Description
Urara Oikawa fulfills the role of school nurse at St. Mihailov Academy, distinguished by her purple hair typically secured in a bun, green eyes, and frequent attire of a lab coat. She maintains ties to the organization Athos and holds deep knowledge regarding Qwasers and their conflicts, rooted in her past collaborations with Shinichiro Ootori and Yuudai Yamanobe on research projects. Her duties include treating students wounded in battles and dispensing personal counsel, though she displays a recurring fixation on breast measurements, often performing checks under the pretense of ensuring proper bra fittings while exhibiting her own physique.

Urara shows protective instincts toward Tomo Yamanobe, Yuudai’s daughter, striving to shield her from traumatic incidents like Astarte’s transformation during the Theosis Project. Two weeks after Tomo’s kidnapping, she established direct contact with Sasha, disclosing her history and familiarity with Yuudai while supplying a special book that unlocked a concealed compartment housing documents on the Theotokos of Tsaritsyn. Medically, she healed Tasuku Fujiomi and Mutsumi Sendou following their confrontation with Jita and Milk, overriding Mutsumi’s attempt to provide soma due to weakness and offering her own instead—an act that incited Mutsumi’s jealousy. During the worldwide activation of the "Sword of Maria" sealed within Mafuyu Oribe, Urara underwent soma extraction alongside Yuri Noda.

When Mafuyu later sought advice on breast reduction after the Sword of Maria’s deactivation, Urara dismissed any possibility of restoring their former size. In the second season, she treated Jita and Yumie after their collapse near the academy, explaining the device implanted in Jita’s breast and cautioning against Qwaser abilities to prevent soma accumulation. She subsequently aided Tomo and Jita against thieves stealing student body measurements, providing Tomo with an egg-shaped elemental circuit that transformed her into "Mademoiselle Tomo," unleashing breast-based energy beams that subdued the thief but depleted Tomo’s energy. Other brief involvements included distributing a breast enlargement book to Hana and Fumika and accompanying a group visit to the academy’s hot springs.

In the OVA *Jotei no Shozo* (Portrait of the Empress), she performed medical examinations with Teresa, utilizing Lulu Shiizaki’s ill-fitting bra to demonstrate proper breast measurement techniques while displaying her own figure. She also intercepted Sasha and Ootori during their attempted peeping. Her smoking habit ceased in the anime after Sasha criticized it for tainting soma, though it continued in the manga. Her documented physical measurements are 98-59-88.
