Slan is a member of the God Hand, and in particular the only female member of the group. Slan is a sadomasochist who thrives on cruelty and the effect it has on others, having influenced the foundation of pagan cults who know her as the "Goddess of Flame" and revere her through cannibalistic blood orgies and drugs that open a person's mind to visions of the future. She personifies lust and the evils associated with it, describing Femto's rape of Casca as a thing of beauty. Her perspective is perverted to the point that even being ran through the abdomen with the Dragon Slayer while in one of her manifested forms merely arouses her. Slan also appears to have a lustful fascination with Guts since first meeting him during Griffith's Eclipse, referring to him as "darling" and expressing interest in his resilience and fortitude, while finding his inner darkness to be most appealing. She notably brings up Guts' intent of killing Griffith, suggesting that he should use the beherit in his possession to do so.
