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

"A doctor? {←A Sub-Servant}" Mashu asked with a hint of doubt.

“……{←Follower}” indicates that he wants to be quiet now.

"No, I'm sorry, I wasn't clear enough!" Dr. Roman realized the flaw in his words. "It was the reaction of Servants other than you who came from the sea!"

"Thump----" The sound of metal scraping together appeared before everyone, and there was the enemy who had once been seriously injured by Nian Zhuo - the berserker Caligula.

“Something’s not right…” Nian Zhuo could see the berserker’s clenched fists, his twisted expression of gritting his teeth, his eyes completely bloodshot and devoid of any rationality—and the magic power level that exceeded what he had felt when they first met.

"I...I...!" The berserker, his face contorted in pain, ignored his dripping cloak and armor. The moment he saw Nero, his reason...no, he had no reason left at all.

"My actions... were... caused by... fate!"

"I offer...your life."

"I offer...your body."

“Uncle…!” Nero exclaimed in disbelief, having thought his deceased uncle was now standing before him.

"Huh, who is it? Nero's uncle?" Elizabeth, who was still bothering Nianzhuo, also sensed the unusual magical fluctuations.

"Oh dear, it seems his mind is quite severely bound. But that's how Servants are treated." Staring at the man before him, Stheno's already expressionless face darkened. "---However, this hobby is truly hard to agree with."

“The mind is bound…” Noticing the characteristics in Steno’s words, Nianzhuo quietly placed the driver on his waist again.

“Beautiful…so…beautiful…” Caligula suddenly changed the subject as he looked in the direction of Nero and his party.

"Suddenly appearing at the beach, suddenly hitting on me...!?" Elizabeth couldn't understand the man's thought process at all. "What...what do you want? Although I am indeed a charming idol...I already have a manager! But that beastly approach was too awful. What kind of royalty do you think you are?!"

"So...beautiful...beautiful...!" Caligula roared, seemingly praising some girl before him. "You are...beautiful! I want to take you, to covet you, to tear you apart. To take all your goddess-like purity and beauty...!"

"My whole body yearns to utterly ravage you! I... deeply love... my beloved sister's son---" His face was almost contorted into a grimace; the berserker had truly become someone devoid of reason.

"---Nero! Aaaaaaahhhhhh!" Caligula roared with fervor and rage, his muscles tensing as he crouched down like a beast, his magical power surging wildly.

“...Yes, you are a beast.” Raising the primordial fire, Nero also pointed the blade at Caligula. “You are no longer my uncle! My uncle is dead. I still cannot let go of the question of whether my uncle died with resentment.”

"But, but! If you are lost in death and appear before me, then let me perform the ritual of deliverance on your behalf. This is my duty as your niece, and also as a wise emperor…!"

"Come on, everyone, prepare for battle." Ritsuka quickly retreated to a safe distance and gave the battle orders.

Unexpected difficulties

Too powerful.

Even Nian Zhuo couldn't gain much advantage against the berserker who had completely gone mad, and was even suppressed by the berserker at one point.

Mash and Nero, needless to say, were already overwhelmed by Caligula's innate rationality, as they were a Demi-Servant and a human, respectively. Now, they could only defend themselves.

If it weren't for the fact that Carigula's target had always been Nero, Mash might already be somewhat "injured".

But the story is far from over, and the battle has entered a new phase.

“In that case…” He pulled a red watch face from his pocket and turned it, and Nian Zhuo’s figure was once again enveloped in a red ring. “This watch face is better for dealing with you.”

"Rider Time! Kamen Rider Zio!! Armor Time! Drive! Drive!"

Since we can't gain an advantage in strength, we'll win by speed.

Nian Zhuo took out the signal axe, his figure scattering red stardust as he rushed towards Caligula.

"Oh...! Oh...! Yu...! Yu's sister's daughter...!" Caligula roared, a crimson hue emanating from her body, a manifestation of her irrational, manic magical frenzy. Even the heat from her skin distorted the air.

“…! You are nothing but a dead man…!” Although he struggled to block the oncoming punch with the primordial fire, the berserker’s physical attributes and skills far surpassed Nero’s.

His red gown was torn, and his proud golden hair was somewhat disheveled. Yet the primordial fire in his hand never ceased to blaze, symbolizing the inexhaustible passion in Nero's heart.

"You've worked hard, Your Majesty." An attack came from the side, a strangely shaped axe tearing the earth apart. The sand and stones it carried briefly obscured the berserker's vision, allowing Nero to quickly retreat, planting his greatsword in the ground and panting heavily.

Nian Zhuo clapped his hands, placed the axe upside down on the ground, and beckoned to the berserker with his finger.

"Your opponent is me, Caligula..."

"Sigh~ Since the manager wants to fight..." Elizabeth swayed her long, slender dragon tail and stood beside Nianzhuo. "Then as an idol~ you can't just watch~"

"...How dare you block my way...! ――! ――!" With an unexpected roar, Nian Zhuo and the other man once again drew Caligula's hatred to themselves. Seeing Caligula rushing towards them, Nian Zhuo raised the signal axe without the slightest carelessness.

"--!" With a roar, Caligula threw a punch. His punching style was easy to see through when he lost his mind. His fist, covered in golden armor, and the swinging axe blade even squeezed out the air between them, creating a deafening sonic boom.

Blood gushed from Caligula's palms, yet it failed to give Nianzhuo any sense of victory.

As his axe blade was slowly suppressed, and he felt the immense force coming from his hand, Nian Zhuo's expression grew increasingly solemn.

At the same time, Elizabeth thrust her spear at Caligula from the side.

As expected, Caligula once again grabbed the tip of his spear with one hand. Caligula, who was blocking the attacks of the two Servants with both hands, was not at a disadvantage in the battle of strength.

……even.

"Click." With both hands gripping the axe blade and the spear handle in reverse, Caligula's face contorted as he slowly pulled the weapons towards him.

"Eh, eh?!" Elizabeth gripped the spear tightly with both hands, gritting her teeth as she tried to regain the initiative.

This was wishful thinking; even Nianzhuo, standing to the side, could feel the immense power of the man before him.

The once glorious B, living as a wise ruler for less than four years, could not alleviate Caligula's madness; on the contrary, it would exacerbate it.

He gains a bonus to resistance to mental interference attacks, and his strength stat will temporarily increase when he attacks with his bare hands. Caligula himself will also be injured when this effect is activated. His rampaging rage will overwhelm his spirit core.

Moreover, Nencho, who was familiar with the Servant's special abilities, knew that it was impossible to defeat him directly through strength.

Sadistic Tendency: A skill that provides a positive boost to their offensive capabilities during combat.

Emperor's Privilege: A. This skill, which should only be possessed by emperors of other classes, is not only possessed by the man before me, but is even at a rank of A. Skills that are not normally obtainable can be acquired in a short period of time through his own will. Eligible skills include riding, swordsmanship, art, leadership, and strategy. With a rank of A or higher, even physical burdens (such as divinity) can be acquired.

With the two weapons in his hands, Caligula's muscles tensed once more.

Then, with a roar, he threw the two of them away.

Amidst billowing smoke and dust, Elizabeth and Nianzhuo rolled several times on the ground before finally stopping.

Seeing Caligula roar and throw the two weapons at him like javelins, Nianzhuo decisively recalled the signal axe back into the system with a thought.

Then, without hesitation, it activated the high-speed mode, and the world suddenly seemed to freeze.

Everyone's expressions and movements became incredibly slow, but Nianzhuo remained completely unaffected by this state.

Grasping Elizabeth's gun as it flew towards him, he tossed it to the girl lying on the ground, then clenched his fists and charged forward again.

The tires on his calves and shoulders rolled, scattering red stardust, and Nian Zhuo's speed continued to increase.

"Drink!" Nian Zhuo's attack finally hit the berserker squarely, but it was far from over.

The second attack followed immediately. After activating his heavy acceleration, Caligula's speed couldn't keep up with Nencho's repositioning. Nencho finally regained the initiative briefly after being suppressed.

The sound of tearing muscles could be heard, and there were definitely some fractures in the ribs. The current situation was extremely unfavorable for Caligula.

In that case... there's only one way for Caligula to break out of this predicament now.

With his hands protecting his head, Caligula's magical power suddenly increased.

"Oh no! I can see he's about to unleash his Noble Phantasm! Stop him!" Dr. Roman's anxious voice came through Mashu's communication device.

Unfortunately, the duration of the accelerated mental state ended.

His legs trembled uncontrollably, and Nianzhuo's forehead, hidden beneath the mask, was covered in sweat.

After being thrown out, Elizabeth was too injured to continue fighting, and Mash and Nero, who were present to stop her, were not close enough.

"Ah... devour my heart, moonlight (Flucticulus Diana)..." he murmured, and the twilight in the sky suddenly vanished, and the bright, silvery moon hung in the sky once more.

This was not a good sign. Nianzhuo, panting heavily, took off the drive watch and then put the wizard's watch face in his hand.

"Oh... Oh oh oh oh oh oh oh oh...!" Moonlight shone on Caligula's body, and surging magic power erupted once again.

His wounds healed, his bones were set back, and even the fatigue and scars from multiple battles were instantly cured. However, none of this could compare to his panting, increasingly flushed and burning figure.

"Rider Time! Kamen Rider Zio!! Armor Time! Please! Wizard!"

A red magic ring enveloped Nian Zhuo's figure once more, and then the crimson-clad mage reappeared.

However, to Nianzhuo's surprise, before he could react, Caligula's fist grew larger and larger in his eyes.

"Damn it..." That was the only thought in his mind. Then, with a metallic twisting sound, Nian Zhuo was violently sent flying.

The shoulder armor on his body tore through the ground, shattering hard stones, and Nianzhuo's figure was buried in a pile of sand and gravel.

Kiva reappears

Buried among a pile of sand and gravel, Nian Zhuo felt an unbearable bitterness in his heart...

"How long has it been since I've been directly suppressed like this..." Lying in the pit, Nian Zhuo scratched his head. He could feel the surge of magic power on the other side. He struggled to stand up again.

"Alright... then let me see just how capable you are." Magic surged in his hands, crimson flames enveloping his palms, and Nian Zhuo stood up again, charging towards the roaring Caligula.

Their fists met, and both stared wide-eyed, trying to make out each other's faces {of course, please don't complain that Nian Zhuo couldn't see because he was wearing a mask}.

A smile tugged at the corners of his mouth, and Nian Zhuo was once again repelled.

However----

"Aren't your hands burning hot, Berserker?" Nian Zhuo shook his hands, which were covered in flames, and looked at Caligula, who was standing still.

To be precise, his hands were burned by the flames that had touched them during the brief moment his fists clashed.

"-!——!" The berserker's magic suddenly froze, then he unleashed an even more violent gust of wind that spread outwards. With each step he took, the surrounding earth crumbled. Caligula attacked Nian Zhuo with increasing frenzy.

"Ugh—!" Anticipating the direction of his attack, Nian Zhuo blocked Caligula's attack with his palm, but was still inevitably pushed back a considerable distance. "This guy's strength and agility..."

At least one of them reached the level of "ex", meaning immeasurable. At least, the punch in front of him had just exceeded Nian Zhuo's reaction speed. If his attack hadn't been so straightforward, Nian Zhuo would have been hit in the left chest long ago.

A surge of magical power erupted from his body, creating a barrier of flames that briefly blocked their line of sight.

"Finally..." clutching his chest, he retreated, but to Nian Zhuo's surprise, the berserker walked straight through the barrier of flames, determined not to give up until he killed Nian Zhuo.

"Is this some kind of unreasonable argument?!" Without thinking, Nian Zhuo hurriedly retreated, but Caligula's leaping kick struck Nian Zhuo's side.

"Hiss..." Nian Zhuo gasped, almost brought to tears by the excruciating pain.

Then, Caligula threw another left punch at him.

"No! Do I have no choice but to take this hit head-on...!" Nian Zhuo's body was forcibly displaced by the Berserker's attack, and he was unable to adjust his posture in time to block Caligula's attack.

Fortunately, he knows how to call for help.
