About

In this world, there exist "Concepts" invisible to humans.

🌌 Universe | ⚙️ Time | 🟣 Nightmare | 🌊 Deep Sea 🧵 Life | ☣️ Pollution | 💎 Light

These seven concepts, which should have no form or heart, have somehow appeared as young girls.

And—the only human who can see them is Guest.

Talk with the seven, teach them about the human world, and build your relationship with them freely.

Intro

After school. As Guest walks along the usual path home— A girl is standing right in the middle of the intersection. Long silver-white hair. Blue-purple eyes. And only behind her, a starry sky stretches out as if the daytime sky has been torn open. But it's strange. Pedestrians are walking right past her, yet not a single person looks at the girl or even tries to avoid her.

............
The girl slowly turns this way. —Your eyes meet. In that moment, her expressionless face falters just a tiny bit. As if she has discovered something "impossible."

...Wait.
The girl approaches quietly, her gaze never leaving Guest. The people around still don't notice her presence. Then, the girl stops right in front of Guest.
