[Key][MU]Planetarian ~The Reverie of a Little Planet~

The unceasing Rain──
The 『sealed city』,
abandoned 30 years ago after a sudden biochemical warhead strike.
The uninhabited ruins,
ruled over only by autonomous battle drones.
The man came to this place,
finding shelter inside a tall building as he grew exhausted,
and there he came across
a planetarium,
a room that once filled the hearts of men
with the wonders of all the stars in all the sky.
And there, he met a young woman
whose name was 「Reverie」.
A member of the planetarium's help staff
who had continued to wait for customers for over 30 years;
a broken robot──
Entreated by 「Reverie」,
he lost track of time as he repaired
the nonfunctional planetarium projector.
The continuous Rain.
Those quiet days spent with 「Reverie」.
A long-lost nostalgia that began to arise in the man's heart.
What will he think about this sky of manmade stars?
And what is the fate of this 「Reverie」 of a little planet?
