Somehow Nitori managed to stop talking long enough for me to actually get some words in. I have a basic idea in my head, but I get the feeling that this will end up being more complicated that I think. "On the most basic level, I want to be able to reconfigure what these will be used for for any given purpose. Sort of like a Swiss Army Knife, but in cannon form." I start to sketch down some of the ideas I have, but one of the most prominent is a sort of a 'Reconfiguration Drone' setup. It uses a crystal as a battery/core, another for the lens, and a rewritable rune surface that changes according to what I need at the time. Things like refraction lenses, defensive shields, offensive cannons are all on the menu, and they change shape into what would make the most sense for the given configuration. "It's a jack of all trades deal, but I like keeping my options open."
"Heh, never were one for straight up power, were you?" Marisa chuckles as she looks over the designs. "Still, it's a good thing you decided to share this with us, otherwise these would have blown up on you for sure. Just look at how you've got the mode change set up! These'd break apart in maybe six uses if they didn't detonate first." She then takes a piece of paper for herself and starts to scribble down a magic circle that looks like it could be reconfigured into any number of meanings without much effort. "See, something like this would work a lot better. It'd mean your cannons wouldn't look so flashy, but this symbol would be nice and stable. Plus it'd let you reconfigure on the fly if you made it so they go like this." She then scribbles down a rough design. It's clear that she hasn't put too much thought into the back of it, but the front consists of a shell that's made up of a number of free-floating circles that look like they'd be capable of seperating and relocking at will.
"Who says it can't look good too? You just gotta be able to fit the circle onto it, right? So pick a spot and I can figure something out to make it work!" Nitori seems more than happy to pitch in her own ideas, and she manages to surprise me by placing a model of her idea on the table. "Size doesn't matter too much does it? You're only looking at a few reconfigurations. Or if you are, you can use multiple circles to do the job." She helpfully points out a possibility that I don't think Marisa had considered. Perhaps...
"Maybe if I didn't use circles, but runes? If applied correctly you can make them state what you want quite clearly, and the possible reconfiguration method would let you change where you'd have to stick them." I start to sketch down my idea even as I speak, detailing a possible chassis-based mode change. "Putting a magic circle in front just screams 'I'm a weak point, come destroy me!' Putting that kind of thing where it's not so obvious would be better." Something then comes to mind. "And if runes were used, there might not be a need for the whole rotating wheel deal. Maybe you could apply power only to the runes you wanted to use?"
Marisa shrugs as she thinks it over. "Yeah, but that'd be just as big a weak point as a magic circle. It probably would be better not to stick that sort of thing within easy reach though, so maybe use the forward shell arrangement, but stick everything on the underside of it?" She keeps sketching her ideas out as she talks, and it's obvious she's coming up with more than just that one idea and form.
"Who says it's got to be visible at all? You could write them in the gem casing and it wouldn't matter so long as you gave it proper shielding. Runes are pretty forgiving that way, unless I really got it wrong." Nitori brings up yet another possible idea. There's this silly little thing where if you were to damage a rune/magic circle heavily enough it would either cease to function, have its function changed, or explode outright. Given my luck, it's probably going to be that last one, and it will probably be a really big explosion that lands me back in Eientei for the next few days. Sticking it where the enemy would have to destroy the cannon anyway just to get at it might be an idea as explosions tend to not take all that long to go off... Ugh, why am I considering this? These are supposed to be useful for as long as I can keep repairing them, not to use them as bombs.
"Are you nuts? Even with proper shielding, if you went for a rune type that activates when power is applied and stuck it next to a power source, you'd never be able to shut them down! Trust me, I've tried that sort of thing before." Marisa rolls her eyes as she recalls an incident that might not have been so different from my own screw-ups. "You'd make it permanently confused as to what it's supposed to do, and it'd either shut down or blow up. I don't know about you, but I'm kinda tired of Ivan almost killing himself all the time."
"Second layer of shielding then? They'd be heavier, but if they're floating around on their own that sort of thing won't be an issue to begin with." Nitori then proceeds to come up with a blueprint for an orbital cannon that looks rather high-tech, almost to the point where it's more like something out of science fiction rather than anything sensible. Yet even I can tell it's something well thought out and more than capable of working. "Plus, this design would give you all sorts of awesome things! They could form barriers at a moments notice, bounce danmaku, suck up elements for later and to mitigate attacks, and you could even turn it into a really awesome cannon! Plus, it'll call for seven since they'll use a hectogon shaped shield and you need enough to cover your whole body, and you could redirect them to guard against anything in any way you want! Plus it can be upgraded and given all sorts of modular equipment! It's perfect!"
"So, you're going to get started on this straigh away while Nitori's still here? I'd be willing to pitch in too if you want." Marisa kind of surprises me with such a hitch free offer, but I figure I should hear the rest of it. "You just gotta make me lunch first, I'm kinda hungry."
[X]You know what they say, the more the merrier. ...And less likely to blow himself up.
[X]Letty gave you insight before, maybe working on something like this might trigger something else?
[X]...Check the door before you forget.
