Paranoia Agent

Paranoia Agent (妄想代理人 Mousou Dairinin) is a Japanese anime television series created by director Satoshi Kon and produced by Madhouse about a social phenomenon in Musashino, Tokyo caused by a juvenile serial assailant named Lil' Slugger (the English equivalent to Shōnen Bat, which translates to "Bat Boy"). The plot relays between a large cast of people affected in some way by the phenomenon; usually Lil' Slugger's victims or the detectives assigned to apprehend him. As each character becomes the focus of the story, details are revealed about their secret lives and the truth about Lil' Slugger.

Enter Lil' Slugger

 * Prophetic Vision: To begin, a rabbit jumps behind the moon. What is it that the black rabbit sees on the horizon with his big red eyes? A fish on the land has trouble when he is stepped on by cows. The playful palace where the butterfly dances vanishes away. At twilight, the cows starts it by chance and the goodness continues. The golden fox grins at you. And Then…

Keiichi Ikari: (Singing in a sarcastic voice, to the tune of "Pop Goes the Weasel") "All around the mullberry bush, my partner chases a loony, I don't know what I'm doing here... Maniwa, what the heck are we doing here?"

Keiichi Ikari: "Maniwa? Maniwa? MA-NI-WA!!!"

No Entry
Misae Ikari: (To Lil' Slugger) I called you. I asked for you to come here. I admit I wanted a way out... but now I know that it was wrong.
