Welcome to **Memories Across the SEKAI**, a Project SEKAI fan mod for Minecraft
1.21.1 that brings together story, rhythm gameplay, card collection, world
exploration and cozy building.

Miku is trying to reach you from a fragmented world. Travel between the SEKAI,
meet their residents, recover their memories and create a unique bond with the
girl who refuses to let their song disappear.

## ♡ A Story To Remember

**Memories Across the SEKAI** features a complete six-chapter campaign.

- Follow Miku's fading signal.
- Make choices that change later dialogue and memories.
- Discover four variants of the final scene.
- Complete a personal quest for each of the 26 characters.
- Fill your Memory Album with letters, scenes and photographs.
- Take part in a special Final Live.
- Unlock a post-story epilogue and the title **The Voice That Remembers**.

Your first login is more than a simple notification. The world reacts to your
arrival, a voice crosses the silence and Miku leaves you two unique keepsakes:
her **Letter Between Worlds** and the **First Memory Fragment**.

## ✧ Explore The SEKAI

Travel through seven independent dimensions:

| SEKAI | Atmosphere |
|---|---|

| Wonderland SEKAI | Castle, circus, rides and a colorful park |
| Empty SEKAI | Broken islands, silence and isolated spaces |
| Broken SEKAI | The mysterious center of Miku's story |
| My SEKAI | Your own peaceful world to build |

begin to heal, new details appear and their residents slowly return.

Each group world also has its own non-positional Minecraft ambience, controlled
through the normal **Music** volume slider.
