The infamous Shounen Bat (Lil' Slugger) is terrorizing the residents of Musashino City. Flying around on his rollerblades and beating people down with a golden baseball bat, the assailant seems impossible to catch—much less understand. His first victim, the well-known yet timid character designer Tsukiko Sagi, is suspected of orchestrating the attacks. Believed only by her anthropomorphic pink stuffed animal, Maromi, Tsukiko is just one of Shounen Bat's many victims.

As Shounen Bat continues his relentless assault on the town, detectives Keiichi Ikari and Mitsuhiro Maniwa begin to investigate the identity of the attacker. However, more and more people fall victim to the notorious golden bat, and news of the assailant begins circulating around the town. Paranoia starts to set in as chilling rumors spread amongst adults and children alike.

Will the two detectives be able to unravel the truth behind Shounen Bat, or will the paranoia get to them first?

For those who aren't used to a Satoshi Kon anime, be prepared. They usually start off as a normal type of anime, and then take a serious turn for the surreal. As for Paranoia Agent, it starts off as a normal detective-style anime but then the plot twists and turns worse than a twist-tie on a bag of wonder bread. For those used to Satoshi Kon's work (Paprika, Tokyo Godfathers, etc), none of this is news. Personally I enjoy a good "whodunit" anime since I also love CSI, 24, Prison Break, etc. These kind of shows actually get the viewer to really think how read more

Story -
It is very hard to give a rating for Paranoia agent that can be surmised using the numbers rating system. The story is quite complicated but excecuted with flair. Any dull moments serve to advance the viewers understanding of the complicated characters and scenarios. Plainly the plot revolves around a series of attacks on people who appear to be unrelated. The plot dedicates episodes to each of these victims and merges their paths together to weave a story of connections and basically highlight the power of Paranoia. This is a gritty and mature anime, it deals with issues such read more

Paranoia Agent is very different from any of your average anime. It can also be pretty hard to keep track of, and there are some parts that are very... strange. The anime could also sometimes be trippy and disordered and also be labeled as creepy. In MY opinion I do not believe it was scary, but as a warning you should be prepared for creepy things.

If you ever watch Hell girl (Jigoku Shoujo) its something like that. There are a whole bunch of one shots but eventually they come together (sort of). A boy, Shounen bat in subtitles and lil slugger in dubbed, read more
