Kusunoki Akane

She disappeared shortly after the protagonist was born (or so we are told).

Recently, Akane reunites with the protagonist through an artificially mistaken e-mail. Did the protagonist, who knew nothing about her, see an image of his “mother” in her when he met her for the first time?

Or was it purely his interest in women which started his physical relationship with Akane.

From Akane's point of view, there was a part of her that was not even allowed to see her son. Perhaps her smoldering affection burst and she could no longer stand it.

But either way, the way she loved him was distorted. No matter the methods, her desire to seek out the protagonist is apparent.
