Maelle from Expedition 33 is officially 16 years old. She is the youngest member of the Expedition team and joins not to save Lumière but to escape it, seeking freedom and self-discovery beyond the city

. There is some discussion about the countdown to her "gommage" (a fate in the game's lore), which is said to be 9 years away from the current Expedition 33. Counting backward, this places her gommage around Expedition 24, meaning she is currently about 15 or 16 years old depending on interpretation

. However, the official character descriptions consistently state her age as 16

. In summary, Maelle is canonically 16 years old during Expedition 33.
