Helen

Age: 12

Birth Place: A small volcanic island in the Mediterranean sea.

In the anime, she was the granddaughter of a local chieftain who was killed by two Silver Saints, Agora and Shiva, for hiding Ikki from the Sanctuary assassins. Helen was thrown alive inside of a volcano when she attempted to help Ikki too, but she managed to climb her way up the volcano's walls and her struggle boosts Ikki up enough to kill Agora and Shiva and free Helen's village.

Apparently named after Helen of Troy, the famous Queen of Sparta.
