Baba Takahiro, the President of Visual Arts, tweeted on his Twitter account that he and the staff of Visual Arts shared the anxieties and expectations among the fans over the production studio of the Little Busters! anime. However, he made a decision when he saw the enthusiasm of J.C. Staff and Warner Bros. Japan for producing the TV anime. He said J.C. Staff and Warner were great companies and asked the fans to trust them.

On the official twitter account of Key, one of the staff explained the production policy of the Little Busters anime. Although the order of the events might be different from the original game, there won't be alterations in the story nor anime original characters. He said the length of the TV series is significantly long, but still it was necessary to shorten the original story to adapt it to the limited number of episodes. He added that the relationships among Rin, Komari, and other new members of the Little Busters team might be described more in detail than in the game.
