Udo is 12 years old, he may not have been the most confident soldier, but he had a heart of gold. Despite his occasional moments of uncertainty, he was always eager to help those in need, especially when it came to tending to the wounded. He’s apathetic, depressive, and he is also prone to being angry, snide and sarcastic rather than being fearful and cringing. While Udo's nervous disposition may have occasionally caused him to overlook the needs of those he was treating, his caring personality.
