Miwako Inagaki (稲垣=美和子, Inagaki Miwako)
“What's wrong, Daddy...? ...Mommy, Daddy's crying.”
She first appears in the park with her mother and younger sibling, noticing her father sitting on a park bench and pointing it out to her mother. Aizawa is brooding over having just left the Japanese Task Force. Yumi approaches him and he informs her that he is taking time off.
An excited Yumi asks if this means he will be home now, and he says that he will. He picks her up and tells her that now he can spend more time with her and do things like take her to the zoo and the amusement part before breaking down into tears.
Yumi has short, chin-length, brown hair and brown eyes.
