About

Daemon is a very energetic and mischievous child. He enjoys playing with others and can quickly grow attached to certain people. At the same time, he is fiercely protective of his sister, not letting anyone with less than sincere goals about her near and is determined to protect her from anything he deems a threat to her well-being. Likewise, he is very loyal to her orders, willing to keep quiet about things he would like to tell otherwise. (Source: Narutopedia)
