History Manga / NatsuENoTobira

A collaboration between Creator/ToeiAnimation and a then-very new studio called Creator/{{Madhouse}}, the 1981 film version features an all-star crew list of pre-anime boom creative talent. The evocative, theatrical musical score is courtesy of the late, great Kentarō Haneda (''Anime/{{Macross}}'', ''Anime/SpaceAdventureCobra'', ''Manga/BarefootGen''), while prominent TV anime screenwriter Masaki Tsuji (''Manga/TigerMask'', ''Manga/UruseiYatsura'', ''Manga/KimbaTheWhiteLion'') contributes a delicate, sensitive script that practically drips with drama. The film is co-directed by two other Tezuka-era veterans, Mori Masaki and Toshio Hirata. The cast was also top notch for the time, led by Creator/YuuMizushima as Marion and including actors like Creator/TohruFuruya, Creator/ToshioFurukawa, Creator/YujiMitsuya, Creator/KeikoHan...

* AnguishedDeclarationofLove: [[spoiler: Claude confesses his love to Marion this way.]]

* UnrequitedTragicMaiden: Both Ledania [[spoiler: and [[RareMaleExample Claude]]]] are this to Marion, and both are hit with tragedy. [[spoiler: Ledania kinda finds happiness again with Jacques in the manga, but Claude commits suicide.]]

* IntimateHealing: [[spoiler: When Marion is feverish in Sara's bedroom, she convinces him to go back to bed and strips nude to give him body heat. [[AManIsNotAVirgin It leads to more rather soon]].]]

* FourPhilosophyEnsemble: Before the plot begins moving [[FromBadtoWorse and the world goes to Hell for them]], Marion and his three friends fit in very well. Marion is The Cynic (snarky, skeptical, book smart, has quite the diregard for social rules if needed, is proud of being "rational"), Jacques is The Optimist (HotBlooded, emotional, stubborn, fierce), Lind is The Realist (calm, keeps the more emotional Jacques in check, rarely drops his facade) and Claude is The Apathetic (mysterious, quiet, not very eager to get into drama). [[spoiler: But in reality, both Marion and Claude turns out to have elements of The Conflicted, as both young men end up learning ''very'' painfully that LoveHurts and, when Claude commits suicide, Marion says they were NotSoDifferent]]

* YourCheatingHeart: [[spoiler: Sara is the wife of a very rich Count, and keeps the much younger Marion as her lover to fill the emptiness in her heart. The Count [[MyGirlIsASlut doesn't seem too bothered]], even giving her what can be seen as a ''compliment''.]]

* LightFeminineAndDarkFeminine: [[https://imgur.com/a/pFcQm Ledania]] is the Light, as a shy WomanInWhite with gentle and quiet behavior plus blond hair; [[http://imgur.com/a/v2oWF Sara]] is the Dark as an older and sex-aware adult woman with RavenHairIvorySkin looks. The story has them as {{foil}}s: the chaste-looking Ledania is [[NeutralFemale a symbol of passive innocence]] who can only watch as [[BreakTheCutie everything goes to Hell]], while the sensual Sara is more of an "adult lover" and TheTease [[KnightOfCerebus who dramatically "moves" the plot as she appears]]. Plus they have romantic ties to Marion, but [[spoiler: Ledania has her LoveConfession rejected by him]] whereas [[spoiler: Sara takes his virginity and keeps him as her lover for some time.]]

Lind transfers to a school in Paris, and Sara and her husband the Count also go there.

* BreakTheCutie: Four handsome teenage boys. A beautiful young girl. All of them get shattered in one way or another, [[spoiler: with fatal conequences for one of them, and near fatal to the others.]]

In the France of the late 19th century, Marion Fiese is a young schoolboy who prides himself on his adherence to a philosophy he calls "rationalism". Because of his disdain for emotional display, he ignores anything remotely akin to affection. But when he's entangled in a romantic affair with an older courtesan, Sara, his rationalism is revealed to be little more than a cover for his own emotional immaturity. Learning to love, Marion blossoms under his older lover's care but unfortunately, Marion has yet to learn the true price of the affair. At the same time, Marion's friends (Jacques, Linds and Claude) and Ledania, the prettiest girl in town, have their own love problems...
