Paranoia Agent - Season 1 (2004)

After the strings of attacks by Lil' Slugger, it is discovered that each victim has some sort of relationship with previous victims. Meanwhile, the life of Masami Hirukawa, a police officer, is about to be changed forever.

Ikari and Maniwa interrogate Lil' Slugger who turns out to be in the eighth grade. Still, he admits to the attacks. However, he confuses reality and believes that the world around him is a medieval-style role-playing game.

Ikari and Maniwa find the old homeless woman while a hurricane is about to make landfall. There, they discover something from the old woman that turns the entire case around. Meanwhile, a girl named Taeko is reminiscing over her life.

Ikari and Maniwa receive word of Taeko's attack. Masami is devastated by Taeko's amnesia as Ikari pursues the investigation from another angle since it happened in a different district.

Three Internet buddies form a pact to meet and commit suicide together. But as these poor souls bungle their numerous kamikaze attempts, they become close to each other.

After hearing of the suicide pact, several women share rumors related to Lil' Slugger, most of which are far-fetched.

Maromi is getting her very own anime. However, the staff begins to fall behind as the deadline approaches. They get rough with Saruta Naoyki, the production manager who is unable to competently do his job.

Misae Ikari returns to her home to find Lil' Slugger waiting. Before she allows him to attack, she talks about the troubles in her life.

After a failed attempt at defeating Lil' Slugger, Maniwa turns to the old man for help.

A dark formless flow that Maniwa describes as Lil' Slugger starts to overrun Tokyo as a result of Maromi's disappearance.
