gallery & Jukebox]
  We are preparing an event CG gallery and a jukebox so you can revisit the precious moments and music you encountered in the story whenever you want.

• [Costume & Play Skin Customization]
  We are developing a feature that allows you to customize the outfits of Ray and her companions, as well as personalize note designs and hit effects to match your own style.

No one knows who will walk through the doors of Nastrond next.
Furthermore, no one knows what kind of stories 'Ray'—the Oasis's only human—will encounter, or what cocktails she will craft.

But one thing is certain: you are holding a shaker engraved with the Ouroboros symbol.
Now, shall we recite Nastrond's absolute rule one more time?

"Shake up the flow, blend the rhythm."
