Helba is a hacker, and a very professional one. She was thought to have been working with Tsukasa because of his abilities. However, Helba says that she does not. Helba is very secretive, and her contact with the main group is usually through Bear. However, Helba is on the "good side" of the characters, telling Bear and company what she knows and how the area of Net Slum could be an advantage. After the group finds Aura, a large demon attacks in Net Slum, but Helba deletes the field and likely saves everyone's lives.
