Synopsis:
A small, deep, outbreak forest that is not reflected in the radar.
There was a warm organic matter that reminded me of something important, forgetting a boring and ruthless job.
I don't know the coordinates. In order to get there, I felt only the smoke and the sea breeze for a long time, and it was the best signpost (Michirabe) to recall the nostalgic sensation in my smell and be honest with myself. 。
However, the fragment of the living memory, which should have been left somewhere, does not know that it will bring a great fluctuation to the end of this country in this world.

The future a little ahead. A world that has fallen into the war state of the muddy due to serious food shortages. On a small, deep, and a deserted isolated island that does not exist on the map and is not reflected on the radar, a blonde girl, Lulu, who lives quietly with her uncle, comes regularly. The name of the "visitor" is Saito. This is the only strongest weapon in this world.
