this is possibly the cheesiest manga i've read in a long time. and that's saying something. but for some reason, despite the incredibly high levels of cheese (thank goodness i'm not lactose intolerant), i really like this series. it probably takes me about 30 minutes to run through an entire tankobon, so there's not really much in the way of a time commitment. and it's fluff, pure and simple, so there's not really much in the way of any sort of mental commitment either. and some days that's a good thing.
"high school debut" is the story of middle school jock haruna, who decides that when she enters high school she will put away the cleats in favour of high heels and try to make herself over to be more girly in order to get a boyfriend. needless to say haruna's natural inclinations lie more toward sweatpants and trainers, and her understanding of how to appear more feminine is culled from various teen girl magazines. try to imagine living your life based on rules laid out in "cosmo girl", "ym" and "seventeen". long story short; it's a complete disaster.
haruna decides she may need a little help with this goal, and decides to enlist the help of a coach, a "love coach". she chooses a cute upperclassman named yoh. she actually walks up to the guy and asks him to help train her to be more attractive. of course, no shock here, yoh looks at haruna like she's an alien, says "no", and walks away. this being a romantic high school manga though, yoh eventually changes his mind and agrees to coach haruna under one condition, she mustn't fall for him. well, we all know where this is going, right? right.
if you like fluffy manga in the spirit of "ouran high school host club" or "lovely complex" you might also get a kick out of "high school debut", just be sure to take your lactaid ahead of time.
