"This is Arnaud." A man wearing a corporal's uniform introduced. The man was none other than Corporal Verrau, who had last been charged with cleaning up the site of a battlefield. And in that chaotic environment, he had found a boy who had returned from the brink of death.
Corporal Verrau requested a prolonged absence from his duties due to the boy, and was luckily granted to him. As he was in a non-essential position behind the frontlines, it was easy to secure this.
When the boy initially woke up, he had a mild concussion that had caused him to suffer temporary amnesia according to the medics. Verrau jumped through all sorts of hoops to get him to remember his name, but alas, it was of no success. He ended up giving the name Arnaud to the boy, which was his great-grandfather's name.
