The protagonist. David moves into a new apartment during a rough point in his life, and immediately strange things occur which prompt him to search for the mysterious previous tenant.
- Action Survivor: Despite taking many actions that could be very detrimental to his health, David can hold his own in a fight and is rather good at surviving weirdness.
- Arbitrary Skepticism: David still feels the need to call Paul an "occult fanatic" even after all the weird stuff he's been through.
- Because You Were Nice to Me: The reason why Sophie falls in love with him in The Sandman.
- Big Brother Instinct:
- Big Damn Heroes: Pulls this a few times. Each person he meets on his quest—Sissi, D, Fluffy—he ends up having to save from being killed by the Crooked Man.
- Break the Cutie: He really is a genuinely sweet guy, but the things he faces puts him through utter hell, both before and during the game. Turns out this is the only way to ultimately save his life...
- Broken Tears: David's face is covered in tears when he's contemplating suicide.
- Cassandra Truth: Is never able to convince anyone that the Crooked Man is after him or them until it's almost too late. Paul believes him though; he saw it too.
- Character Development: A sweet but severely insecure and tormented guy. His encounters with the Crooked Man, Sissi, D, and Fluffy ultimately force him to become more confident and thoughtful of how he views life and the choices he's made.
- Determinator: Keeps trying to find the former tenant, no matter how many times he almost dies as a result.
- Distressed Dude: Briefly gets possessed by the Crooked Man who tries to compel him to suicide and his best friend Paul has to come save him. Or else fail spectacularly.
- Driven to Suicide: The Crooked Man tries to force him to do this. If Paul fails to drive it away, he succeeds.
- Establishing Character Moment: When he finds a note in his apartment during the prologue about ghosts and spirits, he makes an extremely casual comment of not caring if they haunted or killed him, telling you already that the guy is NOT at all okay...
- Extreme Doormat: Shirley accuses David of being this, saying that he wasn't kind, but insecure and that he didn't have a personality of his own. When David denies it, she leaves him.
- Freak Out!: Had one in the past where he almost killed his mom. Remembering this some time later causes him to have another one and almost kill himself with the Crooked Man's assistance.
- Heroic BSoD: Suffers one when faced with an image of his mother and recalling some very painful memories.
- Laser-Guided Amnesia: After Paul saves him from the Crooked Man compelling him to shoot himself, David doesn't seem to have any memory of the incident, is confused that Paul was beating him, and insists that he was perfectly normal the whole time.
- Mommy Issues: One of the biggest things looming over his life and keeping him depressed is that his mother has a tumor in her brain and can't even recognize him. She got so upset, thinking he was a stranger invading her home, that she had a Freak Out!, leading to him also having a Freak Out! and almost killing her. Remembering that incident, in particular, is what causes his Heroic BSoD.
- Murder-Suicide: If Paul tries to grab for the gun while David is being forced to commit suicide, David will end up accidentally shooting him. Then he gets even more upset and shoots himself anyway.
- My God, What Have I Done?: After he freaks out and nearly kills his insane mother. This particular memory is so traumatic that remembering it some time later causes him to go into a Heroic BSoD.
- Nice Guy: A very important character trait. David's kind personality allows him to bond with Sissi (who lampshades it), D, and Fluffy, but the Crooked Man also takes advantage of it. A book specifically says that "they" (spirits, the Crooked Man) would take advantage of people's kindness to manipulate them.
- Sanity Slippage: His friends suggested he move for a change of pace and are shown to be very worried about him, and even his ex-fiancee calls him to check up on him. He had a Freak Out! when his mom had a particularly bad breakdown and almost strangled her sometime in the past. Remembering this incident later leaves him so upset that the Crooked Man is able to possess him and almost compels him to suicide.
- The Southpaw: In the times we see him holding something in his hands, like the lighter at the hotel and the gun when he is being possessed by the Crooked Man, David is holding it in his left hand.
- Tragic Dream: His dream of being a pilot was dashed because he is colorblind.
- What an Idiot!: Some of his choices don't seem to make a lot of sense over the course of the game. Makes more sense when you consider how nearly suicidal the guy is.
David's friend, Paul is the one who helped David move into the apartment. He is later playable near the end of the game, when he has to stop David from shooting himself.
- And Now for Someone Completely Different: You briefly play as Paul.
- Big Damn Heroes: He goes all the way to an abandoned hospital, runs up several flights of stairs, and punches David in order to save David when it seems he's being manipulated into shooting himself.
- Cassandra Truth: Dialogue late in the game hints (and his character profile confirms) that Paul's always been able to see or at least "feel" supernatural things, and David and Marion had never believed him about it, leading to David being surprised when Paul believes him about the monster.
- Chekhov's Hobby: Early on David makes an offhand remark about how Paul's into occult things. Paul can see dead people, hence him being able to follow the advice of Sissi, D, and Fluffy, and ultimately saving David from one of the Crooked Man's nastiest attacks on him yet.
- Happily Married: To Marion.
- I See Dead People: When he and Marion go to the abandoned hospital to find David, he can see Sissi, Fluffy and D, while Marion cannot.

After he saves David, David is surprised Paul believes him about the Crooked Man.

After David is attacked by the Crooked Man, D softens up and helps David by giving him an energy drink to boost his health.

During Marion and Paul's segment, he also encourages Paul to find David.

- What Happened to the Mouse?: Unlike Sissi and D, Fluffy left in a fit after realizing that his mother is never coming back and didn't let go like the previous two. While David was about to chase after him, he stops after realizing his own Mommy Issues, and decides to just to head back home which leaves Fluffy's fate uncertain. Luckily, it turns out that Fluffy is just a memory "facet", meaning that he wasn't in danger to begin with, outside of The Crooked Man.
A twisted entity that starts following David everywhere on his journey, and tries to kill him and his companions at every location. It turns out he's the tenant David's been looking for this whole time. The reason he stalks David is because he hates David for being so much like him and wants him to die for it... and because some part of him wants David to not go down the same path he did and end up like him.

The Crooked Man is all his anger and resentment over all of that.

According to one of the hospital entries, Duke talks about wanting to kill his child self, confirming that he wanted to kill Fluffy more than David.
