----
!! Shuuen no Shiori Project contains examples of:
* AbandonedArea: The Music room in the OldSchoolBuilding A-ya, B-ko, C-ta, and D-ne always meet at for their occult talks.
** Slightly subverted with the Film Club kids as 10 years ago it was still a normal HighSchool.
* AlphabeticalThemeNaming
* AlternateUniverse: The second novel is just this with all of the Occult Club members switching around the urban legends they got before; A-ya gets the Monkey Paw; B-ko, Mearry-san; C-ta, Doppelganger; and D-ne, Hide and Seek Alone.
* AnyoneCanDie: [[spoiler:[[EverybodyDiesEnding And everyone does]].]]
* ArtifactOfDeath: The Book and Bookmark of Demise.
* BeCarefulWhatYouWishFor: [[spoiler: D-ne uses the wishes of the Monkey's Paw to become B-ko and to escape from her impending misfortune. Unfortunately, this backfires as becoming B-ko causes all of B-ko's misfortune to befall on her, also getting her killed by an impostor in the end.]]
* BreakingTheFourthWall: The Occult Club does just this at the end of the second novel. [[spoiler:The traitor [[YouBastard was you all along!]]...[[UnseenAudience or is it?]]]]
* ChekhovsNews: In B-ko's song, Warning of Imposters, the beginning is a tv forecast calling a chance of imposters in the area. [[spoiler: it ends up being her imposter.]]
* ColourCodedForYourConvenience: A is red, B is purple, C is some variant of green, D is some kind of blue, and [[OddNameOut E is yellow.]]
* CreepyDoll: D-ne's Ririka doll.
** A-ya's bunny doll counts as this too.
* DysfunctionJunction: A-ya is a [[LonersAreFreaks loner]], an occult freak, and [[ManipulativeBastard quite frankly]], a [[{{Jerkass}} jerk]], B-ko, while [[TheAce seemingly perfect]], is actually a {{Mood Swinger}} {{Tsundere}} that's constantly worried about her image, and both C-ta and D-ne are {{Stepford Smiler}} [[StalkerWithACrush stalkers]] who are [[CrazyJealousGuy way]] [[ClingyJealousGirl too]] [[{{Yandere}} obsessed]] with the former two. And these guys are supposed to be [[AntiHero our protagonists]].
* DwindlingParty: [[spoiler: Every character dies at the end of their chapters, until the entire cast has died.]]
* ExactTimeToFailure: If you do not fulfill Kokkuri-san's demands by one week, you'll die.
* ExactlyWhatItSaysOnTheTin: It's a bookmark. And it kills people.
* EvilPhone: C-ta has a case of this with Mearry-san.
** [[TechnologyMarchesOn Apparently it can use]] Website/{{Twitter}} as well; [[LiteralMetaphor being "followed" now sounds so much more ominous...]]
* {{Foreshadowing}}: The smell of D-ne’s shampoo really sticks around.
** B-ko mentions Mearry-san in their discussion about who’s watching A-ya.
* IronicEcho: “I will protect you.”
* LoveConfession: [[spoiler:D-ne to B-ko.]]
* LoveDodecahedron: D-ne is in love with B-ko, who's in love with A-ya, who either loves rumors or C-ta or maybe just [[ChasteHero doesn't care about love]]. C-ta, as much as he'd deny it, is obviously in love with A-ya too, and he also has a lot of moments with D-ne.
* MadnessMantra: “WHY WON’T YOU COME OUT WHY WON’T YOU COME OUT…”
** “No no no no no no no no no no no that’s wrong”
** It's been said you can't have a Shuuen no Shiori novel/manga chapter without a page of words repeating over and over.
* MediumAwareness: A-ya displays instances of this especially in the second novel.
* [[spoiler:MetaTwist: Invoked]] at the end of the second novel. [[spoiler: This is a Shuuen no Shiori novel. What do you mean, everyone's going to live?]]
* MurderIsTheBestSolution: They must kill the traitor in order to end the game.
* NoNameGiven: All we know is that their names might end in a particular syllable.
** [[spoiler:A-ya's classmate who gets sliced in half and D-ne's classmate who ends up hanging off the building don't even get that much.]]
* NiceJobBreakingItHero: The incident from ten years ago that started the rumours of the Book of Demise was [[spoiler:caused by the Film Club trying to make a movie.]]
* OneLetterName: This would have been literal, had Suzumu not decided calling them by only one letter would sound weird.
* RashomonStyle: Each arc of the novels and the manga focuses on each character's POV of the demise game and how they tried to handle the situation.
* StalkerWithACrush:While only D-ne’s crush has ever been explicitly stated in canon, [[spoiler:C-ta has four cameras in A-ya’s room and a microphone in his bag.]]
** He’s just doing that because he’s A-ya’s [[{{Yandere}} ‘’one and only best friend.’’]]
* TrueCompanions: Yes, really. They're ultimately depicted as such in the song ''Shuuen no Shiori''.
* UnmovingPlaid: In some of the music videos, the main characters' school uniforms' skirts/pants are depicted as such.
* {{Yandere}}: There are two, and there are only four main characters. OhCrap.
