Atelier Karia's roster is the largest the series has fielded for a modern entry — eight playable characters, two antagonists and three named non-playable allies, all with confirmed Japanese voice actors.
| Character | Role | Japanese CV |
|---|---|---|
| Karia | Protagonist. Aladiss Pioneering Team member; an amnesiac adventurer who can eat and analyse almost anything | 浅見香月 (Asami Katsuki) |
| Servio Lektor | A heretical biologist who loves all living things; speaks as if performing; his past is a mystery | 玉木篤志 (Atsushi Tamaru) |
| Fina Rozen | Cheerful, open knight with surprising strength in a slight frame; accepted a special duty from the team leader | Lynn |
| Yumia Liessfeldt | The alchemist who solved the Aladiss mystery two years ago; Karia's mentor | 倉持若菜 (Wakana Kuramochi) |
| Noelk Schreiber | Inspector for the Eustellan Bureau of Alchemical Relic Control; formerly an archaeologist | 千葉翔也 (Shoya Chiba) |
| Celes | Lives in a Noctrem village; skilled in cooking and tea, and a sword master | Fairouz Ai |
| Lenja | Of the Welcks female race; Pioneering Team member; investigated Aladiss with Yumia two years ago | 青山吉乃 (Yoshino Aoyama) |
| Rutger Arendt | A veteran adventurer who assisted Yumia; sold memories in the slums as a child | 福山潤 (Jun Fukuyama) |
A note on Karia's voice credit, which is inconsistent across official sources: the official English character page writes "Kazuki Asami" while the TGS 2026 official page writes "Katsuki Asami". The Japanese original is 浅見香月, which reads Asami Katsuki. Asami, Lynn and Fumimura also performed live at the TGS stage event on September 20.
Read as a group, the eight cover a deliberate spread. Karia is the generalist without access to her own expertise; Lektor is the heretic scientist who talks like a performance; Fina is the straightforward knight; Yumia is the senior authority and mentor; Noelk is the institutional inspector; Celes is the grounded local expert who cooks and fights; Lenja is a non-human perspective from the Welcks; and Rutger is the criminal past and the veteran. Notably, two of the eight — Celes and Fina — are also the two characters with dedicated swimwear sets and the two with save-linked costume bonuses alongside Karia and Yumia, which is a decent proxy for who the marketing treats as central.
| Character | Role | Japanese CV |
|---|---|---|
| Crave Fortis | A masked alchemist guarding the giant dragon that may be the cause of the mana withering; his intent is unclear | 小山力也 (Rikiya Koyama) |
| Lyvel Ventus | An alchemist with blades on her legs; outwardly composed with a volatile temper; travels alongside Crave | 中場真由美 (Hitomi Nabatame) |
Both antagonists are alchemists, and both guard the same dragon. That is the story's central asymmetry: the protagonists are alchemists too, on the opposite side of a resource question. Signa's grudge against the beast gives the scenario its third axis — a Noctrem native who wants the dragon dead for personal reasons, while the two alchemists who guard it will not say why.
| Character | Role | Japanese CV |
|---|---|---|
| Ernest | An automatic doll guarding an underground workshop, self-described as an "ultra-high-specification self-disciplining automatic base management device"; says he lacks a heart | 高橋慎也 (Shinya Takahashi) |
| Signa | A young man met in Noctrem who wants revenge on the giant beast that destroyed his home village | 村瀬步 (Ayumu Murasaki) |
| Viktor von Duerer | A knight of the Order of Eustella and leader of the Aladiss Pioneering Team; took over from his predecessor Erhard | 古川真琴 (Makoto Furukawa) |
No character's combat kit, stat line, weapon type or personal questline has been published, and it is unknown whether all eight are playable in every chapter or whether some join later — given the reveal schedule (four in June, two in September, two at TGS), the party assembles over the story. What is also unconfirmed is the Antagonist designation in the game's own terms, the endings per character, and whether the endings are mutually exclusive. The roster may also still expand — this list reflects the state as of November 12, 2026.
