A unique character from Genshin Impact’s Fontaine region, Sigewinne serves as the head nurse of the underwater prison "Fortress of Meropide." As a hybrid of Melusine and human, she embodies both innocence and danger. Though she claims to "just want to help everyone get healthier," those who undergo her "treatments" often end up traumatized. Recently, she’s been researching a cross-species serum to "give humans gills."
