The game's developer LINUJ described Sora as an "ambiguous person to call the protagonist", considering Yuki Maeda to be the main character overall. Worrying that people hadn't grown attached to Sora by that point, he intended to change that with Chapter Four by having Sora be a part of the murder plan and causing a reaction in the group once this was revealed: LINUJ specifically described it as an "I believed in this person" type of scenario. The original version of Chapter Four would have had the possibility of Sora's character changing as well. When the chapter was changed during development, this change in character was no longer possible. It's left ambiguous what would have happened to her character had the original version of the chapter been used.
