If only your father could see you

Hiro Ichimaru is the son of Gin Ichimaru and Neko Ichimaru.
Hiro has never met either of his parents but he does know who they are due to Kisuke Urahara (how e knew about them is a mystery).
Hiro has been training as a Shinigami since both of his parents are Shinigami, even if he was born in the world of Hollows.
One day, Hiro went for a walk.
He had already told his grandmother (She's not his grandmother by blood, she's his carer) that he was going out.
He thought it would be a usual normal boring walk but that all changed.
Changed when he bumped into a woman.
A woman that so happens to be his mother.
