Shūko Komi, born Nimi Shuuko, shares an uncanny resemblance to her daughter Shouko, with dark purple-black hair, sharp eyes, and a perpetually youthful demeanor she humorously attributes to being “forever 17.” Her vibrant, extroverted nature starkly contrasts the reserved personalities of her husband Masayoshi and children, cementing her role as the family’s primary social anchor. Gifted with effortless charisma, she navigates conversations with ease, channeling her warmth into unwavering support for her loved ones. Shaped by early hardship, Shūko endured the loss of both parents in childhood and was raised by her grandmother, whose death during her high school years plunged her into isolation. This solitude ended when Masayoshi’s marriage proposal offered a lifeline. Prior to their union, Shūko exhibited a detached, kuudere persona—cool, aloof, and emotionally guarded—during her school days. Her initial indifference faded as she grew intrigued by Masayoshi’s quiet resolve, sparking a transformation into the affectionate, open-hearted woman she is today. As a mother, Shūko champions Shouko’s quest to conquer social anxiety, enthusiastically embracing her daughter’s friends, including Hitohito Tadano and Najimi Osana, into their home. She openly acknowledges Tadano’s positive influence, earnestly entrusting him with Shouko’s continued growth during a sincere exchange. Unperturbed by her mother-in-law Yuiko’s chilly demeanor, Shūko radiates cheerfulness during family gatherings, even when clad in traditional garments that draw Yuiko’s silent disapproval. Her maiden name, Nimi (“new view”), and married name, Komi (“old view”), whimsically mirror her journey from solitude to connection. A devoted cook and cat enthusiast, she bridges generational divides, bonding effortlessly with Shouko’s peers. Within her narrative, Shūko embodies resilience, her life a testament to familial devotion, the power of communication, and the transformative impact of love amid loss.
