What's Nana's sister's name?

Nanako's full name in Japanese is Nanako O 'Hara: ぉぉはらなこなこどなこなここな.

In the episode of Crayon Shinchan, Shinchan got up early one day, walked in Xiaobai, met Miss Nanazi, and went for a walk together after meeting. But Xiao Xin didn't get up the next day.

When Xiao Xin got up, it was far beyond the appointed time. He was so depressed that he made up for the scene when Nana was angry and said that he was a child who didn't accept the agreement. At this time, Nanaz came to Xiao Xin's home.

Xiao Xin came to the porch and saw Miss Nanaz's eyebrows drooping.

Then he received a beautiful flower.

Nana's sister told him that she saw this when she was walking today. Because it is so beautiful, she wants to make a gift for Xiao Xin. Instead of blaming the five-year-old for not getting up at six, she said to Xiao Xin: Although it's a pity today, let's go for a walk together tomorrow!

It can be seen that she really takes Xiao Xin seriously. After all, I'm just a child, and I'm not interested in this. Really a kind and gentle girl.
