All spoilers will be unmarked.
Hewie becomes her constant companion and her only line of defense against the dangers presented by the castle and its inhabitants...
Fiona is a bearer of Azoth, the mystical essence of life. Everyone except Debilitas wants it for their own reasons, and they're more than willing to kill her for it. The mark on her back isn't a graphical quirk, but a symbol that shows that she has Azoth within her.
- Actual Pacifist / Reluctant Warrior: "Why must I kill just to keep myself alive? I hate this place. I really do."
- Beauty Is Never Tarnished: Always maintains that pristine look, never getting sweaty or disheveled despite constantly running for her life.
- Beware the Nice Ones: While she seems helpless and timid and prone to running away from danger, the player can still choose to fight off her assailants with attack items, melee attacks and command her companion Hewie to jump on them and gnaw their jugular off. And while she is also a sweet-natured girl who detests violence of any kind, her final line to Lorenzo shows that she's willing to make an exception:"This time... you really are dead. You bastard."
- Big "NO!": Fiona lets out quite a few of these throughout the game, starting with when she wakes up from a nightmare. The "no" is even repeated three times for emphasis.
- Used during several of her most gruesome death scenes.
- Her reaction during Ending D upon realizing she's been captured and soon to be impregnated by her uncle.
- Also how she reacts to Lorenzo revealing his true colors.
- Blessed with Suck: Her body is full of Azoth, which is said to have many valuable uses, including eternal youth and immortality. Unfortunately, because it's such a precious substance, her captors also want to get their hands on it.
- Break the Cutie: She's kidnapped after her parents are run off the road in a fatal car crash and awakens to find herself locked in the basement of an old castle, where everyone and everything is either trying to kill her, or rape her, for her Azoth. Which she's never heard of and hasn't the faintest idea about. She then spends the entirety of the game running for her life, hiding in dark corners and trying to protect her virginity. Thank God she's at least got Hewie to protect her.
- Damsel in Distress: Haunting Ground uses this as a gameplay mechanic, by making it so Fiona has to rely on Hewie as her primary means of defense. This is especially the case when she's in full panic mode and unable to move. When she's being pursued, her only recourse is usually to run and hide until the danger's passed.
- Deadpan Snarker: Not in any cutscenes, but some of her thoughts and comments throughout the game definitely have a snarky element to them.
- Fiona Grabs a Gun: She gets a six-shooter with her cowgirl costume, which changes her basic attack from a kick to firing shots. While this allows her to attack from a somewhat safer distance (it's only mid-ranged), the player has to take care not to accidentally shoot Hewie when trying to pet him.
- Foot Focus: Many of the game's cutscenes focus directly on Fiona's bare feet. Her "Under the Scalpel" costume and an altered version of her default costume also both leave her barefoot.
- Gaia's Vengeance: A non-flora version. Fiona was basically created to be the embodiment of Life, and Life is not fucking happy with the walking skeletons and perverted mockeries of humanity that Lorenzo has created.
- A Girl and Her X: Both the game's narrative and the player's success hinge on the dynamic between Fiona and Hewie, since Hewie is her only means of defense. She also has to rely on him to retrieve items from areas that are inaccessible to her, and he's integral in solving several of the castle's puzzles. How quickly he responds to Fiona's commands depends on how well she treats him.
- Girly Run: Hers is about the same as Yuna's.
- Hair of Gold, Heart of Gold: She's a fair-haired, fair-skinned virgin and an innocent who finds herself in the wrong place at the worst possible time.
- Haunted Heroine: Fiona has never heard of Belli Castle and wants no part of it, and with good reason. As the game's title implies: it's haunted. Worse, the malevolent architecture and its inhabitants are all either trying to kill her or rape her. The only way out is by surviving its dangers long enough to unravel its secrets and learn the unsettling truth about her family.
- In the Blood: It's never really explained how she can become an effective alchemist in a single night with limited resources, so this trope is presumably the reason. That, and, when your body is already filled with the metaphorical holy grail of alchemy, reverse-engineering all the other stuff the art can create might be relatively easy.
- Kick Chick: Fiona's basic attack. Gets stronger if she's wearing harder boots.
- Lampshade Hanging: "Is someone just trying to scare me?"
- Laughing Mad: In Ending D, Riccardo succeeds in capturing Fiona. The realization that she was raped by her uncle and is now pregnant with his child/reincarnation causes her to lose what's left of her sanity and laugh despondently.
- Lust Object: Subverted. While Riccardo does desperately want to get between Fiona's legs, it's her Azoth that he's after rather than her body. If he succeeds in impregnating her, she'll eventually give birth to his reincarnation. Daniella envies Fiona as a resultnote and attempts to Slut Shame her for it (seen at 32:46-33:54)..
- MacGuffin Girl: Deconstructing this is almost the entire plot of the game. Fiona's body is filled with a magical, life-granting elixir, which seems great, except it means that the easiest way for people who want said elixir to get at it is to cut her open and take it.
- Ms. Fanservice: Fiona is one of, if not THE most intentionally sexualized character in all of gaming. The game does not play it for laughs, as most of the stalkers have creepy sexually-charged motives, and Fiona is immediately terrified and appalled at their behavior.
- Nice Girl: Demure, polite, and a lover of animals in general. Upon meeting Hewie the second time and finding him bound to a tree, she immediately rushes to his aid. This act of kindness is what allows her to escape from the castle.
- Only Sane Woman: Fiona is a normal college student with no weird quirks and is completely out of the loop regarding her family's history. She reacts to the various freaks and bizarre sights in the Belli Estate with fear and repulsion, and to the constant talk of Azoth with confusion.
- Screw This, I'm Outta Here!: Invoked during Ending C, which is only possible with a New Game+ file. If Fiona spares Debilitas and visits him in his shack afterward, he'll give her the key to the main gate, which allows her to leave the castle early and effectively circumvent 2/3 of the game.
- Strong Family Resemblance: Fiona looks exactly like a younger version of her mother, Ayla◊.
- Took a Level in Badass: By the end of the game, she has overcome her fear of her adversaries, earned the respect of Debilitas, if she spares him instead of killing him, and finally succeeds in escaping from the castle with Hewie.
- Took a Level in Jerkass: Optional at the player's behest, and doing so will lead to the worst ending of the game.
- Virgin Tension: Fiona's is constantly at risk since Riccardo plans to rape her in order to impregnate her with himself. When he finds her unconscious in the forest, he even strips her down and gives her an ovulation test.note
- When She Smiles: It's rare that you see it, given the circumstances, but it's almost angelic when she does.
An intelligent white German Shepherd Fiona found tied to a tree. Seeming well-cared for, he drives off Debilitas and becomes a valuable companion to Fiona. He is able to detect traps and nearby enemies, sniff out hidden items, and get items Fiona cannot reach. Like any pet, the more Hewie likes Fiona, the faster he'll respond to her call and commands. He is Fiona's main form of attacking and can be praised for doing good things and scolded for being disobedient. This ordinary dog seems to be Fiona's very key to escaping the castle.
Being mean to Hewie will cause him to die and give you the worst ending in the game.
- Action Pet: White German Shepard that listens to you while ripping people a new one on demand? Yes please!
- Canine Companion: Hewie serves as Fiona's primary means of defense and is also required for solving many of the castle's puzzles. At other times, he's used to snag items that are in areas which are inaccessible for Fiona.
- Deadpan Snarker: His comments regarding Fiona or the situation tend to be rather hilarious and snarky, though they are viewable only on Hard Mode.
- Death by Newbery Medal: A requirement to get Ending D.
- Evil-Detecting Dog: He warns Fiona before Debilitas attacks. He'll also bark and growl if there's a stalker, death trap or luminescent nearby.
- For Want of a Nail: Played with in the worst ending, where his absence causes Fiona to be trapped in Ricardo's dungeon.
- I Will Protect Her: Proof that dogs can be a girl's best friend too.
- Killed Off for Real: This can happen on Hard Mode if you allow him to sustain too much damage without treating his wounds, which results in a Non-Standard Game Over. Also happens in Ending D.
- Mysterious Past: Hewie's collar reveals he had another owner at some point, but even after escaping the castle, he doesn't seem interested in returning to them. The game seems to imply that he was once owned by Lorenzo.
- Non-Human Sidekick: Acts as this to Fiona.
- Pet Interface: As per the Canine Companion entry.
- The Power of Friendship: Implied to be how he walks away from a gunshot wound, even if Fiona doesn't come help him, given that he only dies when his relationship with her is at its lowest possible value.
- Relationship Values: An important aspect of the game. How quickly and reliably Hewie responds to Fiona's commands depends entirely on how well the player treats him. However, if the player mistreats him, Hewie may ignore Fiona and, in extreme cases, he may even attack her himself!
The mentally-stunted gardener of Belli Castle. He mistakes Fiona for a big doll and pursues her, but harbors no murderous intent; he just wants to play. Problem is that he hugs her too hard.
Fiona can choose to let him live by dropping the chandelier on him during his boss fight, or she can end up killing him with Hewie and the stun bombs she finds scattered around the castle. On a second playthrough or beyond and if Fiona spared him previously, using the chandelier on Debilitas will make him give you a castle key if you visit him afterwards, which leads to Ending C.
- Anti-Villain: Unlike every other stalker in the game, Debilitas is not trying to kill Fiona. He just likes playing with dolls, and seems to think Fiona is a much better toy than what he already owns. He's like a child who does not know his own strength and hasn't got a good grasp on not breaking things yet.
- And Call Him "George"!: Thinks Fiona is a doll and his first reaction is to hug her, which can result in him incidentally crushing her body due to his strength.
- Ax-Crazy: Subverted, unlike every other resident of Belli Castle. He is merely misguided and relatively docile when not pursuing Fiona.
- Bear Hug: This is how he kills Fiona if he catches her, hugging her until her ribcage snaps.
- The Berserker: After Fiona picks up the Lunar Refractor, Debilitas becomes enraged and starts permanently sprinting after her. He is also more likely to drop on top of Fiona and instantly kill her if she is tired or panicking.
- The Butcher: Seen preparing meat in the cinematic intro.
- Dumb Muscle: Very mentally deficient and has the mind of a young child. He can easily lift Fiona off the ground and crush her ribs in mere seconds.
- Esoteric Happy Ending: He gets to stay in the place he's accustomed to, and it's now free of all the sadists who used to live there.
- HeelFace Turn: Should Fiona spare him. He wasn't evil to begin with, though, just unable to understand the gravity of his actions.
- Defeat Means Respect: Happens if you drop the chandelier on him.
- Extreme Doormat: He is extremely subservient to Riccardo, giving up on pursuing Fiona the moment he is scolded. Justified in that Riccardo is the castle's keeper and his creator.
- Manchild: Even without counting his childish demeanor, he loves to play with dolls.
- Meaningful Name: "Debilitas" refers to his mental deficiency, including the deformed features he has physically such as his eyes and hunched back.
- Our Homunculi Are Different: Like the majority of the stalkers. He in particular was created with samples of dog placenta, which may or may not have played a part in how he turned out to be a failure.
- Sole Survivor: Should Fiona spare him and not escape early, he essentially inherits Belli Castle, with all its other residents dead and Fiona leaving.
- Spanner in the Works: Becomes one in New Game Plus, as Ending C is achieved by Debilitas giving Fiona the key to the front gate of Belli Castle. This completely derails the plans of every stalker in the game, caused by the lowly groundskeeper they'd ignore otherwise.
- The Speechless: Cannot speak coherently and only communicates with short phrases and gestures. He does, however, understand English and Latin commands.
A maid with ethereal beauty, Daniella appears mostly emotionless and harmless to Fiona... at first.
Daniella believes herself to be a homunculus, but is, in fact, a normal (though infertile) human woman. After being kidnapped at a young age, she was brainwashed into believing that her master, Lorenzo, created her to be the "perfect woman." However, she is unable to feel pain (which explains the blood on her fingers), has no sense of taste, and cannot feel pleasure. With feelings of being incomplete, Daniella is driven to insanity. She screams at her reflection, and wants Fiona's Azoth to be a complete being... even if it means cutting out Fiona's womb while she's still alive. She tends to swing back and forth between doing her duties as a maid, and has an extremely unnerving laugh.
- Aloof Dark-Haired Girl: When she's not in Ax-Crazy mode (which she usually is), she'll behave like this mixed with Emotionless Girl. However, her hair is paler than most examples.
- Ambiguously Gay: Her hair is lavender, a common color associated with LGBT, she can literally hide in a closet, and she has numerous Les Yay moments with Fiona...
- Ax-Crazy: She could quite easily be a contender for one of the most psychotic female characters ever in gaming. She's got a long list of mental issues that combine to make her horrifying.
- Become a Real Boy: Her ultimate goal. Except... she is already a real woman and not a homunculus as she believes herself to be, according to Word of God. And the most depressing part of Daniella's backstory is how, due to her upbringing, drug experiments, and abuse from Riccardo and Lorenzo, she never comes to realize that she was in fact human all along and didn't need to hunt down Fiona in a desperate attempt to be "complete."
- Broken Bird: Evidently became this after Lorenzo kidnapped her as a child. She can't remember her past, hates herself for being infertile, is implied to cut herself in an attempt to feel pain, and is used as a punching bag by the sadistic Riccardo. It's more than likely that this chain of events caused her to become The Stoic.
- Creepy Housekeeper: Before she goes bonkers, this is the impression one will get from her.
- Emotionless Girl: She appears to be this to a T at first, but she eventually subverts it HARD once she finally snaps and becomes full-blown Ax-Crazy.
- Feel No Pain: Played straight, coupled with her inability to feel any physical stimuli.
- Freak Out!: Daniella does not like mirrors. If she runs into an uncovered one, she will spend at least a couple minutes clutching her head and screaming hysterically. She'll break the mirror once she gets control of herself.
- Giggling Villain: In her manic phases, and at the prospect of gaining Azoth.
- Go Out with a Smile: When she dies, she's grinning from ear to ear because she's overjoyed to finally experience feeling.
- Head Desk: Does this against a mirror to gain her initial weapon.
- Impaled with Extreme Prejudice: She goes for this when finally catching Fiona. She also ends up impaled by a gigantic shard of glass.
- Lady of War: Daniella is a very elegant and feminine maid who isn't at all above assaulting people and dogs with glass shards or fire pokers.
- Meaningful Name: Daniella is the female equivalent of "Daniel", a Biblical Hebrew name. Her faithfulness towards her master Lorenzo suggests that her name is meant to invoke Daniel's faithfulness to God. Alternatively, Daniel is also the name of a fallen angel in the Book of Enoch, which is rather fitting. According to Word of God, she lost her freedom as a girl when she was kidnapped by Lorenzo. She had "fallen from her master's grace" due to her body being infertile.
- Mood-Swinger: After going full-blown Ax-Crazy, there are some places in her area of the castle where she will be completely uninterested in Fiona, having gone back to being an Emotionless Girl. The second you leave such an area, all bets are off.
- Not So Stoic: As Fiona will gladly tell you.
- Ojou Ringlets
- Our Homunculi Are Different: Or so we're led to be believe. She is, in fact, a normal human woman, odd tendencies and tears of blood or not.
- Rage Against the Reflection: Really does not like mirrors, to the point where you can stun her by showing her one and cause her to stand still and scream for a bit. She'll actually headbutt the mirror until it breaks.
- Rei Ayanami Expy: Her seeming lack of emotions, purple hair and extreme deference to the masters of the castle all cement her as this from the moment she appears. Also a rare example of an antagonist fitting this archetype.
- Sanity Has Advantages: Daniella would be very capable of catching Fiona if only for her mental issues. The Clock Tower Wiki lists the disorders she apparently has and how they translate into game terms, like her screaming at mirrors or deciding that "cleaning time" means she can't chase Fiona for awhile.
- Self-Imposed Challenge: Her fire poker acts as this for the player. It makes Daniella permanently enraged, which gives her a charging attack and causes her to scream more often. On the other hand, this makes her less likely to find Fiona when hiding, and she stops caring so much about closing doors.
- Statuesque Stunner: She appears to be very tall and she's very (eerily) beautiful.
- Uncanny Valley Girl: An oddly pale woman who neither smiles nor moves naturally, even before she snaps.
- The Unsmile: When she's not expressionless or Laughing Mad, she's somewhere between this and a Psychotic Smirk.
- Tragic Monster: After finding out more about her, she can garner some sympathy when not actively hunting for your blood. And then the Word of God mentioned above makes her quest for Azoth absolutely pointless!
- Weapon of Choice: A long shard of glass, or a hot fire poker.
- You Gotta Have Blue Hair: Lavender, actually.
The hooded castle keeper, Riccardo is fully intent on making Fiona "his." He usually acts as Mr. Exposition towards Fiona until...
He reveals himself to be one of Lorenzo's many "failed" clones to be bearers of Azoth. Technically, he is Fiona's "uncle" and her father's "brother." His goal is to impregnate Fiona so he can be 'reborn' with Azoth as a means to live forever. He succeeds in the worst ending.
- Attempted Rape: Poor Fiona. Happens in the worst ending, making it confirmed rape.
- Ax-Crazy: He is sadistically cruel to a fault. Best demonstrated in his chase sequences, where every so often he'll break down quietly Laughing Mad if he's particularly hurt Fiona.
- Bald of Evil: Under the hood, he's completely bald.
- The Bad Guy Wins: In Ending D, where he successfully rapes Fiona and impregnates her.
- Cain and Abel: He is the Cain to Ugo's Abel. In-game, Lorenzo mentions that Riccardo has always been "a troublemaker."
- Disney Villain Death: Falls off the Water Tower to his death.
- Evil Laugh: Frequently does hammy laughs to show how much he actually enjoys tormenting Fiona.
- Evil Uncle: He is technically Fiona's uncle.
- Facial Horror: He has deep cracks all over his face.
- Faux Affably Evil: He seems like a nice guy when he tells Fiona that she has inherited Belli Castle and expresses concern when she is about to faint, but he drops all pretense of being kind when Fiona refuses to stay there.
- I Love the Dead: If he kills Fiona, he can be heard raping her corpse during the Game Over screen.
- Idiot Ball: Carries this during his earlier chase sequences. He plans to impregnate Fiona, using her Azoth to be reborn with immortality. Shooting her in the head is very detrimental to his plan.
- Immortality Seeker: The reason why he wants to impregnate Fiona is so that he will be reincarnated as an Azoth-filled clone baby that is eternally young.
- Mad Artist: A minor example. An optional cutscene (at 6:24) reveals him to be a rather good pianist and a sculptor to boot.
- Rapid Aging: As a flawed clone lacking Azoth, his body is aging faster than normal. It's also implied by Fiona's description of his corpse that Lorenzo taking his Azoth has had this effect.
- Rush Boss: His boss battle in a nutshell. He can kill Fiona with one shot. Hewie can take him down with one bite.
- Sadist: Riccardo is seen beating Daniella in an optional cutscene, with the manual implying he enjoys physically abusing her often. During his chase sequences, he is positively relishing in Fiona's terror compared to the other stalkers. To the point he may get carried away and shoot her dead.
- The Starscream: Riccardo despises Lorenzo and has seized the castle from him in his weakened state. It is seen throughout the game that Riccardo is actively trying to find and kill the old man, which is why Lorenzo is in hiding.
- Younger Than They Look: He's only a few years older than Fiona. As a flawed clone lacking Azoth, he's aging rapidly.
An unseen figure who tries to help Fiona as much as he can.
Lorenzo is a genius (if mad) alchemist who made an elixir of life to cheat death. He tried to make clones of himself, all of them failing to produce Azoth except Ugo, Fiona's father. Ugo, against Lorenzo's wishes, married a woman named Ayla and left the castle, eventually fathering Fiona. Fate drew the family back towards Belli Castle, and the car accident sets the events of the game in motion. Lorenzo just wants to kill Fiona for her Azoth.
- And Then What?: It's not clear what he even wants immortality for- his whole life has been spent just on attempts to get it.
- Antiquated Linguistics: Calls Hewie a "meddlesome cur" when he attacks him. As he's in his young form at the time, it might be a subtle way to remind the audience that he's an immortal being from an earlier time.
- Ax-Crazy: If he wasn't insane to begin with, he brings it Up to Eleven after resurrecting from being burned alive.
- Big Bad: Lorenzo is behind virtually everything bad that happens to Fiona throughout the entire game - the reason the bastard's after her to begin with is because she was fathered by his only successful clone against his wishes. Disregarding Debilitas, every stalker after Fiona is his creation and has their sights on her because of the Azoth in her body.
- Bishounen Line: Goes through this after his old body is crushed.
- Cruel and Unusual Death: Dropped into a pit of lava. This takes several minutes to kill him.
- Beforehand, he is also flattened by a rock crusher.
- Devour the Dragon: A hidden cutscene after Riccardo's death shows Lorenzo dragging himself over to his body and sucking out Riccardo's remaining Azoth. This is why Lorenzo rejuvenates later; if that amount of Azoth was able to turn a decrepit old man into a powerful young sorcerer, it's no surprise that he wants the Azoth spring inside Fiona's body.
- Dirty Old Man: He watches Fiona change through a peephole, and he also set up cameras throughout the castle to keep an eye on her.
- Evil Redhead: When Lorenzo regains his youth, his hair is red.
- Expy: His old form looks remarkably like Ozwell E. Spencer, while his young form looks like a red-haired Vergil.
- Hot Guys Are Bastards: In his young form.
- Implacable Man: He survives getting blown up, Squashed Flat by a rock-crushing machine, and getting burned alive. He finally dies from his severe burns.
- Infernal Retaliation: After being defeated in his young form, he gets back up, while on fire (for the record, he's beaten by dropping him into a pit of lava). He then spends the next few minutes making a frenzied last-ditch effort to nab Fiona, killing her instantly if he manages to catch her. Fiona can't really do much except get the hell out of the castle and let Lorenzo burn himself out.
- Pyrrhic Villainy: Even if he does succeed in spending his last ounce of strength catching and killing Fiona as he burns to death, and gains immortality upon extracting her Azoth, he would barely benefit from it as his body would still continue to burn from lava fire.
- Life Drinker: How he manages to stay alive. Used in conjunction with Devour the Dragon, as detailed above.
- Longevity Treatment: He uses Azoth to regain his youth and power.
- Mad Scientist: He created Ugo and Riccardo, after all.
- Meaningful Name: Lorenzo is Italian for "someone from Laurentum." This ancient city's name may have been derived from the Latin word "laurus", which means laurel, "a symbol of wisdom and accomplishment." These terms likely relate to Lorenzo's ancestry and his own accomplishments as a master alchemist.
- Mysterious Informant: He leaves a lot of notes for Fiona to find.
- Oh, Crap!: Goes through this in Ending C, where he realizes that Fiona has escaped from the castle. He wheels after her while shouting her name in desperation.
- Really 700 Years Old: Lorenzo has been alive since the 1860's.
- Sadist: Though he pretends to care about Fiona's well-being, this turns out to be a lie. He temporarily locks Fiona in a room just to watch her struggle and despair, and when stalking her in his young form, he will frequently stop to laugh and sarcastically applaud Fiona's efforts.
- Walking Spoiler: As one can see, it's very hard to say much about Lorenzo without giving a lot of the plot away.
