Airi Midorikawa

"He's my son. I'll decide what to do with him."

- to Miharu Kuroda

Airi Midorikawa is the blood mother of Shinobu Yosomono.

Background
Airi's childhood is relatively unknown. At the age of 21, she became a heavy addict to alcohol, spending most of her time at the local bar. Attempts to get a proper job commonly ended in failure, as she was fired from every one of them due to her drinking habits. Even so, she continued to feed her addiction, even while she became pregnant with four children. As a result, one of them developed an unknown heart disease a few years after birth.

The cost of taking care of four infant children, along with the cointinous spending on beer and alcohol products began to take its toll on Airi. Eventually, in order to save herself money, she decided to send her children away to seperate foster homes. She had successfully done so with all except Shinobu Yosomono, before her sister Miharu Kuroda finally intervened, offering to adopt the boy instead. Not wanting Shinobu to be influenced by Miharu, Airi resisted, resulting in a bitter conflict between the two that was taken to court. Eventually, Airi finally granted Miharu permission when she paid her 200 dollars, in exchange for parental guidance of Shinobu.

Her current location is unknown. However, it is assumed she has continued her drinking habits.
