Description
Mayumi Saegusa, Student Council President of First High School from 2093 to 2095, formed the "Triumvirate" with peers Juumonji Katsuto and Watanabe Mari as one of the academy’s three most formidable third-year students. Renowned as the "Elven Sniper" for her mastery of long-range precision magic and the "Elven Princess" for her striking beauty, she stood out as a prodigy within magical circles. Her appearance featured jet-black hair, crimson eyes, a petite 1.55-meter frame, and a proportionally ample bust, with limbs elongated relative to her height.

As the third child of Saegusa Kouichi, leader of the Saegusa Family among the Ten Master Clans, she held the role of eldest daughter in the main family, flanked by two older half-brothers and younger twin sisters Izumi and Kasumi. This position cemented her reputation as a rising star. During her presidency, she actively challenged First High’s discriminatory division between Course 1 and Course 2 students, striving to reform systemic inequities.

Confident yet mischievous, Mayumi blended playful charm with a subtly sadistic edge, exemplified by her tradition of gifting bitter Valentine’s chocolates. Though initially coy, she gradually revealed her authentic self to trusted individuals like Shiba Tatsuya. Rare genuine praise from him disrupted her usual poise, while subtle jealousy surfaced when he complimented others, hinting at unspoken affections. Her father sought to exploit this dynamic by proposing a political union with Tatsuya to weaken the Yotsuba family, though her personal motives remained distinct.

A specialist in tactical long-range magic, Mayumi wielded "Dry Meteor," conjuring high-velocity dry ice projectiles through carbon dioxide manipulation. Her innate "Multi-Scope" ability granted multi-angled sensory perception bypassing physical barriers, while "Psion Bullet" disrupted magical activations with surgical precision. She maintained her own CAD, earning Tatsuya’s respect for her technical skill.

During *The Girl Who Summons the Stars*, Mayumi orchestrated evacuation efforts and engaged Japanese Navy aircraft using her Magic Bullet Shooter to protect Kokoa, a fugitive from experiments on Strategic-class magic subjects. Her actions underscored strategic brilliance and dedication to safeguarding the vulnerable.

Post-graduation, she declined arranged marriages, enrolled at Magic University, and later joined Tatsuya’s Magian Company at her father’s behest to assess its agenda. However, upon grasping Tatsuya’s vision, she chose to remain aligned with her own principles, cementing her role as both ally and independent agent.
