History Fanfic / ACertainUnknownLevel0

* ItsNotYouItsMe: Discussed, Touma notes that his misfortune would be a contributing factor in relationship problems between him and whoever he did decide to get into a relationship with, this matter being more problematic due to Touma's GrandTheftMe beliefs. Misaka tries to say that anyone who loved Touma would be able to up with it but is taken aback when she realizes that a brief argument makes her realize that [[RealityEnsues no matter how much one loves someone, their patience does have limits and those would be pulled to their extreme]] with Touma's [[BornUnlucky supernatural bad luck]].

* RealityEnsues: Lots of it.
** While Touma, the frog-faced doctor, and Yume's plan to get the nano machines without any [[spoiler: males]] was good, it is considered impossible for it to not touch any human hands. Thus how Kamui was able to get the special project inside the nanites without anybody realizing.
** Touma realizing he can't save everybody...but will still try unwavering in doing so.

* TakingTheHeat: To prevent Kuroko from being expelled for collateral damage, Touma opted to take the blame and punishment instead.

* TheAtoner: What Kongou Mitsuko becomes after the mission to rescue Touma from the coalition against the FIVE_Object Project Coalition.

* ScrewTheRulesIHaveConnections: Aaron Gracestone, Kisaragi Maeda and Damian F. Slivka were able to march into the female-only School Garden with an army of bodyguards unimpeded as part of their campaign against Kongou Airlines thanks to their respective comanies' influence in Academy City.

* EvilBrit: Aaron Gracestone of Circuits and Chips[[spoiler:, more so after his brainwashing at the hands of Kihara Kamui.]]

* EvilBrit: Aaron Gracestone[[spoiler:, more so after his brainwashing at the hands of Kihara Kamui.]]

* EvilBrit: Aaron Gracestone[[spoiler:, more so after his possession by Kihara Kamui.]]

* MarryThemAll: Deconstructed by Uiharu, who actually considered it until she realized that humans and love are inherently selfish by nature and all this trope would do is cause the girls to jealously wait their turn for Touma, all the while Touma would be passed around like some shared object with no on really being cemented as his true love.

''[[https://www.fanfiction.net/s/8918264/1/A-Certain-Unknown-Level-0 A Certain Unknown Level 0]]'' is LightNovel/ACertainMagicalIndex fanfic written by [=MrQuestionMark=] that builds upon the UrbanLegend of the certain unknown level 0 that defeated Accelerator and the Railgun.

* AwLookTheyReallyDoLoveEachOther: While not love per say, Faith has more care to Orion than she lets on. Aiding him when he's injured, and shows rage when [[spoiler: Misaki]] shoots him using her body. Asking Orion who did it, implying she would have killed [[spoiler: Misaki]] given the chance.

* UnwinnableByDesign: A non-video game example in chapter 152 lies in the Magic Name system used by Western magicians. Unlike what Styl says, a magician's Magic Name is not just some fancy words like LetsGetDangerous, but rather is in fact a way of life carved into their very ''souls'' making it almost a like a {{Geis}}. The problem is that most of them are lofty goals that can never be accomplished, even by Saints, unless one is a Magic God. [[spoiler: By declaring herself [=Salvare001=] "Be the Salvation of Those who Cannot be Saved", Otohime has basically condemned herself to the same ChronicHeroSyndrome as her cousin.]]

* RealityEnsures: Lots of it.

* HairDecorations: Uiharu and her flower headband.

* ColdBloodedTorture: The things done to Touma by Kirihara Kamui in Aaron Gracestone's body are enough to sicken even the author and only serve to show how much of a monster Kamui is even among the Kiriharas.

* ForTheEvulz: Kirihara Kamui does thing in a unethical manner not because he feels it limits science, but simply because he can, showing that unlike the apathetic sociopathy of the rest of the Kiriharas, Kamui is instead a sadistic psychotic monster who does things just because he can.

* OverdrawnAtTheBloodBank: lampshaded by Kirihara Kamui, who is impressed by just how much blood Touma had lost during his torture of the latter and is still alive despite of that.

* DarkerAndEdgier: The U////////iharu Kazari arc might just be the darkest story arc to date.
