Chapter 2: Tyrant's Battle

A few days later after his summoning, it was planned that they will go to a place called Japan. It was here that the Einzberns failed to anticipate another problem. Tatsumi cannot take a [Spirit Form], thus to blend in the Einzberns had to take a quick shopping run to get some clothes for him. Needless to say, some of the 'Modern Day Clothing' became a problem.

"Do I really have to wear such clothing?" Tatsumi asked. "Can't I just wear my regular ones? I can barely move..."

"One, you will stand out if you wear your regular ones," Illya enumerated. "Two, you cannot un-summon your sword, which is also a problem."

They had to use the old violin case as a storage case for Incursio's Key. And to complete the disguise, they had to make him wear a complete suit to make him look like Illya's bodyguard/musician.

Taking a private plane to Japan, Tatsumi was amazed that the people of this time were able to travel long distances around the world by air, sea or land. Flying though reminded him of his fight against the Young Emperor with the Shikoutazer, with the assistance of Wave of course. They landed in Fuyuki City, Illya then sent her two maids to their new home until this war has been concluded. A castle on the outskirts of the city easily defendable and also easy to escape from if the need arises, while Illya and Tatsumi planned investigated the city.

"Illya is everything alright?" Tatsumi asked as he stood next to Illya, hand ready to pull out Incursio's Key, when she stopped as a boy with red hair wearing a school uniform came to view.

Illya simply smiled and said with glee. "It's him."

She walked past him, he looked a little scared when she said, "Hey Onii Chan you better hurry up and summon yourself one soon or you'll die."

Illya then turned the corner quickly, Tatsumi kept with her easily. It was very late when they arrived at the castle, the two maids suggested that Illya has to take a nap before venturing out again.

"The three of us together, we'll make sure to save our village!"

Illya watched as three teens made their way down a path. One was a girl with silky long back hair and had a bow and a quiver full of arrows at her back. The two others were a boy with a bandana, who had an axe at his side, and a boy with brown hair which Illya recognized.

"This is his past?" Illya thought.

She watched as the three ventured, and was later confronted by bandits. She was impressed with their teamwork, the archer girl never missed, yet all her shots were aimed to incapacitate not kill. Tatsumi and that other boy never had trouble dealing with the bandits, she was surprised that Tatsumi used a short sword instead of the one he used. But when one bandit tried to get away, the other boy with Tatsumi took chase with the girl in tow. Tatsumi soon followed, but later could not find them.

"Dammit Ieyasu!" Tatsumi yelled.

"This maybe before he got his Noble Phantasm." Illya deduced.

She then watched as he ventured alone, and later confronted a beast called an 'Earth Dragon'. The mere sight of such beast scared Illya, but when she saw how quickly Tatsumi took care of such beast struck her in awe.

"He didn't even have his Noble Phantasm yet!" Illya thought.

Later, she saw that he was trying to enlist in their army but was later kicked out because of his pride as a swordsman.

"Dummy," Illya thought, "Of course that wouldn't work!"

She then saw a rather busty woman that wore clothes that left little to the imagination, Illya was jealous of course. She then saw that the woman persuaded Tatsumi to let her help him enlist at a cost.

"It's a scam I know it!" Illya thought. "Aaaand called it... Stupid Berserker, couldn't keep his hormones in check..."

She saw how Tatsumi was kicked out the bar and was left to sleep in the streets only to be helped by a Good Samaritan. A blond girl in her early teens took pity on Tatsumi and took him with her home. He was then later employed to be her new body guard, and was assigned to help her shop the next day. Later that evening, Illya saw Tatsumi bolt up from bed, and quickly ran outside.

"Night Raid!" Tatsumi said.

"Night Raid?" Illya thought.

She then saw the dead bodies of the guards, some sliced to cleanly, other had strange black markings on their bodies. As Tatsumi ran, a guard holding on for dear life told him to protect the girl. And he ran outside to confront the assassins. She saw how he held his ground from a red eyed girl wielding a katana that gave shivers down Illya's spine. She saw that Tatsumi was then stabbed, only to be saved by an idol placed over his chest.

"That would explain his Luck..." Illya thought.

What happened next was seared into her brain as she saw the busty woman from before, but she had animal like features that Illya found a bit cute, who then ripped out two metallic doors from a shed as if they were paper. Inside were mutilated bodies of people, and Illya could have sworn if she could have thrown up her dinner. She even saw the two people Tatsumi was with.

"Devils disguised as Good Samaritans," the busty woman said. "It makes me sick, you can kill them now Akame."

"Wait..." Tatsumi said.

"Don't tell me you will still protect her." the busty woman replied.

"...No..." Tatsumi said before he killed the girl. "I'll kill her myself."

Illya's eyes shot open when the dream ended. She then saw Tatsumi sitting across her examining his Noble Phantasm. But this Tatsumi was not the one in her dream, the dream Tatsumi had green eyes, this one had one red eye with a cross shaped pupil.

"What happened to him after?" Illya asked herself.

"Lady Illyasveil, Tohsaka Rin of the Tohsaka Family has summoned an Archer Class Hero, and then the boy Emyia Shirou has summoned a Saber Class Hero." one of the maids said as Illya got ready.

"Onii-chan and Rin-chan huh?" Illya repeated. "Time to have some fun."

"Why do you want to kill that boy so badly Miss Illya?" Tatsumi asked.

"Because he took my father away from me!" Illya answered in anger. "I'm like this because of him! I hate him!"

"Another pair of sibling that try to kill each other..." Tatsumi sighed.

"Master," Tatsumi added. "Why don't we just kidnap the boy? Wouldn't it be better if you talk to him?"

"I have nothing to say to him!" Illya snapped.

"Let me rephrase then," Tatsumi said, hoping that this will make the two sibling let go of their hate. "Let's capture the boy so you can... kill... him."

"I like your idea Berserker," Illya said. "Sure! Let's capture him."

After getting the whole overview of what Shirou had gotten himself to, both he and Rin left the church and headed their way back to the Emiya Residence.

"Well Emiya-kun, what do you plan to do? Today I will give you a cease fire, but tomorrow we will be enemies is that understood?" Rin said, her voice was dark and serious.

"Umm right? I ugh…" Shirou stammered.

"Shirou!" Saber said pointing at a purple clad girl.

"Hello Onii Chan, this is twice we've met like this." Illya said smiling.

Rin and Shirou both stood nervously as Illya walked forward and bowed before them.

"Hello Rin, I'm Illya. Illyasviel Von Einzbern. You heard of Einzbern right?" Illya said smiling.

"Einzbern..." Rin gritted. She then caught sight of the unarmored Tatsumi, wearing his white assassins jacket, purple hoodie, black shirt, black pants and combat boots. She scanned Tatsumi, and when she saw her stats she couldn't help but laugh.

"Really Einzbern?" Rin laughed. "Did you know that Assassin Class cannot fight head on?"

"Oh?" Illya replied with a smile. "But he is not Assassin Class, isn't that right? Berserker?"

"Rin!" Archer said as he prepared his bow. "That sword, I don't know why, but I have a bad feeling about it."

It's both a lie and the truth, that sword is a weapon that he cannot comprehend, it may as well be something that is only taking the form of a sword. Something living, something dangerous.

"Well then Berserker," Illya commanded. "Shall we do what we are here for?"

"Gladly." Tatsumi replied. "IN***SIO."

Smoke erupted around Tatsumi and when the smoke was blown away, it showed him donning his armor wielding a big spear. With a loud roar, he took of straight towards Shirou. Saber was quick enough to push Shirou out of the way and tried to stop Tatsumi in his tracks, but failed when the spear collided with her Invisible Sword with such force that she was sent flying towards the woods.

"No way!" Rin screamed. "His stats changed!"

"Rin! Focus!" Archer called.

"Archer!" Rin commanded. "Assist Saber! Now!"

"Are you sure about that? Saber barely defended herself, let alone protect you or her master..." Archer countered. "If he attacks you, I won't be able to stop it..."

"It doesn't matter... We have to deal with that thing one way or another... Saber can fight it but she needs your support... So don't question my orders and do as I say..."

"As you wish... Master." Archer muttered before he leaped into the night sky.

"That speed!" Rin thought as she watched Saber try to hold her ground against Berserker. "He fights as if he is a Lancer Class! Einzber, what the hell is your Servant!"

"What an odd Servant," Kirei thought as he watched the ongoing battle. "First he was likened to an Assassin Class, then his stats changed, but the way he fights, almost like a Lancer Class."

"So you're saying that this Servant can cover almost all classes aside from Caster and Archer?" another male asked.

"Master," a man wearing tight blue clothing said. "I wish to fight that Berserker."

"Very well," Kirei said. "Lancer, use your Noble Phantasm if necessary, kill Berserker."

Sparks flew as Saber lost ground against Berserker. He fought akin to a Lancer Class, with a spear and overwhelming speed, however he still possessed the raw power and rage of his class. She was sent flying again as she blocked a swing with her sword. Berserker then again ran towards Shirou, he is his target. With another Prana Burst, Saber closed the gap once more, and held Berserker off. She could feel that he is getting impatient with her. With a loud roar, he lunged at Saber and was able to grab hold of her Weapon, pulled her towards him with his spear poised at her.

"Saber!" Shirou yelled.

But he stopped as a red streak of light flew towards them. He pulled Saber and threw her towards Shirou before throwing both of them away from him.

Archer, though far away was able to see the battle he prepared his arrow, a strange spiral arrow, and knocked in onto his bow. Setting his sight upon Berserker and Saber, he was also able to see Shirou.

"My Core is Twisted in Madness," Archer said as he let the arrow fly. "Caladbolg!"

He smiled when he saw Berserker throw both Saber and Shirou with such force that both were out of the range of what will happen next.

"Looks like we have the same target eh Archer?" Lancer thought before he jumped upward.

"GAE BOLG!"

His spear glowed red as he threw it with such force it became a red streak of light flying towards Tatsumi's heart.

What happened next? An explosion that dyed the graveyard crimson red as the Cursed Spear Gae Bolg and Archer's Caladbog collided with the still standing Armored Tatsumi. He stood his ground as he took both attacks head on.

"Berserker!" Illya screamed as the wind from the explosion threw her hat away making her take a few steps backwards.

"Now then little girl," Rin smiled darkly as she approached Illya. "Let's have some fun shall we?"

Just before she could get near Illya, a familiar spear flew out of the smoke and impaled itself between Rin and Illya, makin Rin take a few steps back. She looked at the clearing smoke and her eyes widened form what she saw. There stood in the burning crater form both attacks, a lone armored figure stood proud. There were a few cracks on his reptilian armor, the cloth on its waist was tattered, but aside from that, no other visible damage could be seen. Berserker let out a triumphant roar before setting his eyes on Rin.

"He still had strength to throw that spear and protect her Master after such attack!?" Rin gasped.

"Rin!" Archer asked as he rushed towards his Master. "Are you alright!?"

"I'm fine Archer." Rin replied before she was forcefully pulled away narrowly dodging a swing from Tatsumi's spear.

"Well I gotta say Little Miss," Lancer said as he stood between Rin and Berserker. "Quite the Servant you got there, not many could stop my spear, oh and tell Archer he owes me for saving you."

With another roar, Berserker quickly closed the gap, grabbed his spear and swung at Lancer. Lancer thanks to his speed was able to dodge the attack, but was unprepared for what happened next. Berserker suddenly appeared before him with his own spear held high and swung downward. Lancer was able to awkwardly block the attack but was sent pummeling to the ground. Berserker held his spear poised directly towards Lancer when he heard his Master's yelp. Quickly he turned around to see Archer holding his Master hostage with a pair of black and white swords near her neck.

"Use your Command Seal," Archer said. "Do it!"

"No!" Illya screamed.

Archer then slowly pressed his swords on Illya's neck, drawing a bit of blood as he eyed Berserker. But as if a trick of his eye, Berserker vanished. And before he knew it, something punched him in the face making him let go of Berserker's Master. Berserker then appeared next to Illya with his own Master. Berserker held an unconscious Rin by the neck. Red eyes looking at him dangerously.

"Thank you Berserker." Illya said as she healed her wound. "But that's enough for tonight. We can already see you're the strongest servant in this war."

Illya then turned around and made her way back home. Berserker then threw Archer's Master towards him before following her Master.
