Photographer Katerina Danielyan, also known as "katya sfotkai krasivo," loves storylines featuring two mirrored characters. For example, in the action RPG Genshin Impact these are Lumine and Aether, and in the manga "Chainsaw Man" — Yoru and Asa.
She held a photoshoot during which cosplayers Nikkol and Alisa Dvachevskaya appeared as Stelle and Caelus.
This refers to the Trailblazer, the main character of Honkai: Star Rail, whom players can choose at the beginning of the game: Stelle is the female character, Caelus is the male one. It is this protagonist who boarded the Astral Express to eliminate the dangers posed by the Stellaron.
The Trailblazer can use the following combinations of Paths and damage types in battle: Destruction — Physical, Preservation — Fire, Harmony — Imaginary, Remembrance — Ice.
