Self-styled Kogal queen Kotobuki Ran and her friends just wanna have fun, which includes shopping, hanging out, and scamming meals off gullible guys. Unfortunately, their 'hood' — Shibuya — is in constant danger of being despoiled by dirty old men, street gangs, nasty Kogal rivals, and other societal evils. But with a little help from her friends and a toughness born of coming from a family full of cops, Ran takes on the bad guys (and gals) with gusto!
Normal high school student Riku comes back home one day to find...she is now the school chairman of a famous elite school?! It seems her grandfather left her the post after his death and although Riku is not really enthusiastic about the idea, there happen to be two really interesting guys that attend that same school...
Sumi is in love with Mitsuru, but he doesn't seem to be interested in her as a woman. Determined to look more sexy and mature, Sumi takes an experimental growth hormone that her scientist father has been developing.
However, the medicine backfires. Instead of changing into a buxom femme fatale, Sumi changes into a beautiful young man! She--he--is so gorgeous and so cool that even Mitsuru begins to take notice. Although the new situation with Mitsuru is imperfect, Sumi discovers that she can be closer to her crush: they can talk man-to-man. Yet, being Mitsuru's friend also has a downside, particularly when he reveals that he is in love with a girl in his grade!
