History VisualNovel / KanaLittleSister

''Kana: Little Sister'' (Kana ~Imouto~) is a VisualNovel depicting the story of 15-year-old Kana, a girl who suffers from a chronic life-threatening disease and her older brother, Takamichi (Taka), who supports her and cares for her. The game deals with the relationship between both siblings, which gets more and more intense as time progresses. There is a clear incestuous element later, but which goes far beyond mere physical attraction.

** He later shows Kana how to play "Buyo Buyo", the popular puzzle game, at an arcade.

* DownerEnding: Most of the game's endings.
** Seeing as how [[spoiler:Cana's survival hinges upon getting an organ from Kana, all of them are downer endings.]]
*** And, at the same time, they're all {{bittersweet|Ending}}. To clarify, there is a GoldenEnding, [[spoiler:in which Kana survives but leaves Taka in order to get some real-world experience and independence (it's left ambiguous whether she plans to return to him)]], three [[ExactWords Intellectual Routes]], [[spoiler:in which Kana understands and accepts her death and parts "in good terms" with her brother]]; a Normal ending, [[spoiler:in which Kana doesn't accept her death but Taka manages to get over it and stay sane, implying a possible relationship with Yumi]], and a bad ending of sorts, [[spoiler:with Kana not accepting her death and dying sad and angry, and Taka becoming literally mad with sorrow, but eventually recovering and managing to rekindle a relationship with Yumi]].

%%* DeclarationOfProtection: Invoked by Taka early in the game.

* TheCaretaker: Taka the older brother looks after his little sister Kana.

* TropeMaker: Already being an example of this for a story about terminally ill girl, Kana at one time had a huge impact on BrotherSisterIncest plots, popularizing many tropes, including a [[LittleSisterHeroine imouto]] as the central romantic interest, scene of masturbation, catch the protagonist during his incest with his own sister and of course, [[spoiler:the discovery of the fact that the main character and his sister non blood related caused by desire to smooth out the overall of provocative tone of story]].

* ADateWithRosiePalms: Yumi admits to it. [[spoiler:Taka watches Kana do it, on some paths.]]

%%* IllGirl: Kana, Cana.

In 2015 Jast USA released an English version of the UpdatedRerelease ''Kana Okaeri'' (meaning ''Kana, Welcome Home!''), which contains full voice acting and [[HotterAndSexier animated sex scenes]]. The original is also available for half the price. There's also an "all-ages" version released for the PSP ([[NoExportForYou It's exclusive to Japan, unfortunately.]])
