"Jeez, I'm lost. Finding a way back home is hard…" a man said as he was walking with a katana on the left side of his waist. As the man continued to walk, it was then he sensed something dangerous, making him tense. "This presence…it's them?"
As the man slowly unsheathed his blade, the threat that was making him tense suddenly appeared on top of him, attempting to pounce on him. However, its attempt failed as the man easily dodged it. As the man fully unsheathed his blade, he got a good look at his attacker. The attacker itself looked like a mix between a wolf and a tyrannosaurus rex. However, its skin was nothing like them as there were various multicolored crystals on its skin, giving the appearance of having spikes. It had soulless, crystal-like green eyes that lacked irises.
"Tch…dimension beasts…" he muttered to himself.
The dimension beasts then howled and lunged towards the man, raising their razor-sharp claws to kill him. However, the man dodged it sideways and in the process, slashing one of them down, killing it. However, the other two then lunged at him by surprise, forcing him to jump over them.
As the man landed, the dimension beasts went for him again. However, he was prepared this time and turned around with his blade, slashing two of them at once. However, it was not enough as there still were others. "Tch. There's too many of them…guess I should go all out then…" It was then the man noticed there was a tiny tear in the distance. "Is that-oh no!"
As if it knew what the man was thinking, one of them headed towards the hole with great speed, passing him by with surprise. When it arrived towards the tear, it used one of its claws to slash the tear, creating a hole. With it, it escaped, and to his horror, others began to follow it.
"That's not good! It's planning to go to another world! Get back here!" the man thought as he began to chase after them, following them to where they were heading to. However, he was soon blocked by the others. "Tch…don't get in my way!" he said as he lunged towards the group.
(Meanwhile...)
Olga Marie let out a small sigh as she sipped on a cup of coffee. "Well, there seems to be no changes so far. No signs of changes in the earth or something like that. Just an ordinary day…" she thought to herself as she looked at a report from the Clock Tower. "Still, we can't be careless. Especially after what Gudako mentioned a long time ago, with the addition to the Clock Tower saying that those areas were dying off out of nowhere…"
It was at that moment that the intercom in her room began to ring. Immediately, she answered it. "Olga Marie here."
"Director! You need to come into the command room immediately! We have a problem here!" Da Vinci warned.
"What is it?!" Olga Marie asked.
"We have been receiving unnatural readings out of nowhere! It's similar to the vortex that me and Shirou were sent through a while back! But these readings are far more drastic than before! It's like something is crossing through dimensions!"
Immediately, Olga Marie prepped herself. "Get all personnel to head towards the shelter and get the servants ready for a fight!"
"Yes!" Da Vinci said as the commlink turned off.
Olga then left the room in a rush. "Another reading like that vortex that sucked both Shirou and Da Vinci in?! What the heck is going on here?! Don't tell me the alien god is coming earlier than we thought! Shit! I should have mentioned this to the servants!" Soon, she arrived at the command center, where both Romani and Da Vinci were. "Any updates on the situation?!"
"Yes! Believe it or not, there's a crack appearing in the sky!" Romani said, shocking Olga.
"A crack in the sky?! Where is it?!"
"The location…is here!"
Olga let out a groan. "Damn it, I should have known…get my subordinates to go to that location on the double to investigate it! I have a very bad feeling about this!"
"I can't believe there's a crack in the sky…Has this ever happened in your timeline?" Ritsuka asked.
"Nope. This is a first for me. Aside from that kaiju incident that happened a while ago…" Gudako asked.
"Guess so. However, based on my…well, our experiences with traveling to singularities, I have a feeling something is probably going to pop out of that crack." Ritsuka replied. "Mashu, put out your shield on standby."
"Y-Yes, senpai!" Mashu replied as she readied herself with her shield.
Ritsuka nodded before turning to the servants he brought…who were Shirou and Arturia. "Shirou, Arturia, I need you two on stand by just in case."
"Alright. But are you sure about this combination master? Don't you think we should bring more servants?" Shirou asked.
"I agree with Shirou. We are not sure what may come out of that crack in the sky." Arturia said.
"I know, but we are still not sure what will come out here. If anything, I can use a command seal to summon more servants here." Ritsuka replied.
"Still-"
At that moment, the group heard a shattering sound from the crack, forcing the conversation to an end. The group then readied their weapons, preparing themselves for what was going to come. As they turned to the crack, they saw that it was spreading further than before.
Then…the crack became a large hole…and out came from it were multiple beasts, shocking them. As the beasts landed on the ground, they let out a loud roar that sounded like a t-rex, but much deadlier and destroying the ground with them.
"What the heck are those things?! And did they come from the crack?!" Ritsuka yelled as he was protecting himself from the roaring.
"S-Seems so! Gudako-san, what do you think?!" Mashu asked.
"Honestly, this is nothing I have ever experienced!" Gudako replied. "Now we're dealing with interdimensional monsters?! What the hell?! This never happened in my timeline!" she thought before turning to Shirou. "Hey Shirou, you had experience with other dimensions after that god you fought! What do you think?!"
"I'm not sure! This is new for me too!" Shirou replied.
"Master, be on guard! They're about to attack!" Arturia said as she readied Excalibur.
Immediately, the beasts stopped their howling and started to attack the group. Shirou and Arturia stood in front of Ritsuka, Mashu, and Gudako as they slashed two of them. "Master!"
"Yes!" Ritsuka then raised his hand. "By my command seal…come!"
Instantly, the command seals on his hand began to light up, and then a bunch of servants arrived. "Everyone…let's go!"
"Well then, this is something new. Hope these things give me a good workout!" Cu yelled as he stabbed another dimensional beast. As he did, another came up in front of him, but Cu quickly pulled back his spear and twirled it around, hitting it with the end and knocking it down. Seeing his chance, he rushed towards the downed beast and immediately killed it. "Phew! This is giving me quite the sweat! I wonder how he's doing…"
Meanwhile, EMIYA was in the air shooting down his share of dimensional beasts with his bow. As he landed down on the ground, he quickly dismissed his bow and traced Kanshou and Bakuya. As he did, he went towards a nearby dimensional beast and took it out. "What the hell are these things?! And they came from a hole in the sky?! Even in my years as a counter guardian, I have never dealt with this before!"
"Hey! Dodge!"
Both Cu and EMIYA turned to see Ishtar, who began to fire a bunch of Gandrs at a bunch of beasts, forcing them to dodge. "Hey, hey, young lady! That was a close call!"
"Hmph! I did warn both of you at least! Anyways, we have to hurry dealing with these things! They are really ugly!"
EMIYA let out a small sigh. "She never changes…"
"Jeez, the skin on these things is really tough! And they're really fast too! Honestly, I'm not sure if I can handle any more of them!" Sieg said as he cut down a dimensional beast.
"Don't give up Sieg-kun! We can handle them together!" Jeanne D'Arc encouraged Sieg as she used her banner to defend herself and Sieg. "All we have to do is to hold on until more servants come in to help us!"
Sieg nodded as he took on another beast. "Hakuno, have you experienced something like this before?"
"Nope! The Moon Cell does not have any data of what these things are!" Hakuno replied as she shot a Gandr. "And they are annoying to deal with!"
"Yeah! Speaking of which, I wonder how he's holding up…"
(Meanwhile…)
"Sword Barrel: Full Open!"
Instantly, a bunch of swords were projected right behind Shirou. Mentally, he fired the swords at the dimensional beasts, taking them down. Despite that however, more continued towards him. One of them caught up to him and used its claws to try to kill him. However, Shirou defended himself with his Muramasa blade, blocking the claw strike. Shirou then pushed the beast back and projected another sword in his hand, surprising the beast and killing it. "Tch, there's no end to them!"
"Shirou!" Arturia yelled as she took down a beast with Excalibur. "Are you alright over there?!"
"Yeah! How's master and the others!? Should we hurry back to him?!"
"Yes! But first…we have to take care of these things!" Arturia said as she defended herself from an attack from a beast.
"You can say that again!" Shirou said as he attacked another beast. "However, something about these things seems…familiar, but what?"
(Back at Chaldea…)
"Jeez, this is crazy! No matter how many of those things everyone keeps beating, more keeps popping out!" Romani said.
"Exactly! It's like that kaiju incident from a while back! Only instead of giant bugs from space, we're dealing with a weird hybrid of a wolf and a t-rex with scales that look like crystals that came out of a hole in the sky!" Da Vinci replied as she monitored the situation.
Olga let out a groan. "Don't lose focus here! Da Vinci, have you figured out how to close that hole?!"
"Well…to be honest, I haven't at the moment here!" Da Vinci replied, making Olga groan again. "However, I did notice something though."
"What?"
"Well, for some unknown reason, most of those beasts are targeting Shirou, Arturia, and EMIYA! Like they're ganging up on them!"
Upon hearing those words, both Olga and Romani headed towards Da Vinci and looked at her screen. As they did, they noticed that most of the marked hostiles were aiming towards Shirou, Arturia, and EMIYA, which confused them greatly.
"Why them? Why are they so focused on them?" Romani asked.
"I have no clue. However, now I have an idea to get rid of those beasts easier!" Da Vinci said before she began to speak to Ritsuka. "Fujimaru-kun! I have a plan to get rid of those beasts quicker!"
"Eh?! You really want me to do that?!" Ritsuka asked in disbelief. "Uh huh…what?! They're being targeted the most?! I see…I'll see what I can do." he said as he cut off his comlink. "Mashu, Gudako, we have a plan, and it may be risky."
"Eh? Why?" Mashu asked.
"Oh no. That facial expression…I have a bad feeling about this…" Gudako thought.
Ritsuka then mentally communicated to Shirou, Arturia and EMIYA. "Shirou, Arturia, Archer. Da Vinci has a plan to deal with them quickly. Apparently you three are being targeted by them, so move to an open space. When that happens, I give an order to the other servants to use their weapons to kill them. You're okay with it?"
"So we just have to distract them. Sounds easy to do. Leave it to me, master."
"Alright, but you better not die you know! Or else I won't survive your family's anger! And everyone else that knows you!"
Shirou nodded before cutting the mental link. "Well, what do you think?" he asked Arturia.
Arturia let out a sigh. "Normally, I don't like this…but in this case, we have no choice. I wonder if Archer got the message…"
"You were saying?" EMIYA said.
Both Shirou and Arturia nearly jumped upon hearing EMIYA's voice before seeing him arrive out of nowhere. "Jeez! You nearly scared me for a moment!" Shirou said before calming down. "So, I take it that you know what to do?"
"Yes."
"Well then…let's get this started."
Soon, the three began to draw the beasts' attention away from the other servants…
"Well then, it looks like things are going well somewhat." Romani said as she was looking over her screen. "Although Shirou, Arturia, and EMIYA are distracting most of them, it seems that some are still dealing with the other servants. Hopefully, things can go smooth-"
It was then another alarm was heard. "What's going on?!" Olga asked.
"Let me check!" Da VInci replied as she went over to her control panel to take a look. "Oh no!"
"What?!"
"Something is coming out of that tear again!"
"Eh?! Something is coming out of that tear again!? Just how many more are going to come?!"
However, to their surprise, what came out was not a dimensional beast…but two things. First was a katana…and a person.
"A person?!" they said in unison.
(Meanwhile…)
"Tch! Even with Shirou, Arturia, and EMIYA distracting the others, we're still having a hard time dealing with ours!" Ritsuka thought as he shot a Gandr at a beast.
At that moment, a dimensional beast suddenly came up from behind, surprising both Ritsuka and Gudako.
"Senpai!" Mashu yelled in fear.
"Shit! I can't dodge that!" both Ritsuka and Gudako thought in unison.
However, before the dimensional beast attacked them, it suddenly fell to the side with quick force. As it did, Ritsuka, Gudako, and Mashu saw a sword stabbed in its stomach.
"A katana? Where did it come from?" Ritsuka thought.
And as if on cue, a man appeared right before them from the sky. The man has medium-short red hair with an ahoge and green eyes. He was wearing a white trench coat with gold accents on the shoulders, sleeves, and the inside of the trench coat is colored red. Underneath the trench coat was what appeared to be a black armored sleeveless suit. On his neck was a ruby pendant that was shaped like a diamond. As the man landed, he went over to the fallen dimensional beast and picked up the katana that stabbed the dimensional beast earlier.
However, the katana itself was not normal as the blade itself was in a crystal red color, the shape of the blade looked like a fusion of eastern and western designs, the guard was circle shaped and golden with a bit of red in the middle, a red and white handle, and a golden ornament that was shaped like a fan.
It was then the group noticed that since the man's arrival, the dimensional beasts did not move one step and focused their attention on the man, ignoring the others.
"Hey, are you alright?" the man asked.
For a moment, the group did not say anything until Gudako snapped out of it. "Y-Yeah. Thanks for helping us."
"No problem. Now then…need some help here?"
"Y-Yes!" Mashu replied.
"Very well. Let's finish this!" he said as he readied himself for a fight, pointing the katana at the dimensional beasts. At the same time, six copies of the same weapon appeared behind him.
"Projection?!"
Immediately, the man headed towards the dimensional beasts. As he did, he did a front flip over them, slashing one of them in the process. At the same time, the six copies left the man's side and went for nearby dimensional beasts, stabbing them. As he landed on the ground, a dimensional beast tried to attack him from behind, but the man quickly turned around and slashed it, killing it with ease. Another tried to kill him up front, but the man quickly dodged it while one of the katana copies went for his attacker and killed it immediately.
It was then the dimensional beasts got desperate and three of them tried to attack him at once in all directions. However, the man spun around with his blade in a circle, killing them with grace. It was then that one rushed at him with great speed, forcing him to move back. As he did, the katana copies returned to him shortly before he sent them back towards them with a hand gesture.
With quick reflexes, the man then headed towards the dimensional beasts again, taking them out one by one.
Meanwhile, Ritsuka, Gudako, and Mashu could only look in awe. "A-Amazing…" Mashu said.
"Yeah. He's cutting them down so easily…and he looks like he's not breaking a sweat…" Gudako replied in agreement.
Ritsuka nodded in agreement before contacting Da Vinci. "Da Vinci…are you seeing this?"
"Yes…who is that man? From what we know, he came out of the same hole those beasts came from along with that blade of his." Da Vinci replied.
"Eh?! Really?!"
"Yes. Which leaves the bigger question…what do we do about our mystery guest?" Romani asked.
"Hm…maybe we should help him?" Mashu asked.
"Eh?! Are you kidding me?! We have no idea who he is, let alone where he came from! He could be an enemy pretending to be an ally! Remember what happened before?!" Olga yelled.
"I understand director, and there is logic in your words…but for some reason…I feel like we could trust him. And…he seems familiar to me, but I don't know why."
For a moment, there was silence before a groan was heard from Olga. "Fine. But if anything bad happens, you better be well prepared for the consequences. Got it?!"
'Y-Yes!"
The commlink then cut off. "Well, what did the director say?" Gudako asked.
"Well…it's complicated." Ritsuka replied.
Meanwhile, the man continued his dimensional beast slaying as he kept taking them down one by one. As one attempted to attack him, he used his katana copies to surprise attack it, killing it with multiple stabs from above. As that happened, he went for another and slashed it down. However, another dimensional beast used that to its advantage and went for a sneak attack, forcing him to dodge.
"Tch. This is getting nowhere…guess I'll have to use that."
The man raised his hand and said one word.
"Manifest."
Instantly, another katana appeared in his hand. However, unlike the one that was in his other hand, the other one was slightly different as the guard was a red hexagon shape with emerald green in the middle, a gold and white hilt, an ornament that looked like a flame, and the blade itself was in an orange-red color.
However, what happened next shocked Ritsuka's group as the orange-red katana began to bright up lightly before flames appeared around it. With grace and elegance, the man started to dual wield the katanas with ease, not worrying about anything as he cut down every enemy he faced. At the same time, the katana copies returned to his side shortly before taking care of the other dimensional beasts.
If one would describe the scene in person, it was almost like he was dancing with the katanas and flames themselves.
"W-Wow…" Ritsuka said in amazement with everyone else nodding in agreement.
Soon, the man was done killing all of the dimensional beasts around him. "Phew. That's the last of them. Now then…where the heck am I?"
"Hey! Are you alright?" Ritsuka asked in the distance.
"Hm? Ah, yeah! I'm fine!" he said as he sheathed his katana and made his other weapon and katana copies disappear before heading towards Ritsuka and the others. "Is everyone alright?"
"Y-Yes! Thank you very much!" Mashu replied as she bowed down.
The man let out a small smile. "No problem."
"Thanks for the help there, but who are you by the way?" Gudako asked.
"I'm-"
It was then that two servants came towards Ritsuka's group. "Master! Are you alright?"
"Hm?! This voice!" the man thought.
In the distance were Shirou and Arturia, who had just arrived. "Is everyone all right?" Arturia asked.
"Yes, thanks to this man over here." Ritsuka said as he pointed to the man.
"I see." Shirou said before he turned to the man and raised his hand for a handshake. "Thanks for saving my master earlier. I appreciate it."
However, the man did not say anything.
"Is there something wrong?"
It was then the man dropped a bombshell that completely shocked everyone.
"Father? Mother? What are you two doing here? And why does mother look younger than before?"
At that moment, everyone stopped talking and stood still upon hearing the man's words. It was then that Ritsuka noticed something that he did not realize until now.
The man's facial features looked identical to Shirou's, but with a hint of Arturia's.
"Um…who are you?" Ritsuka asked.
The man was silent as he took a deep breath before saying his answer.
"Kenzaki. Emiya Kenzaki."
