Author's note: Wow. 532 reviews and over 1K favs and followers. Thank all of you for the support. Anyways, kudos to hyperomegasonic26 for giving me this idea along with some ideas he came up with. I hope you like it.

Also, writing under the heat...is not fun...

Shirou felt awkward at the room he was in.

Which included himself, Arturia, Ishtar, Parvati, Irisviel, Kiritsugu, Waver, Diarmuid, Alexander, Caster Gilgamesh, Saber Lancelot, Saber Gilles, and Assassin Hassan (Asa-ko and Zayd).

And they were all in a party of some sort, in which Alexander, the King of Conquerors, was hosting.

And he dubbed it "The Fourth Fuyuki Holy Grail War Party."

Shirou sighed. "I shouldn't have accepted that invitation that appeared at the front of my doorstep earlier..."

(A few hours ago...)

Shirou was getting himself ready for the day. As he made his bed, he proceeded to leave his room. However, when he was about to leave the room, an envelope appeared in front of him.

"An envelope? Don't tell me it's from Merlin again..." Shirou thought as he picked it up. He then opened the envelope to see the contents inside. Inside the envelope was a folded piece of paper. As Shirou unfolded it, the paper was an envelope.

It said:

Greetings Emiya Shirou! The one who wrote this letter is none other than me, Alexander, the King of Conquerors! You have been invited to a party for everyone who was involved with the 4th Fuyuki Holy Grail War! The party will be hosted by me! There will be free food and drinks nearby, so come to the party and enjoy yourself! The party takes place at night at 7:00 pm in my room!"

From, Alexander, the King of Conquerors.

Shirou sighed as he finished reading the letter. "An invitation from the King of Conquerors...huh...well a party like this shouldn't be bad. And I could use this as an opportunity to find out what my old man did during the fourth Fuyuki Grail War as well..."

As the day went on, it was getting close to 7:00 pm. It was time for Shirou to head towards to Alexander's room. After asking other servants where Alexander's room was, he finally arrived at the front of his room.

However, as he got inside, what he saw shocked him.

First, Alexander's room was huge. Very huge. Probably the size of a castle room.

Second, there were multiple tables filled with plates of foods and drinks.

And third, was the people that were in the room, which included Arturia, Ishtar, Parvati, Waver, Lancelot, Diarmuid, Saber Giles, Alexander, Assassin Hassan (Asa-ko and Zayd), and Caster Gilgamesh.

"Hey Shirou! You're just in time!" Alexander said with a smile on his face.

"Ah! Emiya-kun?! What are you doing here?!"

"Senpai?!"

"Shirou? What are you doing here?" Irisviel asked.

"Shirou! You should try this! It tastes good!" Arturia said as she was grabbing some food onto her plate.

Kiritsugu didn't say anything.

"My queen. What are you doing here?" Lancelot asked.

"Ah! Hey Emiya Shirou! It's been a while! How are you?"

Waver and the assassins didn't say a word.

"Heh? So that's the Emiya Shirou that everyone's been talking about lately..."

"Well, looks like he has arrived and he's late."

Shirou sighed at the comment Caster Gilgamesh said and went into the room. This was one party he was never going to forget.

(Back to the present...)

"Wow. I can't believe that there was this many servants that came to a party related to the fourth Fuyuki Holy Grail War. Especially since Tohsaka, Sakura, and Waver-sensei are here as well, although I don't know why though..."

"Shirou? Is there something wrong?" Arturia asked.

"Hm? Oh, it's nothing. I'm just surprised that Tohsaka, Sakura, and Waver-sensei were here as well. Furthermore, I can't even believe Waver-sensei agreed to this type of thing," Shirou replied.

"I can't blame you. I'm surprised as well. Anyways Shirou, try this out. It's good," Arturia said as she showed him a piece of food to him. Shirou then went closer to where the food was a took a bite of it. "Well, how does it taste?"

Shirou smiled. "It tastes good."

Arturia smiled. "I'm glad you like it."

As Shirou and Arturia were enjoying themselves with each other, Diarmuid and Alexander looked at the scene in amusement.

"Well, this looks interesting to watch," Alexander said with a grin on his face.

"Yeah. The King of Knights acting like this...it intrigues me. What connection do the King of Knights and Emiya Shirou have?" Diarmuid asked.

"Who knows?"

Meanwhile, Waver was having a chat with Ishtar and Parvati, or rather Rin and Sakura.

"Can you still believe this Waver? That Emiya Shirou, the one student that you kept lecturing to him about his reckless actions at the Clock Tower, is actually a servant here."

"You're telling me. I'm surprised he managed to here, let alone you and your sister as well."

"Yeah. Imagine my surprise when I first saw you here."

"You're telling me. I've would have never thought seeing you in here again of all places, especially since you and your sister are goddesses now and the fact that you have alternate counterparts of yourselves. Speaking of which, are you and Luvia getting along?"

Ishtar let out a high-pitched grumble and started scratching her head furiously. At that point, Waver had his answer. "I guess not huh?"

Parvati let out a sheepish laugh. "Sorry Waver-san, nee-san seems to still have a rivalry grudge against her."

"I can see that," he said. "And I have a feeling it's all because of a certain red-haired reckless idiot over there..."

It was then that Alexander decided to have a few toast of words.

"Hey everyone! I would like to have a toast here to everyone who has precipitated and survived the 4th Fuyuki Holy Grail War! I congratulate all of you who have managed to be here! For now, let us have a toast!" Alexander said as he raised his glass. "Cheers!"

Everyone else raised their glasses and then started to drink. As they drank, Shirou then asked Alexander a question.

"Um Alexander, can I ask you a question?"

"Sure! What is it Emiya Shirou?"

"Well...I remember that Arturia told me that Archer Gilgamesh participated in the 4th Fuyuki Holy Grail War, so why is the Caster counterpart of him here instead?"

It was then Waver, Diarmuid, and Arturia then looked at him. Caster Gilgamesh let out a sigh.

"Hey! Be glad that I'm here instead my Archer counterpart! Originally, my Archer counterpart was supposed to receive the invitation, but I took it before he can receive it. Trust me, if he was here right now, he would have exploded upon seeing both Shirou and Ishtar. But mostly Shirou."

Everyone let out a sigh upon hearing this. "He's still mad about what happened earlier?" Shirou asked.

"Mad? More like he's furious about it. In fact, he's like a ticking time bomb, ready to explode at any time possible. I prefer to avoid seeing him for a while until he calms down."

Shirou let out a sigh. "Guess he'll always hate me forever...speaking of which, is his arm fine?"

"Yeah. It regenerated a while ago."

"Well that's great for him at least."

Caster Gilgamesh laughed at what Shirou said. "You shouldn't say that in front of him. It'll probably make him even more mad then before."

"You're probably right."

"So anyways! Anyone want to talk about something?" Alexander said.

"Yes. First of all, what is the relationship between the King of Knights and Emiya Shirou?" Diarmuid asked.

Caster Gilgamesh, Diarmuid, Alexander, Giles, and the assassins looked at Shirou and Arturia. Arturia took a few breaths as she grabbed Shirou's hand. She then said her answer.

"Emiya Shirou is my former master in the Fifth Fuyuki Holy Grail War. He is also my sheath and my queen," Arturia said proudly.

Caster Gilgamesh, Diarmuid, Alexander, Gilles, and the assassins were surprised at what Arturia just said. "Really?" they asked.

"Yes," Arturia said with a nod of approval from Shirou.

"Wow...I'm not sure to call it ironic or funny at the same time..." Diarmuid said.

"What do you mean by that?"

"Well...I'll say this. The fact that the King of Knights happened to serve the son of the mage who defiled my duel against her. And yet, the son has a strong sense of duty and honor, which baffles me."

"Is that so...speaking of which, was that the grudge you have against my old man?"

"Yes. During the Fourth Fuyuki Holy Grail War, I was engaged in a duel of honor against the King of Knights. However, during the duel, your father disgraced the duel by holding his fiancée hostage, then forcing my master to sign a geas and then forced him to kill myself in order to obtain victory."

Shirou was surprised to hear that his old man has done something like that. "I-I never knew that."

"Yeah. It was one of the main reasons why I hated your father. Sorry for you to hear that."

"Nah. I'm used to hear stories about my old man during my time at the clock tower."

"I see..." Diarmuid then took a sip of his drink. "And even though that servant over there looks like him but is not him, I can't help but scowl at him," he said as he looked at Kiritsugu.

"Hey. I'm not him," Kiritsugu replied.

"Is that how Waver-sensei became the second Lord El-Melloi?" Ishtar asked.

Waver sighed again as he took a smoke. "Not this again. For the last time, I did not earn the title "Lord El-Melloi II" like that easily."

"Speaking of which, I would have never expected Rider's master to be here of all places. And he has grown into a fine man."

Shirou, Ishtar, and Parvati were surprised upon hearing this. "You participated in the Fourth Fuyuki Holy Grail War Waver-sensei?" Shirou and Ishtar asked.

Waver tried to speak, but Alexander cut him off.

"Yeah! The first time I saw him when he summoned me, he was quite the small kid. Probably even younger than all of you here!"

"Really?!" Shirou and Ishtar asked. "Waver-sensei was a kid when he participated in the Fourth Fuyuki Holy Grail War?!"

"Yeah! He was the size of a little kid when he participated in the Fourth Fuyuki Holy Grail War you know! And he was scrawny too! Not like what you're seeing here right now!"

Shirou and Ishtar then thought the image of a young Waver. "A young Waver...what would he look like...?"

However, it was then that Waver got up and gave Shirou and Ishtar a slap on the head. "All of you don't dare think of anything funny, or else I'll hit all of you again..." he said in a menacingly voice.

"Y-Yes..." they all said.

After all, they did once seen Waver get mad and it wasn't a pretty sight for them, mentally scarring them for life.

"I would rather deal with Archer Gilgamesh than Waver-sensei when he's mad..." Shirou thought.

"A mad Waver-sensei is something I would rather not deal with again..." Ishtar thought.

"Although one thing that interests me, my former master..."

"Huh? What is it Rider?"

"Since when you were a fan of playing video games that involve strategy?"

At that moment, Waver spat out his drink. "W-What?! What are you talking about?!"

"Don't play dumb with me! There are times where I would see you playing a video game in your room! And it's a strategy game!" Alexander said, grabbing the attention of Shirou and Rin in the room.

"Is that true Waver-sensei?" Shirou asked.

"And don't you dare lie to us," Ishtar said.

Waver sighed as there was no way to hide his secret now. "Yes. I play strategy video games in my spare time. Is there a problem with that?"

"Well no. I'm just surprised hearing that you have a hobby like that," Shirou said.

"Yeah. But that does explain why every time you were done with a lecture, the first thing you do is to go to your room immediately," Ishtar said.

"Yeah...and it's the only thing that's keeping me from going crazy from all of the work I have to do..." he muttered.

Shirou then said something. "So everyone here was involved in the Fourth Fuyuki Holy Grail War in one way or another?"

"Yes! Everyone here was a part of the war in one way or another. Although there were some people who couldn't join, so their counterparts came in as representatives." Alexander said.

"Really?"

"Yes my queen. Originally, my berserker counterpart was originally to come here, but apparently...well...he wasn't able to notice the invitation..."

"The same goes for me Emiya Shirou. Originally, my Caster version was supposed to come here, but he's busy with what goes on with that crazy head of his in which, I'll admit, deeply ashamed for. So I came in his place."

"Is that so?"

"Yes. Trust me, you do not want to meet him." Saber Giles said as he took a sip of his drink.

"I see..by the way, who are you?"

"Oh. My name is Gilles de Rais."

"Okay, so what class are you Gilles?"

"Me? I'm a saber class."

"And you Lancelot?"

"The same my queen. I'm a saber class servant as well."

"Is that so? And what about you two? Ishtar? Sakura?"

"For me, my father was involved in the war and I end up getting myself involved in it minorly." Ishtar said.

"I-It was the same for me too, although my uncle was involved in it," Parvati said.

"I see. Just out of curiosity, who were the master and servant pairs at the time?"

"Well...it was King of Knights and that woman over there. Then it was me and Alexander, then there was my old teacher and Diarmuid, then there was Caster Giles and someone called Ryuunosuke, then there was Berserker Lancelot and Kariya Matou, and then there was the Archer Gilgamesh and Tokimi Tohsaka," Waver said.

Shirou and Ishtar was surprised upon hearing the last pair.

"What?! Gilgamesh was my father's servant?!"

"Yes."

"Tokimi Tohsaka...isn't that your father's name Ishtar?"

"Yes. He took part of this war as well."

"I see. And Kariya Matou...is that your uncle's name Sakura?"

"Yes."

"Yeah. Although I don't know who Assassin's master was. Who was he?"

It was then that Assassins Hassan (Asa-ko and Zayd) decided to speak up. "It was someone from the Church, who went by the name of Kotomine Kirei."

At that moment, Shirou, Arturia, and Ishtar mentally groaned upon hearing that name. "Really? Him again?"

"Not only that, but he along with his father, who was a moderator of the Church at the time, was in an alliance with Tokimi during the entirety of the war until Tokimi's death."

That sentence nearly got everyone worked up, save for Irisviel and Kiritsugu.

"Wait. So, are you telling me that nearly during the entirety of the Fourth Fuyuki Holy Grail War, those two were in cahoots with each other?!" Waver exclaimed.

"Yes."

There was silence in the room as they were processing over the fact that the Church actually broke one of its rules. Eventually, Ishtar broke the silence. "That...damn...fake priest! I knew he was fishy business, but this?! He was both a master and a member of the Church?! And he was in an alliance with my father?! That shouldn't even be even allowed! I'm glad that he's dead now!"

"I know. Just how did the Church not manage to realize this?" Shirou asked.

"Honestly, I have no clue," Waver said.

"Well. Guess we'll never know now that war was over," Alexander said. "Anyways, anyone else want to talk?"

"Yes! Just who was the winner of the Fourth Fuyuki Holy Grail War? I want to know!" Irisviel exclaimed excitedly.

While the servants of the Fourth Fuyuki Holy Grail War had faces of curiosity over who was the winner of that war, Shirou, Arturia, Ishtar, Parvati, and Waver put up a long face.

"What wrong? Was there no winner of the war?" Irisviel asked.

For a moment, there was silence in the room. Then Arturia decided to say the answer. "Well...in the end, me and Kiritsugu won the war."

"Great! And what wish did Kiritsugu made?"

"Well that's the thing...he didn't make a wish when the holy grail appeared. What happened was...he tried to destroy it."

At that moment, the servants who were in the Fourth Fuyuki Grail War were surprised upon hearing his. "Eh?! Buy why? Why would he destroy the Holy Grail?! It was in front of him, and he wasted it?! How come?!" Alexander yelled.

"Well...I suppose during the war, he realized that the grail was already corrupted from the very start of the war, and he tried to destroy it. However, it had an effect he did not expect."

"And what was the effect?"

Arturia then looked at Shirou before he took a deep breath. "The Great Fuyuki Fire."

Everyone besides Shirou, Arturia, Ishtar, Parvati, and Waver looked at him in confusion. "What's that?" Alexander asked.

Shirou sighed again. "It's the aftermath when my old man used his last command seal on Arturia to command her to destroy the grail. What happened was that there was a huge of explosion that took the lives of 500 people and 134 buildings. Furthermore, the explosion also created a giant fire that took a portion of Fuyuki and burned it to the ground.

Everyone looked at Shirou in shock over how the Fourth Fuyuki Holy Grail War came to an end. "W-Wow. I didn't know that happened..." Diarmuid said.

"Yeah. And all for a grail that doesn't even fulfill wishes..." Shirou muttered.

Everyone's eyes widen upon hearing that. "WHAT?!" they exclaimed.

"Yeah, you heard me. The holy grail was so tainted, it couldn't make a wish come true. And even if you did, all you would get was destruction."

"Whoa. I never knew that. I mean, wasn't the grail able to fulfill people's wishes?" Alexander asked.

"At first maybe. But because of what happened to the grail in the third war, it was unable to fulfill any wishes."

"So the grail-" Diarmuid said but was cut off from Shirou.

"Was completely useless to begin with. It was just a tool of destruction my old man tried to destroy."

Everyone besides Arturia, Ishtar, and Waver were surprised to hear that the holy grail that was fought for in the Fourth Fuyuki Grail War was nothing but just a pack of lies. However, Kiritsugu was the most surprised at what his alternate self tried to do.

"Wow. I can't believe my alternate counterpart did that..." Kiritsugu thought.

"You know, you seem to know a lot about the aftermath of the Fourth Fuyuki Holy Grail War Emiya Shirou. Care to explain why?" Saber Gilles asked.

Shirou was silent, causing Arturia, Ishtar, and Parvati to glare at Giles for a moment. It was then that he realized he touched a sensitive area he shouldn't have. "My apologies, it seems like I have touched a sensitive area about your past right? You don't have to say-"

"It's fine. I suppose I should explain how I knew all of this huh?"

Everyone then looked at Shirou, wanting to know the answer.

"It's because I was the only survivor out of the victims of that incident."

At that moment, everyone's eyes widen upon hearing this. "EHHHHHHHHH?! You survived that?!" they exclaimed.

"Yes."

"Wait a minute, you were the sole survivor of a disaster created by a tainted holy grail?!" Diarmuid asked.

"Yes."

"Did you protect yourself with some magic?" Alexander asked.

"No."

"So you survived on pure luck?!" Waver asked.

"Well...you could say that..."

"And were you a kid back then?" Caster Gilgamesh asked.

"Yes."

Everyone went quiet upon hearing that sentence. After all, they've all just found out that Emiya Shirou was the only survivor of an event like that without any magic or any protection.

"S-So what happened to you during then my queen?" Lancelot asked.

Shirou sighed again. "I just walked in the flames of the aftermath. Ignoring everything around me, just wandering there aimlessly. At one point, I was ready to die. It was then Kiritsugu saved me by implanting Avalon inside of me. And that's how I know so much about the event."

Everyone was silent from the event Shirou just said. Irisviel was crying while Kiritsugu, Diarmuid, Alexander, Lancelot, Gilles, Assassins Hassan (Asa-ko and Zayd), and Caster Gilgamesh looked Shirou in shock over what he just said while Arturia, Ishtar, and Parvati looked at Shirou in worry.

"Shirou...are you okay explaining the thing that nearly killed you?" Arturia asked.

"Yeah. I'm fine actually. Rather, my heart feels a bit lighter after saying my past."

"You sure senpai?" Parvati asked.

"Yeah."

"Wow...to think you went through all of that as a child...I now have even more respect for you Emiya Shirou," Diarmuid said.

"Hahahahaha! To survive a disaster like that...you must have the devil's luck Emiya Shirou!" Alexander said.

"Jeez. To think you were a victim of it...I'm sorry," Waver said.

"To think such an event happened to you my queen..." Lancelot said.

"Wow. I never thought you would go through something like that..." Giles said.

"Hmph. For a normal human like you to survive that...that's a bit impressive," Caster Gilgamesh said.

"Wow..." was all the assassins said.

"Yeah. Anyways, shall we continue the-" Shirou said, but was cut off from a sudden hug from Irisviel. "M-Mom?!"

"Wahhhhhhhhhh! Shirou! To think you went through all of that...mom can't help but cry over the tragedy you went through as a kid!" Irisviel said as she hugged Shirou even tighter.

"Guh...I get it mom...can you let me go now..." Shirou moaned as she was struggling to breath.

"Never!"

While Shirou was struggling with Irisviel's embrace of death, everyone looked at the scene with an awkward face.

"W-Wow. I seriously don't want to be in Emiya-kun's position right now..." Ishtar said.

"M-Me too..." Arturia said.

Soon, Iriviel got tired of crying and let go of Shirou out of her embrace, giving him some time to breath.

"Hey Shirou, can I ask you something?" Waver asked.

"Sure. What is it Waver-sensei?"

"Well, considering what happened at the end of the Fourth Fuyuki Grail War and since everyone here was a part of it...do you have a grudge against me who happened to be a master of the war?"

Everyone was quiet upon hearing Waver's question and were waiting for Shirou's answer.

After a few seconds of silence, Shirou said his answer.

"No. I don't have a grudge against you Waver-sensei. Because if anything, you don't seem to be the type of person who would kill other people over something or use others to do it. Rather, you seem to be the type of person who would do things with his own hands," Shirou said with a smile.

At that moment, everyone was amazed by the words Shirou gave to Waver. Even he was slightly impressed by Shirou's answer.

"I see." Waver then placed a hand on Shirou's shoulder. "Thank you for the answer Shirou."

"No problem Waver-sensei."

Alexander then let out a laugh. "Well said Emiya Shirou! Nice choice of words for my master!"

"Why thank you Alexander."

"Heh! No need to complements! Now let's just continue the party, shall we?"

"Yeah."

And the party continued...
