Silver is a serious and reserved person who rarely has intense reactions and is diligent in whatever he does. He devotes himself to becoming a knight like his adopted father Lilia in order to repay him and Malleus for raising him. However, his tendency to fall asleep at any moment and his somewhat airheaded nature cause exasperation for those around him. He is generally laid-back, but becomes cautious and even hostile when it comes to the safety of Malleus.
