Yuuta's mother, the matriarch of the Togashi family whose full name remains unspecified, possesses brown hair and green eyes. Standing approximately 160 cm (5'3") tall, her youthful appearance often leads to confusion that she is her children's older sister. With her husband working overseas primarily in Jakarta, she serves as the primary caretaker for their three children: Yuuta, the older daughter Kuzuha, and the youngest daughter Yumeha. She later relocates to Jakarta with Yumeha to join her husband, while Kuzuha returns to Japan to continue her schooling.

Her personality radiates warmth, carefree energy, and playfulness. She frequently engages in lighthearted teasing of Yuuta and Kuzuha, though Kuzuha typically finds this annoying rather than embarrassing. Working in the medical field, she maintains a traditional yet approachable demeanor. Deeply devoted to her family, she prioritizes their well-being over her own needs, providing crucial emotional stability during her husband's absence. She accepts Yuuta's past struggles with *chūnibyō*, recalling that delusional phase with amusement and describing it as "not so bad," a view contrasting sharply with Yuuta's own embarrassment. Her support extends to understanding his difficulty moving beyond his past; she refrains from pressuring him to conform to societal norms, instead accepting his individuality.

Narratively, she functions as a confidant for Yuuta, offering him a safe space to discuss his fears and challenges. While her direct involvement in the main plot is minimal, she subtly influences character dynamics, such as foreshadowing Yuuta's eventual relationship with Rikka Takanashi during early episodes. Her relocation to Jakarta reduces her onscreen presence in later story arcs, yet her foundational role in establishing familial stability remains vital to Yuuta's development.
