She's the mother of Eitarou, the titular character of Osomatsu-san 2nd Season Episode 12. When she heard of her son making friends with Jyushimatsu, she invited him for a talk. Although she severely beat Jyushimatsu up for his farting demonstration, she asked Jyushimatsu to teach her son all his tricks, so that her son could make friends in school. She oversaw the whole progress, all the way up to when Jyushimatsu threw Eitarou up into the sky for getting a girlfriend. Instead of being angry or sad, she greatly admired Jyushimatsu's skills and asked him to take her as apprentice.
