A kid walks into hell to save his friend with nothing but a magic doll and pure stubbornness. The world he finds there isn't designed to kill him, it's designed to confuse him, distract him, seduce him with wonder so he forgets why he came. That tension between the beautiful nightmare and the mission never breaks.

When Belt Satan, the demonic ruler of another world, kidnaps Paul's friend Nina, the young boy boldly sets out to bring her back. He is not alone: Pakkun, a plush doll gifted with magical powers, lends a hand as the pair dive into Belt Satan's dimension, a place where toys come to life. The road to Nina is full of hardships, yet Paul also comes across many charming marvels on the way. Across 50 episodes, this 1976 TV adventure pairs a daring rescue mission with a fantastical world of animated toys.
