In their search for food, they find a raft to take them beyond this unknown place, but it becomes evident that only one person will be able to board this raft.

Set in the near-future, a little-understood form of matter known as "Mile One" allows a powerful and influential Japanese family, the Gowa, to produce a bipedal weapon which they refer to as a Tactical Armor (TA).

When US military forces attempt to seize the capital, they are systematically wiped out by what appear to be rival TAs. The Gowa Family seizes this opportunity to demonstrate their weapon system, and civilian pilot Yuushiro Gowa and the military squad to which he is attached are deployed to Belgistan. There, he meets rival TA pilot Miharu, with whom he seems to share a deep spiritual bond.

The village’s most infamous man, Shan Gou, used to go up into the mountains to hunt wild animals every day. Recently, however, something seems to have frightened him so much he isn’t willing to even stay out late at night...
