Serious and pure love story about an otoko no Ko (boy in girls clothes) and young girl.

The sky was blue as far as the eye could see.
But the window was shut, and no breeze can be felt.
Rations are almost gone...

it's a world of just the two.

Toya and Ayaka wait quietly in a single room.
They wait for a visit...

------

They will scatter the "life plans".
It's a vengeance carried through generations, the final gasp of the god-forged "helix mystery".
They will destroy the system that dominates their life.

Rain spits down from the sky... there's color.
It's clear rain. But with a tinge of blackness.
It speckles the ground and glass on the window and disappears, but it's there. The rain falls black.
As if dead, to bear the plain truth like the vast horizon, one can only keep it private.

Tayo remembers a passage from the book.
Great catastrophe will befall us, and humanity will suffer.
Are we in the final war? Or if we survive it, will there be a savior to take us to the new age?
