Seri Awashima holds the vital position of second-in-command within Scepter 4, functioning directly as the right hand to leader Reisi Munakata. She executes missions with cool efficiency and a detached demeanor, often appearing indifferent to civil rights during operations. Despite this outward coldness, she consistently prioritizes non-lethal solutions over lethal force. Physically, she is a tall woman standing 170 cm with a curvaceous figure. Her bust measurement is a point of discussion; former high school acquaintances refer to her as "Awashima the Hundred," implying 100 cm, while she personally claims it is 95 cm. Her documented full body measurements are 95-57-92. As a member of the Blue Clan, she wields Blue Aura abilities. Her aura manifests as thin, bluish wisps capable of scorching terrain, even wet grass, often leaving trails of smoke. She complements this power with considerable swordsmanship skill, typically fighting using a saber. Beyond her duties, she is a regular patron at Izumo Kusanagi's bar. Her preferred drink is a martini incorporating red bean paste, reflecting her specific personal taste.
