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

"Ah! Yes! Very... very good!" Ritsuka subconsciously raised her voice, even standing up straight, which made Mary both amused and exasperated.

“Yes, a very good rest. Your body has recovered to its best condition.” Mashu nodded, gazing at her face. For some reason, Mary showed a look of pity.

"I'm fine." Nian Zhuo shrugged, after all, he didn't feel anything from just a few hours of rest.

"I see." She nodded, then pointed behind her. "The food in the cafeteria is still hot. Eat quickly and then head to the control room. Romani, Da Vinci, and I will be waiting for you."

Mary then slowly walked out of the cafeteria.

"Ahhh! I'm starving!" No sooner had Mary left than Ritsuka rushed to the windowsill like someone who was starving, quickly grabbed the food, and then devoured it on the table.

"Really... no one's going to take it from you..." Nian Zhuo and Mashu both smiled helplessly, slowly finished their meals, and sat down next to Ritsuka.

"Alright, let's dig in!" Mashu and Nianzhuo clapped their hands, exchanged a glance, and then focused on the food in front of them.

The three of them maintained a satisfying silence, with only the occasional sound of chewing food breaking out.

However... if Chaldea never has any problems, is it still Chaldea? (humorous)

Suddenly, the light, which had been flashing a bright blue, turned red and sounded an alarm.

"Warning, warning—" A cold female voice rang out, causing the three people who were eating to stop what they were doing.

Ritsuka, who was drinking milk, almost choked to death.

"—Unknown force detected entering Chaldea! Unknown force detected entering Chaldea!" The next message made it impossible for the three to remain calm: "The location is in the training room. Those with combat capabilities, such as Nian Zhuo, are requested to proceed first!"

Then, only the buzzing of the alarm remained, echoing in the vast cafeteria.

“…Alright, looks like I’ll have to step in again.” Putting down the sandwich in his hand, Nian Zhuo stood up and patted his clothes. “You two can enjoy breakfast here for now. I’ll be right back.”

However, he was met with the sight of two girls standing up at the same time.

"It's alright, I'm already full." Mashu patted her stomach and shook her fist at Nianzhuo. "Besides, as a Demi-Servant, I am one of those who have combat abilities."

“Yes…yes…me too! I’m full.” Ritsuka stuffed the sandwich on the table into her mouth and chewed with difficulty, but still raised her hand to indicate that she wanted to go too.

“…You two.” Looking at the two girls, Nian Zhuo shook his head helplessly, then walked towards the cafeteria door first. “I don’t care what happens.”

"Understood!" The two girls immediately followed him.

The three arrived at the door of the training room, but wisps of black smoke, accompanied by a burnt smell, seeped out from under the door.

"..." Carefully grasping the doorknob, Nianzhuo and the other two exchanged a glance and suddenly pulled open the door.

However, Nianzhuo and the other two were stunned by the scene before them, their mouths agape.

A train came to a stop inside the breached walls of Chaldea.

Red, yellow, blue, purple... four humanoid monsters are sitting on the ruins.

Upon hearing the sound, they all looked up at the same time.

Happy Mid-Autumn Festival and National Day, everyone!

“…Huh?” Nian Zhuo stopped thinking when he saw the four familiar yet strange monsters in front of him.

However, the four humanoid monsters of different colors walked up to Nian Zhuo with an air of familiarity.

"Hahahaha!" The leading red monster, with small horns on its head and pure black eyes, sized up the dazed Nian Zhuo before placing its hand on his shoulder. "So that's it, you must be Nian Zhuo!"

"This..." Mash and Ritsuka stared blankly at the red monster with his arm around Nianzhuo's shoulder, momentarily unable to react. "Mr. Nianzhuo... is this your... friend?"

"Uh..." Looking at the red monster who seemed to know him so well, Nian Zhuo wanted to deny it, but that sense of familiarity was a catalyst that he couldn't shake off.

It refers to a spiritual energy entity that comes from a different timeline than the originally connected future.

Therefore, it can only exist in the form of sand, but by listening to human desires, it can obtain a physical body based on the images possessed by humans.

Those who hear the wish become contractors of the Otherworldly God. By actually fulfilling the wish, the contractor's memories can be traced back to the past world.

However, in most cases, the desire is forcibly fulfilled through distorted interpretations, and the contractor's true thoughts are rarely realized.

This is because the great purpose of the Otherworldly Gods is to change history and is connected to the future in which the Otherworldly Gods can exist.

Among these other demon gods, there is a faction of righteous other demon gods who are manifestations of future beings in the present world and who protect the passage of time.

Before him stood one of the righteous Otherworldly beings—Momotaros.

"Oh my!" Just as Mashu and Ritsuka were marveling at their strange friend, the blue monster among the four suddenly appeared before them. "My name is Urtaros. You two beautiful ladies, would you like to have a cup of coffee together?"

"Whoa!" Ritsuka, who was still a little drowsy, was so frightened by the monster that suddenly appeared in front of her that she quickly backed away. Mashu was in better shape than her, but she still opened her eyes wide and showed a surprised expression.

Then they saw the golden monster come over and grab the head of the monster who called himself Putaros, who was trying to flirt with them.

"Hmm, it's a rare occasion to see a junior like this, so you better be serious!" His voice boomed like thunder, and his burly physique revealed the immense power of this golden monster. "Putaros, I, Kintaros, will definitely keep your behavior in check!"

"...This." Faced with the suddenly appearing time train and the overly familiar monsters, Nian Zhuo was at a loss for words for the first time.

However, gunshots suddenly rang out from the time train that crashed through the walls of Chaldea.

"Ah!" The four monsters simultaneously clutched their butts, turning to look at the time train. "Dragon! You're doing this again!"

“A dragon…?” Nian Zhuo looked at the car door, and after a puff of smoke, the door finally opened.

A deep purple monster stood in front of the car door, holding a huge **** in its hand, which was still emitting a little blue smoke.

"Hahahaha!" A series of laughs came from the monster's mouth as it watched the four monsters clutching their butts. However, it was a young voice like that of a teenager. "You four are too embarrassing. This was my prank, you know. Hello everyone, I am Longtaros!" He raised his revolver and waved it at the group. However, no one could put on a friendly smile when they saw the monster.

Then, there was another soft sound of footsteps, and all four monsters stopped moving.

Another figure appeared at the entrance of the Time Train.

Leaning on a cane, it slowly emerged from the smoke, revealing its true form.

However, unexpectedly, it wasn't a monster this time.

Instead... a young man?

Wearing glasses, with messy yet upright hair, the young man adjusted his glasses and looked at the crowd in front of him with a gentle smile.

"...And this one? Is he human?" Mash and Ritsuka stared at the young man before them, then glanced at the four monsters scrambling around them. "Or...a monster with human bodies?"

“Ah, please don’t worry, ladies.” Setting his cane aside, the young man bowed slightly and then tapped Momotaros on the head, who was playing around, with his cane. “I am different from them; I am a genuine human being—while they are my companions.”

Finally, the young man turned his gaze to Nian Zhuo and waved to him with a friendly smile.

"And the purpose of our visit is to meet our juniors." The young man pointed at Nian Zhuo and looked him up and down.

"Mr. Nianzhuo... is he a junior?" Before they could even process the appearance of four monsters and a train, Mashu and Ritsuka turned their surprised gazes to Nianzhuo again. "So... you and... those monsters are from the same place as Mr. Nianzhuo?"

“Ah, no, that’s not it.” Playing with his cane, the young man shook his head. “To be precise, we haven’t met before, but we have some similarities.” Without elaborating further, the young man simply looked Nian Zhuo over for a moment before adjusting his glasses.

...Then he knocked on the red monster again.

"Ouch! That hurts!" The red monster, who called himself Momotaros, quickly covered his head and turned around. His tone relaxed noticeably when he saw the young man, and he even tapped the other man's shoulder. "Seriously, what are you doing, Ryotaro?"

“Ryotaro…” This time, it was Nianzhuo’s turn to examine the person in front of him. “So that’s how it is. He is the Kamen Rider Den-O’s hentai—Nogami Ryotaro.”

Unlike the naive and innocent type I remember, today's young people are obviously much more composed, and their eyes have become much more profound.

"Hey, hello there, Nianzhuo." Then, as if satisfied, he raised his hand and greeted Nianzhuo with a warm smile. "It really took me a while to find you, but we've come anyway."

"I am Ryotaro Nogami, the Time Patrolman of Love and Justice." Extending his hand, Ryotaro smiled as he gazed at Nencho's face. "Or perhaps it would be easier to understand if I were Kamen Rider Den-O?"

“…No, I do know about that, hello senior.” Nianzhuo reached out and shook hands with Ryotaro, their eyes meeting. “But what I care about isn’t that, but—” Nianzhuo looked at the Time Train behind Ryotaro.

"—How exactly did you get here?" Finally, Nianzhuo asked the question that had been bothering him, and his expression finally relaxed a little.

Yes, how exactly did they get here?

However, just as he was about to say something, the training ground door was opened again.

A panicked Mary, Leonardo da Vinci, and Dr. Roman appeared outside the door.

First, Nian Zhuo was stunned, then he saw the four monsters of different colors, as well as Ryutaros and Ryotaro standing in front of Nian Zhuo.

Finally, the focus shifted to the walls of Chaldea, which had been brutally smashed open by the train, and snowflakes from the blizzard outside were still pouring into the room.

"Ah...ah...repair costs, and compensation for all sorts of venues!" Da Vinci kept biting his thumb, put his staff aside, ran to the broken area, touched it with heartache, and picked up the broken stones on the ground to examine them.

Gradually, her gaze deepened, and unlike before, an oppressive aura emanated from her.

Exuding black energy, Leonardo da Vinci's hair seemed to float up naturally. Nian Zhuo could even see a huge ghost behind her, staring at him with scarlet eyes.

"Speaking of which, Nianzhuo." She smiled kindly at Nianzhuo, who was being scrutinized by the unknown monster, trying her best not to look too frightening. "I remember the last time the training room was under repair, it was because of you, wasn't it?"

"Uh—!" Because the memory was a bit distant, it took Nian Zhuo a long time to recall that the last repair was caused during his battle with Kirshtalia. He scratched his head and said, "Da Vinci, listen to me, this was really an accident, okay? This time, the cause has nothing to do with me!"

"Mo~" However, after scrutinizing Nianzhuo for a long time, for some reason, Longtaros suddenly ran over like an innocent child and grabbed Nianzhuo's arm. "Nianzhuo, you too, come play with me?"

"..." Staring at the other person's innocent expression, all Nian Zhuo got in return was a helpless sigh.

"Is that so?" Da Vinci pointed to Dragon Talos, who was enthusiastically inviting Nian Zhuo to play. "Do you have anything else to explain? Not only did you destroy Chaldea's buildings, but you also released four monsters with no clear intentions, whose true nature cannot be proven. To be honest, Nian Zhuo, if you were a magician, you would have been dismissed and sent for interrogation long ago."

Especially in this situation of utter devastation, the already somewhat repulsive staff members began to look at Momotaros and his group with growing hostility.

If Nianzhuo doesn't handle his relationship with them properly... or can't prove whether they are friend or foe... this matter might escalate into something much bigger.

Even so, Nianzhuo's account of their identities will not change.

"Uh..." Not knowing how to answer, Nian Zhuo looked around at the Imagin and Ryotaro who were all surrounding him except for Urataros. For the first time, he didn't know how to respond.

It's not like we're close... but it's obvious the other person came specifically to see me.

To say he was familiar with them... Nian Zhuo had no memory of ever meeting them, but that didn't bother him.

“…I guess so.” In the end, Nian Zhuo had no choice but to nod and admit it. “They are my friends, and I trust them just as much.”

"..." Upon hearing Nianzhuo's reply, Ryotaro, who had remained silent until now, revealed a knowing smile.

“Do you know the consequences of doing this?” Mary, who had been silent until now, spoke up, staring into Nian Zhuo’s eyes. Mary’s face was full of serious expression, and she looked completely different from the girl who would blush even when making eye contact with someone before. “Just the fact that you trespassed into Chaldea on this mountain without permission is enough reason for us to report the attack to the Mage Association.”

Then, she raised her hand, and two bright red Command Seals emitted a bewitching red light on the back of her hand.

"—And if the Mage's Association considers these monsters who destroyed Chaldea and whose true nature cannot be verified as hostile entities," Mary pointed at Nencho, her tone unchanged, "then you, who clearly knows them well, will also be punished by the Mage's Association, and may even be deported as a result."

Mary deliberately emphasized the word "repatriation," crossed her arms, and quietly looked at Nianzhuo, waiting for his answer.

At the same time, the staff's eyes were all focused on Nian Zhuo, as were those of Leonardo da Vinci and Roman.

Seeing Mary's serious expression, Nianzhuo couldn't help but smile.

She has always been like this, keeping her private and public affairs very separate—that's why she creates a strong image on the outside, but in private she's just a spoiled little girl.

"—Sigh." Finally, Nian Zhuo sighed helplessly, "It's precisely because of this contrast that I like her." He said softly, then slowly pushed away Long Talos's hand and walked in front of the five monsters and Ryotaro.
