The series follows the adventures of a 14-year-old girl named Rami Nana-Hikari, who dresses in a Playboy Bunny outfit and lives with her grandparents and has a pet dragon named Spot (Pochi in the Japanese versions). Her enemies include Dr. Pon Eho, a tanuki Mad Scientist with an IQ of 1400 that stole Rami's sphere from her, and Himiko Yamatai, who first appeared in the second game, a princess who claims the spheres belong to her family. She also pilots a robot named Psy-vee.
This series uses the following tropes:
- Ambiguous Gender: Due to translator antics Spot is male in Japan and female in the translation. Now you'd think they would just be canonically male then, especially since at some points you can see Spot's testicles... But then they give birth to children in the first game's ending.
- Ancient Astronauts: Rami is actually a descendant of aliens who visited the earth long ago.
- Attack Drone: Rami can get baby dragon options in the first game.
- Big Damn Heroes: Himiko rescues Rami at the end of the second game.
- By the Power of Grayskull!: Rami's transformation phrase is "Hyper Cutie Bunny Change!"
- Demoted to Extra: Zigzagged with Spot in the second game. On one hand Spot mostly appears to serve only as a checkpoint, but then there are still some levels where you ride them.
- The Flatwoods Monster: The Flatwoods Monster is the boss of Chapter 5, Scene 1: Outer Space in Keio Flying Squadron 2. At first, rather than a skirt its lower half consists of a bomb-shaped rocket launcher. When dealt enough damage, it bursts open and sexy legs sprout from it. The Flatwoods Monster then tries to hit Rami with huge mace-hands.
- Laughably Evil: Both Dr. Pon and Himiko.
- MacGuffin: The key to the mystery treasure in the first game, and the spheres in the second.
- Ms. Fanservice: Rami. Playboy Bunny outfit? Check. Nice legs? Check. The only thing Rami doesn't have is big breasts, but even then she gets those briefly at one point.
- "On the Next Episode of..." Catch-Phrase: Every stage in the series ends with a preview of the next stage, followed by Rami saying, "Push start!" However, in the case of the second game, the game will automatically take you to the next stage.
- Thanking the Viewer: Rami at the end of the first game. She simply waves at the player at the end of the second game.
- Victoria's Secret Compartment: Rami at the end the second game stores some gold bars in this way. Funnily enough they give her Fake Boobs while she stores them.
- Villainous Crush: It is heavily implied that Dr. Pon has a big crush on Rami.
- Womb Level: The setting of the Final Boss battle of the second game is in the belly of a demon named Apocalypse.
