Heaven's Feel is noteworthy for being the darkest route of Fate/Stay Night and one of the darkest parts of the Fate series as the whole. Remember the scary parts of the route? Some of them are now vividly animated.
Per wiki policy, all spoilers will be unmarked.
Presage Flower
- Shirou's flashback to the disaster of the Fourth War, with him as a child standing in the midst of fire staring at the Holy Grail itself. It suddenly appears just as he over hears Taiga and Sakura discuss dinner out. What's especially eerie about is how so... resigned Shirou appears to it.
- Shirou's second dream of the disaster, this time with him watching his child self. And lllya is there, pulling at his self and urging him to summon his servant soon or else he dies. With a cheerful stare to help.
- Once again, lllya and Berserker attacks Shirou, Rin, and Saber. The child also encourages Berserker to violate Saber after beheading her. Also, Berserker striking Shirou then the latter tries Taking the Bullet for Saber. As Shirou rolls across the ground, you can see his intestines fall out.
- The birth of True Assassin... who bursts from the regular Assassin's chest while cackling like a madman.
- The start of it was creepy by itself. First Assassin drops his sword down the steps, then he starts bleeding from the mouth and just drops on his back before...
- True Assassin's initial mannerisms. He becomes more coherent later on, but early after his release/birth, he starts out with janky movement with the sound of cracking bones, incomplete speech stuttering, and was prone to growling and unhinged shrieking.
- Souichirou and Caster's deaths. After puzzling together that her Assassin fell, she finds True Assassin in the temple, atop a butchered-yet-still-alive Souichirou. He uses Souichirou as a hostage to make Caster release her control over him with Rule Breaker, then stabs her through the neck and finishes off Souichirou with a knife throw. It's disturbingly more realistic than most manners of death in the series.
- After True Assassin leaves, something drags Caster's body out of the temple...
- Zabaniya, True Assassin's Noble Phantasm at work. His elongated arm, him crushing Lancer's heart, and then him ripping it out to drink its' blood and eat it while the Shadow has the rest of Lancer's body.
- For that matter, Lancer's death. Even aside from the manner of his death, his expression after Assassin crushes his heart remains unchanged. Even when blood drips from his mouth and the Shadow pulls him into the water to devour his body, the only hint of him still being alive are his last thoughts.
- Zouken appears before the heroes, revealed to be using Caster's corpse as a puppet Servant. And it hasn't been kept in good condition. Rule Breaker is still embedded in her chest, the gaping wound in her neck left by Assassin is still present, and you can see Zouken's worms popping from her mouth. As she casts a giant fireball, her left arm falls off and starts to rot.
Lost Butterfly
- The opening scene. Shirou's desperate search for Saber from the end of Presage Flower is reimagined into a nightmare. Instead of meeting with Sakura, Shirou finds Saber in the distance within the mist... and a bunch of tendrils rising from the water, appearing to consume her. The mist blows away to reveal the Shadow, which suddenly appears in front of Shirou and starts to... spasm, flailing its tendrils around and popping out black arms before devouring Shirou, who can only shake in horror. Only an imprint of his body is left in the snow.
- The Shadow’s shrieking just before attacking Shirou. It's less of a typical animalistic sound or a distorted scream. It’s closest to the sound of a handful of voices screaming in agony.
- It's less terrifying than... everything else in the trilogy, but the casual way that lllya stating that she could kill Shirou in an instant without Saber around during their talk in the playground is notable.
- The seemingly whimsical and happy Disney Acid Sequence in Lost Butterfly. Sakura falls bedridden and the film suddenly switches tone and artistic style to resemble a playful and whimsical "Alice In Wonderland" cartoon, with Sakura in a pretty white dress skipping through a magical town filled with dancing teddy bears and stuffed animals. Even the music is cheerful and heartwarming, which is quite jarring considering the bloody darkness that preceded the previous two films. Thing only start to go wrong when Sakura danced over a bridge, under which several of the stuffed toys floated down the town's river, as four angry pink bears dance around the happy girl; Sakura flicks them playfully across the head with her finger, causing them to literally explode in a cloud of confetti and candy. Sakura does so again, and again, and again to every animal friend she bumps into... until the town is literally raining with colorful candy. She picks one up, unwraps it and starts chewing... and the Camera suddenly smash-cuts to the realistic-style of the rest of the film in a dark alley, with Gilgamesh sneering "You should have died while we could still kill you" straight at the camera. Little did Sakura (also now in realistic style) know, the orange "candy" she was chewing on was a human finger. The ravenous Grail howling for life-energy in her uterus compelled her to go on a murderous rampage across Fuyuki, eating people alive. Sakura's heartwarming and whimsical fantasy of adorable animal friends was her mind's way of coping with, instead of reconciling with, the horrifying reality that she was literally tearing people into pieces (candy) and gobbling them down her throat, throwing remains too large to swallow into Fuyuki's river. Made worse by the fact that throughout this heartwarming dream-sequence, Sakura's voice actress narrated an adorable children's poem/song with lyrics that amounted to "My tummy was a rumbly~ I hit the bears and boomy~ and I gobbled up the candy~ then my tummy was not rumbly~"
- The death of Gilgamesh immediately following this. Sakura seems taken over by the Shadow, glitching to her feet as Gil fires his treasures at her. However, he’s surprised when the weapons simply pass through her aura and become corrupted. He momentarily bears an expression of dawning comprehension... and then it cuts to a close-up of Sakura’s mouth, as she mimes taking a bite out of something. There’s a horrible sound as she keeps chewing, the camera pans out, and all that’s left of the King of Heroes is half of his leg.
- The Shadow's expanding influence, albeit brief, it is a terrifying sight to behold, as the black mud expands all across Shinto and consume everyone it come across, leaving a black puddle behind. It was shown to be able to phase through vehicles, causing the poor driver's vehicle to crash, then ate another pedestrian almost instantly right when his friend looked away. Even pets are not immune, as the Shadow also ate all the fishes in the aquarium as the Ominous Visual Glitch takes effect.
- The Lost Butterfly drama CD reveals that Shinji's soul was absorbed by Dark Sakura after his death. He lost his mind completely, is tormented by his worst memories and fears forever and is deluding himself into thinking he won the war to cope."Aaah, shit. I can’t remember too well. But...I’m here, so that must mean I won, right? Haha, that’s right. I can’t lose, that’s impossible! ....I guess the sun’s gone down. It’s gotten dark in here. I can’t see you anymore. Hey... would you mind turning on the lights? [...] Ah... You see......It’s pitch black in here."
- Every time the unborn Eldritch Abomination in the Greater Grail is shown, with its four bulging eyes glaring at what happens below it, betraying a sliver of emotion each time.
Spring Song
- The origin of Angra Mainyu aka The Shadow. He was once an ordinary person who was chosen by his fellow man to be the one to bear all the sins of the world, was tortured, and then killed. Despite being the weakest Servant, he still managed to taint the Grail for the Third, Fourth, and Fifth wars. The fact that humanity literally was able to create a man-made god of evil is enough to scare most.
- When Shirou Traces Heracles' Nine Lives, there is a quick slideshow of his Twelve Labours. The eleventh labour, the Golden Apples of the Hesperides, shows him facing off against Ladon, a gigantic wyrm with a head that tears opens to reveal a dark abyss with several glowing eyes
◊. While the image is only on-screen for half a second, it really makes you wonder how monstrous the rest of the Greek monsters were. - When Shirou traces the Jewel Sword, we get to see the moment when the Fuyuki Holy Grail Wars began, where each of the Three Founding Families cite their contributions to make the ritual for the Third Magic possible. The Tohsakas provide the land and leylines and are responsible for summoning the Servants. The Makiris, nowadays Matous, formed the Servant class system and Command Seals. The Einzberns meanwhile provided the alchemy to create it and prepared the vessel for the Grail. Sounds normal right? It is revealed in here that Justeaze, the Einzbern matriarch had to lie on the central altar and get brutally crushed flat to spread her magic circuits over the surroundings in order to ensure that the Grail would enact her will for the Grail Wars. And that, was how the Greater Grail is made.
- Sakura tearing out the worm in her chest, which is revealed to be Zouken Matou's true body. Just how long did that girl have that worm inside of her?
- When Saber is defeated she melts into the shadow, unlike Berserker who disappeared in motes of light.
- When Shirou debates about having to project one last time to take down Angra Mainyu, he gets flashes of his body being skewered from the inside out by swords. One is even coming out of his eye in the final flash.
