In 1995, Kadokawa Shoten created a new manga called Yōkai Buster Ruka and they wanted Sting to reprogram and edit the Super NES game The Jetsons: Invasion of the Planet Pirates and turn it into a new game called Yōkai Buster: Ruka no Daibōken (妖怪バスター ルカの大冒険, lit. "Phantom Buster: Ruka's Big Adventure") with new music (composed by Mitsuhito Tanaka), new enemies and new areas. Both versions have essentially the same engine with a different story and theme. They also have a strict time limit that punishes tardiness with lost lives.
The player takes control of Ruka-chan, an aggressive demon girl who lives in a world filled with harmful monsters. Much of her past is shrouded in mystery and her age is deliberately hidden in context. She lives a long life but has the mentality of a 13-year-old girl. Compared to the futuristic setting of The Jetsons, the Japanese version uses a contemporary setting with Japanese architecture. Extra features were added into the Japanese version including an extra underwater level, a mini-game, and a training mode.
