The Red Ranger Becomes an Adventurer in Another World: Ayumi Asagaki

She's Togo (Red's) biological mother who took good care of her son. Sadly, she wasn't given an actual name in the manga (Ayumi is her given name in the anime) and not much known about her except that she owned a cafe and her husband was a detective. She and her husband were killed in an car accident when their son was young (around 9 years old). Because of their tragic deaths, Togo was orphaned until he met Daigo of the Shindo family, who was a friend of his parents. This is from Episode 12.
