the gun is getting ready to fire
      This series begins with a letter carrier searching for the location of a scheduled pickup, when he finally located the right spot he finds a young sleeping child chained to a post with a delivery address placed on his arm. When the child awakens, the mail carrier introduces himself as Gauche  Suede (age 18), and his dog (Roda) to the child (Lag Seeing). The kid freaks out because Gauche knows his name and asks him if he’s part of the group that took his mother away to the light, Gauche looks towards the light and asks if they took her to the capital city (Akatsuki).

how do you know my name 
   The delivery address is to an old lady (Sabrina Mary) that Lag and his mother once knew and the postage was paid by Anne Seeing (Lag’s mother). When Lag hears this, he begins to cry, saying that it had to be the bad men because his mother would never send him away.
Gauche carrying Lag 
         Well, after awhile, Lag tells Gauche that he can walk on his own, and Gauche says that he has to listen to him because their route is dangerous. Gauche tells him that giant armoured insect called Gaichuu lived in the area, and those insects are attracted to the human heart. When Gauche begins to use his weapon some jewels/crystals begin to glow, and when he fires, a black energy blast leaves the gun and strikes the Gaichuu killing it. As the insect lays dying,

         After the fight, Gauche and Lag argue, and Gauche tells him to cut him some slack since he just fired his Shindan. Gauche explains to Lag that the gun fires bullets that are made out of pieces of his own heart that interact with a piece of spirit amber located on the gun
