Delia Ketchum

Hanako Delia Masami Ketchum, from Pallet Town in the Kanto region, was the mother of Ash Ketchum.

Background
Delia became pregnant at the age of 19. The father of her child abandoned her, so she ended up raising Ash by herself. They always lived in Pallet Town.

About a year before the start of Tears of the Fallen, Delia was having trouble keeping up with the taxes for the Tekiyoku. After repeated warnings and deadlines missed, an unknown Tekiyoku member(s) murdered her.

Character
Not much is known about Delia. However, Ash lives on the memory of her very well. She was clearly a great mother to instill such positive values in Ash. Ash always wants to help others, even at the expense of inconveniencing himself.

Ash mentioned that Delia always wanted him to stay happy and he goes on to stay positive in life even despite the trauma he went through when he lost her. Ash misses her deeply and uses what happened as motivation to help make the world right.
