BWH: 92-56-94
Asako raised Yuuji after his parents died, taking on the role of his guardian with a complicated mix of strictness and affection. She instilled her own values into him pretty deeply—enough that he can function normally in society, though he developed a lasting wariness around intimidating women, which fans often note comes directly from his time under her care. Her parenting style was genuinely inconsistent; she could be capable one moment and completely hopeless the next. Her cooking skills were particularly legendary in the worst way—she couldn't even pull off basic fried rice.
Outside of raising Yuuji, Asako was pretty unremarkable in her own right. She shared his love of reading and was happiest just settling in with a book, cigarettes, and coffee, especially on lazy rainy days when she had nothing else to do. It's the kind of simple contentment that defined a lot of her personality.
