'''WARNING: Spoilers ahead!'''


[[folder:Main Characters]]

!Takumi Nishijou
->'''Voiced by:''' Creator/HiroyukiYoshino (JP), Creator/ToddHaberkorn (EN)

The protagonist, a second-year student at Suimei Academy who barely visits school in the first place. He spends most of his time playing Empire Sweeper Online, in which he is the most famous and powerful player (known as [[SpellMyNameWithAnS Neidhart/Knighthart]]).
* ArtificialHuman: [[spoiler:Quite literally a figment of someone's imagination. In this case, that of the real Takumi Nishijou.]]
* CantStandThemCantLiveWithoutThem: His attitude towards "3-D" girls.
* ClassicalAntiHero: He has intense social anxiety, isn't very brave, doesn't want to get involved, is frequently unpleasant and is rather judgmental. He's apparently intelligent, but prefers to spend all his time on meaningless hobbies. Nevertheless, he's the hero that Shibuya needs.
* FakeMemories: [[spoiler:Specifically, his life from the age of maybe 12 or so until starting high school.]]
* FlawedPrototype
* HeroicBSOD: [[spoiler:He has two during the course of the story. The first is after chapter 6, when he thinks his sister is dead. The second is after the revelation that he's an ArtificialHuman.]]
* {{Hikikomori}}: Takumi spends most of his time in his own house (container on a roof). He does go to school once in a while, but he has managed to invent a chart which allows him to graduate with minimal attendance if he simply keeps following its schedule.
* InSeriesNickname: Has three of them: Takkii, Taku and Takumi-shan. They are used respectively by Seira, Rimi and Kozue.
* {{Jerkass}}: He's selfish, rude, self centered and has a lot of entitlement issues.
* MrImagination: Deconstructed. His detachment from reality goes up to the point where he could be diagnosed with schizophrenia.
* {{Otaku}}: Takumi, having no interest in real-life world, spends a lot of his time immersed in games, anime and manga. He also possesses a collection of figurines.
* ProperlyParanoid: Yep, turns out Yua really did have ulterior motives in getting close to him, as should be obvious.
* SplitPersonality: Takumi starts to think he had one that was responsible for the new gen killings. [[spoiler: He was completely wrong.]]
* SuperLoser: He's a rude, selfish hikikomori with the power to make delusions real. [[spoiler:Near the end he even embraces it and sneers at the adulation of the crowd after catching the killer. He's a loser through in through no matter how they want to look at him!]]
* ThisLoserIsYou: He seems to be the type that is written to be so pathetic so that anyone could feel superior to him.
* ThroughTheEyesOfMadness: He is a self-described disgusting, delusional, {{otaku}}, {{hikikomori}} who is approached by [[HaremGenre several beautiful girls]] all with a mysterious connection to a series of murders going on in Shibuya. This makes it extremely hard to tell where the events of the series lie on the line between paranoid hallucination and supernatural strangeness -- if there is in fact any separation between the two at all.
* TomatoInTheMirror: [[spoiler:He's really a delusional existence created by Shogun, the real Takumi Nishijou.]]
* TookALevelInBadass: He does by the end.
* UnreliableNarrator

[[spoiler: She also gets bonus points from having a blue-haired love interest, Takumi.]]
* YouGottaHaveBlueHair: Her hair is pink.
* ZettaiRyouiki: Type A.

!Nanami Nishijou
->'''Voiced by:''' Ui Miyazaki (JP), Creator/BrittneyKarbowski (EN)

* AnnoyingYoungerSibling: Despite the fact that Nanami's visits to her brother's apartment and her occasional attempts to make him go outside (which sometimes work) are because of her concern about her brother's well-being, he firmly believes this to be the case.

[[NotHerself doesn't take it well]].]]
* ClosetGeek: Whilst appearing to be a normal honor student, she keeps up with the latest anime and starts to buy the collectible figures, whilst maintaining her flawless image. [[spoiler:However, her geek side may be a ploy to earn Takumi's trust.]]
* CuteClumsyGirl: In the anime.

->'''Voiced by:''' Creator/AyumiTsuji (JP), Creator/KaraEdwards (EN)
