"We'll arrive at the next location and switch cars in fifteen minutes, Ms. Henriikka." Clown drove through the alleys of Shinto, taking obscure paths on the way to a lot where they'd switch cars and then head to a boat they would take to Miyama Town. Since the bridge connecting the two halves of the city was obliterated, multiple ferries were set up to transport people across the river.

Henriikka sat in the back seat looking at a dozen thin floating screens of crystal displaying all that the Edelfelt mage's familiars saw. While Henriikka monitored the city, Clown kept them moving. They couldn't risk staying stationary in case Lancer was still tracking them.

The images on most of the screens were of various members of the Fujimura Group. Henriikka wanted to gather as much intel as possible on the yakuza who had captured Luvia. Henriikka couldn't believe her sister had been so reckless that she actually got captured by an enemy Master, and of course it was one with a makeshift army on their side. It was hard to believe Henriikka and Luvia were sisters with how different they acted, and how different they looked for that matter. Henriikka was Luvia's identical twin, but that didn't mean the sisters looked exactly the same. To start off, Henriikka's sedentary lifestyle made her plumper than her sibling and instead of Luvia's penchant for fancy dresses, Henriikka wore comfy sweatpants and hoodies. Henriikka's hair was a long tangle of blonde hair unlike the precisely styled ringlets that Luvia had. Unlike her sister, Henriikka didn't waste time on appearances that only gathered unwanted attention.

Luvia was so boisterous and show-offy and so it was obvious that her personality would get her into trouble when the Holy Grail War began. It was supposed to be a battle of stealth and deception and Luvia decided it would be a good idea to create a giant Bounded Field in the city that pulsed magical energy which would alert everyone of where she was. She also thought it was a good idea to take on the head of the Tohsaka family in a direct one-on-one confrontation when she could have easily set things up so she and Clown ganged up on and killed her and then moved on to doing the same with Sakura. It would have been easy, but Luvia's stupid Edelfelt pride or whatever got in the way. This was why Henriikka knew she was right to always stay at home all the time rather than let herself get dragged along by her sister into whatever nonsense she would get into next. It was better to stay in the castle and relax all day reading.

A spike in magical energy. Henriikka pulled out an amethyst and tossed it into the air where it turned into yet another screen. The image presented was of Sakura Tohsaka who had something she wanted to talk about, likely something related to the events of the night. It was nearly morning and Caster had reported in saying they were done working with Assassin for the night and that they would share details once they returned. It looks like Sakura's Servant was a bit more impatient and already told her Master the details telepathically.

"Hello, Sakura Tohsaka."

"Hello. How are you?"

"Fine, how are you?"

"I'm doing okay. Have you spoken with Caster yet?"

"No. I assume you wish to discuss tonight's events?"

"That's correct, but if you haven't been updated yet, I can wait."

"Just inform me yourself."

"Oh, duh, sorry." Sakura then proceeded to explain what had happened when Caster, Saber, and Assassin convened, about how they discussed Assassin's nature as a Counter Guardian and the bizarre nature of this Holy Grail War. Sakura also spoke of how they found the Einzbern Castle which currently housed multiple Servants and Masters. Sakura even spoke of the plan Assassin had concocted that would eliminate the many threats present in the Einzbern group. The night had ended up being more eventful than anticipated.

"This could work out well for us. Assassin's plan is solid, though I feel he may be rushing into things when it would be better to spend more time preparing." Henriikka blew out of the side of her mouth to push a lock of hair out of her face. "But there's nothing we can do as long as we're at the whims of Assassin and his Master so we'll go along with it for now and hope the fight goes in our favor."

"And this actually provides us with an opportunity."

"What do you mean?"

"Assassin's plan will force him and ninety-nine percent of the yakuza to be far away from the Fujimura Mansion. Assassin's Master will probably still be there along with a few yakuza, but not much else."

"And what does that matter?"

"This is the perfect time to sneak in and rescue Rin and Luviagelita! While Saber and Caster are with Assassin and he thinks we won't do anything, we sneak into the mansion and save our sisters!"

"What?" That was an idea so asinine that even Luvia wouldn't have suggested it. The risks involved with infiltrating an enemy Master's base without a Servant of their own was astronomical. Well, they weren't technically without a Servant, but that was still a backup and they hadn't done nearly enough intel gathering. They still didn't even know if Assassin's Master was a magus or not. This plan of Assassin's may have appeared like a perfect opportunity to turn the tables, but that was only if one disregarded the greater complexities of the situation. "Out of the question. We aren't going to try and bust into the Fujimura Mansion without a real plan and without much more information on our enemy."

"But we might not get another chance like this. The longer we wait around and waste time, the more we risk Rin and Luvia getting killed before we can save them."

"We aren't wasting time. We're preparing."

"But for how long?"

"I told Saber when we first became partners, at least a week."

"It's just about to be day three!" Sakura arms shot out in different directions. "So much has happened in just two days, who knows what could go wrong if we don't act right now!"

"And what will you do if you come face to face with Assassin's Master and they're stronger than you? What if you end up in a situation where you have to carry both Rin and Luvia out of the mansion on your own while getting attacked?"

"That could end up happening even if we do make plans and have extra information, and we can't plan for literally everything, that's ridiculous!"

"Of course we can't plan for everything, but we can take action to mitigate the amount of unknown variables to make as informed a decision as possible." Henriikka scratched at the seat next to her with her fingernail. What was so difficult for this girl to understand about not rushing into things without proper precautions?

"But we don't have the time to make those precautions!" Sakura balled up her hands into fists. "Our sister could get killed whenever Assassin or his Master decide they aren't useful anymore! Assassin might kill them after tomorrow's plan! He might think he got all the use out of Caster and Saber that he could and so it's best to kill them by getting rid of their mana supplies! Archer and the other Sabers are the biggest threats in this war, so once they're gone, it'll be smooth sailing for someone as skilled at assassination as Assassin!"

"There's still Lancer. He may want to wait to take her out."

"If she's still alive, she might not be, Hell, she probably isn't!"

"Assassin is cautious, he won't get rid of any tenuous advantages he has until he knows for sure they aren't necessary. Until Lancer's confirmed dead, he won't kill Rin and Luvia."

"But the Einzberns are the ones who provide the vessels for the Greater Grail during the Holy Grail War and Assassin plans to capture one of the Einzbern homunculi rather than kill them so the Grail is still usable!"

"And?"

"He's going to interrogate the homunculi as to how many Heroic Spirits they've absorbed into them so far and which classes those Heroic Spirits were. It isn't definite that they'll know the classes, but if they do know and one of them is Lancer, then that'll be it! If we don't act tomorrow then it could be too late!" That theory was a worst case scenario, but Sakura had actually made a decent point. If it turns out all the key player Servants are dead, then Assassin can just kill Luvia and Rin under the assumption that it'll kill Caster and Saber. From there, he could just track and assassinate all the remaining servants one by one. Assassin is pragmatic enough to do such a thing, though he'd be making a mistake since Saber is currently contracted with Sakura, not just Rin. Should they tell Assassin about Saber's new contract-wait, no, then he'd know Rin was a useless bargaining chip and maybe kill her. Sakura wouldn't go for that. Perhaps they could convince Assassin not to risk getting rid of his strongest allies when he doesn't know the strength of the remaining Servants. There was always the chance that Rider and Berserker were also exceptionally powerful, but that ran off the assumption that they were both still alive. It could turn out Assassin, Caster and Saber will be the only classes still in play after today.

Henriikka thought Sakura was being impatient, but she was actually reasonably concerned. The Edelfelt magus scratched at the seat more as she tried to think of a safe solution that wouldn't involve fighting so soon. She wracked her brain like she hadn't in a long time, but she couldn't think of anything reasonable.

The mage's mind shifted to what the consequences would be for inaction, the answer being the loss of Luvia and Rin. Henriikka didn't care about Rin, but losing Luvia was a different matter. Sure, Luvia was annoying, pretentious, greedy, obnoxious, petulant, violent, rude, and whole bunch of other things that made Henriikka feel the veins in her head pulse, but those things didn't change the fact that Henriikka still cared about her sister.

Luvia had always been the one to push Henriikka to be more open, and though Henriikka found it annoying and rarely heeded her sister's advice and requests, she still appreciated that her sister was trying to help her. Luvia truly cared about Henriikka. She was the one who would defend Henriikka when others tried to bully her when they were little kids and it was Luvia who would always praise Henriikka for all her strengths that would get overlooked by others due to her introverted nature.

Henriikka loved her sister. She didn't want Luvia to die and it seemed that now was the time to prove it. That meant telling Sakura about what she had been hiding from her.

"You're right. We need to infiltrate the Einzbern Mansion."

"Wait, really? You agree?"

"Yes. You convinced me."

"Great! Now we just need to start planning for it! We don't have a lot of time!"

"First, there is something I have to tell you about. I have my own Servant."

Sakura's whole body went a bit limp as she took a second to process the new information. "What?"

"I have my own Servant. I'm a Master." Henriikka looked at the Command Spells on the back of her hand.

"You've been a Master this whole time? I thought you were in Fuyuki just to help your sister win the war."

"That isn't wrong. Luvia was the one who wanted to join the war and win it for the Edelfelt name. I just got dragged into it due to us having the Sisters Sorcery Trait. It lets both my sister and I act as Masters taking up the same 'Master slot' in the war. We both get a Servant, but they're both in the same class and are two versions of the same Heroic Spirit."

"So you've secretly had another Caster with you? Another version of the Gorgon Sisters? Then why didn't you help your sister fight us?"

"My sister wanted to start confronting other Masters immediately while I wanted to wait and gather information. Neither of us was going to budge so we decided to work separately from each other, but still on the same side. Considering how things went, I'd say I was right and my sister was wrong." Henriikka said smugly. "Anyway things have forced my hand so I'm going to have to show my hidden trump card. My Caster and Clown will go with you to infiltrate the Fujimura Group's compound. I'll also provide you with plenty of gems you can use for your magecraft. Caster will be able to sneak you all through the Bounded Field undetected and locate Luvia and Rin. When you find them, Clown will be able to teleport you all out of there with his spatial swapping Bounded Fields. If all goes well, you'll be in and out in a flash with nary a wound and our sisters in tow."

"That sounds perfect! The only thing we'll have to worry about is any yakuza we run into along the way. How good is your Caster in a fight?"

"Better than most Casters, so we should be fine against random yakuza or magi."

"They're more than that." Sakura's shoulder moved up and down and bit as her countenance became more grim. "Assassin uses projection magecraft to counterfeit Noble Phantasms which he plans to arm all the yakuza with for when we attack tomorrow. He'll probably give all the yakuza at their base Noble Phantasms too just in case they get attacked while he's gone."

"That's bad. Depending on the competency of these yakuza and what Noble Phantasms they're given, they could kill Caster. You'll need to be careful and kill everyone you have to if you can't sneak around the guards. Any hesitation or mercy could lead to those thugs killing all of you."

"I understand." Sakura didn't appear all that bothered with potentially needing to kill people. She may not have looked like it, but she could be cold-hearted when she wanted to.

"Good. Now, tell me more of the details of Assassin's plan so we can work around it."

"Right."

The two Masters strategized for their assault that would only take place a few hours later. So much was riding on it and so much could go wrong. They needed to be prepared for anything and everything, but the time necessary for such preparations was a luxury these magi lacked. They had to simply have faith that things would work out. It was in Henriikka's experience that things rarely worked out, so she felt her heart grow heavy as she prepared for the eventuality that she alone would be returning to Finland and would have to take up the mantle of family head.
