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

"Even so, I still believe in them." He said with a firm tone and an absolute smile, "They will never threaten the safety of Chaldea, and besides, they are my friends."

“...Is that so? I see.” Mary nodded, then turned around and walked straight to the door of the training room.

"From now on, keep a close watch on Nianzhuo and these unknown monsters while ensuring the work proceeds normally, and give them three days of observation. If no dangerous incidents occur after the three-day observation period, they will be allowed to stay here for a short time. That's all!" With her back to Nianzhuo, Dr. Roman and Da Vinci, Ritsuka, Mashu, and the staff, Mary said loudly before leaving.

“…She’s a really nice girl.” Ryotaro pushed up his glasses and smiled.

"Yes, she's a really great girl." Nianzhuo nodded vigorously.

They say they'll keep a close watch on things, but that's only on the premise of normal operations. Right now, Chaldea is barely functioning thanks to the surviving staff and Roman, Leonardo da Vinci, and Marie working overtime. Trying to maintain that while simultaneously keeping an eye on a monster is simply a pipe dream.

They even left three days, during which anything could happen in Chaldea, or it could have ended much earlier.

Mary only left instructions on what to do after three days, without explaining what to do should any situation arise within those three days.

This young girl continued to use her wisdom to think of Nianzhuo and the others, while also dispelling the concerns of some people.

"Ah—" Then, the girl suddenly stopped walking towards the door, as if she suddenly remembered something and turned around. "The repair fee and such will still be deducted from Nian Zhuo's so-called salary."

"Ah—" After a moment of surprise, Nianzhuo could only helplessly rub his forehead. "Okay, okay, I understand." Then, Nianzhuo watched the girl's figure disappear through the door, not knowing whether she had heard him or not.

Then, he turned around and looked at the staff who had calmed down considerably, as well as Leonardo da Vinci and Roman.

"Well, Romani, let's go too." Da Vinci smiled, waved to him, and walked towards the door with Roman. "Oh dear, that really scared me to death."

"Well, it must have been tough for you to play the bad cop." Dr. Roman touched his hair and smiled kindly. "But seeing them finally relax, you must be relieved too."

In the end, only Ritsuka and Mashu remained in the once huge training room.

Nianzhuo gently patted their heads and spoke in a persuasive tone.

"Alright, alright, you two. Go eat first." She whispered in their ears, "After you finish breakfast, everything will be over."

“Okay, alright.” Ritsuka nodded vigorously, knowing that staying here wouldn’t lead to anything better. “Come on, Mashu, let’s go. By the way, I believe in you too, Mr. Nencho.”

"Mm." Mashu nodded, slowly gripping the handle, and waved to Nianzhuo behind her. "Well then, good luck, Mr. Nianzhuo!"

Watching the group leave, Ryotaro smiled and nodded.

"What a kind bunch of strangers." Looking at the five otherworldly gods beside him, he was just no longer the same person he used to be.

“I don’t deny that.” Then, Nian Zhuo turned around and looked at the group of guests from other worlds in front of him. “Come on, let’s have an open and honest talk now.”

Why I came here

Nianzhuo silently looked at the five monsters sitting upright on the bed, and then at Ryotaro smiling across the table.

"So, senpai." He rubbed his aching forehead and looked at Ryotaro, who hadn't spoken since entering his room. "Why did you risk being exposed and becoming the enemy of this world to come to me?"

"Well, asking that is actually quite simple, isn't it?" Taking off his glasses, Ryotaro relaxed and pointed his index finger at Nencho in front of him. "Didn't we say from the beginning that our purpose was to see you, Nencho?"

"See me?" Looking at the other person pointing at him and smiling, Nianzhuo still couldn't believe it. "Why?"

“Because I’m really looking forward to it, to you becoming the new knight.” Ryotaro picked up his teacup, his gaze shifting slightly. “What kind of person will you be? What kind of personality will you have? I’m really looking forward to it.”

"Well, although I really trust you, Ryotaro-senpai." Scratching his cheek, Nencho looked at the man in front of him with a smile, "But this reason doesn't seem to be a valid explanation for why you came here..."

As for who they are, there's no need to elaborate.

“Is that so…” Ryotaro nodded in understanding. “I see.”

Stroking his chin, he thought for a moment before suddenly speaking, "Then let's just say we're here to help you. You see, you have some missions to do here too, right? Just explain us as your external helpers." Ryotaro casually pointed to the few restless Immortals wriggling on the bed.

"Ouch!" Suddenly, Momotaros jumped out of bed, clutching his butt, and looked at the other four Otherworldly Gods. "Hey! Which of you suddenly hit me?!"

Both Putaros and Quintaros looked at each other with an "what are you saying?" attitude, while only Rontaros turned his head away while whistling.

"Alright! Ryutaros, it's you, isn't it!" Just as Momotaros was about to pounce on Ryutaros, having seen through the culprit—

As he prepared to jump, his foot slipped...

As Momotaros's figure veered to the side, his red body was about to fall to the ground when he quickly grabbed a table and... the leg of the still-unresponsive Urtaros.

"Whoa!" With Momotaros pulling him like that, Urtaros's head collided with Kintaros's head again, making a heavy thud.

"Ugh!" Kintaros suddenly stood up, clutching his head. "Hey! Kintaros, what are you doing!"

"I didn't mean to!" Naturally, Putaros shrugged to indicate that it had nothing to do with him, and pointed to Momotaros, who was struggling to get up, "It was Momotaros who suddenly pulled me."

"Huh?" Momotaros, who had just managed to maintain his balance, almost fell to the ground. He stood up angrily, "You were the one who suddenly hit me, you know!"

"Eh~ I see~" Rontaros shrugged, his tone instantly irritating. "But I have absolutely no idea what happened~"

"You bastard—!" Sure enough, what he got in return was Momotaros's furious glare and a flying pounce that tried to pin Ryutaros to the bed.

"Bang bang—" The sound of palms clapping together rang out, and the two otherworldly demons, one red and one purple, started fighting on Nianzhuo's bed. Occasionally, Momotaros's angry snorts and Longtaros's laughter could be heard.

Seeing the two bickering, Putaros and Quintalos exchanged a glance and decided to watch the show from the sidelines, occasionally cheering them on, looking like they were enjoying the spectacle.

"—This." Nianzhuo looked at the chaotic scene, then at Ryotaro beside him who seemed used to it. "You're the one calling for help? I'll be thanking my lucky stars if he doesn't make things worse..."

"Well, there's nothing we can do about it." Ryotaro looked at Nencho, who, despite his complaining expression, had a smile on his lips. "How is it? Just like the people you remember, right?"

"..." Nian Zhuo's smile slowly disappeared, and he finally sighed, "Is that so? You still saw through me."

“Yes, after all, I’ve spent so much time with them.” Ryotaro’s smile remained unchanged, but he pointed to Nenjou’s eyes. “So, I do have some ability to observe people. How about it? Can you trust us now?”

Yes, Ryotaro saw the suspicion and distrust in Nencho's eyes from the very first time he met him.

Nianzhuo was indeed hostile towards them at first, because he couldn't tell whether they were friends or foes.

If Nen-cho obtained it in the form of a watch face, he would probably have become close friends with Momotaros and the others by now after entering the Mirror World.

But the format was different. This time, Ryotaro and his group visited in a very special way, which made Nencho somewhat suspicious.

Is the Ryotaro standing before me the overly kind senior I know? Or is he someone sent by that guy? Or perhaps he's from a parallel universe who has come here? Nianzhuo has no idea.

"Phew—" Nian Zhuo rubbed his hair and let out a long sigh. "But now, I can confirm it." He pointed to the opposite side, to his bed.

Momotaros and Ryutaros were still fighting, but although it was called a fight, it looked like they were just playing around, and nothing was destroyed at all—

While Momotaros was playing around, he gradually approached the edge of the bed and looked like he was about to fall off. Suddenly, Ryutaros pulled him back to the center with a strong force, and Urataros and Kintaros even gave him a gentle push from behind.

If their playful banter hadn't eased the tension, the conversation between Nencho and Ryotaro would probably have been quite awkward.

“So, you really are the people I remember.” It sounded a bit convoluted, but Nianzhuo still stood up and extended his hand to Ryotaro.

A smile returned to her face, this time a genuine, unadulterated smile of joy at seeing her senior.

"Welcome to Chaldea, Ryotaro-senpai."

"..." After a moment of surprise, Ryotaro picked up his glasses and put them on, and then grasped Nencho's hand as well.

"Ah, I'm honored to be here to help you, junior."

The pleasantries ended abruptly, and then Ryotaro watched as Nencho instantly ran onto the bed and joined the two otherworldly gods in their playful fight.

Raising an eyebrow, Ryotaro finally sighed, realizing that life here might really be very difficult.

But who knows what he's laughing about?

Come, let's head to the Fourth Singularity!

Now that they've become friends, Ryotaro and his group can be considered to have officially settled down in Chaldea.

Then, that night, Mary took them away... saying she wanted to put them in the same room for better supervision.

...Although it is called regulation.

But when Nianzhuo woke up the next day and saw that there was no one at the door and that his magnetic card could open the door, he was left with nothing but a helpless black line in his head.

"Ahem—" Looking at the several alien gods sleeping in a daze, Nian Zhuo coughed a few times and knocked on the already opened door. "Um, gentlemen, it's already morning—?"

"Hmm? Oh, I see." A voice suddenly came from behind the door next to Nianzhuo. Nianzhuo opened it and there was Urtaros, who was already stretching.

"Yo, Nianzhuo." Looking listless, Urtaros greeted Nianzhuo. "If it were that purple-haired girl who called me instead of you, I'd be so glad..."

"Alright, alright, Urtaros." Nianzhuo tapped the other's forehead, turning his body around as he nearly crashed into the door. With a hopeless look on his face, he said, "If you want to eat peaches, wait until they get up first—" pointing to the Otherworldly Gods on the ground.

"Huh? Momotaros?!" However, what Nianzhuo didn't expect was that Momotaros was the second to wake up, and immediately looked around. "Huh? Where's Ryotaro?"

“Ah, what Ryotaro-senpai said—” Nencho pointed to the windowsill on the side. Wearing glasses, he had been waiting for the other demons ever since he greeted Nencho when Nencho entered the room.

"Huh?" Momotaros looked in the direction Nencho was pointing, only to meet Ryotaro's amused gaze. Ryotaro even waved at him. "What's this? You got up just to do this kind of thing, Ryotaro—"

Then, Momotaros was suddenly pushed aside by Kintaros, who stood up next to him, while Kintaros raised his hands and roared.

"Oh—!" "What are you doing, you golden bear!" Naturally, Momotaros gave him a good scolding.

And then—all that was left was Nianzhuo looking at Longtaros, who was sleeping soundly on the bed.

"Hello, hello? Ryutaros?" He tried to shake the other's body, but Ryutaros just turned over and fell asleep again. "Hmm~ Ryotaro~ I don't want to get up..."

“Ah, this…” Nianzhuo looked at Ryotaro and saw that the other man also shrugged, indicating that he had no way to deal with Ryutaros’s childish temper. So Nianzhuo sighed and said, “Well then, let’s go have breakfast first. Just remember to bring Ryutaros a portion.”

"Well, let's go together, kid!" Paji put his arm around Nianzhuo's shoulder and Momotaros happily walked out the door first.

"Well, it really is unexpected..." Momotaros, with her hands behind her head, walked down the corridor of Chaldea with a hint of surprise in her voice. "The silver-haired woman who brought us here yesterday, although she said she would keep a close watch on us, seems to be the type who just talks the talk...?"

"Well, I like tsundere types too, you know?" However, as soon as Urataros finished speaking, he was hit on the head by Kintaros and Nencho at the same time. "Ouch! Ouch! Ouch! Ouch! Ouch!"

"If you can talk, then talk more." A grid of characters appeared above Nian Zhuo's head. He clenched his still-smoking fist. "Seriously, it's not good when someone is too similar to what I remember..."

"Well." Then he shook his head. "After all, that's just the kind of person Mary is. Don't let her appearance fool you, she's actually a very considerate girl."

"Is that so... I see..." Momotaros recalled Mary's gloomy face when they were talking, and shook her head. "Never mind, I just can't believe it..."

They chatted casually as they entered Chaldea's dining hall.

Ordinary daily life passed by like flowing water, and the treatment of Ryotaro and his companions in Chaldea also changed.

On the first day, when Nianzhuo was seen with Ryotaro and the others, all the staff in the cafeteria quickly finished their meals and fled the cafeteria at the speed of running away, leaving no one in the blink of an eye... leaving only a disheveled Nianzhuo... and the Otherworldly Gods.

Just watching them was enough to make the cafeteria staff break out of a cold sweat... not to mention that Putaros would occasionally break away from the group and suddenly approach the female staff. At that point, they would basically have to cover their ears and wait for the screams to subside before Nianzhuo and Kintaros pulled them back.

The rest was... Nian Zhuo also led them on a tour of the Chaldea area. Except for some places where Mary had written signs prohibiting unauthorized personnel from entering, Nian Zhuo led everyone to visit the rest of the area.

Along the way, they even encountered Mashu and Ritsuka, who were watching a videotape about Japan together.

Of course, they were also taken aback when they saw Nian Zhuo suddenly appear, and they turned pale with fright when they saw the monsters behind Nian Zhuo.

However, Nencho eventually managed to calm them down, and Ryotaro, who had seen the outside world, recounted the scenery of Japan to Mashu and Ritsuka... but in the way that was their world.

So when Mashu and Ritsuka heard Ryotaro talking about all sorts of weirdos, their expressions became very strange...
