Mangaka Haga Yui posted on her twitter that she wanted to pay off the huge debt of the Astarotte no Omocha! anime. She regretted that she couldn’t return profits to those who invested in her work. She herself purchased five copies each of the Astarotte no Omocha! Blu-ray and DVDs. She said she will do her best to promote the anime.
