[X] Follow the path to Marisa's house.
You float up until you're at Archer's level. "Hey, Tohsaka is still with Marisa, right?" He frowns at you.
"Yes, Rin is still working with her."
"Has her collection improved?" Archer winces at Remilia's question, and you're not alone in looking quizzically at her.
"Milady?" Remilia waves her hand dismissively.
"I went to see if she had anything worth buying. An awful mess, I cannot imagine what anyone with any organizational sense would do if they were forced to live there." Archer shakes his head. You drop back to the ground.
"Did you get anything? From Marisa?" Remilia smiles and shakes her head.
"No, I did not. She does not sell much of her collection - it seems it is difficult for her to part even with useless trinkets - and what she can make is not worth the purchase." She sighs. "I suppose we shall be going to see her now?" You grin and look at the others hopefully.
"Marisa is human, right? It would be interesting to see what mages here are like." Vita looks at Fate for a moment, then turns back to you.
"Marisa was the one who shot you with the giant laser, right? Yeah, let's go see her!" She turns toward the paths - and trips. You blink, more than a little surprised, and Lulu and Agito hurry forward to help her up. Ilya starts walking down the brambly path.
"Come on, Tribbler! Let's go see Rin." Vita fumes, but Nanoha pats her shoulder until she heaves a sigh, and the rest of you follow Ilya.
"Is that normal? The leaves, I mean?" Remilia blinks and looks around, then raises an eyebrow at Fate's question.
"Yes. As summer turns to autumn and progresses toward winter, the leaves of the trees turn from green to a fiery collection of reds, golds, and oranges. And then, after a short time as autumn leaves, they fall to the ground. Do you not have seasons in Mid-Childa, or are you simply only familiar with the so-called evergreen trees?" Fate blushes and, amusingly enough, pouts as Nanoha fails to hold back a quiet laugh.
"What Fate-chan was asking about was the sudden change. All the trees went from being completely green to being completely autumn-colored. It's like the season stopped at a border." Remilia nods.
"Oh, that. The goddess who colors the leaves is small, weak, and unimportant, and she paints the leaves with her magic almost individually. And I believe she lives on Youkai Mountain, so her work progresses unevenly. I am sure she has a name … Sakuya, do you recall it?" Megane frowns and shakes her head.
"You have a goddess who's in charge of making sure leaves change color? It's a natural process, though -!" Berserker appears next to Ilya, who adopts a defensive posture, and that is enough for Vita and Zest to move to cover their dependents - but even as their Barrier Jackets finish materializing, Ilya relaxes and frowns. Remilia coughs and Ilya, startled, turns to face everyone, a light blush spreading across her face.
"Uh, um, sorry. It's just - Archer just came tearing past, so I thought -" Ilya flinches at the sound of an explosion, and everyone looks down the path to Marisa's house. Nanoha and Fate both transform and leap into the air, and Remilia sighs as they fly toward the sound with Vita just behind them.
"Sakuya, make sure they do nothing stupid." Sakuya bows and vanishes, and Megane frowns at your sister. Remilia just waves her hand dismissively and resumes walking, however. "Rin, Archer, and Marisa are all unharmed. I suppose a majority wishes to see what happened immediately, however?" Megane, Zest, Agito, and even Kyouko all nod, and she sighs. After a moment, she produces a sheet of paper, quickly writes something on it with magic, and folds it before holding it up. A few seconds pass - and the air above her hand zips open and a hand reaches through, grabbing the note and taking it elsewhere. What happened that would get Yukari involved?
"Uh, so what's going on?" You glance at Kyouko just as numerous hands reach forward to grab your sister - and Ilya, and Berserker, and everyone else. And then you're standing in front of Marisa's house. Most of it, anyway - the right side has a rather large chunk taken out of the roof and walls.
"There are still four more, but they are flying. If you relax the barrier, they should be here momentarily." You turn away to see Yukari and Ran standing together, and beyond them are Marisa, Tohsaka, and Archer. The Servant has his bow out and drawn, and is aiming at Yukari. Ran half-bows to Remilia, and a few seconds later Nanoha and the others fly over, seemingly perplexed by your appearance. Sakuya, however, drops down and produces a parasol, although she keeps it closed. "Thank you. Now, in the interest of not having to figure out whether I need to fight against you to defend Marisa's guests, would you mind explaining what happened?" Yukari half-turns to face you and Remilia, and Ran turns to face Archer. Marisa looks quite angry, and her hand is holding her mini-hakkero, but Tohsaka looks confused and worried … and a little worse for the wear. Did she get hit by the explosion?
"These two have directly threatened Gensokyo," Yukari begins, and Marisa leaps to her feet.
"That's a lie! We didn't do anything dangerous!" Remilia presses her face into one hand and squeezes around her eyes, and Yukari produces a strange sword. Its hilt is nothing but a flat cylinder, and the 'blade' is rounded, without an edge. Remilia looks up and shakes her head, then walks up to take the strange weapon from Yukari.
"The Jewel Sword? Did you really make it?" Ilya sounds more curious than anything else, and Berserker is gone. Marisa helps Tohsaka to her feet, but the younger mage seems a bit unsteady - and then Lulu and Megane walk toward her.
"In a sense, yes, they did make Zelretch's tool. It is, however, flawed. Is this the first one you made?" Marisa shakes her head, and Archer finally lowers his bow as Megane crosses in front of him. With that advantage removed, he simply wills the bow away and turns to help his Master.
"No, it's the fifth. But the others didn't work." Remilia snorts derisively.
"I suspect they do work. And Yukari is correct - you nearly did do significant damage to Gensokyo with this one." She keeps looking down at it for a few seconds before looking up at Yukari. "Do you want to deal with it, see it destroyed, or do you trust me to dispose of it safely?" Yukari stares at her for a long moment, then dips her head.
"… I will trust you to dispose of it without further harm to Gensokyo, Remilia Scarlet." Then she turns and walks into a gap, while hands pull her familiar into another. Nanoha, Fate, and Vita dismiss their Barrier Jackets, and after a few seconds of relatively awkward silence, Marisa walks over to pick up her hat, brushing it off as Sakuya opens the parasol for Remilia and looks questioningly at you.
"Man, I forgot how bad she could be when she gets angry. Gonna have to update my grimoire." She shoves her hat down onto her head before bouncing back to Tohsaka. "So how is she?" Megane sighs and stands up.
"I'm fine, just - ooh, everything aches. What hit me?" Archer gingerly picks her up.
"Ran. That fox youkai." Tohsaka shakes her head, then groans in pain.
"Ooh! No - I mean … what did she hit me with? First … first they showed up, and then -" She carefully presses against the side of her head and stares at something. Marisa frowns worriedly.
"Uh, she hit you. She might have used some kind of attack magic that I missed, but it looked like she just knocked you over." She shakes her head and waves everyone toward her home. "Anyway, everyone, come on in. Don't wanna be a bad hostess or anything, and I guess I've got the space now, anyway." She picks up her broomstick and hurries to the door, holding it open for everyone.
Archer sets Tohsaka down on a long chair instead of taking her to a bed, but from the look on his face it seems that it's not his decision. "Ugh. Remilia. You said -" Remilia waves her off and looks around, although you notice that she hasn't put the sword away, instead keeping a tight grip on it. Marisa's house is quite clean, and she chuckles when your sister looks at her.
"Hehe. Guess a Servant is a servant, too, huh?" Remilia shakes her head before turning back to Tohsaka.
"The Second Magic does not work here as it does in your world, Rin Tohsaka. Do not argue with me, girl, or otherwise test my patience at the moment. The only reason I have not struck you for your stupidity is because I may find it too enjoyable to stop." Color slowly drains from Tohsaka's face, and Marisa steps between Archer and your sister before either can get too worked up.
"So, uh, what did happen? I mean, did it start eating the Barrier, or something?" Remilia sighs and looks at the crystalline weapon.
"No, it did not. It breached this dimensions, reached another, and drew energy from that place. It simply also brought something else. It is currently locked within the sword, stuck in a non-physical state, but another successful activation could release it, or allow it to break free. And should that happen, it will likely destroy half of Gensokyo before enough power to destroy it can be brought to bear." She sighs again. "Of course, it could kill us all, too. I will not rule that out." Nanoha and Fate look at each other, but you don't see the worry or nervousness you'd expected. Lulu looks worried, and Vita and Megane and Agito, but not Nanoha and Fate. Ilya doesn't look worried, either, but she has her expressionless mask up, so she probably is worried.
What do you do?
[ ] Offer to destroy it. After all, you are the one who asked for Tohsaka to come here and introduced her to Marisa, so you're at least a little to blame.
[ ] Tell Remilia to go deal with it now so she isn't bothered by it. You can keep everyone together until she gets back.
[ ] Other?
