Nishio Shinobu's Monogatari series was a series of novels that featured a Japanese high school girl, Aryo Ryagi, as the main character. They included " Hua Monogatari,"" Fruit Monogatari,"" Thousand Monogatari,"" Monogatari Series," and " Ball Mill River." The creation of the monogatari series was inspired by Nishio Fuxin's own experiences as well as some events and cultural phenomena in Japan. Although the Monogatari series had a high literary value and a large number of fans, its animation had always been a controversial topic. Nishio Shinobu himself had hinted in his works that he was cautious about adapting the novel into an anime because he was worried that the anime would lose its original literary style and meaning. At present, some of the works in the Monogatari series had been adapted into anime, such as The Story of Hua Monogatari and The Story of Guo Monogatari. The future adaptation of works such as Thousand Monogatari, Monogatari Series, and Ball Mill River was still uncertain, so it was still a controversial issue whether they could all be animated. Although the Monogatari series had a high literary value, there were still many challenges and difficulties in anime. Therefore, whether or not to fully anime it still needed to consider the decision of the producers and authors.
