Sakura Matou (間桐 桜, Matō Sakura) is the Master of Rider in the Fifth Holy Grail War, though, as she dislikes conflict, her brother Shinji acts as Rider's master in the Fate and Unlimited Blade Works routes. Originally the second daughter of Tokiomi and Aoi Tohsaka, and the younger sister of Rin, she was adopted into the Matou family to act as the successor of their magecraft, as Shinji lacked any magical ability.
Abused and mistreated by both her grandfather and brother, she was forcibly implanted with the Matou family's Crest Worms, which have assimilated into her body and magic circuits. These act as her Magic Crest, constantly feeding on her energy when active and causing extreme pain. She is also turned into an incomplete, secondary Lesser Grail, the Black Grail (黒の聖杯, Kuro no Seihai). Going inactive throughout most of Fate/stay night, she becomes active as a Lesser Grail in Heaven's Feel due to Shirou's actions and Kirei's machinations.
Powers and Stats

Name: Sakura Matou
Origin: Fate/stay night
Age: 16 years old
Classification: Magus, the Black Grail
Powers and Abilities: Magecraft, Darkness Manipulation, Absorption (She can take in and absorb others with the Black Shadow, which also breaks organic matter down into magical energy with a touch), can absorb others into a completely separate dimension of darkness, Mind Manipulation (The Black Shadow destroys the minds of those it affects, and can corrupt Servants and distort their mentality), Soul Manipulation (A Lesser Grail created to absorb and collect souls, which she burns for magical energy), Teleportation (Can travel through shadows to travel between two points nearly instantaneously) Summoning (Can summon Shadow Giants), the Black Shadow is intangible, incorporeal, and possibly immortal (Type 5; Shirou notes that it may not even have a concept of death), Resistance to Magic (All magi have basic resistance to magical effects), Regeneration (Mid; regenerated from Gilgamesh destroying everything below her stomach)
Attack Potency: Wall level (Despite her virtually limitless mana, her output is only equal to Rin's), Unknown with the Black Shadow (Does not rely on physical power, instead absorbing its foes and destroying their minds. Said to be capable of overwhelming any Servant summoned by the Grail, instantly shattered Lancer's runic barrier, which can block great Noble Phantasms, overcame and absorbed Berserker and even Gilgamesh, but couldn't pierce Shirou's skin when he was transforming into swords), Mountain level with Shadow Giants (Their power matches a Noble Phantasm, and Gáe Bolg: Soaring Spear that Strikes with Death is said to be average in terms of power for a Noble Phantasm). Ignores conventional durability with the Black Shadow (It breaks down and absorbs whatever it touches, consuming souls and destroying minds).
Lifting Strength: Unknown
Striking Strength: Human Class, Unknown with the Black Shadow (Shattered Lancer's runic barrier but couldn't harm Shirou), Mountain Class with Shadow Giants (Comparable to a Noble Phantasm, can effortlessly kill Servants like True Assassin).

Stamina: Virtually limitless. She has almost a trillion units of magical energy, as compared to the 25 - 100 for normal magi.
Range: Melee range, further with magecraft, Tens of Meters with the Black Shadow and Shadow Giants (The Black Shadow can swallow an area of fifty meters all at once)
Standard Equipment: Nothing notable.
Intelligence: Average. Sakura is a relatively ordinary high school girl, and though she is a magus, she lacks much knowledge on magecraft or combat.
Weaknesses: Sakura has no combat experience and is a very poor magus. Her crest worms are constantly feeding on her magical energy, so without the Grail she almost never has any mana to cast spells. The Grail gradually corrupts her mind and will overwrite her souls with the data of Servants as they die and are absorbed. As Dark Sakura, she is incredibly overconfident and sadistic.
Notable Attacks / Techniques:
Magecraft: While Sakura's potential as a magus is comparable to Rin's, the harsh, torturous process of becoming a Matou magus, and Zouken's uncaring actions have squandered it. She has an affinity of Hollow, or Imaginary Numbers, but she is forced to utilize the Matou's traditional element of Water instead. Sakura has little knowledge on magecraft, lacking any formal education in its use or in combat. When her Magic Crest (the Crest Worms assimilated into her body) is active, her energy is constantly drained to the point that she can't even cast spells.
Under duress, and when supported by her connection to the Grail, she can use magecraft. She can use the Matou magecraft of absorption to drain the magical energy of others, and her Hollow affinity makes the magecraft she casts with it extremely effective against spiritual beings. By combining both, and with the support of the Tainted Grail, she can easily affect physical beings and imprison others in a separate dimension made of shadows.
- Shadow Giants: Simple familiars made out of Sakura's Hollow element. Normally, they are incredibly small, small enough to fit in her hands, but with the augmented power provided to her by the Holy Grail, they are immense and possess power comparable to that of an average Noble Phantasm, making them more than a match for most Servants, and she can summon many at once.
The Black Grail: Sakura has been implanted with the shards of the destroyed Grail by Zouken, transforming her into an incomplete, secondary Lesser Grail, the Black Grail. These shards have been combined with the Crest Worms inside of her, allowing her to act normally under normal conditions. Initially just an experiment in creating something to collect souls, one that wasn't meant to see any real use, the events of Heaven's Feel allow her to become active. She adapts quickly to her new role, capable of remaining active even as she absorbs more and more Servants.
The contents of the Grail, a Black Shadow, come into the world and acts as Sakura's shadow, roaming Fuyuki at night to drain magical energy from others, ultimately consuming them entirely. It is a Cursed Boundary Layer, something incapable of taking shape normally, but given form by Sakura's negative emotions, and pursues those she hates. It is intangible and incorporeal, incapable of being affected by conventional attacks, and potentially lacks even a concept of death. Its touch corrodes all it comes into contact with, carrying on the curse of All the World's Evil, dissolving organic matter and breaking it down into magical energy. It can spread out over an area like mud, or absorb all the energy in an area to explode and swallow everything around it.
The Servants that come into contact with the Shadow are instantly affected, and are incapable of even opposing it. They rot everywhere it touches them, losing sensation as their body ceases to exist and is absorbed into the Shadow. While Heroic Spirits are greatly affected and lose consciousness quickly if not instantly, Servants that are closer to it in nature (such as Antiheroes) can resist its effects somewhat, but their energy is still drained.
When Sakura rejects Zouken's control and becomes Dark Sakura, a monstrous distortion of her normal self, the Shadow takes the form of the Command Spell that drapes her body. She is corrupted by All the World's Evil, losing her reasoning and causing her emotions to spiral out of control. She is unpredictable and violent, and despite her overwhelming power, she is still unused to combat and quite unstable. Her power is such that she could turn into a threat that would require the Counter Force itself to step in, and using All the World's Evil, she could drown the world in a tainted mud and eradicate humanity.
