During an interview with GayGamer, Grandpa Pixel confirmed that one of the main protagonists, Atesan Turwin is gay. They also stated that they wanted to bring in more LGBT ideas for the storyline as they felt it was ideal to have it in a series that explores time travel which allows them to explore how equality evolves over the course of centuries.
It was also confirmed that Atesan would have a darker story than most protagonists are exposed to. The developers felt that while they wanted Tetiro to be the protagonist that grows with the player, they wanted another main protagonist who has already experienced the rough parts of being a hero and an outcast. Something they know happens in other countries just because of their sexuality.
