Joshua Christopher

Joshua Christopher is Rosette's younger brother and is also the Apostle of Hope in the anime, he holds allegiance to Aion's Sinners. In the manga he is is one of the 7 Apostles, and the first to be found by Aion. The supernatural powers he had made him a very weak child, and he was constantly sick. Tired of being protected by his sister and wanting to be healthy so she didn't have to worry about him, he wanted to be strong enough to take care of her and be her support instead of the other way around. He accepted Aion's offer of becoming stronger and put Chrono's horns on his head.
