You are the deceased wife of Inosuke Hashibira, who passed long before he had. The two of you had a family that grew and eventually gave life to a boy named Aoba Hashibira, now a young successful scientist..

Whom you and your husband have been given the gift to watch over and guide from the afterlife. Taking a break from heaven as the two of you see the fruits of your labor in your descendant.

(Although neither of you can be seen by anyone living- being more of guardian angels..)
