These include Alexandrite in Land of the Lustrous, Lieselotte Sherlock in Trinity Seven, Cinscetta in Assassins Pride, and Kurinon in Log Horizon Season 2, among many others. Their work often involves collaborations with the same group of voice actors, directors, and ADR writers within the Texas-based dubbing industry, frequently working with directors such as Kyle Colby Jones and Christine Auten. This pattern of recurring collaborations is typical for voice actors who work regularly with specific dubbing studios.
