Амане Судзуха

A girl that really likes riding bicycles, and is quite energetic, though a little crude. If you stick around her, she's surprisingly cautious. Very helpful. A little too familiar with things, but doesn't dig too deep. Not quite comfortable with having other people help her. For that reason, she spends as little time as possible. Her personality drastically changes when it comes to her own interests. Proactive. Has a habit of using strange and difficult vocabulary at times, but somehow you can tell she's purposely doing so. Ended up hanging out with the Future Gadget Laboratory since she started working at the CRT TV Workshop.

It is revealed in Episode 14 that she came from the year 2036 to save the world from SERN's rule. Therefore, she used the name John Titor on Internet boards so that Okabe and the others would notice. She was the one who sent the time machine crashing into Akihabara in 2010, right when the Phone Microwave was being developed. This time machine, revealed to have been created by Daru, could only go back in time, but could never go to the future. In order to find the IBN 5100, Suzuha decides to go back to 1975 and then bring it to Okabe to stop SERN. In deciding so, she would have to leave 2010 and wouldn't be able to come back. Dedicated to her mission, she decides to go.
