Firefly will finally be playable with the Honkai Star Rail version 2.3 update! Check out the Firefly Kit, Materials, Traces, and more here to find out if she is worth your precious Stellar Jades.

Honkai Star Rail – Firefly

“Fireflies are such magical creatures, aren't they? They may throw themselves at a flame or suddenly grow old, but every night before that, they will shine brighter than the stars.”

A member of the Stellaron Hunters and a young girl clad in a mechanical armor “SAM.”

Born as a weapon, she's afflicted with the agony of Entropy Loss Syndrome due to genetic modification.

She joined the Stellaron Hunters in search of the meaning of life, relentlessly pursuing ways to defy fate.

Mentions of “Sam” have been in the game since its release, but we only got to see him in action in Penacony. Firefly was initially thought of as a completely separate character when she was introduced in Version 1.6 along with Penacony.

Firefly is a 5-star Fire character on the Path of Destruction. She becomes playable on Honkai Star Rail version 2.3, scheduled for June 19, 2024. This makes her the first character in this archetype. She follows Hook as a Fire Destruction character, but Hook is a 4-star character.

Firefly is a member of the Stellaron Hunters, alongside Kafka, Blade, and Silver Wolf, among others. She carries out the Destiny's Slave's script as SAM, an armored mech that doubles as the life pod sustaining her.

She hails from Glamoth, a fallen interplanetary nation. It's mentioned in the Planar Ornament Set “Firmament Frontline: Glamoth” which shows a mech (probably SAM, or a similar model) hung up with a lot of wires.

Who are the Firefly voice actors?

For the English voiceover, Firefly is voiced by Analese Fisher. She's an on-screen actor whose previous roles include Kendall from Metal Lords, Beth the Time Keeper from Craig of the Creek, and Rowan Shaw from Crazy Fast. Her other video game roles include NPCs Salmon Eri and Mirai from Genshin Impact, Snow Sugar Cookie from Cookie Run: Kingdom, and Anke from Lost Ark.

She is joined by Adin Rudd who plays Sam in the English voiceover. His previous roles include Beelzebub from Granblue Fantasy, Lauriel from Lost Ark, and Gallant B from Tiny Tina's Wonderlands.

Firefly's Japanese voice actor is Tomori Kusunoki. Her previous roles include Llenn in Sword Art Online Alternative Gun Gale Online, Makima in Chainsaw Man, Misha Necron in The Misfit of Demon King Academy, and Kirara in Kirara Fantasia.

Sam's voice actor in the Japanese voiceover is Jun Kasama. His previous work includes Gintama, Cells at Work!, Demon Slayer, and Overlord.
