History Characters / RootDoubleBeforeCrimeAfterDays

* InnocentlyInsensitive: An unfortunate flaw of Natsuhiko. As a result of closing off himself from everyone [[spoiler:since Yuuri's death]], he often falls into this. Most notable examples include [[spoiler:stating his discomfort about having his mind read despite the fact that Mashiro secretly hides her empathy ability so not to alienate him from her and his distrust towards Salyu for apparently hiding things when she is just NotGoodWithPeople]]. To be fair, he ''does'' regret his insensitivity and apologizes for it when he learns the full truth.

* NotGoodWithPeople: [[spoiler:As a result of a defect in her brain from the constant experiments in LABO, she has trouble reading moods and nuances which results in this. She warms considerably around Tenkawa family, but the rest...not so much.]]

* UnwantedHarem: A PlayedForLaughs case. [[spoiler:By the True Ending, Mashiro, Yuuri, ''and'' Salyu all harbor romantic feelings for him. Although the end of Root B has him having BigDamnKiss with Mashiro and seemingly chose her in the end, Salyu's LoveConfession to him basically has him responding that [[LoveYouAndEverybody he loves all three]], prompting her to beat him senseless. How their relationship progresses afterwards is ambiguous.]]

* DesperatelySeekingAPurposeInLife: [[spoiler:Was like this as a kid. He finally found his calling in inheriting Wataru's dream of becoming a rescue worker.]]

* AnAxeToGrind: [[spoiler:Uses an axe to kill Watase (and possibly others) in some √A bad endings.]]

* ThouShaltNotKill: Ukita is a staunch pacifist. [[spoiler:Even his terroist plot is tailored to ensure there's no casualities, and he's horrified when things go wrong. When Ukita's mental N claims his murderous rampage is a natural extension of his personality, Natsuhiko points out that Ukita would ''never'' kill without her manipulations, which she [[KnowWhenToFoldThem admits]].]]

* NeverHurtAnInnocent: [[spoiler:Even insane with malice, Kazami never hurts anyone other than Watase and Ukita, the two terroists responsible for LABO's condition.]]

[[caption-width-right:200:A perfectionist and a honest researcher]]

* ShipperOnDeck: She ships Natsuhiko and Mashiro despite her own feelings towards him.

* StrongFamilyResemblance: To the point where Natsuhiko looks like a male version of her.

* NiceJobBreakingItHero: At least twice.

* DidYouThinkICouldntFeel: She's gutted when Natsuhiko scolds her for not caring about Mashiro when she's actually just bad at showing it. [[spoiler:When she confesses just how bad she is with people, Natsuhiko apologizes.]]

* PsychicPowers: She is stated to be a communicator but her aptitude as one is low. [[spoiler:Her aptitude eventually goes to up to S-Rank as a result of being exposed to the WX particles.]]

* HeKnowsTooMuch: [[spoiler:For a while before the game began, Ukita was put under surveillance and was constantly followed by unfamiliar cars as a result of digging too much into LABO and Rokumei City's dark secrets. The "accident" he got involved in days before the LABO incident took place was actually engineered to throw his pursuers off the track by making it look like he was also targeted by Q.]]
* KilledOffForReal: [[spoiler:Died by a falling debris in √A Normal Ending after previously killing Jun, Ena, and Kazami.]]

* KilledOffForReal: [[spoiler:√A Normal End, courtesy of Ukita.]]
* ObfuscatingStupidity: [[spoiler:As it turns out, her hysterical behavior in the beginning of √A is just an act. She knows far more about the situation in LABO than she lets on.]]

* LikeBrotherAndSister: With Natsuhiko and Mashiro, even more so due to the fact that Miyoko more or less adopted her. [[spoiler:However, by the True End, she confessed having fallen in love with Natsuhiko, although whether it will go anywhere or not remains to be seen.]]

* AccidentalMurder: [[spoiler:Killed Salyu unintentionally in self-defense in √A Normal End. Combined with having failed to save Ena and Natsuhiko, he straight up crossed DespairEventHorizon after this.]]

* KilledOffForReal: [[spoiler:In √A Normal End, due to the amnesiac Watase arriving too late to save him.]]

* TookALevelInBadass: More like ''three'' levels in span of one week. In the beginning, Natsuhiko cannot even use telepathy despite his Rank S aptitude no matter how hard he tries. By the ending, [[spoiler:not only has he mastered Senses Sympathy, he also ultimately managed to resist and defeat the malice from a natural Rank-S communicator several levels above him.]]

* TraumaInducedAmnesia: [[spoiler:He lost his memory of the fact that Yuuri had died 9 years ago after the LABO fire, although as it turned out later in √D, his memory was actually [[LaserGuidedAmnesia intentionally erased by Yuuri]], who was alive all along as test subject of LABO.]]

* TheExtremistWasRight: [[spoiler:Although his and Watase's terrorism plot had not gone as intended thanks to the deaths that occurred, in the True Ending it was also their actions that ultimately became trigger for a more moral BC experiment after the LABO incident.]]

* ObfuscatingStupidity: [[spoiler:As it turns out, her hysteric behavior in the beginning of √A is just an act. She knows far more about the situation in LABO than she lets on.]]

* CoolBigSis: Flasbacks to her past shows that she was this for Jun [[spoiler:as well as her actual little sister Nagisa.]]

* PsychicPowers: She is stated to be a communicator but her aptitude as one is low. [[spoiler:Her aptitude eventually goes to up to S-Rank as a result for being exposed to the WX particles.]]

* GenkiGirl: Upbeat, even when she's trapped in burning nuclear facility undergoing a meltdown.

* BrainyBrunette: Has dark hair and is one of the leading physicist in her field.
* LoveMartyr: [[spoiler:She throws her life into work all for the sake of finding cure for Communicators' short lifespan (and especially her own son, who probably won't live past 30s as a Rank S Communicator), and as such she seems to accept the fact that Natsuhiko resents her for not being there for him.]]

* PosthumousCharacter: While fragments of her appear in the minds of people she’s corrupted, her own body is (mostly) dead when Watase’s group come across her.

* TragicMonster: It was not Nagisa's fault that she turned into N-ified Communicator with nothing but instinct to spread malice, but she cannot and will not stop, her presence had to be purged from the malice-filled memories of her victims.

* RapunzelHair: As a child before she became Subject N, she has very long braided hair that goes past her waist.

* AdjustingYourGlasses: One of his poses, which is present in his child version and current sprites.

!!! VA: Akane Tomonaga

* GoOutWithASmile: Her final fragment shows her smiling as she disappears from her sister's psyche.

* {{Adorkable}}: The Xtend episodes of hers and Watase's reveal that for all of her professional and cold front during work, she pretty much acted like a flustered schoolgirl when she realized that she is in love with Watase and makes several attempts to get close to her, culminating in her confessing out loud ''in the middle of physical training'' after Watase chewed her out for getting distracted and nearly got herself run over by a car.

* ReverseMole: [[spoiler:She is not actually a teacher; rather, she is a commissioner from ESP Bureau investigating the secrets of LABO along with Kuroda and Higa.]]

* AmnesiacHero: Wakes up in √A with no recollection of who or where he is. [[spoiler:√B reveals Natsuhiko, in act of self-defense, destroyed Watase's memories.]]

* {{Determinator}}: In √A, he ''will'' save everyone regardless of his own condition. On a less positive note, [[spoiler:he is also determined to fulfill his duty as a member of "Q", to the point he won't back down on his wager to take Yuuri into their custody.]]
* FantasticRacism: [[spoiler:Very slight variation towards Communicators, as the idea of having his mind read made him uncomfortable, though he saw the practical applications of BC and was otherwise perfectly civil with them. However, it was this slight apprehension that allowed Nagisa to warp his heart and memories to turn him into an AxCrazy man with severe bloodlust for Communicators.]]

* WorkingWithTheEx: He and Kazami were previously dating before they broke up sometime prior the start of the story.

* {{Adorkable}}: Very much so in the Xtend episodes.

* UndyingLoyalty: It's in her Enneagram type. [[spoiler:Her SanitySlippage is likely a twisted version of this, since she is so hellbent on killing Watase in order to preserve his good name and so the public will know him as someone who dies as hero instead of terrorist.]]

* LikeBrotherAndSister: With Natsuhiko and Mashiro, even more so due to the fact that Miyoko more or less adopted her.

!!Subject A / Alice Enflamme

A French woman and the first S-Rank Communicator found in the world. She was invited to Rokumei City to escape persecution in her hometown, but she was eventually N-ified and caused the Great Rokumei City Arson. She was then confined in LABO, where she died a year afterwards.

Watase's twin sister.

!!Subject N / Nagisa Tachibana
!!! VA: Shimizu Ai

A mysterious white-haired girl who appears dead in front of the cargo lift in Area 6. She is Kazami Tachibana's younger sister, whose death was faked nine years ago so that she could be taken to LABO for experimentation. After reading 351 people's minds, she became N-ified and lost her individuality, turning her into little more than an incarnation of pure malice.
