Project SEKAI: Memories Across the SEKAI

SEKAI Memories

**One forgotten song. Five wounded worlds. Twenty-six voices waiting to be

remembered.** ♡

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.

Story

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

Travel through seven independent dimensions:

| SEKAI | Atmosphere |
|—|—|
| School SEKAI | School halls, rooftop, garden and music rooms |
| Stage SEKAI | Concert stage, dressing rooms, seating and lights |
| Street SEKAI | Night streets, cafe, live house and neon alleys |
| 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 |

The five group SEKAI physically evolve as the story progresses. Wounded places
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.
