Emi is Baki's mother, though her relationship with him is complicated at best. Before settling down with wealth and marriage, she apparently worked as a prostitute. Everything changed when she and her husband spotted Yujiro during a vacation—she became instantly infatuated with him. When her husband objected and struck her, Yujiro killed him in retaliation, breaking his neck. Rather than traumatize her, the incident sealed her obsession. She fell in love with Yujiro and committed herself to raising Baki as a warrior in his image.
But her devotion curdled into something darker. Over time, her love transformed into obsession, and she never showed Baki genuine affection or warmth. When Yujiro eventually abandoned them because he felt Baki wasn't skilled enough, Emi's resentment shifted entirely onto her son. Fans often note that she becomes one of the story's most toxic influences on Baki's life, driven by her fixation on a man who never truly wanted either of them.
