One of the many ways in which Sarah's differing stories are visually represented are her many different outfits. The major ones we've seen, her traditional princess outfit, warrior outfit, mage outfit etc.
But showing growth visually is something that's going to keep being a part of the game as the story evolves. Concretely, I can share 2 current upcoming new outfits. They are still being worked on, but I think they are far enough to communicate their basic ideas:
The first design is Sarah's sailor outfit, for the story-arc that takes place when she departs Lethram along with Belmont on his ship. For the upcoming update, that is how that route starts, but in the future there will also be a way to start that route without engaging with Belmont.
The second design features Sarah in an outfit that suits the climate of the deep desert where the Tribes reside. Though I don't think climate-concerns were the primary consideration in designing these clothes.
This outfit plays a big part in the route where Sarah loses the war to the initial invasion, a future update that I hope will be ready to share with you all quite soon.
These outfits are hardly the sum total of all the various outfits that are planned, but I hope they give you a good insight into how even Sarah's own design will continue to grow along with the story itself.
Any particular outfits/themes you'd hope to see in the game one day?
