The story is set in a town that preserves nature and its natural attractions using technology. It centers on a protagonist who has drifted apart from his childhood friend, and uses the FlatFormer to reconnect through time and space.
As far as anime commercials go, this was quite better than my expectations. They managed to have a definite story in less than 7 minutes quite well. However, the constant guitar sound in the background during the middle feels unnecessay. Thankfully it stops just when you'd want to click off the video. If this were an OVA or even a decaminute longer I'm pretty sure the story and characters could've been explored a lot better
