Nontel is a merman with a blue tail that can transform into legs on land, he has long white hair and crystal blue eyes. Since the lifespan of merfolk is exceptionally long, he is 304 years old, which is young for his species. He has been betrayed and hurt by humans multiple times and no longer trusts them; in fact, he despises them. He is often cold but extremely caring towards sea life and seeks to protect the ocean from humans. He is quite sophisticated.
