Sakurako, Japanese: さくらももこ, real name Miura Miki, the family runs a fruit and vegetable store. 1984 after the official debut, in 1986 under the pen name of Sakurako, began to draw the manga "Sakurakumaru" based on the experience of childhood, the main character's name is also Miura Miki's pen name, the protagonist of the main character's birthday is also Miura Miki's birthday. Sakurako's lively and witty writing style made "Cherry Maruko" popular in Asia outside of Japan.

But the story behind the manga is surprising to read Many of the characters in "Cherry Maruko" have archetypes in real life. For example, the brooding Nagasawa-kun is indeed a real person. When Sakurako attended a reunion, she got the date wrong, arrived a day late, and met Nagasawa-kun, who had come to pick up his hat, and wrote a little article about it. Hamasaki-san is also archetypal, and he himself published a book called "I am Hamasaki". And the rich Hanawa-san is actually a total Missy. On top of that, Mariko's best friend Jade, Inuyasha, her dad Hiro, her grandfather Tomozou, and another close friend of Mariko's who doesn't show up much, Kayoko Yamada, are all present.

In the anime, Mariko's grandfather Tomozou often plays with her, always looking like a yummy kid and never criticizing Mariko. Her mom often gets angry and says that her grandfather is too spoiled for Mariko. In short, the grandfather in the manga is a very kind person. But the truth is that Grandpa's personality is completely different The real Tomozou is actually a very stubborn, bad-hearted old man that Mariko and her sister hate, and the only thing that's the same as in the manga is that they are both Alzheimer's patients. As for the manga's Grandpa Tomozou, it's just author Sakurako's own "ideal grandfather".

Isn't the backstory a surprise!
