Rosehip serves as commander of St. Gloriana Girls College's Crusader Tank Platoon as a first-year student. She possesses medium-length wavy pinkish-red hair, amber eyes, and an average height, wearing the standard St. Gloriana Sensha-do uniform with high boots.
Her personality radiates high energy and spontaneity, marked by an obsession with speed in all activities—even eating—developed from growing up in a large family of eighteen members where rushing prevented being last. She exhibits extroversion, fearlessness toward failure, and minimal concern for social approval. Darjeeling acknowledges these traits as valuable for St. Gloriana's Sensha-do team despite Rosehip lacking the school's typical grace and elegance, leading Darjeeling to provide special etiquette training.
In the *Drama CD*, Rosehip witnessed St. Gloriana's early practice match against Ooarai but did not participate due to unmet standards. She later joined the semi-finals against Kuromorimine as a scout in a Crusader tank, though her unit was likely destroyed.
During the *Girls und Panzer der Film* exhibition match against Ooarai/Chi-Ha-Tan, Rosehip commanded a Crusader Mk.III. Her speed initially distracted opponents, but reckless maneuvering caused her to collide with Klara's T-34/85, triggering an explosion that buried both tanks. She survived and was later accidentally knocked out by a stray shot. In the annihilation match against the All-Stars University Team, she temporarily transferred to Ooarai. After supporting Team Morning Glory, she disabled an M24 Chaffee via a mid-air attack while jumping a canal, destroying her own tank and becoming St. Gloriana's last survivor.
Within the manga *Motto Love Love Sakusen Desu!*, she visited Ooarai and was reprimanded for running in corridors. She reconciled with Klara about their collision. Attempting to emulate Darjeeling, she mistakenly confessed love to Assam, causing confusion. Darjeeling later affirmed Rosehip's inherent worth during a piano session.
In *Ribbon Warrior*, she fought under Orange Pekoe's "Chindits" unit in Tankathlon matches, commanding a Light Tank Mk.VII Tetrarch. She used a kukri knife to clear jungle vegetation and eliminated an enemy column from behind. After shielding Orange Pekoe against Bonple High School, resulting in her tank's disablement, both joined Bonple for the Cauldron Tournament.
Trivia notes her namesake (rose hip tea), use of the high-society speech suffix "desu wa," and role as a mechanic for the Crusaders. Her tank's removed speed governor—historically increasing speed—symbolized restraint and mirrored her bold tactics. She also holds the distinction of being the first tank knocked out by Momo Kawashima.
