One morning, Nagase witnesses the moment his classmate, Tsubasa Amamiya, jumps in front of the oncoming train. He starts thinking about why she'd choose to die but arrives at no answer. Seeing this his friend Fukai hands him a capsule which he claims is a miniature time machine. Nagase, half-in-doubt, takes the capsule and wakes up 2 weeks in the past. He then meets Amamiya on the rooftop under the rain... First Prize winner of Kodansha Ranobe Bunko's 6th Rookie of the Year award​.

Danjo Nanji, Ishino Mika, and I, Akutsu Goro, are childhood friends and members of the Literature Club - and we have a little special power. It would be a stretch to call it a superpower, and not quite enough to call it magic, but that's about it. We call this power, which is like a bug in a game, a “glitch.” With this power, we aim to conquer the world. It may sound like a joke, but we are serious. Considering the circumstances we are in, we have to conquer the world in order to save it. (Source: Kodansha, translated)
