    Main Characters 

Takumi Nishijou

Voiced by: Hiroyuki Yoshino (JP), Todd Haberkorn (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 Neidhart/Knighthart).
  • Artificial Human: Quite literally a figment of someone's imagination. In this case, that of the real Takumi Nishijou.
  • Can't Stand Them, Can't Live Without Them: His attitude towards "3-D" girls.
  • Classical Anti Hero: 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.
  • Fake Memories: Specifically, his life from the age of maybe 12 or so until starting high school.
  • Flawed Prototype
  • Heroic B.S.O.D.: 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 Artificial Human.
  • 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.
  • In-Series Nickname: 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.
  • Mr. Imagination: 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.
  • Properly Paranoid: Yep, turns out Yua really did have ulterior motives in getting close to him, as should be obvious.
  • Split Personality: Takumi starts to think he had one that was responsible for the new gen killings. He was completely wrong.
  • Super Loser: He's a rude, selfish hikikomori with the power to make delusions real. 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!
  • This Loser Is You: He seems to be the type that is written to be so pathetic so that anyone could feel superior to him.
  • Through the Eyes of Madness: He is a self-described disgusting, delusional, otaku, hikikomori who is approached by 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.
  • Tomato in the Mirror: He's really a delusional existence created by Shogun, the real Takumi Nishijou.
  • Took a Level in Badass: He does by the end.
  • Unreliable Narrator
  • Wrong Genre Savvy: Sometimes he thinks of himself as a character in an RPG.
  • You Gotta Have Blue Hair

Rimi Sakihata

Voiced by: Eri Kitamura (JP), Carrie Savage (EN)

A second-year student in Takumi's class, who claims to be Takumi's friend. She is a person who gives Takumi emotional support during the weird events that he has gotten into, despite the fact that he doesn't remember befriending her.

Nanami Nishijou

Voiced by: Ui Miyazaki (JP), Brittney Karbowski (EN)

Takumi's younger sister and a first-year student in Suimei Academy. Because Takumi lives on his own, she makes occasional visits to his apartment to check how he's doing.
  • Annoying Younger Sibling: 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.
  • Finger in the Mail: Happens when she gets kidnapped. Although instead of a finger, it's her whole hand.
  • Hair Decorations: She wears a hairband.
  • Little Sister Heroine: Several 'Delusion' events play up this angle, such as with the indirect kiss scene.
  • Proper Tights with a Skirt

Yua Kusunoki (Mia)

A third-year student at Suimei Academy, who, after a warm introduction, is revealed to be following Takumi around. She's investigating New-Gen murders on her own for personal reasons.
  • Angsty Surviving Twin: Her twin sister Mia died in the "Group Dive," the first First Gen incident. Yua then launches her own investigation into Mia's death. She suspects Takumi is involved in the First Gen murders and pretends to befriend him under the ruse of being a girl otaku. When Takumi finds out her true intentions, she ... doesn't take it well.
  • Closet Geek: 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. However, her geek side may be a ploy to earn Takumi's trust.
  • Cute Clumsy Girl: In the anime.
  • Department of Redundancy Department: Serious-mode Yua has a habit of emphasizing sentences by repeating them several times in a row with slightly different phrasings.
  • Inspector Javert: Becomes convinced that Takumi is behind the New-Gen murders due to supposed split-personality
  • Meganekko
  • Rapunzel Hair: It goes all the way down to her waist.

Sena Aoi

Voiced by: Hitomi Nabatame (JP), Clarine Harp (EN)

A third-year student at Suimei Academy, who seems to frown perpetually. She's often seen walking around Shibya with a huge sword, although people aren't really bothered by it.

Ayase Kishimoto

Voiced by: Yui Sakakibara (JP), Stephanie Sheh (EN)

A third-year student at Suimei Academy. She plays in a band called "Phantasm" with a stage name "FES", whose songs lyrics appear to describe the events of recent murders.
  • Bookworm: Spends most of her time reading mythology. She even makes a number of mythological references in regards to the plot.
  • Cold-Blooded Torture: A form of chinese water torture was done to her in her backstory.
  • Emotionless Girl
  • Heroic Albino: Comes with silver hair, pale skin and reddish eyes.
  • Interrupted Suicide: Takumi's first conscious use of his delusionary abilities in the game is to create a flowerbed which breaks her fall after she attempts suicide by jumping off the roof of the school.
  • Mystical White Hair: A hint of her being the most spiritual and eccentric character in the setting.
  • Proper Tights with a Skirt
  • Rei Ayanami Expy: Is even part of the current page image.
  • The Stoic: She has a stoic expression on her face which rarely changes.

Kozue Orihara

Voiced by: Ayumi Tsuji (JP), Kara Edwards (EN)

A second-year transfer student that transfers into Takumi's class. She appears as a very quiet and sensitive girl to strangers, but to people who know her, she's a very happy and a bit childish girl.
