Manga / Kanojo no Kagi wo Akeru Houhou

Go To

A series by Yumi Nakata, with her typical focus on underwear. Or rather, not wearing underwear.

Haruma's first impression of Chitose would be striped panties. Running into her in the hallway, Chitose's panties greet Haruma before they even know each other.

Immediately, Haruma finds himself attracted to this mysterious striped pantied girl, only to discover that she is transferring into his class AND she is going to be the housekeeper at the apartment complex his Grandfather owns — due in no small part to his grandfather buying up her debt (leaving her in indentured servitude to the apartment complex until she pays it off).

Thus starts Haruma and Chitose's growing relationship, which is hampered only slightly by the fact that Chitose is a raging exhibitionist, barely able to keep her panties on for any significant length of time. Er, what?


Let the skirt flying romance comedy begin!

KnK provides examples of:

  • Accidental Pervert: Chitose, in a rare female example. Part of it is caused by her tendency to lose her underwear, and her mild tendency towards exhibitionism.
  • A Date with Rosie Palms: Chitose during the "climax" of Chapter 1. Her thought bubbles afterwards suggests the odd circumstances leading to this are a regular occurrence for her.
  • Bookends: The first chapter begins and ends with Haruma making a joke about Chitose's name.
    Haruma: If you pair the words 'Striped Panties' with 'Transfer Student', it becomes Hayamine Chitose.
    Haruma: ... If you take off 'Striped Panties' from 'Transfer Student', it becomes Hayamine Chitose.
  • Cute Clumsy Girl: Chitose, played completely straight. If she ever walks or runs away, a chibi version of her will be seen falling down in the next panel.

  • Gag Boobs: The class rep. Her gainaxing is overstated as a gag during the maid uniform chapter.
  • Going Commando: Chitose, constantly. She's even holding her panties on the cover of the manga.
  • Hadaka Apron: In Chapter 7, Chitose sees her lookalike wearing hadaka apron in the ero-magazine Haruma obtained. This inspires her to try it herself, since she was alone while Haruma was out shopping. Which is exactly when Haruma comes back. Before anything can come of it, Sayuri visits.
  • In Vino Veritas: During her welcoming (drinking) party, the sight of the class rep getting drunk and being teased by Sayuri... or rather the site of Haruma drooling over it... causes Chitose to take her panties off and place them on Haruma's head.
  • Meet Cute: The first shot of the story. Haruma runs into Chitose, getting a glance of Chitose's striped panties. She reacts poorly, but not for the obvious reason.
  • Meido: The class rep in chapter 6, made all the more fanservicey because she is very obviously not wearing a bra. Chitose follows suit.
  • Ms. Fanservice: Sayuri, who is a stripper by night. She walks around in the most sexual underwear she can during the day, because "it's her uniform." And because this is a Yumi Nakata manga.
  • Not What It Looks Like: The class rep falls onto Haruma, giving him some inadvertent Marshmallow Hell, which sends Chitose into the Corner of Woe.
  • Potty Emergency: Played With in Chapter 5. Chitose tells Haruma this is about to happen to her as a ploy to get out of the room they were locked into by Those Two Guys. Haruma suggests various solutions (a discarded bottle, an empty plastic container), but Chitose rejects them and runs away... falling down in the process and causing her to have the beginnings of a Potty Failure.
  • Reluctant Fanservice Girl: Chitose combines this with her exhibitionism to weird effect. She's constantly humiliated by the situations she finds herself in, especially in front of Haruma, but at the same time enjoys them on some level. Fortunately for her she's also a Tsundere, so personal epiphanies need not apply.
  • Right Behind Me: While practicing a pose in Hadaka Apron in Haruma's house, Chitose imagines the jawdropping look of shock he'd have if he walked in and saw her. Then she turns around and the jawdrop the very real Haruma is sporting is even bigger.
  • Shameless Fanservice Girl: Sayuri doesn't wear clothing, instead wearing the most elaborate underwear she can. She justifies this by saying she's a stripper and it's her uniform. (Haruma isn't buying it.)
  • Tsundere: Chitose to Haruma, partially because of the embarrassment her condition causes her (which Haruma keeps ending up involved in, one way or another).
