Cherche is a former vassal of House Virion from Rosanne, and the mother of Gerome. Her wyvern mount is named Minerva. Despite her domestic nature, she is surprisingly strong as she gained her vicious dragon mount by defeating her and surviving her fire breath, only getting a burn scar on her shoulder (a bald spot in the Japanese version) from the encounter. When she was only nine years old, though as her supports with Nowi shown, Minerva was sick and thus weakened at the time. Her support with Gaius reveals that she detests fighting, but the only reason she does is so she can live to see her family again. In her support with Gregor, it is revealed that Gregor betrayed a former employer of his in Wyvern Valley to save a then baby Minerva from being killed. In the A support conversation with Vaike, Cherche tells him that she found Minerva in Wyvern Valley as a child, and that she trained as a Cleric using a heavy staff and disciplined Minerva with the staff when she misbehaved.
