Curte the Clear Sky is a character who appears in the dark fantasy anime series Ishura. Her history is defined by profound loss; she lost her hometown and was also deprived of her sight at the hands of the entity known as the True Demon Lord. In the aftermath of this tragedy, she was taken in by Taren the Punished and came to reside within a tower located in the central fortress of the New Principality of Litia.

Her personality is gentle and soothing, a quality most evident in her use of her beautiful singing voice. Within the confines of her situation, Curte plays the role of a source of comfort. She shares a longtime friendship with Regnezy the Wings of Twilight, and it is her singing that serves to soothe him. The memories she holds dear, particularly those relating to Regnezy, are carefully recorded in her diary.

Curte’s role in the larger narrative is tied to her function within Taren's plans, as she is used to help control an army of Wyverns. Her fate is tragic. An attempt was made to save her life by a character named Kuze, but this effort ultimately failed. In her final moments, her last words were a plea for the safety of her mother, delivered to Taren, asking her to save her. A key relationship is with Taren the Punished, who took her in and raised her, making Curte refer to her as a mother figure. Another significant relationship is her long-standing friendship with Regnezy the Wings of Twilight, whom she supports through her singing.

In terms of notable abilities, Curte does not possess combat-oriented powers. Her primary gift is her voice. Her beautiful singing is her most defining ability, which she uses to soothe her friend Regnezy and is also instrumental in controlling the Wyverns, making her a non-combat asset with a unique and valuable function within the military strategy of Litia.
