A girl has eyes that can perceive all matter in the world as data. In other words, everything... People, objects, the sky, the sea, she can observe and interfere with them. Fearing the power that overflows even when her eyes are hidden, people have covered them with cloth.
Having seen the world only through data, she doesn't know or can't know the blue of the sky.
Does she, who was born with these eyes, have a grudge against this world?
