The author began writing the series in 1974, when she was just 14 years old.
At the beginning of the series, the author went by the name Tamaki Shin, but has since changed her pen name to Yasay Kemonogi. Therefore print editions of early volumes have a different author name than the digital editions, which were published later under the author's current pen name.
