Ritsuka let out a sigh as he was in front of the doorway of the summoning room. "Well, today's the start of the new year, and it also means that today will be the first summoning of the new year! I've saved up my saint quartz and my summoning tickets. I wonder what I will get?"

The door to the summoning room opened automatically and Ritsuka went inside the room. Upon getting closer to the summoning alter, Ritsuka then dropped the saint quartz. The alter then lit up and Ritsuka was hoping that he would get a good servant.

However, instead of a servant, what appeared in front of him...was mapo tofu...and black keys.

Ritsuka was shocked for a moment. "Seriously?! Mapo tofu?! Black keys?! Again, after all this time?! Okay, calm down Ritsuka. Usually, the first summons are the bad ones, so something good may come out later..."

However, as time passed, Ritsuka's luck wasn't good at that moment as he kept getting craft essences and no new servants came by. Soon, Ritsuka ran out of saint quartz and was using the summoning tickets.

"Damn it! Guess it's up to the summoning tickets now!"

However, to his dismay, nearly all of the summoning tickets he was using came with bad results and what he summoned with them were more craft essences. Right now, Ritsuka was on his last summoning ticket, and he was almost in despair from the earlier results.

"Tch...I'm on my last summoning ticket...hope this one will summon me a good servant!"

Ritsuka then used his last summoning ticket, which in an instant, disappeared upon usage. The alter then lit up, then formed into multiple blue orbs. Then the blue orbs started to connect with each other and turned into a ring of blue sparks swirling around. Then the ring split into three and continued to swirl around. As the light faded, it revealed a gold card showing a robed old man wearing a hood with a long beard holding a staff while carrying a book at the same time. The card then disappeared and in its place revealed a teen. The teen looks slender, but hardy at the same time, has dark red eyes, and brown hair. His clothing consists of a black waistcoat, white shirt, black slacks, and a pair of half-boots. He was also carrying a sword on his waist.

"Um...servant... my name is Sieg. Sorry to disappoint you, but I'm just an ordinary homunculus. I may not be particularly powerful, but the Noble Phantasm that's been registered to me might be useful in battle. Use me as you see fit."

Ritsuka was silent for a moment before saying something. "Y-Yeah. Nice to meet you Sieg. Um...not to be rude or anything, but what class servant are you?"

"Hm...I'm not sure..." Sieg replied.

"I see...what skills do you have?"

Sieg was confused for a moment. "Skills? What do you mean by that?"

"Well, I mean something like magecraft or swordsmanship or marksmanship."

"Oh. I can swing a sword if that's what you are talking about."

"I see. Anything else special?"

"Well...I've obtained the heart of Siegfried and made it my own."

Ritsuka was shocked for a moment upon hearing Sieg's words. "Eh? Can you repeat that again?"

"Y-Yeah. I've obtained the heart of Siegfried and made it my own." Sieg repeated.

Ritsuka was silent for a moment while many thoughts came into his head. "He actually obtained the heart of Siegfried, the dragon slayer, and made it his own? But how though? Wait a minute, Siegfried mentioned earlier that there was a wish he managed to achieve on his own, so lending him his heart may be that wish. Still though, lending Sieg his heart...that's unheard of."

"Um...master, are you all right?" Sieg said, snapping Ritsuka out of his thoughts.

"Hm? Oh, yeah," Ritsuka replied. "Anyways, welcome to Chaldea Sieg."

"Chaldea? What is that?" Sieg asked.

"An organization that protects humanity."

"An organization that protects humanity. You mean like the mage's association?"

"Y-Yeah. Something like that."

"I see. Does it involve a magus family? For example, the Yggdmillennia clan."

"Well yeah. The founder of Chaldea is Marisbury Animusphere, the head of the Animusphere family."

"I see. Is there anything else that I should know about?"

"Well...this may come as a shock for you, but right now, we're in Antarctica," Ritsuka said.

Sieg was confused. "Antarctica? What is that place?"

"Well...I'll put it this way. It's a really, really, really, cold place."

"I see. Anyways, I hope we get along master."

Ritsuka smiled. "I hope so too."

It was then that the door to the summoning room suddenly opened on its own, revealing the person who triggered the automatic doors.

And that person was Shirou, who was carrying a large stack of papers in his hands.

"Hey there master."

"Hey there Shirou. What's with the giant stack of papers that are in your hands right now?"

"Oh this? All of these papers are reports from the Mage's association that you need to fill out later," Shirou said as he let them down.

Ritsuka mentally groaned at the stack of papers Shirou let down. "Really?! That entire stack of papers are something that I need to fill out later?! Just how much papers I need to fill out every day?! This is like high school all over again! Wait, it's even worse!"

Shirou and Sieg noticed the agonizing face that was on Ritsuka's face and asked in unison, "Are you right master?"

"Hm? Ah, it's nothing..." Ritsuka replied.

"I see. Anyways, master, who is this person over there?" Shirou asked as his attention was turned to Sieg.

"Oh him? That person over there is a new servant named Sieg, who is a homunculus who apparently inherited Siegfried's heart, literally."

Shirou was shocked at that moment. "Wow. I did not expect that. A homunculus that inherited Siegfried's heart? That's something unheard of."

"Um master, who is this person over there?" Sieg asked as he looked at Shirou.

"Hm? Oh, this is Emiya Shirou, a servant of Chaldea that was here before."

"I see." Sieg then raised his hand. "Nice to meet you Shirou."

"Y-Yeah. Nice to meet you too Sieg," Shirou replied as he shook his hand.

"Well, looks like these two may get along with each other..." Ritsuka thought as he looked at Shirou and Sieg greeting each other. Then an idea came into his head. "Hey Shirou, do you mind giving Sieg a tour of Chaldea for today?"

"Hm? Sure, I don't mind."

"Great! Sieg?"

"Well, I don't mind as well. Plus, if I'm going to be living here for now on, I might as well get a good look at the place."

Shirou let out a smile. "Well then, shall we move on?"

"Yeah."

And Shirou then left the summoning room with Sieg following him, leaving Ritsuka alone.

"Well then, now that's over...I guess I have to deal with all of this now..." he thought as he looked at the pile of papers and the large amount of craft essences he summoned.

"And over there is the training room, where servants go to that room to train and hone their skills. However, that room isn't limited to servants because master can go into that room as well," Shirou said as he pointed at the training room.

"I see. And that room over there?" Sieg asked as he pointed to a nearby room.

Shirou then turned to the direction to where Sieg was pointing. "Oh. That room over there is one of the recreational rooms in which servants and master can go into that room to relax."

"Wow. That sounds handy."

"It is. Anyways, shall we move on?"

"Yes."

And Shirou and Sieg continued their tour of Chaldea. Earlier, after Shirou and Sieg left the summoning room, they went on a tour throughout Chaldea to get Sieg to know what rooms Chaldea offers and Sieg was amazed with the variety of the rooms Chaldea offered. Not only that, but he was also amazed that such a high-tech building like Chaldea existed in Antarctica.

As Shirou and Sieg continued walking, it was then that they came across a servant that both of them knew.

Mordred Pendragon.

"Hm? Mother! And the homunculus!" she exclaimed as she approached them.

"Hm? Mordred?" Shirou and Sieg said in unison, causing both of them to look at each other.

"You know her?" Shirou asked.

"Yeah. She was a part of a holy grail war I was in. We were on opposite sides at first before we became allies," Sieg replied.

"Is that so?"

"Yeah."

Mordred finally got to where Shirou and Sieg was. "Hey there homunculus! It's been a while since I last saw you. So, you're finally here in Chaldea huh?"

"Yeah, and I have a name too you know. It's Sieg."

"Whatever. So, I take it that you met mother already."

Sieg was confused for a moment. "Mother?"

Mordred then pointed to Shirou. "Him."

Sieg looked at Shirou with a confused look. "You're Mordred's mother? But how?"

Shirou let out a sigh. "It's a long story..."

"Anyways, since when did you arrive Sieg?" Mordred asked.

"Today actually. Right now, Shirou is taking me on a tour today to see what Chaldea offers," Sieg replied.

"I see. Anyways, I got something to do with master now, so see you later!" Mordred said as she began to walk away before stopping shortly to whisper something into Sieg's ear. "Oh, and Sieg, if you somehow managed to hurt mother, I'll end you and send you back to the Throne of Heroes, got it?" she whispered menacingly.

Sieg nearly shivered at Mordred's words. "Y-Yeah."

Mordred let out a smile, knowing that her message was received. "Great! See you then mother! Sieg!"

And Mordred left, leaving Shirou and Sieg alone.

Sieg was surprised with what just happened. "Wow. I've never seen Mordred like this before..."

"Sieg, are you all right?" Shirou asked, snapping Sieg out of his thoughts.

"Hm? Oh, yeah. I'm just surprised with Mordred's behavior. She never acted like this when I first met her."

"I see. Anyways, shall we move on?"

"Yeah."

Shirou and Sieg then continued the tour of Chaldea. As they did, they were met with another familiar face.

Astolfo, one of the Twelve Paladins of Charlemagne.

"Sieg?! Is that you?!" Astolfo exclaimed excitedly, hoping that the reunion wasn't a dream.

Sieg let out a smile. "Yeah. It's me Rider."

In an instant, Astolfo jumped at him and gave him a hug, tackling him to the ground in the process. "Oh Sieg! It's been a while since I last saw you! How are you?" he exclaimed happily.

Sieg let out a chuckle. "I'm fine Rider. Although...can you get off me for a moment?"

"Oops. Ehe, guess I got a bit too excited for a moment..." Astolfo then got off from Sieg, which allowed him to get up from the ground. "Anyways, how are you?"

"I'm fine. How are you?" Sieg replied.

"Oh, me? I've been great! And let me tell you something, Chaldea is quite a fun place! There is so many servants here, some from other eras in history!"

Sieg was amazed with what Astolfo said. "Wow."

"Yeah! In fact, Jeanne is here as well!"

Sieg was speechless. "Really? Jeanne is here?"

"Yeah! Wait, you haven't met her yet?"

"N-No."

"Well then, what are we waiting for! Let's meet her then! I saw her a while ago! You can come too Shirou!" Astolfo then grabbed one of Sieg's arms and dragged him to where Jeanne was.

Shirou let out a sigh and soon followed them.

Jeanne D'Arc was in the cafeteria, sipping on a glass of tea. As she drank her tea, it was then that she heard a few voices coming. She turned around to see Astolfo at the entrance with a smile on his face.

"Hey Jeanne! I have a surprise for you!" Astolfo said excitedly.

"A surprise?" Jeanne asked.

"Yeah! And he's right here!" Astolfo said as he pulled Sieg over to Jeanne's view, surprising her immediately upon seeing Sieg at the entrance.

For a moment, there was silence between the two as they were trying to comprehend the reality that was now.

"Sieg...?"

"Jeanne..."

For a moment, nothing happened between the two. Then Jeanne got out from her seat and walked towards to where Sieg was.

"Sieg...is it really you?" Jeanne asked.

Sieg let out a smile. "Yes. It's me Jeanne."

In an instant, Jeanne lunged towards to Sieg and gave him a hug. "Welcome back Sieg!"

Sieg chuckled. "Yeah. I'm back Jeanne, and for good."

The pair then continued to hug while Shirou and Astolfo continued to look at the couple.

"Well then, looks like I made a happy ending for those two!" Astolfo cheered excitedly.

"Seems so, although this raises a lot of questions for me. First of all, how do they know each other?" Shirou asked.

"Well, it's a long story Shirou. You see, a long time ago, me, Sieg, Jeanne, Mordred, and a bunch of other servants were in a grail war. During that war, Jeanne fell in love with Sieg and vice versa as well. However, during the war, they were split apart."

"I see."

"Yeah. In fact, I forgot to mention this earlier, but Sieg became my master during the war."

"Really? How so?"

"Well...he became my master after Mordred cut my former master's head off."

Shirou felt a little disgusted after hearing Astolfo's words. "Jeez, that's...a bit gruesome."

"You can say that again."

As Shirou and Astolfo continued looking at the couple, it was then that a familiar voice came in.

"Oh my, this is quite the view."

Sieg and Jeanne nearly jumped at the voice and broke their hug while Shirou and Astolfo turned around to see who said that.

And the person who said that was Amakusa Shirou Tokisada.

Upon looking at Amakusa Shirou Tokisada, Sieg let out a frown with a small growl in the end. "Amakusa...Shirou...Tokisada!" he muttered as he prepared to draw his sword.

"Whoa there. Easy, I'm not here to fight. Relax," Amakusa Shirou said

Sieg was still not convinced. Shirou let out a sigh upon seeing his reaction. "Wow. It's like my reaction towards Gilgamesh and Kotomine..."

Jeanne put a hand on Sieg's shoulder. "Sieg, calm down. He's not here to hurt us. I can vouch for that."

Reluctantly, Sieg stopped drawing his sword. "Fine. But he tries to do something again, I'll kill him."

Amakusa Shirou let out a sigh. "Well then, looks like I'm not wanted here. Guess I'll take my leave then. See you," he said as he began to leave.

Sieg let out a sigh as soon as Amakusa Shirou was gone. "Jeez, even now, he still gets on my nerves."

"I can see that by your reaction. And I assume he was your enemy in the holy grail war you were in?" Shirou asked.

"Yeah," Sieg replied with a frustrated look on his face.

Shirou let out a sigh. "How about I make something for you to cheer you up? Would you like that?"

Sieg thought about Shirou's offer and said, "Yes. I would like that."

Shirou let out a smile. "All right, just give me a few moments."

Shirou then went into the kitchen while Sieg sat down on a nearby table. Meanwhile, Astolfo and Jeanne watched the interaction with awe on their faces.

"Wow. Shirou calmed Sieg down so easily..." Astolfo said.

"Yeah. Looks like those two may become friends," Jeanne said with a smile on her face.

Omake

"Sieg, while we're in Chaldea, there are some people that I want you to meet," Jeanne said.

"Really? Who?"

Jeanne let out a smile. "You'll see soon."

Sieg and Jeanne continued walking. Eventually, they reached a certain and walked in. As they did, Sieg was given a sight that he did not expect to see.

Which was Jeanne D'Arc Alter and Jeanne D'Arc Alter Santa Lily, who were doing their own business.

"Um...Jeanne, are they-"

"Yes. They're my little sisters," Jeanne said with a smile on her face.

At that moment, Sieg had one thought on his mind.

"Wow. She multiplied herself..."
