The main character. A medical student in his twenties and the sole survivor of a horrible car accident. Saved by an experimental medical treatment, he now sees the world in a contorted manner with the exception of one thing: a girl named Saya.

* AlasPoorVillain: Horrible his actions may have been after he realizes in the third ending that Saya is dead, he suddenly appears to have regained his humanity...just before he then chooses to smash his face in with an ax.

* BigBadDuumvirate: Becomes this with Saya halfway through, if the player decides not to cure his condition. He helps her in her goal to convert humanity into her species, killing everyone who gets in their way.

* TogetherInDeath: The only ending where he and Saya end up together is the one where they are killed, and she crawls up to him, caressing his face before she finally dies.

* UnholyMatrimony: With Saya, killing people for her sake.
* VillainProtagonist: If he refuses to correct his agnosia, he becomes an AxCrazy killer wholly supportive of Saya's plot to transform humans into her species. Downplayed however as the latter half of the game is set far less from his perspective.

* {{Yandere}}: His reaction to finding someone raping Saya was to take the nearest meat cleaver and go crazy hacking at the man with it. He is also willing to let the world be damned for the sake of their love.

* AlasPoorVillain: In the third ending, after she's mortally wounded and Fuminori commits suicide, she's reduced to pathetically dragging her dying body over to him as Koji repeatedly beats her to death while calling her a monster, only finally expiring when she touches Fuminori's face one last time. It ends up being quite possibly the most depressing scene in the entire game.

* LivingEmotionalCrutch: So very much for Fuminori. If he had never met her, he would have killed himself a ''long'' time ago. In fact, one of the three endings has him commit suicide immediately after seeing her dying body.

* StarCrossedLovers: With Fuminori. The only ending where they both survive is the one where he's locked up in a mental institution for the rest of his life, and she's out there somewhere still searching for her foster father, Ogai. The [[TogetherInDeath third ending]] makes this incredibly poignant.

* TogetherInDeath: The only ending where she and Fuminori end up together is the one where they are killed, and she crawls up to him, caressing his face before she finally dies.

* UnholyMatrimony: Again with Fuminori.
* VillainProtagonist: The {{Deuteragonist}} and LoveInterest who turns out to be a HumanoidAbomination alien BigBad out to assimilate humans into her species.

* {{Yandere}}: Rather than MurderTheHypotenuse though, Saya has [[FateWorseThanDeath a much worse fate]] [[AndIMustScream planned for Yoh...]]

* JerkassHasAPoint: While dehumanizing his former friends and acquaintances despite also knowing that they're not truly monsters due to his "agnosia" isn't the healthiest way to deal with his current situation, Fuminori isn't wrong to feel frustrated with the madness and disgust that his new senses cause him and the fear that telling ''anyone'' about it, besides Saya, would either be dismissed, be seen as "crazy", or be locked away and treated as a guinea pig. Never mind losing any semblance of a "normal life" regarding the [[TruthInTelevision stigma of having a mental illness in East Asian cultures]] if he did get his "agnosia" fixed. [[PlayingWithATrope That being said]], his choice of isolating himself and acting unnecessarily rude and nasty to others while FeelingOppressedByTheirExistence isn't truly helping the situation and, depending on the player, [[spoiler:could either lead to his suicide or all of humanity transformed]].

* NonActionGuy: Koji is a much better fighter than him because of this, and nearly beats him in their final duel before Saya intervenes.

* TrueBeautyIsOnTheInside: A non-romantic example that's played on a horrific HorrorHunger level after Fuminori learns of Saya's true nature, and how he can only find human flesh edible while viewing humans as [[EldritchAbomination disgusting creatures of flesh and pus]].

* TranshumanTreachery: In the Saya Wins ending, Fuminori is implied to have undergone a physical transformation off-screen to become a similar species to Saya. Though, with his BizzareAlienSenses, he would find the process comforting and would view the Earth as reverted to "normal".

* JerkassHasAPoint: While dehumanizing his former friends and acquaintances despite also knowing that they're not truly monsters due to his "agnosia" isn't the healthiest way to deal with his current situation, Fuminori isn't wrong to feel frustrated with the madness and disgust that his new senses cause him and the fear that telling ''anyone'' about it, besides Saya, would either be dismissed, be seen as "crazy", or be locked away and treated as a guinea pig. Never mind losing any semblance of a "normal life" regarding the [[TruthInTelevision stigma of having a mental illness in East Asian cultures]] if he did get his "agnosia" fixed. That being said, his choice of isolating himself and acting unnecessarily rude and nasty to others while FeelingOppressedByTheirExistence isn't truly helping the situation and, depending on the player, [[spoiler:could either lead to his suicide or all of humanity transformed]].
