Arimura Yu, a freelance writer, wrote an article about So Ra No Wo To
for an online magazine Men's Cyzo. He researched whether the first title of "Anime no Chikara" project was successful or not.
Last summer, TV Tokyo and Aniplex launched a new timeslot "Anime no Chikara", which is dedicated to original anime. The purpose of the project was to promote the creativity of the anime industry and to encourage the production of original works. Sora no Woto was extensively publicized as the first title.
However, the alteration of Kishida Meru's original character designs and the resemblance to K-ON! caused criticism before the airing. When the series began in January, the high quality of the art and the animation had received some praise, but the discrepancy between the dark memory of war and the calm descriptions of the slice of life perplexed the audience. Akai Toshifumi, the animation director of Sora no Woto, reacted to the criticism against the happy ending by saying "People won't be moved nor consented unless someone dies. Why aren't they impressed by the character's survival?", and his post inflamed the anime fans even more.
According to unofficial data, the first week sales of Sora no Woto volume 1 were 3,057 copies of Blu-ray with a few hundreds of DVDs. The number can be regarded as a moderate success as an original anime and proved that there does exist a certain demand for original works.
