Shūko Komi, born Niimi, embodies youthful charm with her vibrant demeanor and striking presence. Once a rebellious high schooler, her life shifted upon falling deeply for Masayoshi Komi, whose quiet stability tempered her spirited nature. Despite embracing domesticity as a devoted homemaker, she playfully clings to her self-declared age of 17, channeling her lively energy into cat-themed hobbies and culinary expertise, which she uses to nurture her family and bond with others. Her effortless charisma and warm communication skills starkly contrast her daughter Shōko’s social anxiety, yet Shūko patiently uplifts Shōko’s confidence through shared moments—especially their mutual adoration of cats. Balancing her husband’s reserved personality with her own vivacity, their partnership thrives on complementary contrasts. She navigates tense visits to the Komi estate with poise, unshaken by her stern mother-in-law Yuiko’s frosty demeanor, often disarming formal gatherings by donning a kimono. When meeting Hitohito Tadano, her daughter’s first friend-turned-boyfriend, Shūko greets him with a heartfelt bow, radiating gratitude for his role in Shōko’s growth. Her journey—from defiant teen to reformed romantic and steadfast mother—highlights her adaptability and layered resilience. Notably ranking 8th in a character popularity poll, Shūko’s legacy extends beyond her narrative, with voice actor Ikuko Inoue’s casting adding depth to her portrayal. Her story weaves familial devotion, personal evolution, and unwavering encouragement for her daughter’s strides toward connection.
