The protagonist of the series; accidentally teleported into the future from his "home", Tokyo, he ends up having to fight in Hamdo's army, where many soldiers are mere children that have been captured from villages the army conquered. With his outsider attitude, he stands out from the crowd, having an unusual amount of kindness and manners in comparison to the other children. Despite being a kendo fighter he's extremely clumsy, overly enthusiastic, and overtly optimistic, which usually causes him trouble as he's often being tortured, interrogated, or otherwise getting in trouble. 

Shu is a typical Japanese boy, but has an unbeatable, optimistic and determined attitude. However, when he sees a mysterious girl with strange eyes named Lala-Ru up on a smokestack, he is soon pulled into a strange desert world. Shu soon discovers the true terrors of war, which includes genocide, brutal torture, hunger, thirst, and child exploitation. Now Shu is trying to save Lala-Ru, as well as his hard earned, and often relunctant, new friends from the insane dictator, Hamdo. Whether Shu can possibly accomplish saving those he cares about while still holding up to his values remains to be seen. <br><br>
