Essential 4★ Radiatio healer whose Second Heart state heals the team over time, stacks up to +12% team ATK (1.5%×8), and reduces team DMG taken by 20%.

"Dispensing drugs, performing surgeries, chemical analysis, forensics... I'm the only person in this city who meets all your needs, no?" Her July 30, 2026 dossier dubs her 'The Medical Lancet' - a coroner, surgeon, and blunt friend who spends every day around corpses, reading the last truths left behind by the dead. An earlier preview sheet gave her an even colder quote: "Life hasn't been kind to me. Death, on the other hand... has been a truer friend." Sharp-tongued and unsentimental, Firtho runs private medical experiments in the hidden back rooms of The Corner Clinic and knows exactly where to cut when a fight starts. Because of a congenital illness, she's hooked up to a life-support rig at all times, and she despises anyone who pities her for it. On the field, she's a Radiatio Guardian under the Survival & Healing style who fights with an amputation saw and syringes, and her Skill 'Second Heart' is the only direct party heal in the game.
