Overview

ActionScience FictionMystery

Theatrical version of episode 5 of Ultraman Ace TV series. Two women go missing, with witnesses testifying that they vanished underground. The only common link between the incidents was that both women had type O blood. TAC closes the case, but when Yuko and Seiji are out shopping, Yuko herself is targeted. Seiji manages to free her, and the two catch a glimpse of the terrible-monster, Aribunta.

Standout Aspects

Practical Effects

Aribunta puppet has genuinely unsettling mandible design.

Costume

Yuko's civilian outfits scream late-70s fashion time capsule.

Stunts

Underground tunnel collapse sequence surprisingly ambitious for TV budget.

Best for:Binge: Marathon with other Ace episodes for full context.·Friends: Drinking game: sip every time TAC ignores obvious clues.·Rewatch: Spot every reused Ultra Brother stock footage shot.
Heads up:Violence: Women dragged underground screaming; monster impalement with Ultra Blade.

Deep Dive

Trivia, insights & behind the scenes

Trivia

This theatrical 'movie' is literally just episode 5 with a title card—1989 Japanese cinemas loved repackaging TV content for quick yen.

Insight

Aribunta's design homages 1954's Them!, but the blood type obsession reflects 1970s Japan's actual pseudoscientific personality blood type beliefs still prevalent today.
