“How do you do, Professor Rean? I am inexperienced, but I look forward to your class.”
- —Musse's intro quote, Trails of Cold Steel III
Musse Egret is a main character in The Legend of Heroes: Trails of Cold Steel III. She is enrolled in "Class IX: Accounting Division".
Musse is a young woman of a slender build with green hair and light fuchsia eyes. She wears the standard issue academy uniform of Thors Military Academy's II branch.
Although she receives good grades and has the grace of a noble’s daughter, there is something unfathomable about her, as she tries to seduce newcomer professor Rean at every opportunity.
She previously attended Saint Astraia Girls’ School in the Imperial capital, but dropped out after the Civil War due to various circumstances. Half a year later, and suddenly aspiring to walk the path of a soldier, she is admitted to Thors Academy's Leeves II Campus.
Musse is reported to be a noblewoman who had suddenly disappeared from her home, apparently staging her death. She is actually from one of the most high ranking noble families of Erebonia.
In half of Trail of Steel 3's story during the Lamarre noble conference, She reveals herself as "Mudine Useif Du Cayenne, the previous duke cayenne's daughter who was believed to be dead due to some accident after the Erebonian civil war. Due to this reveal with help of Jusis , Angelica , Patrick and Aurelia she got re-instate back into the head of Cayenne's family instead of her uncle who take over the family after the civil war.
