Honkai: Star Rail just dropped a nuclear drip marketing post revealing Firefl as the first playable character of patch 2.3. Firefly's backstory is shrouded in mystery. She was created as a weapon and suffers from a condition called Entropy Loss Syndrome, which is a result of her genetic modifications. She fights relentlessly to find a cure and defy her predetermined fate and we are likely to get more details about her backstory in patch 2.2 leading up to her release in 2.3.
Honkai: Star Rail 2.3 Firefly Official Drip Marketing
"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, Firefly is 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.

Going by previous drip marketing patterns, Firefly will be the first character to debut and we will get a second character revealed tomorrow. Leaks suggest that Jade will be the second new character of the patch but we need to wait for an official confirmation by Hoyoverse.
