Steins;Gate

Steins;Gate is set in the summer of 2010, approximately one year after the events that took place in Chaos;Head, in Akihabara.

Steins;Gate is about a group of friends who have customized their microwave into a device that can send emails to the past (known as D-mails). As they perform different experiments, an organization named SERN, who has been doing their own research on time travel, tracks them down and now the characters have to find a way to avoid being captured by them.
