Berserker (バーサーカー, Bāsākā?) is a Berserker-class Servant summoned by Karin "After" the Holy Grail War in Fate/Requiem. She is also summoned by Ritsuka Fujimaru in the Grand Orders of Fate/Grand Order.
The demoness from the legends. According to the legends, she was killed by Taira no Koremochi during the Heian period, on the mountain of Togakushi. She was also said to be the leader of a group of bandits who opposed the Imperial Court, or a lady who taught villagers how to read and write and healed their illnesses. Her story was presented extensively in the form of a noh, jōruri and kabuki performance, the "Momijigari".
Her name in her childhood was "Kureha" which was changed to "Kōyō" when she went to the capital. By nature she was a beauty overflowing with wisdom who drew the attention of many people; she was also skilled with the koto which earned her the notice of Minamoto no Tsunemoto's wife. She was favoured by Tsunemoto right away, but she received the capital punishment when she was suspected of putting a deadly curse on the shogun's wife. However, since she was already carrying Tsunemoto's child, instead, she was banished to the province of Shinano. Kōyō, who was welcomed by the villagers of Minase (later Kinasa), eventually became feared as the "kijyō (oni woman)" who led the bandits of the surrounding areas. The military commander Taira no Koremochi who was tasked with her subjugation met Kōyō in the mountains by chance, but it turned into a desperate battle. Koremochi, who prayed to the gods and Buddha, was gifted with a spirit sword capable of conquering demons and, dressed as a traveling priest, challenged Kōyō by himself and finally defeated her.
Kōyō, who was said to be a gift from the Demon King of the Sixth Heaven in response to the prayers of a couple who weren't blessed with a child, possessed the qualities of witchcraft from a young age. Mount Togakushi, located in the province of Shinano where she was banished to, was a mountain of asceticism where ascetics founded a temple after they received a vision from Kuzuryūshin. In addition, Mount Iizuna, which was adjacent to Mount Togakushi, was a land of witchcraft and the supernatural that was popular with the worshippers of the tengu. With this place as the backdrop, Kōyō made another kijyō, "oni lady", her follower who was a remnant of the Imperial Court hating Taira no Masakado's group and was known for her superhuman leg strength.
Berserker cannot speak, and communicates with her Master Karin through telepathy. Even then Karin does not actually hear Berserker's thoughts as words, but rather as feelings. Erice Utsumi has an app which tries to analyze Berserker's body movements and put it into words, though it is not very precise.
In her humanoid forms in Fate/Grand Order she is capable of speech, but is still mute in her dinosaur form.
Berserker's dinosaur form was inspired by a great skeleton of a dragon god of the mountains which impressed her; perhaps in truth it was a dinosaur fossil.
Berserker is a sweet and gentle Servant despite being a Berserker. She often watches out for Voyager.
Koyo has watched over Karin since she was born, but did not manifest physically until Karin was 9 years old because Karin's parents hate Servants and do not allow them to be summoned in their home. Koyo first manifested when Karin was kidnapped by Louis XVII. They communicated via telepathy before then.
Contrary to her class, Koyo is a gentle Servant well versed in healing magecraft. Berserker's Noble Phantasm is Momijigari.
Shapeshift (Dinosaur): C From a court lady of high standing, she transforms into the form of a terrifying kijyō. Furthermore, because she desired the Madness Enhancement, she came to possess the massive body of a dragon.
Kuzuryū's Flash of Lightning: A: A prayer and kagura revering Kuzuryūshin who is a fierce oni and also a water god. It appeases and controls the fury of all things in heaven.
Lifeline: B: An incantation of Iizuna Gongen's protection that drives away sickness and brings about a long life.

 Tsukihime Dokuhon PlusPeriod - TSUKIHIME Dictionary: Tohno Akiha [Person's name], p.185
Akiha Tohno [Person's name]
One of the heroines in Tsukihime. Shiki's younger sister, and the Tohno family's heir.
She has long black hair and a dignified posture, firm speech, and an unendearing personality. On top of that, her love of strict discipline can make her somewhat hard to get along with.
Perhaps it's because she doesn't think much of the way Shiki lived doing whatever he pleased for eight years, but she lashes out at him every chance she gets. Though she is basically straightforward and honest at her core, she is also unyielding and hates losing, so her true personality rarely gets a chance to shine.
She was one of the people involved in the accident eight years ago, after which her dormant Tohno blood was awakened. Though she would have been able to suppress it if she only had to worry about herself, she was carrying the burden of two people. As a result, she started being attacked by seizures nearly every night, and at Kohaku's suggestion began drinking blood to maintain her body.
…Of course, it was all just a scheme to push Akiha closer to her Tohno nature. Probably, even Akiha herself was aware of it on some level.
In one of the routes, she ended up inverting and demonstrating her power to its fullest extent. That dreadful form, with its fluttering vermilion hair, is probably capable of exceeding even a rampaging Arcueid.
Long ago, in the Tohno's country, there lived a female oni named Momiji. Though she is not their ancestor, maybe you could consider her the origin of Akiha?
Incidentally, Akiha is the character with the greatest number of individual sprites. It actually made the art director break down in tears. Not only were there uniform sprites and casual sprites, but sprites for Akiha when she was inverted as well.
Also, by some strange twist of fate, her roommate at school actually had the last name "Tsukihime".
She was the only heroine in Tsukihime that didn't get a happy ending, which apparently made a lot of fans mad. We got a ton of hate mail demanding that we do something about it, hahaha. I guess it worked, though, since we ended up writing a sequel to Akiha's ending for Kagetsu Tohya.
She is the student council vice president at the Asagami Academy for Girls, and seems to be quite popular.
…Of course, that popularity stems from equal parts reverence and terror.
In Kagetsu Tohya, the power relationship between her and Kohaku began to change, and in Melty Blood she was the victim of Kohaku's cheerful treachery. Also, though the Akiha in Melty Blood is pretty… energetic, she's normally a little more graceful than that.
She totally lacks the pride and thin skin characteristic of the super-rich, but her sense for how to use money is still grossly out of sync with normal people's.
When she told Sion to "rest a bit", in Akiha's head "a bit" meant either until Sion herself was sick of it, or until she was dead. It seems she's the type of person who's cold to strangers, but excessively soft toward those who have earned her favor. Ah, so that's why you let Kohaku toy with you as she pleases, Lady Akiha!
