"Will I still be the same person once I uncover the truth?"
The main protagonist, Essi is a girl with psychic powers whose mother died under questionable circumstances in an accident ten years ago. Essi's own memory surrounding the event is quite foggy itself; the only thing left behind from that day was a USB-drive disguised as a necklace given to her by her mother, and the recurring dream of a boy named "X". When she is invited to Xen Institute, Essi becomes determined to not only solve the recent murder case, but to finally unlock the secrets of the X-Note, and uncover the mystery of her mother's own mysterious death.
Abandoned Playground: Her most precious place to visit, based on the fact that she used to visit it with her mother.
Badass Adorable: When she trains hard enough, this trope comes into play. It's most noticeable in Oure's path, when she's actually able to deflect Loil's bullets.
Body Snatcher: In Area X, it's revealed that though the body is indeed Emma's daughter, Essi is mentally Ceria's daughter who was displaced into this dimension, resulting in the sudden development of psychic powers (Ceria's Essi had them; Emma's daughter originally didn't).
Jack of All Stats: Essi is one of the few known psychics to be able to use psychokinesis, clairvoyance, and telepathy. That said, she doesn't particularly excel in any of these different branches of psychic power, and she has to train everyday to be decent in each category.
Memento MacGuffin: Her X-Note USB necklace. However, the full secrets of the X-Note are only revealed in one route. The others have Essi give up solving it, choosing not to uncover the mystery surrounding her mother's death.
Tragic Keepsake: The X-Note necklace that her mother left her on the day of the accident.
Trauma-Induced Amnesia: The reason she doesn't remember her early childhood is to spare herself the trauma of X's suicide.
Tsundere: In Yuon's route as a Type B, and in Anon's route as a Type A.
Was It All a Lie?: When she finds out Yuon was manipulating her feelings and using her to tap into his own psychic abilities, she levels this accusation at him.
Why Can't I Hate You?: When Essi chooses to go talk to Yuon in Anon's path, she can't bring herself to betray Anon to Yuon as Scid's killer, as she has grown to love him too much.
Your Approval Fills Me with Shame: Inverted. Essi initially commends Anon's information gathering skills, only for him to proudly ask if she's impressed. Essi regrets praising him.
"How long can I struggle when everything I believe for is denied?"
A serious young man with many connections at Xen Institute, Yuon is the student who invited Essi to investigate the murder of Dr. Scid, who happens to be Yuon's father. Coolly calculating and somewhat manipulative, he pushes Essi to transfer into Xen Institute, and encourages her to make use of her psychic abilities to help the investigation along. He is hard-working, albeit very messy, and is often found in his office, surrounded by papers.
Broken Ace: He strove to become an amazing student in an attempt to gain his father's attention, only for his father to end up dying, leaving Yuon to feel like everything he's done in his life to be pointless.
Clear My Name: The purpose of Essi investigating his father's death. Though that's only half the story.
Dark and Troubled Past: Yuon's mother died when he was very young, and his relationship with his father has been poor ever since they both got news of his older brother's death. Since then Yuon has buried himself in academics and chess in order to fill the void left behind. His inability to connect to his father also led to an inability to connect with others, leaving him as the Socially-Awkward Hero that he is. Heck, even at the beginning of the game, he states that his main motivation behind solving Scid's murder isn't to find his father's killer, but to clear the police's suspicion of him as the culprit.
Desperately Looking for a Purpose in Life: Everyone he's cared about and/or strove to impress has died by the present, leaving him to feel like he's lost his way. He admits in his route that he doesn't actually care about finding his father's murderer, as it wouldn't change anything; hiring Essi was just a distraction from his issues.
Foreshadowing: While they could be chalked up to him being a secretly nice guy, there are hints that he's not really interested in solving any of the mysteries, despite hiring Essi supposedly for that purpose. Namely, whenever he tells Essi not to push herself too hard over getting the job done and that there's no time limit, even though you'd think he'd want to get this solved as quickly as possible, what with him being the prime suspect for the murders. The longer Essi takes, the longer Yuon has an excuse to keep her around.
Hidden Depths: A pretty talented artist, though he never pursued the craft because he thought his father wouldn't approve.
Irony: As Yuon himself notes, it's ironic that someone as stiff and inflexible as him would have the ability of 'Adapt'.
Meaningful Name: "Yuon" is a corruption of the word "young". This hints not only at his younger brother status, but also at his rather immature tastes, despite his dislike of being treated as a child.
Memento MacGuffin: His Mr. Puffy keychain that he received from his brother, as well as his own X-Note USB.
No Social Skills: Essi's initial impression of him leads her to believe that he is a typical Manipulative Bastard, but as she continues to interact with him, it becomes clear that Yuon just doesn't know how to properly interact with others.
Orphan's Ordeal: Having lost his family over the course of his life has messed the guy up.
Parental Neglect: He's always been overlooked by his father in favour of his brother—first, because his brother was ill, and then again because his brother lived at the institute where their father was working (while Yuon was sent away for his own good), and then once more because his brother died, leaving his father unable to cope with the grief. Even afterwards, his father admits that he doesn't know how to talk to Yuon anymore and fears that Yuon blames him for everything. Area X shows Elcia trying to help them re-connect, but Yuon's route makes it clear that it doesn't work out.
Perpetual Frowner: His default expression, though it's only a mild frown, and it's clear that he just has trouble with communicating with others.
Poor Communication Kills: Arguably, the conflict in his path comes down to this. He leaves Essi in the dark about many things surrounding the case, with the most tension being caused by omitting the fact that he possessed psychic abilities as well. Taken to its most literal extreme in his bad end, and with Essi following suit. Because she is suffering from her own Heroic BSOD due to his death, she doesn't defend herself when the authorities arrive on the scene and start accusing her of murdering him.
Will Not Tell a Lie: Or rather, he will never break a promise. It can be dismissed as a casual remark when he claims this early on in the game (and Essi is doubtful), but his route reveals that everyone he's loved ended up breaking their promises to him, which he's never really forgiven them for.
Young and in Charge: He actually inherited Xen Institute from his father, as his mother died when he was young.
Younger Than They Look: Yuon is around Essi's age, maybe only a few months older. Yet he looks very mature for his age, and has a large responsibility in running the school even as a student at Xen Institute.
"Dreaming is the only thing I can do."
A young-looking boy whom Essi meets while wandering in the corridors. He is very innocent and carefree, and takes an earnest interest in helping Essi when he can, though usually he is of little help himself. Childlike in appearance and demeanor, Essi quickly and easily befriends him, and enjoys spending her freetime talking with him.
But Now I Must Go: Late in his route, he fades away in front of Essi, then comes back to spend some of his final moments with her. In the Bad Ending, he stays gone. In the denouement of the Good Ending, there is a Flashback to when he is fading away the second time. Essi catches him as he is fading in the middle of the night, and he manages to get in a few last words. He tells her that he won't say good-bye, because he believes that they will meet again one day.
Closed Circle: He is literally unable to leave one of Xen Institute's corridors. This might be due to the fact that, even though he uses his ability regularly, he is still not aware that he is alive and thus can't practice expanding his range.
Convenient Coma: While it is convenient for the story, in the end, this is subverted. The doctors who tend to him in the hospital say that he has a very slim chance of waking up, and that it was a miracle that he was still alive after being in a coma for ten years. Nevertheless, Essi is determined to wait for the day when he finally wakes up.
Dark and Troubled Past: He is Yuon's older brother, and the closest friend that X had in the Institute. At a young age, he developed diabetes, genetic from his dead mother. One day while standing up to the other children who were bullying X, he also got hurt, triggering X's Berserk Button. Caught in the fight, Oure fell into a coma afterward, and believed himself to be dead. Confusing his Astral Projection with being a ghost, he tried wandering the school only to find that he couldn't leave the corridors, and he grew resentful of watching the clouds pass by in the outside world, while he himself was trapped there.
The Ditz: Occasionally seems this way in his interactions with Essi, when in this day and age, he doesn't know what a cell phone or USB drive is, though this is justified.
Hidden Depths: Hints at this with a few of his conversations with Essi, but very notably, he mentions early on that when she met him, he found a sense of new hope.
Hopeless With Tech: He is very ignorant of newer technology; although he sees it all around him, he has no idea what each device is called or how they work.
Ill Boy: He has always had a weak body from a young age. Also, he has diabetes, though he never appears to have to take an insulin shot. It's justified in that since he is really an Astral Projection, he understandably doesn't have this limitation, though his physical body still needs its daily medication.
Tomato Surprise: The Oure that Essi has been visiting is an Astral Projection, and he did not die ten years ago as everyone else had once thought; he was in a coma and kept alive under the Institute. This is deducible with the hints given in his route, however.
You Can See Me?: Though when Essi first discovers that he lacks a physical body, he becomes transparent, as he should have been.
"[Insanity] is the only way for me to remain sane in this crazy world."
A playfully annoying student whom Essi meets during her visit to the computer lab, Anon takes great pleasure in tormenting Essi for his own personal enjoyment. He is also a skilled hacker and spends his time in the computer lab digging up info about the institute and other students as well. He offers to help Essi in her investigation whenever she needs it, though she often finds him to be obnoxious to work with most of the time. He is the boy named "X".
Dark and Troubled Past: Probably the darkest one out of all three Love Interests; his past was so traumatic that he was a Death Seeker at the age of six. He arguably needed to create different personalities for himself in order to keep from going completely insane. Now it sort of holds him together, but at the same time, he feels an emptiness in his true personality.
Death Seeker: When he was a lot younger. And he is still this way now, as it's hinted in his route that when Essi chooses to pursue Yuon or Oure, and thus does not interact with him beyond her initial visits, he gives up his Quest for Identity and chooses to die.
Kick the Dog: When Anon reveals his Lack of Empathy, Essi tells him that it can't be true, as they spent lots of fun times together. When she asks if it was all a lie, Anon shoots back asking what she would do if he said that it was a lie. This sends Essi straight to tears, and when Anon asks if he should lie to make her feel better, she cries even more.
Meaningful Name: As a Playful Hacker who is always found in the computer lab, and spends his time on forums to discover new gossip and information, "Anon" fits well enough. Even more so, his name refers to his lack of identity, and the emptiness he feels when thinking about who he is and where he came from.This also hints at him being the "unknown" or X.
And then he uses this info to buy her a black bra for her birthday...
Power Incontinence: He has difficulty controlling his powers for the most part, as they tend to manifest unconsciously. However, his emotions and the amount of control he has over them also result in this, so he is at least aware of what he's doing when this happens.
Repressed Memories: As well as him having a great disconnection between all of his collective memories, leading to his Quest for Identity in the first place. However, even though it's repressed, he still subconsciously remembers that torture that Scid subjected him to.
Split Personality: Although his true problem is much closer to having actual schizophrenia, Anon appears to display this trope late into his route when his Super-Powered Evil Side subconsciously activates.
Stepford Smiler: Type B. He picked up this behavior from the merchants he traveled with.
A mysterious person who watches over Essi from afar. Rexus' entire persona is shrouded in mystery, and even though Essi is able to obtain a few answers from him regarding himself, she's unsure how much of it is true. Nevertheless, Rexus is helpful and friendly, providing a friend for Essi to confide in, as well as some vital clues needed to solve the mystery.For more information, see Area X.
Adorkable: In his first spoken appearance and in a few of Essi's interactions with him after that. When they first met he took her bluff seriously and thought she was going to call the police.
Obfuscating Stupidity: If the author's notes are to be believed, Rexus' true personality is a lot different than the silly one here.
Red Herring: His mysterious persona, opportune helpfulness, and insight in Essi's life eventually leads her to suspect that he is X. His name doesn't help matters.
Screw the Rules, I Have Connections!: Damn, if he doesn't. He is the one most responsible for taking care of the major and minor details Essi usually has to resolve at the end of each path. He is easily the most well-connected character, surpassing even Loil.
Socially-Awkward Hero: Initially doesn't deal well with chatting with Essi, but as they interact more, he shows himself to be more normal.
The first authority figure Essi meets in Xen Institute and its last surviving founder. Due to Essi's involvement in the case, Yuon assigns her to Acia's class. Though a kind and helpful woman, Acia often hesitates to personally take action.
Cowardly Lion: She is a self-proclaimed coward, who holds guilt for not supporting Emma in the incident ten years ago.
My Greatest Failure: She remained silent when Scid and Emma confronted her for her support on their opposing decisions in dealing with X. Acia kept silent, and deeply regrets that day, partly blaming herself for Emma's death.
Sincerest Form of Flattery: She states that she became a psychiatrist, like Essi's mother, out of her admiration for her. However, she lacked the talent that was needed to succeed in that field, and so, she became just another teacher at Xen Institute. Acia was actually more talented as an artist, and Emma was disappointed that she simply followed her into psychiatry instead of choosing to pursue a career in that field.
Spot of Tea: When Essi helps her out on her first Saturday at Xen Institute.
One of the other founding members of Xen Institute and its previous principal, Dr. Scid is the victim of the murder case that Yuon recruited Essi to solve. He suffered from internally caused brain injuries; Yuon quickly deduces that only a psychic was able to murder him.
Big Bad: Arguably, he was the Big Bad of Anon's route, as the X-Note ultimately revealed what happened ten years ago, even though he was already dead beforehand. Then in the present he gets Hijacked By Loil.
Scid: In my opinion, real sweets should carry a little bitterness before you can savor its sweetness.
Generation Xerox: Very similar to his son Yuon in terms of looks and personality.
I Gave My Word: Promised his wife before she died that he would protect their family. So when he is unable to save his son, he loses it.
It's Personal: His son was critically injured during X's rampage against those who were bullying the two of them. Believing his son to be dead, he abandoned his morals when it came to studying X and hooked him up to a machine that tested his powers, but at the same time strained him mentally, and damaged his psyche beyond repair.
Like Father, Like Son: Played straight for the most part with Yuon, though he is less self-assured and constantly worked for his father's approval. Also, Scid is not quite as noble. Averted with the more cheerful Oure, who takes after his mother.
Mind Rape: Subjected X to this as a way to both study psychic ability and exact revenge for his lost son.
Papa Bear: Very protective of his family, due in part to the guilt he feels over not forseeing his wife's condition that led to her death. This is especially true for Oure.
Parents as People: He's aware of the Parental Neglect he's inflicted on Yuon, and isn't continuing it because he's a jerk, but because as a person, he really has no idea how to talk to Yuon anymore.
Relative Button:When he finally comes face to face with X after ten years, he explodes with anger and attempts to kill him. Unfortunately for him, X is a ridiculously strong and destructive psychic.
Revenge: His most glaring flaw. His despair over losing his first son led him to blame and cruelly torture X, meanwhile creating a rift between him and his remaining son. Even worse, it's hinted that he might have had some involvement in orchestrating Emma's death because she spoke out against his methods and attempted to take X away from him, though this question is left unanswered.
Another one of the founding members of Xen Institute, Loil was declared to be abducted before the start of the game. Although Essi pins him as a suspect for Scid's murder early in the game, Yuon states that it is impossible for Loil to be the culprit of Scid's murder, as the damage was done psychically and Loil lacked any special powers of his own.
Big Bad: Though it's eventually revealed that he's actually working for some government higher-ups.
Driven by Envy: Suggested by Anon in his confrontation with Loil in his Bad Ending. Children, psychics, those with special minds-Anon suggests that Loil pursues them because he is envious of those things. He had been fascinated by children because he couldn't return to his own childhood, and he never possessed psychic powers or a special mind.
For the Evulz: When it isn't for business, he likes watching the more extreme experiments done on the children for his personal amusement.
Hijacked by Ganon: He really doesn't show up much at all during Anon's path, and the main conflict involves past events with Scid, who appears to be even more villainous than him in this path. He only really comes in at the end to fire off a bullet at Anon and then send the government after Anon and Essi.
And then there's also the matter of the children that he found on his last trip to the north...and the fact that he brought them all back with him.
Emma: They are merely toys for his amusement.
He even states that he was planning on getting rid of Oure once he got older, but couldn't bare to do it because he looked so youthful.
Manipulative Bastard: Very much so; he uses the children in the facility for his own gain, concealing Oure's comatose state from the others in the facility, and manipulates Yuon and Essi in his route. He is also pretty much responsible for getting the other founders to turn on each other, though it's hard to say that Scid wouldn't have tortured X just for putting his son in a coma either.
A mysterious boy that appears in Essi's dreams, and is connected to her mother's death. His name, given to him by the founders of Xen Institute, is also used in naming the X-Note. Currently, he has taken on the identity "Anon".
Death Seeker: As seen in the opening to the game and even when he's older.
Despair Event Horizon: Just when you think that he can't be more broken than he already is, the story says otherwise.
Divine Intervention: Saved the children of his village through his awakening psychic power. They could only describe it as a strange power that protected them, and don't actually think he deserves credit.
Harmful to Minors: The kid suffered through the Northern War, the most destruction of which was caused by an explosion from a swamp that was tainted blood red. He was then later bullied by the very children he saved, and indirectly caused what he believed to be the death of his only friend. He was then tortured by said friend's father in an act of revenge, and was barely rescued by Essi's mother, only for his savior to die in a car accident, which he then blamed himself for by not attempting to save her. By this time, he was already long gone across the Despair Event Horizon, and instead chose to end his life then and there.
Sanity Slippage: He already slipped pretty far after seeing the massacre of his village. However, he showed some signs of recovery when Oure befriended him. After he thought that he ended up killing Oure, he was subjected to further tradgedy and loses it, eventually crossing over the Despair Event Horizon.
Single Issue Psychology: Averted. Though he does mainly suffer from PTSD, the other things he was subjected to in his childhood also damage his psyche severely.
The Sociopath: A borderline example. He really cannot see the point in caring for others' situations, although considering everything he had experienced from the point of his introduction, it's easy to see where this viewpoint comes from. He's more sympathetic than many other examples, and despite his violent outbursts, his lack of empathy comes from being a Shell-Shocked Veteran.
Shell-Shocked Veteran: A child who watched and survived the destruction of his village in the Northern War.
