Twilight of the Cockroaches (ゴキブリたちの黄昏, Gokiburi-tachi no Tasogare) is a 1987 Japanese fantasy drama film written and directed by Hiroaki Yoshida that combines live-action footage with animation.

[2] In his New York Times review, Vincent Canby wrote: "The publicity material for Twilight of the Cockroaches describes the film as an allegory about the fate in store for affluent Japan if it doesn't meet its international responsibilities.

During the early-to-mid 1990s, the film was shown frequently on Turner Broadcasting stations such as TBS, TNT, and Cartoon Network, often paired with Vampire Hunter D and Robot Carnival.

They are led by a roach named Sage/Professor, who advises them on matters and states he negotiates with Saito on any issues.

One evening, Saito and Momoko notice each other from across the apartment complex and soon start seeing each other, though the Hosino roaches are unaware of her.

During one visit, Naomi inadvertently returns to Saito's apartment, having hidden in Momoko's purse after a horrific experience in a roach motel.

In addition, both Ichiro and Hans, knowing that the other loves Naomi, agree to settle things like men after the battle is over.

In response, Saito and Momoko resolve to kill all the roaches at once, setting off many bug bombs and spraying them all around the apartment.

Naomi tells Ichiro to escape and meet her at a nearby shrine (actually a toy abandoned in the apartment yard complex), where they will start a new life away from humans.

As they escape, Naomi is seemingly killed with insecticides and Ichiro, though he manages to begin flying, is gruesomely shot to death with an air rifle.

The epilogue shows her with a huge litter of children, all seemingly immune to insecticides.
