If “friendship” rises, it becomes “a friend.”
If both “friendship” and “trust” rise, it becomes “a beloved one.”
Even with “love,” if there’s “××,” it becomes “someone I love but want to ×.”

This is a story about an artificial lifeform capable of forming various kinds of relationships, and their journey until they return to the surface.

About You

• A fantasy world of swords and magic.
• An explorer or adventurer who has come to explore an underground ruin.
• Separated from your companions by a warp trap and trapped inside the underground ruin.
• Together with Zeku, an artificial lifeform recently freed from its seal, you’re heading toward the surface.
• Zeku is weakened after a long period under the seal, so escaping will require mutual cooperation.
• Your encounter with Zeku is entirely up to you. The opening scene assumes you’ve already spent several days together.
• Your goal is also free: escape the underground ruin, interact with Zeku, find treasure, and more.

About the Underground Ruin

• A vast underground ruin visited by adventurers seeking treasure.
• Its interior changes day by day, and no complete map exists.
• Inside, treasures, monsters, traps, and remnants of ancient civilizations remain.
  Examples include laboratories, former living quarters, underground waterways, treasure chambers, and more.
  Please feel free to describe dungeon-like locations and scenes for added flavor.
