I don’t think I’ve ever seen an anime that managed to hook me so hard and so quickly that I ended up watching every single episode in a single night. By the time morning had come, the lack of sleep was not the only reason I was twitching at every shadow and couldn’t stand to look at anything pink for at least a week.

The series is now over five years old, but still does a terrific job of making its viewers feel worried, tense and paranoid. Imagine the anticipation one experiences just before the killer jumps out in a scary movie. Yes, that. Paranoia Agent manages to capture it, bottle it and use it on you almost at will.

Paranoia Agent first aired on Japan’s WOWOW between February 2, 2004 and May 18, 2004. While at first glance, the series seems to be composed of little more than a group of disconnected vignettes all losely tied together by the existence of Lil Slugger (Shonen Bat aka Bat Boy in the original Japanese). Lil Slugger is a grinning kid wearing shorts, gold colored inline skates, a red baseball hat and wielding a slightly-bent, golden baseball bat. His grinning features are almost always kept in shadow, preventing anyone from getting a good look at him. At first, each episode does seem to stand alone, but as you get deeper into the series mythos, one begins to realize that the individual episodes are parts of a grander design, like a puzzle being put together, and the picture becomes clearer and clearer with every episode.

The creator, Satoshi Kon, admitted that the series was primarily created to incorporate the wealth of ideas and stories that he hadn’t ended up using during his previous films. Like those previous films (which includes Millenium Actress and Perfect Blue), this show is by turns deeply psychological, surreal and sweetly funny. There are moments of pure inspired insanity, where the landscape is shaped by the psychosis of the cast… playing against moments of slow, mounting psychological terror as the perfectly innocent and normal gets turned on its head and becomes a source of pure nightmare.

Despite how broad a sweep the stories encompass, it all ties together. Ranging from the tale of a corrupt policeman who has to turn to robbery to keep up with his payments to the Mafia, to the meeting participants in an internet-based suicide pact (who keep failing), gossiping housewives telling stories within the story, to the travails of an animation studio trying to get their anime in on time while being picked off one after the other.

All of this contributes to the greater whole of the world that Lil Slugger exists in. Everyone is broken in one way or another, either to begin with, or over the course of the series. The series opens as it closes. The scenes echoing each other implying that despite how profound the changes the occur during the series the world carries on.

This is a rare sort of series where it would be possible to watch the earlier episodes on their own and still come away with a satisfying experience, but for best results, one should watch Paranoia Agent from beginning to end.
