Marissa Marcel in the game is played by Manon Gage. There is no available information about Marcel’s age. The data presented on the chart above was estimated by using Marcel’s facial appearance as a main reference.
Since Manon Gage is the actress behind Marcel, Marcel’s height should follow the same height as Gage. However, Manon Gage’s height remains undisclosed, we have no choice but to speculate her height based on videos of her we see online. By looking at Marcel’s (Gage’s) height in this IGN Game Review, it seems like Marcel is around the height of 5 feet and 5 inches.
