Arisa Glennorth is a character from the anime Stellvia. She is a teenage girl with red hair cut to shoulder length and blue eyes. Her birthday is on October 4.

Arisa is best friends with the protagonist, Shima Katase, who is often called Shipon. The two first meet on the shuttle traveling from Earth to the space station Stellvia at the start of the academic term. Upon arrival, they discover they have been assigned as roommates and are also in the same class, a coincidence that quickly cements their close bond.

In terms of academic and piloting ability, Arisa is not as naturally gifted as her friend Shima. However, rather than being discouraged by this difference, she views Shima as a source of inspiration. She affectionately calls Shima her "Star of Hope" because Shima's dedication and skill motivate Arisa to work harder and improve her own capabilities. As the series progresses, Arisa reevaluates her career path and chooses to shift her focus away from becoming a pilot. Instead, she begins concentrating on the field of mechanics, finding a different way to contribute to the operations of the Stellvia foundation. Her key relationships are centered on her friendship with Shima and her interactions with her classmates within the foundation.
