Thanks for the invitation. I'm in Type-Moon, inheriting the legacy of Zi-O.

"Eh, so Mordred knows Jack the Ripper?" However, Ritsuka's focus wasn't on that. Looking at the angry blonde girl, she asked curiously, "Judging from your expression, it seems you and he have some kind of grudge?"

“Yes, that guy is a Servant.” Mordred nodded, though she was angry, she remained calm. “His class is Assassin. I’ve fought that guy a few times in the Mist…” Looking at the sword lying to the side, Mordred slammed her fist on the table.

“But every single time, that guy manages to escape.” Mordred pursed his lips in frustration, equally exasperated. “I never get a chance to deal with him; he always manages to escape using the fog! And I can’t remember anything about him—his appearance, build, or even his specific abilities. Ugh, this is so annoying…!”

“I understand!” Nian Zhuo nodded in strong agreement.

"When I hear the name Jack the Ripper, all I can think of is... Ah, I see, it's that Assassin!" Mordred rubbed her forehead, saying indignantly, "Ugh, damn it, my memory's so hazy! That bastard—"

"Perhaps you've encountered this before, Mash." Jekyll looked at Nencho, who was nodding repeatedly, then at Mash and Ritsuka, who looked bewildered. "Well? Do you have any memories of fighting Assassins?"

“Ah…” Mashu raised her head, rummaging through her memories, and finally bit her lip. “Right, now that you mention it… that person did seem to be an Assassin. A sneak attack…”

Suddenly, the sharp dagger seemed to reappear in front of Mash.

"Yes...we were ambushed!" Almost instantly, memories of Jack the Ripper flooded Mash's mind. "My memories just returned suddenly. Although I can't recall most of the details, since the attacker was a Servant, the reason is obvious—"

“It’s her skill.” Nian Zhuo suddenly spoke, while rubbing his head. “Although I’m reluctant to admit it, my memory is actually a bit confused. If it’s a Noble Phantasm… I should be in the same situation as you guys.”

“Yes, Mr. Nianzhuo, you’re right.” Mashu looked at Nianzhuo with some surprise, then nodded. “Then let’s tentatively conclude that it was caused by a skill.”

“That guy’s fast!” Mordred said, jumping up from the sofa and grabbing the sword lying to the side. “If we don’t hurry, he’ll get away. Let’s go!”

Mordred, who originally wanted to rest, has now become the most enthusiastic one.

Hearing the noise outside, Andersen opened the door to his study.

"What...are you going out?" Andersen poked out his blue-haired head as he watched Nianzhuo and the others packing their things to leave. "Really, you should have said so earlier. As for souvenirs...oh right, I'd like scones or something."

"Huh?! Aren't you coming?" Mordred looked at Andersen, who was peeking out of the study, with surprise. Then, after a moment's thought, she nodded knowingly. "That's right, even if you came, it wouldn't make any difference..." But just as she was about to leave, Mordred turned back.

"...Wait, will it be like last time, making it easier to defeat the opponent if I bring him along?" Recalling his experience with the magic book, Mordred looked at Nianzhuo and muttered to himself.

"Huh? It's no use, it's no use." For some reason, Andersen seemed to have heard Mordred's mutterings and waved his hand. "Last time was an exception among exceptions. Don't count on me. Besides, what can you expect from a writer? Do you think I'm an omniscient and omnipotent god? If you really think that, I advise you to give up that idea as soon as possible."

"Wow... what a sharp tongue..." Nian Zhuo turned his head away almost imperceptibly and said in a low voice.

Ritsuka and Mashu both nodded frantically in agreement.

"Listen carefully," Andersen continued, leaning halfway out of the room, wielding his quill pen. "So-called writers are just a bunch of fools who keep hitting roadblocks in reality and can only write! What use am I, someone like that!" He spoke with the strongest tone, stating the fact that he was utterly useless...

"...I must have been stupid to ask you that question." Mordred was silent for a moment, then reluctantly picked up his sword and walked towards the door. "Let's go, Nianzhuo, Mashu, and Ritsuka!"

"Hmph!" Suddenly, Momotaros snorted and turned his body to the side.

"Ah..." Nianzhuo suddenly clutched his forehead, looking utterly defeated. "I almost forgot about Momotaros..."

"Well, Nianzhuo, you guys go ahead." Unexpectedly, it was Ryotaro who came to his rescue, waving to Nianzhuo and nudging Momotaros, "Alright, alright, stop being stubborn, okay?" His tone was as gentle as a mother coaxing a child.

"Well, Ryotaro-san and Momotaros-san, you can just guard the base for us for now." Ritsuka swayed her orange side ponytail, looking at the sulking Momotaros, and whispered, "I heard there are still a lot of enemies around Jekyll-san's apartment~"

"..." Momotaros shifted his body.

“I—” Jekyll was about to say something when Ritsuka stopped him with a look, and he could only nod helplessly in the end. “Yes… there are still some… enemies around the apartment recently.”

“…Hmm.” Momotaros slowly turned her body to the side.

"Oh... well, the base is very important to us, you know. We wouldn't feel at ease entrusting it to a strong partner." Even Mashu helped with the act, though she wasn't good at lying and looked away.

"Haha!" Sure enough, upon hearing about his powerful allies, Momotaros stood up energetically and waved to Nian Zhuo and the others with a magnanimous air. "You can go with peace of mind! You can leave this mansion and this base to me! Hahahaha!"

“…Beautiful!” Ryotaro gave Ritsuka and the others a thumbs-up with satisfaction, though from an angle that Momotaros couldn’t see.

After calming Momotaros down, Nianzhuo and his group left the mansion again and headed to Scotland Yard, where they had sought help.

However, due to the dense fog and Ritsuka being an ordinary person, the group couldn't maintain a very fast pace. This led to Jekyll urging them several times through Chaldea's communication channels, as the situation at Scotland Yard was becoming increasingly dire.

Looking at the thick fog around her and Ritsuka, who was panting slightly, Mordred gritted her teeth.

"Full speed ahead." Mordred pointed at Ritsuka. "Mash, you carry Ritsuka and charge forward. We need to race against time. There's no time to match human speed now. Sprint straight to Scotland Yard at full speed."

“Okay…okay…” Mashu nodded quickly, now realizing it was a critical moment. She whispered to Ritsuka, “…Senpai, I’m sorry, I’ve been very rude.” Holding the shield in one hand, Mashu let Ritsuka lean on her back.

"No, it's me who should feel bad troubling you." Breathing slightly rapid, Ritsuka pressed herself tightly against Mashu, trying to lessen her burden. "But please don't drop me, okay?"

"..." Looking at this scene, to be honest, Nian Zhuo really wanted to summon his Knight motorcycle.

But a more pressing problem loomed before me... I don't know the way.

Having never even left a country in the previous world, it's impossible for me to instantly guess the entire layout of London in this world...

Another problem is that my motorcycle is too small... it can only carry two people at most.

If you bring Mashu or Ritsuka along, they'll just be staring at each other, neither of them knowing where to go...

Bringing Mordred along would mean leaving Ritsuka and Mash behind...

“Mr. Shinnosuke…” Nencho was now somewhat nostalgic for Shinnosuke’s cool Tredoron… “I hope that one day, I can drive that car too…”

"Ah... um!" Mash and Ritsuka, who were standing nearby, didn't hear Nencho's mutterings. Mash gripped Ritsuka's hand tightly. "...I'll be careful. I'll try my best not to drop you, Senpai. Please don't let go, Senpai!"

"Hey, hurry up—!" Mordred urged from the front, then suddenly stopped.

The sword blade on his shoulder swung down in an instant, clearing away the mist, and at the same time, the sound of something being chopped was heard.

"Tch, the enemy just appeared as soon as I finished speaking!" Mordred gritted his teeth impatiently as he looked at the dark figures that had surrounded his group without him even noticing.

Gripping her sword tightly with both hands, crimson lightning surged forth, and Mordred, having already warned Mash and Ritsuka, charged directly into the enemy ranks.

“…Damn it, at this time of year.” Mary’s voice came through the communication device of Nian Zhuo and the other two. Looking at the red dot on the screen, Mary put the report in her hand aside. “A large number of enemy attacks are coming from all directions! We’ll be surrounded, break through quickly!”

"At this time?!" Snapping out of his reverie, Nian Zhuo looked at the dark figures emerging from the mist from all directions, and gritted his teeth, feeling equally troubled. "Mash! Mordred has gone to take care of the front; there are fewer enemies in the back. I'll leave it to you!"

“Where is Mr. Nianzhuo!” Mashu nodded to show she understood, but before rushing over with her shield, she still looked in Nianzhuo’s direction.

"Me?" Nian Zhuo had his back to her, holding two watch faces in his hands at the same time. "...The following experiment is a little dangerous!"

The magenta and blue-red dials were placed on the driver at Nian Zhuo's waist.

"Decade, Build—!"

"Ding ding—Evolution unlocked!" The system's voice came from my mind, and at the same time, the blue and red dial on Nian Zhuo's waist changed slightly.

Glistening bubbles appeared around Nian Zhuo, and then rushed into the Build watch face on Nian Zhuo's waist.

"Perception, growth, evolution—proof complete!" The blue and red dial on his waist was gradually replaced with a transparent white border, and the image of the knight inside also changed.

"The Build watch face returns to its original form—the Build bubble form!"

"This is a huge help!" Feeling the belated power flowing through his body, Nian Zhuo flipped the driver at his waist.

A shimmering card appeared from above, while golden gears simultaneously circled around Nianzhuo.

Then it suddenly converged on Zi-O's basic armor, and a dark aura emanated from the gaps.

"Ahhhhhh!" At the same time, Nianzhuo's voice also came from between the gears.

The black smoke dissipated, revealing Nian Zhuo, who was entirely black but had magenta and red and blue eye armor.

“I never expected… to become like this…” Nian Zhuo moved his hands, surprised by the power he had gained. “The Danger Rabbit Tank after the Danger Trigger was activated… huh?”

It was precisely because of this that the bubble form, enhanced by the power of Decade, achieved an even greater leap, becoming the form of Dangerous Rabbit Tank.

"The law of victory has been confirmed!" A jet-black aura emerged in his hand, and the Time Gun Sword and the Ultimate Limit Sword simultaneously fell into Nian Zhuo's hands.

"Mash! Leave the enemies on both sides to me!" Taking on the enemies on both sides by himself, a dark aura gradually clung to Nencho's blade. "Perfect, let me test the power of this new strength!"

From the surrounding magical mist, all sorts of enemies, including artificial life forms, chaotic mechanical soldiers, and magical puppets, rushed out.

Surrounding Nianzhuo in the center, all sorts of enemies launched attacks on him simultaneously.

Nian Zhuo raised the strongest limit sword in his hand, and a dark aura rolled on the blade. He used his other hand to press the Build dial on the driver at his waist, and then flipped it.

"Over Flow—!" Unlike the usual ending sound effects, this time Nencho is using the power of Danger Rabbit Tank, so it is naturally the sound effect of Build.

“Hazard Finish——!” Dark mist condensed on the blade. Nian Zhuo held the blade horizontally, then spun it into a dark circle that swept towards the surrounding enemies.

In an instant, the artificial life forms, mechanical soldiers, and mechanical puppets that attacked simultaneously were all reduced to ashes by this one blow.

The area was cleared instantly, but Nianzhuo knew the battle was not over, so he quickly raised his sword.

A sudden change occurred, and Nian Zhuo could feel a pain spreading through his nerves as if a thorn had pierced them.

"Ah!" Unable to hold back his strength, Nianzhuo knelt on the ground, covering his forehead. "This—this is—!"

Everything before his eyes became blurry, and Nianzhuo seemed to be falling into a deep sleep.

"Even the side effects of the Dangerous Rabbit Tank—have they been inherited too—?!" Nian Zhuo desperately resisted the pain, but just as the scene before him gradually became clearer…

Clang—the sound of metal clashing rang out as a chaotic mechanical soldier broke through the mist, raising its saw blade and smashing it down on Nian Zhuo.

Nian Zhuo, kneeling on the ground, remained motionless until the mechanical soldier raised the saw blade again.

A black aura suddenly erupted from Nian Zhuo's red and blue eye armor, and he reached out and grabbed the mechanical soldier's head.

A dark aura clung to his palm, and then a dark current flowed through the mechanical soldier's entire body.

Nian Zhuo suddenly exerted force and crushed the mechanical soldier's head.

However, in the mind, mental turbidity is not so comfortable.

"Ugh—ugh!" The constant stimulation to his nerves, coupled with the anger from being hit by the mechanical soldier, made it even harder for him to control his emotions.

Then, just as he was about to lose control, two hands were placed on his shoulders at the same time.

"Is this all you've got? Your mind is clouded?"

The familiar male voice instantly calmed Nian Zhuo's nerves.

Emergency Rescue: A New Servant Appears Suddenly

"..." The scene before him gradually became clear, and control of his limbs returned to Nianzhuo's hands.

He looked down at his shoulders, and there was nothing there... only his black shoulder armor.

But in his mind, he saw two hands resting on his shoulders.

"Hey, this isn't the beginning of an experiment." A familiar voice, a familiar feeling.

When Nianzhuo turned around, he found two completely different people standing in front of him.

"Katsura Takumi... and Sento...?" I never dreamed I'd have the chance to see both of them together, especially with those helpless expressions on their faces... Huh?!

"Hey, Nianzhuo," Sento said, tapping Nianzhuo's head with a look of utter exasperation. "I thought the bubble was enough for you, but you actually managed to create a Dangerous Form... Don't you know how dangerous that is?"

“It’s not dangerous at all!” Katsuragi Takumi, standing to the side, strongly objected, “That’s my genius invention! It just has a few side effects!” He pointed his index finger at Nenjou’s back of the head.
