Wiene is a mysterious female Vouivre born in the middle floors of the Dungeon. It is later revealed that she is one of the Xenos.
Wiene has the ability to speak even though she is a monster due to her being a Xenos. She is kind, helping a young boy even though people regarded monsters as evil. Wiene grew attached to the Hestia Familia, particularly Bell and Haruhime. Wiene doesn't like to wear clothes, as she refused to wear them and she even tried to get rid of the cape she was wearing due to the hot temperatures she was not used to before being convinced to keep it on. Originally, Wiene had more of a cowardly nature, influenced by all of the evil intent people had toward monsters, including the citizen's rejection of her even though she saved a boy. However, after she was reborn, she becomes much more courageous, reminding herself that Bell saved her even though people would scorn him for it.
