Opening the Second Dimension in the Style of FGO

"The Greater Grail is inside here. The path ahead is a bit complex, so everyone be careful not to get separated."

Cú Chulainn gave this warning.

"It looks like… a natural cave. Is this something that Fuyuki City originally had?" Mash couldn't help but ask.

"It should be. It's a semi-natural, semi-artificial structure. It's an underground workshop that mages have developed over many years."

As she said this, Olga Marie also glanced around.

"You seem tired?" Koizumi inadvertently noticed the listless Fujimaru Ritsuka off to the side.

"Eh!" Ritsuka was taken aback, seemingly surprised that Koizumi would even talk to it, but it quickly recovered and hurriedly shook its head. "No, it's just that I don't really understand these mage things. In the end, I'm just a second-rate mage. Because I'm good at physical skills, my specialty is only body strengthening magic. I don't even know much about healing or anything else, so I get a headache when I hear about things like magic workshops."

As it said this, Ritsuka couldn't help but rub its forehead, which made Koizumi chuckle.

"Actually, I don't really understand these things either. After all, I don't even know my own past, and I don't even know magic at all." As he said this, Koizumi couldn't help but scratch his head.

"So, I guess we're in the same boat."

"Haha… I guess so…" As if Koizumi's statement was very interesting, Ritsuka couldn't help but laugh.

"Hmm?" Remilia wasn't interested in these things either, but—

"Who's there!"

As she shouted this sharply, Remilia's right hand shot out a pink ball of light, which slammed into a rock behind them.

"Boom!"

Immediately, an explosion rang out from it, and Cú Chulainn realized who had arrived.

"No sooner said than done, and a believer shows up." As he said this, Cú Chulainn turned around to look ahead with a playful expression.

"So, you're still protecting the Holy Sword's master, huh?"

"…Hmph. I don't remember being anyone's believer. My job is just to give unwelcome visitors their marching orders."

As this voice rang out, the smoke slowly dissipated, revealing a man wearing combat gear, clutching a black bow in his hand, with dark skin, gray-white hair, and strange纹路纹路 on his face.

He was a man with a pair of unusually weathered eyes.

This was Archer! Archer, as an enemy!

Chapter 7: Lancer, Who Seems Like Caster

"…Hmph. I don't remember being anyone's believer. My job is just to give unwelcome visitors their marching orders," Archer said calmly.

"Isn't that just a gatekeeper? I don't know who you're trying to protect Saber from, but let's settle things here." Cú Chulainn curled his lip, then said in a deep voice, "Isn't an endless game boring too? Whether the ending is good or bad, you have to move the pieces first, right?"

"Judging by your tone, it seems you've grasped the situation? Since you understand the big picture, yet you're still indulging in your own desires… I can see that even as a mage, your nature hasn't changed at all. Then let me knock you awake with my sword," Archer said coldly, and then a pair of black and white swords instantly appeared in his hands.

"Boom!"

As soon as Archer finished speaking, another pink ball of light shot directly at Archer.

Archer was taken aback and dodged it directly, then turned his gaze to the attacker—Remilia.

"What a bunch of boring rhetoric. Desires, good and evil—it's all so boring. Are all you Heroic Spirits this uninteresting? And you, Caster, why are you saying so much to this guy? All you need to know is that this guy is the enemy!" As soon as she finished speaking, Remilia flashed in front of Archer, and Gungnir in her hand swung towards Archer.

"You're quite the efficiency expert, vampire…" Archer said with a mocking smile.

"Of course. It's so boring to be hung up on things like justice and desires! If I spent all my time thinking about justice and desires, I would have died hundreds of years ago!"

As she said this, a strong killing intent appeared in Remilia's scarlet eyes, and the Gungnir in her hand became even sharper. A huge wave of air swept around, and cracks appeared on the ground.

"That vampire Servant is really quick to attack," Cú Chulainn scratched his head and glanced at Mash.

"Little girl, don't just stand there dumbfounded, get in there!"

As he said this, Cú Chulainn quickly chanted a spell, waved his staff, and then a ball of blazing fire shot towards Archer!

Mash also rushed forward to block Archer's attacks for Remilia.

Remilia frowned slightly when Mash suddenly barged into her battle. She was about to scold her, but when she saw Mash's firm expression and sensed the aura from Mash that shouldn't belong to a normal human, Remilia hesitated for a moment and didn't say anything, tacitly agreeing.

Attacks were blocked, and then another attack came. Archer immediately made a decisive decision, leaping backward to create distance. After all, Remilia was stronger than him in close combat, and with Mash helping to block damage, it was impossible for him to hurt her. In that case, he might as well play the ranged combat game with her.

"Bang!"

A flash of brilliant fire and cold sword light, Archer slashed and extinguished the fireball controlled by Cú Chulainn. Then, magic power surged in his hands, and a plain black longbow and a black arrow appeared in his hands. After all, he was an archer, and even if he knew melee combat, it only meant that he was an archer who knew melee combat, and archers had some melee ability to some extent.

Faced with the disadvantage in close combat, Archer could only choose ranged combat, so—

The moment the bow and arrow appeared in Archer's hand, without the slightest pause, the arrow was already nocked on the bow and the bowstring was drawn!

Whoosh!

Archer released his hand, and the black arrow turned into a red light, heading towards Cú Chulainn like lightning.

Cú Chulainn also leaped back, but the moment the arrow hit the ground, a huge amount of magic power burst out from it.

"Bang!"

The arrow exploded instantly, engulfing Olga Marie, Ritsuka, and Koizumi.

"Senpai!" Mash was shocked. She really didn't expect Archer's arrow to explode!

Archer frowned slightly. In fact, that arrow was also meant to involve those Masters, but—

Based on his senses, they didn't seem to be dead yet, because he didn't get the feeling that he had killed them.

Remilia also paused her attack, her crimson eyes turned to look behind her, a thoughtful glint in them. She had a contract with Koizumi, and she would feel it if he died, so she knew he was alive.

She was just curious about what kind of Master she had. First of all, she couldn't feel any killing intent towards him, and even more strangely, she couldn't even generate any hostility in his presence. This was very strange.

Gradually, the dust settled, and Koizumi was standing in front of Ritsuka and Olga Marie, with a pink, wall-like barrier in front of him. Remilia frowned when she saw this.

If she wasn't mistaken, that was her magic. Did this mean that Koizumi could use her power?

Wait a minute! Are you kidding me? My magic is being fed back to him as power? What kind of bizarre contract is this?

"Senpai, Mr. Koizumi, Director, are you all right?" Mash asked with concern.

"We're fine... it seems we were saved by this guy..."

Olga Marie said, looking at Koizumi with a puzzled expression.

She was starting to doubt her judgment. Even though Koizumi was now displaying superhuman power, she was beginning to suspect that his amnesia might be real. If he was the one who caused this Singularity, there was no reason for Koizumi to save her and Ritsuka, especially Ritsuka. If Ritsuka died, Mash, as a Pseudo-Servant, would also lose her power.

But he didn't do that. Instead, he stood in front of them to defend them, so Olga Marie began to question her judgment.

"Be careful, Archer's arrows explode. Especially you, Mash, try to dodge Archer's attacks as much as possible when defending, unless it's absolutely necessary. Ritsuka and Miss Marie have me, so don't worry."

Koizumi stared cautiously at Archer in front of him. Although he didn't know why he had this power inside him, he knew it was Remilia's power, so Koizumi attributed it to the contract.

But now wasn't the time to worry about that. He had to deal with this Archer quickly.

"Eh... I understand!"

Mash was stunned for a moment. After all, normally, Ritsuka would be giving her orders, but now it was Koizumi, which made her feel a little uncomfortable.

"Hey, shouldn't Ritsuka be giving Mash instructions? How did it become you?"

Olga Marie couldn't help but complain about this.

"Director, don't worry about such things in this situation. Besides, I think what Koizumi said is right."

Ritsuka seemed to be a bit thick-skinned and didn't care about such things at all. On the contrary, it thought Koizumi's instructions were correct.

"Milady!" Koizumi ignored the conversation between the two behind him and looked at Remilia.

If he remembered correctly, Remilia also had ranged attacks. Since Archer wanted to attack from a distance, then they might as well have some fun with him.

"Understood!" Remilia subconsciously responded, shaking her hand.

But Remilia was then stunned. Wait, why am I listening to him? I'm the Milady!

Taking advantage of Remilia's moment of daze, Archer seized the opportunity, quickly drew his bow and nocked an arrow, aiming at Remilia. Then, several beams of red light burst out like lightning.

Sensing the attack, Remilia quickly regained her senses and dodged the attack.

At the same time, a huge magic circle appeared behind Remilia. In just a moment, countless light bullets burst out from the magic circle behind Remilia.

"What!"

Mash and Cú Chulainn were shocked, especially Cú Chulainn, who was speechless.

I'm the mage! Why is a Lancer more like a Caster than I am!

Ignoring Cú Chulainn's inner turmoil, Archer was also shocked.

A Lancer using Caster's methods? What is this? Did you just fill in your class randomly?

Instantly, countless explosions rang out from within. It wasn't that Archer didn't want to dodge, but there was nowhere to dodge. Even if he used attacks to defend, he would be caught up in it as well.

"Hey, are you sure your Servant isn't a Caster but a Lancer? This is clearly more Caster than a Caster!" Olga Marie also couldn't accept it, and Fujimaru Ritsuka also showed a speechless expression.

From the look in its eyes, Koizumi could read this message.

"Your Servant is too bizarre!"

Gradually, the smoke dissipated, and Archer, covered in blood, wore a wry smile. His body began to turn into particles of light. "This is really... meeting a unique Servant..."

"Hmph! That's because you haven't seen the world..." Remilia snorted and said.

Hearing this, Archer showed a wry smile. "Perhaps so..."

With that, Archer's body completely turned into particles of light and disappeared from the spot.

Seeing this, even Cú Chulainn couldn't help but show a wry smile and shake his head.

"This vampire lady is really efficient."

Well, who told him that he was almost useless in this battle?

Although it was good to be idle, being too idle gave him a feeling of not doing his job properly.

"Nonsense, if we waited for you to act, who knows when it would be."

Remilia glared at Cú Chulainn and said lightly.

Cú Chulainn sighed helplessly and didn't say much. As long as they could defeat the enemy.

However, unintentionally, Cú Chulainn glanced at Mash and realized that Mash seemed to be a little absent-minded.

"What's wrong? Little girl?"

"Although I'm very happy that Mr. Cú Chulainn trusts me so much, can I really block Artoria's Holy Sword? ...That... Artoria's Holy Sword that shook the world. I feel like it's beyond my ability. Just thinking about that Holy Sword, my fingers are still trembling."

As she said this, Mash looked at the shield in her hand, a lack of confidence evident on her face.

"Then we can only overcome it. But in my opinion, you should adapt to the Holy Sword very well."

Cú Chulainn patted Mash on the shoulder, offering words of comfort.

"That shield won't break. If we really lose, it'll be because you, the little girl supporting the shield, messed things up. If you let go of the shield, the Master behind you will instantly evaporate."

Saying this, Cú Chulainn pointed to Ritsuka standing to the side.

Hearing Cú Chulainn's words, Mash couldn't help but purse her lips, then a determined look flashed in her eyes.

"I will definitely protect Senpai!"

Chapter 8: Remilia's Shock

"I will definitely protect Senpai!"

Mash said with a determined expression. Cú Chulainn nodded, a look of appreciation flashing in his eyes.

"Listen carefully. Don't think about things like defeating the Holy Sword. You only need to consider how to protect your Master. You're good at that, right?"

"Well, that means taking care of Saber is up to me and Lancer. You go do what you want to do."

"...Okay. Your suggestion really gives me strength."

Mash gave a faint smile.

"What's wrong? Mash?" Ritsuka looked at Mash with a puzzled expression, she always felt like something about Mash had changed.

"It's nothing? I will definitely protect you, Senpai!" Mash said with a determined face.

"Okay, okay... I always believe in you, Mash." Ritsuka smiled knowingly.

From the moment she arrived at this Singularity until now, she had always believed that Mash would protect her.

Although Ritsuka could also fight, she was too weak compared to the Servants, so she could only watch from behind.

"Are you alright?" Remilia slowly flew in front of Koizumi, looking down at him.
