Kono Aozora ni Yakusoku wo

After several non-adult ports of the original adult visual novel, each of which included new subtitle, the PlayStation Vita version was released with the same title as the original. While the new character from PSP version is not included in the main story, the PlayStation Vita release has redone graphics for high-definition resolution, and features five new episodes written by Fumiaki Maruto (丸戸史明).
