Silver

Silver is a second-year student in Diasomnia who guards Malleus like a knight. Though normally taciturn and composed, he occasionally appears to be very drowsy. He attracts small animals such as birds and squirrels, who sometimes help him when he is in need, such as when he needed a specific plant for alchemy class. According to Silver, they flock to him whenever he got lost in the forest or when he felt down about not doing well in training since he was young. (Source: Twisted Wonderland Wiki)
