Tastuo donated money to a charity. He did this in memory of Akiko. The charity has nothing to do with Akiko, does it? Please kindly help on this again. Thank you very much.
Often, donors to charity will do this to recognize someone else (who might be dead), even if the other person is not related to the charity. It doesn't serve a purpose except to publicize the deceased person's name. I guess this is one way charities try to get donations by offering the chance of publicizing a name of the donor's choice.
