is concerned, Marona is the only one able to see Ash in phantom form. This is primarily because of her unique ability known as "Chartreuse Gale". This ability not only allows her to see and interact with phantoms, but bind their souls to various objects to grant them a temporary body, referred to in-game as "Confine". Using this power she can summon Ash and other phantoms to the world of the living to aid her in her own endeavors as a Chroma, similar to the work done by her late parents. Because she possesses the ability to see and speak with the dead, many assume that she is either controlled by or cooperates with evil spirits, and are afraid to even interact with her, much less employ her for Chroma work.

Marona leaves Putty—a mischievous nature spirit found on an earlier assignment—with Castille to keep her company when Marona is unable to do so. As the game progresses, signs of Sulphur returning to Ivoire in full force become more apparent.

At one point Marona and her rival Walnut are forced to team up, and it is revealed that Walnut is Castile's older brother who's been stealing money from Marona and other Chromas in an effort to pay for Castile's hospital bills so that she can be cured of the sickness that keeps her bedridden. Ash and Marona meet more people who are
