Truly, this is why I love manga- you can have a series with a title like this, but it can turn out to be something deeply affecting, provided you can be persuaded to pick it up. There are no haughty airs or pretensions, but also no limits in the sense of subject matter or having to pander to secure a particular audience. Together these factors constitute a healthy background for any genre of literature.
The story concerns alienation, but it's far twisted from The Catcher in the Rye (go ahead, plays on the name are practically invited), to which it occasionally refers and its ilk. Early on the parody elements (Death Note, Code Geass, Detective Conan, etc.- again, feel free to play on the names; a scanlator went with Fap Note at one point) suggest this might go on as a somewhat disturbing ecchi comedy, but the moment the protagonist (hitherto an observer whose daring is confined to a single forbidden cubicle) feels a spark of sympathy and decides to act true to said confines his life revolves around, a different course is set. We follow from here on a malicious bargain that gets out of hand when the protagonist finds himself drawn in by true passion for the first time in his life, while his interlocutor, the object of his earlier sympathy, seems to further recede into a shell as she is 'empowered' to make him do her bidding on pain of exposure. It is this bargain and the budding friendships and romantic relationships in its backdrop that it ultimately threatens that provide the core tension of the story.
The title derives from an unexpected stand that broadens the narrative's scope and focuses on the nature of atonement, of setting an example at an unknown cost to oneself. The climax-free authenticity of events hereafter is something like you would find in a Haruki Murakami story (I was also reminded of Toradora as I read this, although that lacks both the stakes and the malice of Kurosawa). Trust can be a difficult thing to regain, but sometimes motivations resonate and the gravity of an act from which one gains nothing speaks to us. The bludgeon to alienation is really coming to know other minds under, not the worst-case assumptions, but those that seem true to us. The protagonist also learns that intensity is not all there is to a feeling and should not be what one must fear the loss of; returns may diminish, but the opportunity to connect and to feel ought to be seen as worth something in itself. This most fascinating part proceeds episodically- not quite hurried, but I feel some expansion might have helped.
I've kept the above free of specific spoilers by speaking as generally as I could, but I think it gets at the message the author is trying to convey. Curiously, I was thinking about the relative strengths of the social and sexual stimuli (the intellectual, being reason for its own sake, lags far behind) in humans shortly before I found this. The social stimulus very often overwhelms the sexual, and I suppose this story's claim to authenticity hinges on this hypothesis; it's the reason this isn't just a moralising tale about not being anti-social or a chronic self-abuser or what not.
There's a short story epilogue to this which confirms for me another important fact of life- always go for the tsundere.
The comedic potential of the series may be somewhat underused once things get going (towards the end of the first volume), so I propose an anime adaptation, which can then be made into an abridged series on Youtube to the inappropriate amusement of all.
