Background

Despite her youth, she serves as president of a renowned cosmetics company, initially supported by the Okura Family but later made successful through her own management ability.

Personality

Behind her poised exterior, Rumin has a teasing and emotionally reactive rapport with Talent. She can become dissatisfied when his attention shifts toward other girls, yet later takes the initiative to ask to stay with him after missing their previous intimacy. 264 731

Story Role / Major Arcs

Revelation of Her Status

Rumin first appears as an imposing black-clad woman whose warning leaves Talent, Utaha, Eriri, and Megumi relieved once she departs. Talent then reveals that she is both his great-aunt and childhood friend. Her position as a young corporate president and member of the Okura Family further establishes why the others find her intimidating. 176 177

Ouka Mai's Introduction

Rumin accompanies Iyo to Talent's home when Ouka Mai is brought to meet him. She immediately evaluates the similarities between Mai and Talent, including their appearance, family backgrounds, and exceptional abilities. 206

As part of the household group, Rumin welcomes Mai in French and helps create an environment where Mai can loosen the “perfect” persona that leaves her lonely. 208

Developing Intimacy with Talent

Rumin remains part of Talent's close personal circle, with their interactions often mixing provocation and embarrassment. Her flustered response during Rina's verification call suggests a significant private encounter with Talent, and she later visits his apartment specifically to ask to stay overnight. 520 731
