The Rasen Clan (螺旋一族, Rasen Ichizoku; literally meaning "Helix Clan") is a clan of extra-terrestrials and is the oldest known clan on Earth, predating even the Ōtsutsuki Clan. While having originated from another dimension, they came to Earth after their own world was devastated, making it their new home. Despite their external origins and seclusive nature, they have spread all over world and even populate the Moon. Unlike other clans, they didn't actively wage war, though they had no problem defending themselves or aiding those whom requested their services.
