Lead developers of Castlevania: Belmont's Curse have spoken about the process that led to the creation of Rose Belmont, the game's protagonist. Initially, they didn't have a specific gender for the protagonist in mind, but after developing the story, they wanted to base it around the strong bonds between mother and daughter.
In an interview with Famitsu, as translated by GamesRadar+, director Yukiko Hokao explains how the process of developing Belmont's Curse began without a specific protagonist in mind. "At the start we hadn't decided that the protagonist would be a woman," she says. "While we were building the world and the story, we thought the role would best suit a woman, and it was decided that it should be Trevor Belmont's daughter."
