If we were to say which Servant was the most unlucky in this Holy Grail War, it would definitely not be Lancer Cu Chulainn, who was forced to change bosses twice, but Caster Medea.

Medea is known as the witch of betrayal in mythology, but the reason why her brain was filled with water was entirely a trick of the gods. Otherwise, how could she have loved the hero Jason so desperately and then done such horrible things as dismembering his body?

In the calculations and love of the gods, she changed from the simple and romantic Princess Kolsky into a cold, cruel and unscrupulous witch of betrayal. Even though the initial reason was absurd, betrayal eventually became the main theme of the life of this princess.

The Lord of Sorcerer who summoned her did not trust her from the beginning and even used Command Spells to restrict Medea.

But the protector did not consider that the one who cursed Medea was a god. Conversely, only a god could use curses to make her obey orders.

Most modern magicians regard Heroic Spirits as familiars, so his final outcome is predictable. He was tricked by Medea into using up all three Command Spells, and was instantly killed.

But Medea also made a mistake. The lord who summoned her planned to sell her to the priest of the Cathedral Church, Kotomine Kirei.

Kotomine Kirei did not refuse to add another Servant for himself. After all, there were so many children who provided magic in the basement. He could even supply Gilgamesh with magic power. With Caster, victory in the Fifth Holy Grail War would be just around the corner.

After all the calculations came together, Medea killed her lord. Coincidentally, Kotomine Kirei came with Cu Chulainn, who he had just captured, to complete the transaction. As a result, Medea, who was without a lord, was severely injured by Cu Chulainn and could only escape.

Cu Chulainn was forced to separate from his lord Bazet, and was originally unhappy about it. But it turned out that there were not only lords who stole servants, but also servants who killed lords. He really learned a lot.

This distraction caused Medea to escape.

…Then she had the misfortune to run into Matou Dirty Inkstone.

At that time, Kirisakura summoned Rider Oberon, who claimed that he was the Fairy King from "A Midsummer Night's Dream" and had no offensive power. Matou Ruoyan thought that Oberon was a useless Servant, so he planned to go out and steal a Servant himself.

When he met the lone Medea, Jiantou Ranyan was overjoyed and naturally chased after her immediately.

As the saying goes, a dragon wandering in the shallows is often teased by a shrimp. Medea has no magic power, so she can’t use any of her tricks and can only fight and retreat.

Matou Ruoyan didn't want to attract attention, nor did he want Medea to recklessly devour ordinary people around her to replenish her magic power, so he tried his best to lead Medea to a sparsely populated mountain town.

Once Caster's magic power is exhausted, Matou Kuran can summon a new Caster through Medea.

As a result, Matou Ranyan didn't expect that there was a half-dead Bazette in the haunted mansion.

Medea, who was being chased all the way and was about to die, met Bathet, who never died because he wanted me to participate in the Holy Grail War. They fell in love with each other immediately.

When we look into each other's eyes, we both know we are doomed, so let's stop talking nonsense.

——I will be the Lord and you will be the Servant. I swear by the Command Seals that I will not control you, and you swear by the Command Seals that you will not harm me. The remaining Command Seal will serve as a contractual connection, and then we will join forces.

Although Bazette's Command Seals were stolen, as a disciple of Hecate, the goddess of magic, it was easy for Medea to copy a Command Seal.

Even Medea herself can make the Holy Grail. After all, the Holy Grail is just a super-powerful magic amplifier. For her, a magician from the Age of Gods, it is a piece of cake.

Only the Holy Grail that descends in the Great Holy Grail ritual initiated by the three families, which has accumulated magical power for two hundred years, has the function of granting wishes, so Medea will respond to the summons.

With the support of the Lord of War, Medea no longer had to worry about running out of magic power, so she used her ultimate move. She rudely devoured the lives around her, then opened her magic dress robe, used high-speed divine words, and released more than a dozen magic beams in one second, grinding Matou, who was chasing her, into a pulp.

At that time, this wave of magic power was noticed by Izawa Sugi who was near Ryudo Temple, but Izawa Sugi and Tosaka Rin had just escaped and did not go to check the situation.

Matou Ranyan retreated in hatred and went back to the insect nest of Matou's family to recuperate. Before he could completely recover from his injuries, Tosaka Rin brought Izawa Sugi and attacked Matou's family with great momentum, and then... nothing happened.

The dirty inkstone of Matou is finished.

On the other hand, although Medea defeated Matou Ruoyan, Bazette was almost finished.

So Medea did not pursue Matou Ruoyan, but used the Phantom Mansion as a base and began to build a magic workshop, absorbing the vitality of the surrounding residents to help Bazette recover.

Bathet herself did not approve of Medea's methods, but Medea was helping her restore her magic and life, and she had no qualifications or position to condemn Medea, so she gave her bottom line.

"When you absorb the life force, please be sure to spare the lives of ordinary people."

This is why most of the residents of Miyama Town are in a coma, rather than all of them are dead.

Bazet's left hand was cut off, and Medea used magic to make a ceremonial device, a bone hand based on the bones of a dragon tooth soldier, with various mechanisms and tools built on it. Bazet finally recovered some of his fighting power.

Medea finally found the time and energy to build her own position and defensive magic, but just as she set up the framework, Tosaka Rin and Emiya Shirou showed up with their servants.

Since Izeshan had been outside trying to steal the control of the defensive magic formation, Medea could only devote most of her energy to fighting with Izeshan, and use the remaining energy to cast various auxiliary magic on Bazette.

Since there was no one controlling the system, Tosaka Rin easily smashed all the Dragon Fang Soldiers that were blocking the way into pieces. She looked at the incessant banging sounds coming from above, then looked at the stairwell that had been completely blocked, and a sneer appeared at the corner of her lips.

Tosaka Rin turned around and ran to the window. She pushed the window open, propped it up with one hand, and stood on the windowsill. She held her breath and concentrated, an ice-blue magic circuit flashed through her arm, and then she suddenly jumped up and grabbed the windowsill above the window with one hand.

The next second, Tosaka Rin suddenly exerted force, her body spun in mid-air, and landed easily on the beam above the window.

As for western-style houses, there are always various decorative patterns on the windows and exterior walls. Tosaka Rin grasped the surface of the wall easily like a gecko, and did another somersault, her body floating in the air, her legs straight and exerting force.

Crackling——

Tosaka Rin was like a cannonball or a dart. She kicked the window directly and rushed into the room on the second floor from mid-air!

"Tosaka! Watch out!!"

Emiya Shirou yelled and threw the stick in his hand.

It turns out that Tosaka Rin was climbing the wall outside. As the owner of the workshop, Caster Medea knew about it and she had already summoned a huge dragon-fang soldier to wait by the window.

Tosaka Rin was not afraid. The moment she rushed in, she moved her fingers slightly, and several tiny gems scattered around her body, forming a protective formation. At the same time, she adjusted her body as much as possible. Her two slender legs were like sharp knives, slightly shifting the direction of attack, and facing the machete swung down by the Dragon Fang Soldier.

Snap——

The magic shield in front of Tosaka Rin was shattered by Medea's light cannon, but this second of shielding also bought the girl a chance to turn things around.

She kicked the huge dragon-tooth soldier to pieces, and the moment it landed, the shattered gemstones turned into ropes, tightly entangling Medea who had revealed herself to attack her.

Tosaka Rin exerted force with her feet, kicked the ground hard, and put one hand into a fist at her waist. The huge force was transmitted from her waist and abdomen to her arms, and then to her fists.

"Eight Extreme Fists! Bang!"

Bang--

The huge force rushed directly to Medea's chest, and she spat out a mouthful of blood.

Tosaka Rin, who had the upper hand, kept punching, first with a left hook, then a straight punch from bottom to top, and finally a heavy punch to the face. The punches were so fast and fierce that they almost broke Medea's body!

Tosaka Rin clicked her tongue.

The magic outfit on this woman blocks most of the power, this set can't kill Caster!

Shirou Emiya, who was about to rush over to help, suddenly felt weak under his feet and his expression became extremely strange.

Bathet tried to rush over to help several times, but was blocked on the other side by the experienced Arthur.

When Tosaka Rin's attack came to an end, Arthur shook his sword and rushed towards Medea with sword energy.

"Rin! Switch!"

"Nice!" Tosaka Rin crouched down without hesitation to make way for Arthur to charge, and at the same time, she kicked out to block Bazett's obstruction!

Shirou Emiya stared at the scene in amazement and subconsciously clenched his fists.

He, he wants to fight too! He doesn't want to just watch!!

But Bazette shouted, "Well done!"

A strange rune suddenly appeared on her right hand, and the next second, a powerful force comparable to a treasure gathered in her hand.

Tosaka Rin's expression changed: "No way!?"

Bazette is the Lord of Protection! Can he actually release his Noble Phantasm?

That force instantly took the shape of a sword blade with a glowing halo around it. The strong light was almost blinding.

"——" Bazeto held the short sword that was almost made of light and stabbed at Tosaka Rin who was rushing towards him without hesitation.

The distance between the two was too close, and because of Tosaka Rin's momentum, she was completely unable to avoid it. From a distance, it looked like she had actively bumped into the attack that was like a treasure!

"Tosaka——!"

Because Shirou Emiya was staring at this place closely, he reacted immediately. He rushed towards Tosaka Rin and tried to block the girl.

Phew!

Bazette's backlight sword easily bypassed Shirou Emiya and stabbed at Rin Tosaka's head.

"This is an attack that distorts cause and effect, changing the outcome of the attack to one that arrives first. Once launched, it will definitely hit the opponent before it!"

Bazette looked at the boy standing in front of Tosaka Rin with admiration, and said with approval, "I'm the one who played the trump card first. She's dead."

But at this moment, a silent and dark gap appeared in front of Tosaka Rin.

"Flying Thunder God——"

The golden chain rushed out from the gap, and under the effect of the ritual that had been prepared in advance, Izawa Sugi's figure exchanged back and forth with Tosaka Rin countless times!

The rapid spatial change made Tosaka Rin dizzy, but such an exchange was effective. The continuous spatial transfer and extension successfully opened up the attack gap.

"Stop!" Ize Shan grabbed a knife with his backhand and attacked Bazert, "——Cut!"
