Three episodes to build a time machine that works backwards through emotion instead of physics. The animation moves like nothing else from 2014, all precision and weight, while the sound design makes a phone call across decades feel like the most dangerous thing on screen. You finish knowing the story is incomplete, but that's the point: some connections survive incompleteness better than they survive explanation.

Made as a promotional ONA for the Japanese phone company KDDI au, this three-episode short was created to advertise the company's new research lab, au Mirai Kenkyuujo. The story is set in the KDDI R&D laboratory, where a team of scientists is working on a telephone capable of placing calls to the future. While they are using the device, something goes wrong, and an incident unfolds. It is a brief sci-fi piece built around that experimental phone.
