To say Rin was unhappy is an understatement.

Instead, she was frankly pissed.

'All of us went to Caster's place, and we accomplished NOTHING!'

Oh sure they learned a few things. Like the identity of Assassin, who's Caster Master is, some of the Servant's abilities. So yeah, that's a pretty good plus. However, it wasn't the desired result Rin wanted and despising the fact that Caster still lived. Not to mention that now Caster knew some of their abilities with Shinji mentioning that Assassin has a grudge against Saber.

Not to mention apparently a certain someone knew what those familiars Caster had were. As such, everybody is now in the Matou estate where Sakura was making food, with a minor magecraft used to ensure she doesn't hear them, while everybody sat in the living room. Where Rin glared at Ozpin, who had a calm facade on him despite her expression. Not that she'll let him get away with forgetting important information either way.

"So," Rin started as Archer stood by her. Saber doing the same with Shirou though looked glum, and Rider with Shinji. "You know what those things are?" Knew all along, and never told them so much as a peep. Even when those things prowled around the city.

Ozpin just spoke in a calm tone. "I do know them, yes. But I never expected them to be here, nor had any idea Caster even had them."

"Didn't Emiya here tell you about them when he first met Caster and saw those things?" So he should have known then by that point.

"I did feel the description was familiar." Ozpin admitted. "However, it wasn't as if I saw them personally until just a bit ago. And by the time I noticed them, it wasn't as if I could explain their presence since we were fighting."

A perfect answer, one with no real fault and the logic was sound. Everything said was okay and in truth, there wasn't any dishonesty in those words at all. Even so, Rin still couldn't find herself entirely believing him. Like he knew how to say the right words even in moments of crisis. Still…

"Moving on, tell us what you know about those things. Spare no details." Rin demanded, deciding to move on from suspicion for the time being. Ozpin nodding as he set his cane next to him while adjusting his glasses. Everybody now paying closer attention to hear what Ozpin had to say.

"The creatures we met," Ozpin began. "Are known as the Creatures of Grimm."

"Grimm?" Shirou said, already knowing that anything that used the variation of the word 'grim' couldn't be good already. "That's what they're called."

"Pretty much." Ozpin said. "They are, how to put it, destructive creatures that seek to destroy humanity. Attracted to negative emotions."

"That would explain why they went after that loser now." Shinji snickers, thinking about Kojiro while not noticing Saber's frown at him. "He was mad when he lost."

"Alright, so they're phantasmal beasts that prey on humans. Or I guess anything with sapience." Rin then said, thinking that the Grimm must only be attracted to those with sentient thoughts. "Actually," Rin looks at Ozpin. "Just what are they're parameters in targeting. Because I don't recall them going after animals."

"As you said before, sapience." Ozpin said. "Things like animals they don't bother unless it's for territorial disputes. As such humans are their main targets."

"Alright, but what are they?" Shinji then asked.

"Didn't you here him." Shirou told Shinji. "They're Grimm."

"No I get that," Shinji replies back. "What I don't get is where they come from. Or even what made them Because I never heard of Grimm before."

"Yeah." Rin grew suspicious before. "Same here."

Ozpin kept a cool mind, though knew he would have to improvise. So he spoke while keeping his voice at a calm level saying, "They're more common we're I come from...America. I don't suppose you know the situation there, do you?" While Rin still seemed to glare at him, she shakes her head. She mainly kept an ear in her home Japan, and she can admit to not knowing every phantasmal creature.

In fact, many countries had their own folklore of their creatures where the magus of those countries had better knowledge. Though she was confused however still, as why would a recent county that isn't even as old as others have these creatures. Ozpin saw the look in her eye and continued speaking.

"Truthfully, the Grimm aren't natural creatures. And I don't mean just because of they're appearance, but instead were made."

"As in an experiment?" Archer then asked. "A magus perhaps."

Ozpin nodded instantly. Seeing a way out of this. "Correct." He lied. "They were created by a dangerous man where they then more or less got loose and escaped. In fact, I work with a small group that deals with these creatures and so far we've kept them under control."

"That's a good thing I guess." Shinji said. "I mean, if those creatures were to get themselves seen in broad daylight, the Mage Association might make a move and deal with it and any witnesses."

"Wait, huh?" Shirou looked at Shinji. "When you say deal with witnesses, you mean...like hypnotizing to make them forget, yeah?"

"Maybe." Shinji shrugs. "But usually they'll kill." Shirou felt a bit of anger there. However, he then recalled the words of his late father. How he mentioned that the Mage Association were willing to kill villages to even towns if it meant creating the facade and keeping up the masquerade. Rin seemed slightly uncomfortable but didn't deny Shinji's words. He didn't like that one bit, and Shirou looked at Ozpin who also frowned. Weird.

"Does your group do that?" Shirou then asked Ozpin, who for a moment did look hesitant, then sighed.

"I...We...do try our best not to let people know about the Grimm." Not the Grimm. Her. "And if someone finds out, normally we can ensure the person doesn't speak. But I won't lie, sometimes...I have to deal with them personally." Those who discover the truth between him and her, and attempt to tell the world. Be it her or even him, that person won't last long. Only she was eternal.

Shirou for a second couldn't believe what he heard. Though before he could ask anything more, Rin interrupted. Whether that was for the best or not, he couldn't tell.

"Alright, so some mad magus in America made them and your group deals with them." Rin said as of matter-of-factly. Crossing her legs, she then gave a slight glare. "So then, why are they here? And more importantly, how dangerous are they?"

"How they are here, I honestly don't know." That was the truth. Though secretly, Ozpin did ponder if maybe...they came here in a way similar to him. Best to think about that later. "As for how dangerous they are, well...Quite frankly, the people of this town are dead if even a few get loose."

"Whoa there, they can't be that tough." Shinji scoffs as he then points at the Servants. "I mean, our Servants took care of them like so. And even Emiya took them out with ease. If anything, these things seem super weak and as such, handable."

"To Heroic Spirits, the most powerful familiars as Tohsaka put it and magus who can use magecraft with aura, then yes. They are weak." Ozpin then threw a dark and serious look at Shinji who then flinched at it. As Ozpin didn't like how Shinji gave such an unconcerned opinion of the Grimm. "But against normal people who have no aura, then they are abominations."

Remnant had been on the brink of collapse once before. Ozpin, Ozma, saw it.

When he returned the first time in his reincarnation, he saw how humanity had fallen from the first incarnation of it.

It was a nightmare.

While the Grimm were strong, the magic gifted to humanity by the God of Darkness allowed them to usually kill the Grimm successfully. A threat for certain, yes, but a manageable one. But the second group of humanity, that didn't even have aura then let aside Dust, saw the Grimm as a tide of death. A scourge that scared all to their core. One that continued to assault them even in modern times.

"My aura, your magecraft, and the Servants may seem to give all of you that the Grimm are weak. But know this, to the average person the Grimm are frightful beings who will tear you apart limb from limb." Ozpin said in a grave tone. "They can handle gunfire without so much as a care, tear buildings apart, sense humans no matter how hard they hide, and they never hold back. With the older Grimm capable of making plans to better kill their enemy."

While Shinji looked like he wanted to argue, Rin spoke up. "I suppose that's true." Rin admitted. "There's no denying that they only seemed weak, but that's just because we could handle them thanks to our powers. If these things were to really make a move then…"

Then as Ozpin said, Fuyuki would be having a nightmare.

"Then it seems we're in luck that most of these Grimm keep with Caster's home for some reason." Archer gave his input. Noting how while a few did stray away, the vast majority of the Grimm stayed with Caster. "However, I wonder if by taking her out, will that mean the Grimm will leave the temple grounds?"

"We can't let that happen." Shirou then says with Saber also agreeing with a slight nod. "If these Grimm really are that dangerous, then if we let them loose they'll slaughter people."

"And yet, by letting Caster live, she can use those creatures for her own plans while regathering her strength." Archer pointed out. "In the end, while tragic, we will have to deal with Caster even if it means those creatures are set loose."

"But then what about the people near the temple? Or living in it?" Shirou angrily puts out.

"I'm not sure about this either." Saber agrees as well. "I mean, we can't just let these things enter the city and start attacking." She then looked at Ozpin. "Can humans like the police even handle them?"

Ozpin thought back to James offer on his androids. Memory of them shooting at the Grimm failing despite how advanced they were and possessing high-level tech with them. "Frankly no." Those guns would be no different than pea-shooters to the Grimm. "That's not even mentioning they're abilities."

"Abilities." Rider, who had been silent this entire time, tilted her head. Interest caught. "As in, powers?"

"You didn't mention this." Rin seemed to accuse with Ozpin taking it in stride.

"I was going to explain it eventually, and now seems to be the time." Ozpin then spoke of the Grimm's innate powers. "While most of the Grimm you've seen rely on physical force, I should warn you some Grimm possess unique and rather unnatural powers." Powers that used to be easily dealt with in his time. "Ranging from basic fire breath, acid spitting, possession of inanimate objects, to draining one's will and even instant death. Though the last one really belongs to a rarely seen type."

"That's...scary." Shinji whimpered before realizing he said it out loud. Then coughed and tried to make up for it. "But nothing we can't handle."

"Sure." Rin rolled her eyes. "Regardless, I hope you can later give papers of Grimm we have to watch out for. This will-draining one sounds especially dangerous."

"I will. And rest assured, I will do my best to ensure the Grimm don't have their way with the people of this town."

"Same." Shirou said while still giving a glare at Archer. "And we can deal with Caster and the Grimm at the same time."

"I'm with you Master." Saber agreed, seemingly gaining back some of her spunk. "If you need me to kill those nast Grimm, then I'm your blade. Heck, maybe I can teach you like I taught my adopted son, Iori."

Ozpin smiled a bit. It seems that despite knowing of the Grimm, Shirou and the others weren't going to quit just yet. As such, "Very well then." Ozpin stood up. "Emiya, let us continue our training. While I mainly use my cane, I know some sword-technique and I bet Saber can help in that too."

"Wait, really?" Shirou looked at Saber who grinned, also willing to help her Master out.

"If we're going to continue and fight, then we must train. That includes you as well Matou." Ozpin said to Shinji who looked surprised.

"Me?" He pointed at himself.

"You have a good amount of aura. And I noticed you have a stance taken for archery I believe." Ozpin tells him. "Surely you wish to prove yourself on the field, do you not?"

Shinji gulped a bit. He saw some of Emiya's training, and especially how he got beat up a bit. Laughing in secret when he saw that. Thinking it was pretty funny. And now, he was about to experience the same thing. 'But...doesn't that mean he sees worth in me?'

Then that question lingered in Shinji's mind.

All his life his grandfather never expected anything of him. Seeing him as a fool, the bastard. But here though, this guy wanted to train him, because he saw something in Shinji. An uncertain feeling rose in Shinji at that, but it wasn't a bad feeling.

While a part of him knew this would suck, Shinji could only growl as he then just got up. Then put up his prideful look and said, "Fine." Putting a hand on his hair, he smirked. "I suppose Emiya could use a training partner."

"Then we start now."

"...huh?" Shinji gaped.

Emiya then felt a hand on his shoulder and saw Saber grinning at him. "Come on Master. Time to get started."

"W-What about food?" Shirou just asked as Saber began pulling him away. With Ozpin doing the same to Shinji.

"Oh you can eat later." Saber tells him with a gleam in her eyes. "I mean, a good sweaty training will get you appreciating the food more."

Shirou got a bad feeling and so did Shinji. Yet both were unable to do anything as they were dragged away for a long, rough, and rather painful beat down. Rin watching all four leave with Rider going after them as she then sighed. Boys. Though once they left, Rin gazed at Archer. "So, you think he told us everything."

"On the Grimm, mainly. But like you, there's no doubt he's still hiding something." Archer replied with Rin agreeing on that part as she then gazed back to the spot Ozpin last sat in. Eyes full of suspicion at his words, but more particularly on what he said a while ago.

"So a magus created them, huh." It wasn't abnormal to think a bunch of magus would make a new life form. Heck, it happens often actually with the main problem being they didn't last long and died off. Though in this case, it seems the magus who made these Grimm bit off more than they could chew. However, that never explained why they were here.

"America is a long way from Japan." Archer spoke up. "Not to mention, we never knew why he came here when the Holy Grail War started."

"You think he brought them here then?" Rin simply asked.

"I don't think so, but he knows more than he lets on." Archer gave his response to his Master. "Not to mention this aura his, it's a magecraft I never heard of. Plus how is it that the Mage Association never heard of these Grimm."

"America isn't really on the Association's list of interest." Rin told him, as the country wasn't much in terms of worth within the world of magecraft. Having few magus there at all compared to other places. "Still, it doesn't change the fact that the Grimm and this guy are involved together in some way. Not to mention, he said group yet where are the others?"

"Should we take him out?"

"No. Until we learn more, keep him alive. He's still useful after all." But if he tried anything that could threaten this city, then all bets were off. Because whoever Ozpin is, his secrets may end up ruining them all. Something Rin will not allow.

Sakura finally finished the food. Glad it was done.

This meant senpai can eat it and relax after the fight he no doubt had just about an hour ago. Sakura saw him. Him and the others looking tired. No doubt Holy Grail War business.

The spoon in her hand bent.

"..oops." Quickly Sakura bent it back, yet even then her feelings didn't go away. Especially her thoughts on senpai. Of how he was now going out and coming back tired, hurt, weary.

It made her feel pain in her chest.

'It's alright though.' Sakura told herself. 'Because Rin is helping him along with ni-san.' Shirou should be alright then. He had to be. He even had a strong Servant. Even with these thoughts though, Sakura still felt pain. She turned away from the finished food, trying to hear something. She heard nothing. No doubt magecraft that was being used so she didn't 'overhear' them. Thankfully, she put a recorder beneath a pillow to record their conversation.

She can see what happened later.

Still, it was becoming clear things were only going to get more dangerous. Sakura felt she had to do something. Anything. But what could she do?

Her brother had her Servant, and Sakura knew no magecraft. Ever since this war started, all she could do was watch as her senpai kept coming home with more injuries. Doing nothing but feed him and offer him a smile, nothing more. She wanted to do more than just that. Maybe this 'aura' thing she heard from her recorder a few days ago could help.

What was it that Ozpin guy said again? That those with aura can unlock others aura's. In that case, maybe she can ask Rider to see how that worked, and have her brother unlock her aura. That way, she can help senpai. Yes, that sounded right.

Clink.

Sakura blinked, as she heard a strange noise. She then saw it was just a cup that had fallen over. She quickly grabbed it and put it back upright. Though as she did so, she saw a small spider. It wasn't very big, and has a black body with white markings on it's back. Though what made it odd was that it seemed to have glowing red eyes, and for a moment Sakura thought she heard it growl.

Must be her imagination. Regardless, Sakura then decided to go to her room for a bit to relax. She'll bring the food to the others soon. Not noticing the Grimm's eyes glowing red as it then hissed before following after her. As it sensed her negative emotions.

Seems Ozpin's not in trouble, but he's definitely being looked on with suspicion. Not to mention Sakura may be in trouble as well, especially since she'll be very upset when she learns more information due to her playing it smart and leaving technology to get her answers. That'll make her emotions unstable.

But until then, Shirou decides to leave for a bit for relaxation, only for trouble to rear its ugly head against him. He'll probably be fine.
