Really? Those over there—
(cocks her head towards the weapon rack)
—are just ordinary katanas. They can't cut through space and time, if you've been wondering about mugging me for them. Oh, and I've got a suit of armor over there, though I don't think he'll like it if you tried stealing him.
(Geki is watching Vergil carefully, making sure he doesn't step too deep into the smithy or get too close to Mura for comfort)
Thanks for the courtesy. But, again, I'll have to politely refuse. It's more a personal code than anything else.
(kneels down to withdraw the blue blade embedded in the ground, the one Vergil threw)
Besides, the ones you already have aren't bad. I'm sure you'll go a long way with them.
(then, she stands back up and twirls it around a bit in her prosthetic hand, before offering it to him hilt-first)
(even if she's certain it's a phantom sword that'll vanish into mana once its role is done, she figures the gesture won't hurt)
-His expression grows more stern (if that's even possible) as he eyes the spectral sword being handed back to him-
....Power hidden away is wasted. It should be used productively. For a just cause.
-He looks up at her, dead in the eye-
If I am to accomplish my goal, I need more power. If you will not show me what you possess....then I'll force your hand.
-Mura can feel the energy within the phantom sword suddenly grow volatile and unstable....-
-It's going to explode!-
...
(Mura heaves a Deep, Exasperated Sigh, as her Servant garb materializes around her and a blood-red katana materializes in her left hand)
Fine. But if we're going to do this, let's take it outside.
(and in the blink of an eye, she lunges forward towards Vergil, thrusting at his chest)
Juuchi Yosamu!
(whether or not Mura's thrust connects or is parried away, something is certain... space is warping around her and Vergil)
(they're not in the basement anymore, but rather by the lakeside!)
(right as soon as this warp finishes, Mura tosses the about-to-explode sword into the lake so it can detonate with minimal damage to the surroundings)
....!
-Vergil draws his sword in the blink of an eye to clash against the incoming thrust, glancing around at the warping space, and the sudden change of location-
....Well....Look at that. You were hiding something special.
-Cori hears a loud SHUNK, and then a small whistling noise, and feels a sinking sensation-
-.....Well, it seems someone's thrown a glowing sword into your floatie. That's incredibly ru- -
-boom-
(smirks, as she puts both hands on Juuchi Yosamu's hilt and keeps up a blade lock with Vergil)
Like I said, it's not for sale. Think of it as a self-defense tool against people like you, if you get what I—
(in the middle of her banter she summons two flying, non-blood-red katanas a couple meters above Vergil's head, which fly towards him tip-first)

Mura's Forge
...Funny. You don't seem to mind putting your hands on others' things yourself.
-A translucent blue sword flies out from the shadows, embedding itself right at Mura's feet-
