Awesome... Amazing... One... More... Eeeeeepisode !!!
Seriously I couldn't stop watching, the storyline is addictive, beware, you may end up watching 24 episodes back to back.
The story is about a 17 year old Japanese inventor, named Rintaro Okabe, who is one of my favorite characters ever written. He decided to start his own lab and recruit some lab members to create unique inventions. The funny part is that he pretends to be an evil mad scientist with mad laughter and the whole package :D
Some day they accidentaly invent a microwave oven that has the ability to send text messages back to the past, and as scientists, they start experimenting with it. But here comes the butterfly effect to ruin the day... Every message has some of the intented effects but it also has some sideffects that are not always minor. Of course when the past changes the world runs on a different timeline so the memories of every lab member is rewritten to match the current timeline events. Only Okabe remembers the events of the original timeline because of a special ability his mind posseses called "Reading Steiner", so he is the only one who can see the results of the changes he wanted to make, but also the sideffects.
As you may have guessed at some point the sideffects become too massive to ignore them and Okabe has to reverse all the changes he made to the timeline. Will he succeed, or will he succumb to the needs that made him change the timeline in the first place ?
P.S. The storyline is tottaly cool, but what really excels in this anime are the characters, especially the lab members that are all either exceptionally funny or spooky and mysterious, that combination of characters and storyline have elevated this anime in my top 3 completed anime series together with Death Note and Code Geass.
