Anime Post: Steins;Gate
A show about a little group of odd balls, LARPing as resistance fighters against a sinister organization called... CERN.
Said group of odd balls consist of the "Mad scientist" Okabe, his young best friend who pretends to be his "hostage" named Mayuri, a rather crude humored computer nerd nicknamed Daru. They call themselves Future Gadgets Lab. They're soon joined by a girl named Kurisu, an American neuro-science researcher, who recently became interested in the possibility of time travel, and had her lecture disrupted by an attending, rowdy Okabe. They decide to focus on discovering time travel after encountering the Urban legend John Titor (look it up) in an online AMA (ask me anything) session. Somehow, Future Gadgets Lab pioneering attempt at time travel is accomplished using a microwave, a couple of cellphones, and a Banana. Of course they'll use it to mess with time. This is a time travel story, so why not. And of course the consequences are awful. Again, This is a time travel story. Who doesn't expect that to happen?
While they may not have known or expected it, Future Gadgets Lab temporal dalliances draws the attention of CERN, who turned out to be real and the sort of evil organization Okabe always pretended it was. The running theme at this point of the story and onward is pain. Since, Kurisu is more well read when it comes to time travel, she is able to help Okabe. Kurisu and Okabe get to know each other well enough that, even though she herself doesn't remember much through different timelines, she is able to help, so that Okabe isn't so helpless and alone in his maddening mission.
TL;DR: The Guy Who Texts Through Time, with more tragic results. Love Helps Break The Cycle.
This used to be a dating sim. I totally never played it though...
