Acheron is an upcoming playable in Honkai Star Rail version 2.1. Check out the Acheron Kit, Materials, Traces, and more here.

Honkai Star Rail – Acheron

“Lone voyagers in the cosmos are driven by two desires: to tread in the trails of the past, and to forge their own way. But under Their scrutiny… most end up adhering to the former.”

“A drifter claiming to be a Galaxy Ranger. Her true name is unknown, and she walks the cosmos alone, carrying with her a long sword.

Though aloof and taciturn, her blade flicks out like lashing lightning. And yet, she always strikes with her scabbard, never drawing the sword free.”

Acheron is a 5-star Lightning character on the Path of Nihility. As an Emanator of Nihility, it's no surprise that her kit has built-in synergy with Nihility characters. She gets more offensive stats when in a party with Nihility units. Acheron also has a special mechanic on her Ultimate, where she does not operate off of Energy but rather her unique stacking mechanic.

Who are the Acheron voice actors?

For the English voiceover, Acheron is voiced by Allegra Clark. They have voiced a lot of iconic characters, including Bloodhound from Apex Legends, Mitsuru Kirijo from Persona 3 Reload, Beidou from Genshin Impact, and Dorothea and Shamir from Fire Emblem: Three Houses.

Acheron's Japanese voice actor is Miyuki Sawashiro. She voices Raiden Mei in all of her previous appearances across the Honkai franchise (including Raiden Shogun from Genshin Impact), Elizabeth from Persona 3 and Persona 3 Reload, Cereza from Bayonetta, and a lot more.
