There are eight servants in "Fate/stay night", but this time we will focus on Caster, a magician servant. Caster's exploits are vividly depicted in "Fate/stay night [Unlimited Blade Works]", known as the Rin route, and you can learn various information about Caster, such as her past. We will introduce Caster's true name and character image, which are not detailed in other routes, so please check it out until the end.
Caster who appears as a magician servant
Caster, a servant who appears in "Fate/stay night", cooperates with Katsuragi Souichirou, who lives in Ryutoji Temple, and participates in the Holy Grail War. She appears as a female heroic spirit dressed in a robe, and although she has not mastered magic, she has the power to calmly use super-high level magic that is close to magic, and is a servant who can achieve overwhelming results in human battles. First, we will give a brief overview of Caster in "Fate/stay night", so please check it out.
Saved by Kuzuki Souichirou and avoided annihilation
Caster, who appears in "Fate/stay night", did not make a master contract with Kuzuki Souichirou from the beginning, and had a different original master. However, he decided that he was not compatible with the master he summoned, and killed him after wasting his command spells with a trivial command. After that, Caster was attacked by Lancer, but he managed to escape to the vicinity of Ryutoji Temple, where the Holy Grail sleeps and has an excellent spiritual lineage. However, Caster, who can no longer receive magical power from his Master, is on the verge of extinction, when he is accidentally saved by Kuzuki Souichirou. From then on, Caster uses Ryutoji Temple as his own shrine, siphoning life force from people in the town to turn it into his own magical power and build up his strength.
Beyond the relationship of Master and Servant?
After being attacked by Lancer, Caster was on the verge of extinction, but luckily he met Kuzuki Souichirou and made a contract with his new Master.
Caster killed the Master she summoned of her own volition, but she was indebted to Kuzuki Souichirou for saving her from danger, and fell in love with his devotion. Caster was once celebrated as a "witch" in her lifetime, and even so, she may have been influenced by Kuzuki Souichirou's sincere concern for her, seeing her as a woman and partner.
Caster's real name is Medea the Traitorous Witch
Caster, who appears in "Fate/stay night," has a master contract with Kuzuki Souichirou, who is not a magician in the story, and replenishes her magical powers with the magic she uses.
Her real name is Medea the Traitorous Witch from Greek mythology, and since she has been treated as a witch since the age of mythology, her skills not only surpass those of modern wizards, but are also among the best in the world. In the main story, Caster is called a witch by Archer, but in reality, she never used the magic that caused her to be called a witch while she was alive, nor did she break any of the taboos. Therefore, she swears revenge on those who made her into a "witch" and becomes a Heroic Spirit, but in reality, she understands that using magic on those people is pointless, so she only deals with minor curses that cause them to suffer from accidental desires and returning disasters.
Weakest of all Servants in terms of attack?
Caster, a magician servant, fights in the Holy Grail War with magic and sorcery, but since other servants have anti-magic powers, he has no chance of winning in battle.
However, he is skilled in strategy and intelligence, and his fighting style involves using various strategies before and after battle to gain the upper hand. In addition, since he is a far superior magician in human-to-human combat, Caster will certainly have an overwhelming advantage if he is to face a Master in a one-on-one battle. Therefore, in "Fate/stay night", unusual combinations such as Caster vs. Master and Kuzuki Souichirou vs. Servant are realized, and there are also scenes where battles are won through strategy.
"Rule Breaker" that resets all magic
The Noble Phantasm possessed by Caster in "Fate/stay night" is the anti-magic Noble Phantasm "Rule Breaker", which can reset all magical creations. It can be used for various purposes, and in "Fate/stay night [Unlimited Blade Works]", it nullified the contract between Emiya Shirou and Saber, and even had Archer under its control. It is also possible to take control of the contract through the Command Spells, and under the rules of the Holy Grail War, it can be said to be a Noble Phantasm that can be a one-hit kill weapon.
Summon Assassin by taking the rights away from another Master
Using the power of the Noble Phantasm "All the Charms That Should Be Broken" that Caster possesses, he can take Servants from other Masters, and in the story, he had Saber and Archer under his control. Furthermore, Caster places Assassins he has stolen from other Masters in Ryuto Temple, which serves as his own temple, and controls them as their master.
The Assassins are bound to Caster's orders and are unable to leave Ryuto Temple due to the barrier that has been put in place, but they demonstrate their overwhelming power in confronting Saber. In this way, if Caster wanted to, he could have controlled all of the summoned Servants and easily won the Holy Grail War.
What is Caster's position in each route?
Caster in "Fate/stay night" is based in Ryutoji Temple, and absorbs life force from people in the town to store magical power. Although she has a hard time fighting Servants, she can attack Masters from an overwhelmingly advantageous position. What position does Caster have in each story of "Fate/stay night", and how did she act and meet her end?
Saber Route
In the Saber route, there are fewer scenes in which Caster appears, and it seems that she was already fighting other Servants when she appeared. Although he still killed his master with his own hands, his new master, Kuzuki Souichiro, has not yet appeared. Caster appears before Saber and the others, but Gilgamesh appears and brutally murders Caster.
Rin Route
In the Rin route, which has many scenes with Caster, he steals Saber from Emiya Shirou and then recruits Archer to use him as a pawn. As a result, Emiya Shirou and Tohsaka Rin temporarily lose their servants, but during the operation to recapture Saber, Caster is betrayed by Archer. The battles of Caster vs. Tohsaka Rin and Kuzuki Souichiro vs. Emiya Shirou were clearly favorable for Caster's camp, but in the end he is defeated and falls along with Kuzuki Souichiro. Also, when he is recruiting Archer, he is also recruiting Emiya Shirou at the same time, so Caster may have sensed something between the two from that point on.
Sakura Route
In the Sakura Route, Caster also makes fewer appearances. When Katsuragi Souichirou is killed by True Assassin, Caster tries to use "All the Charms That Should Be Broken" to save him. However, Saber appears at the same time, and she mistakenly thinks that Caster has taken her Master, and cuts him down on the spot. However, Shirou Emiya later hears that Caster, whom he thought he had defeated, is still active, but he discovers that he has been turned into a puppet by Zouken Matou.
Introducing Caster! Summary
We have introduced Caster, who appears in "Fate/stay night", but in the main story, he appears in few scenes other than the Rin route, and does not survive to the end as the servant is evaluated. However, in "Fate/stay night [Unlimited Blade Works]", he has Saber and Archer under his control and has progressed to the point of tormenting Emiya Shirou and his friends, so it can be said that he is a difficult opponent in the development of the strategy that is laid out. He has a unique fighting style in battle, and since his master, Kuzuki Souichirou, is in charge of the front line, you can enjoy a different kind of Holy Grail War battle.
