When the Count offers the swordsman as a sacrifice, Slan explains to him that only something precious to him will suffice. While standing by, she watches in awe as Guts fights through his multiple injuries toward Femto, expressing her excitement at the idea of him joining her ranks. Two years after the Eclipse, Slan and the rest of the God Hand are summoned by the Count, who having been fatally wounded by Guts, requests new life. Despite the turn of events, she and her kinsman are left unfazed and welcome the coming of the Age of Darkness following the birth of the fifth.


When the Skull Knight intervenes and spirits Guts and Casca back to Physical World, Slan is left surprised and admits that the God Hand cannot foresee every possibility. After Griffith reaffirms his ambition and sacrifices the Band of the Falcon, Slan expresses an interest in Guts' vain attempt to save Griffith, and later sheds a tear while watching her newly reborn kinsman Femto sexually violate Casca, describing it and Guts' violent reaction as a thing of beauty. Using an area of land in the Interstice as a temporary vessel, she manifests a gigantic form of herself. Once the guest of honor and his sacrifices appear before them during the Eclipse, Slan is the first of the God Hand to materialize. Slan and the other members of the God Hand first make themselves known to Griffith during his imprisonment in the Tower of Rebirth, greeting him as their kinsman and foretelling his forthcoming audience with them. A precious sacrifice, so that he may become a demon. I am sure you will make for an excellent sacrifice. However, Slan has actively influenced humanity through the cult of the Goddess of Flame, who have held cannibalistic pagan blood orgies in her honor. Much like her fellow senior God Hand members, Slan's past life as a human is unknown. She notably brings up Guts' intent of killing Griffith, suggesting that he should use the beherit in his possession to do so. 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. 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. She personifies lust and the evils associated with it, describing Femto's rape of Casca as a thing of beauty. 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.
