Ending - Nio

This is a list of all the necessary events required to achieve Nio's ending in Atelier Ayesha: The Alchemist of Dusk.

While Nio does not technically have an ending that can be chosen at the game's end, Nio's events are required for the "Girl's Gathering" ending. Triggering all of Nio's events will unlock the "Flower Smell" and "Sister's Thereafter" trophies.
