Obake Itoko Chapter 10: My Bot Knows What You Did In The Dark, a big hero 6 fanfic

Chapter 10, everybody! Time to lock and load….

Posting this a little late in the day (or stinking-early in the morning), but I've spent the past three days marathoning a really good Harry Potter fanfiction—it's called "Realizations," it's by Wishweaver here on FFN, and while it's unfinished and hasn't been updated since 2010, it stops in a real comfy place so it's a worthwhile investment. :)

Also in retrospect I recall that Hiro did about 100% of this on the computer, but these two plotting over notes was too much fun writing to pass up. :D Onigiri, for those who might not know, are rice balls—or jelly donuts, if you're a '90s 4kids dub. *bricked*

Onigiri is also recognized by Microsoft Word how….Also, was in the store yesterday and during the checkout line, it occurred to me that Hiro asking for gummi bears might have stemmed from just how many other candies may or may not contain peanuts—which Hiro is allergic to.

The Authverlord, thanks for the review! Yes…and yes—and yes. We can't say that Obake's not motivated though.

It was a tiny bit frustrating having to put their mad designing on hold for dinner—Hiro finally convinced Aunt Cass to let them eat upstairs, they had this really awesome idea and you can't just stop in the middle of a really awesome idea then it escapes and you never get it back and you know how that is.

Aunt Cass finally relented, looking bemused as she put two plates down on the floor next to them.

"So what is this really awesome idea?" she asked, looking around at the papers scattered everywhere.

"Still in the planning stages," Hiro evaded, shooing Mochi away from the plates. "Gotta get it all copied down before it gets away."

She shrugged, scooped up Mochi and went back downstairs—Hiro had a moment of silence and popped a dumpling in his mouth before getting back to work.

"So," he said, in response to Obake writing down tell me about the microbots. "They're pretty straightforward—they're all controlled by this neurotransmitter—" Aha. "And I bet you that it's behind that kabuki mask! So we get the mask, the guy loses control over the microbots—game over."

Obake nodded, wrote a new line: so how do WE get the mask?

"Now that—is an excellent question."

Which was how they spent the rest of the evening—they had one goal: get the mask. There were a ton of microbots that could stop them in a million ways between them and that goal. Hiro had made the microbots with the intent that they wouldn't be easily stopped.

It was aggravating, really, when your genius was turned against you.

Aunt Cass finally came up and ordered them to pick this mess up and get into bed, despite Hiro's protests, it's ONE O' CLOCK, get to bed! Made sure they were in bed before tucking them in, giving Hiro a kiss, watching from the stairs for a moment before going back down.

Hiro waited, giving Aunt Cass enough time to get in the bathroom and then in her own bed…sat up and threw his pillow at Obake. Jump out of bed, dig in one of the nearby drawers, slip back over the bed to the other side, where Obake had the plans laid back out.

"Okay," Hiro said, tugging the blanket over them to hide their shapes better before clicking the flashlight on. "Where were we?"

Obake immediately scribbled in his design plan.

"No," Hiro said, just as quickly scribbling it out. "No spikes, I have one 3D printer and we're trying to hurry back over there and catch this guy, so quick and dirty design. We can have spikes in version 2.0."

Obake huffed, scribbled down a few other ideas for Hiro to run with—had to frequently remind himself that they needed to have a design that could be machined up quickly—Mr. Kabuki Mask knew he was discovered, they needed to nail him fast before he scurried off. Ignore Baymax when he told them just how late it was—right now he was a boy on a mission. They both were, if Obake's own intenseness was anything to go by.

That guy would never know what hit him.

Cass checked her watch, put her bookmark in her book…frowned at the ceiling. Sure, the boys were probably in bed…but she knew that look Hiro had had—he was on a tear about something and wouldn't stop until it petered out. It was something he and Tadashi both did, and it was nice that he was getting some…some energy back…but at the same time….

She sighed, apologized to Mochi as she crawled out of bed, snuck up the stairs to peek in…saw a flashlight light on the other side of Hiro's bed.

"Hello," Baymax greeted as Cass turned the lights on. "Hiro and Obake are: asleep."

"Is this a recent development, or are they just pretending?" she asked, walking over to check—blanket from Hiro's bed draped over to act as a makeshift tent…and both boys were conked out over what looked like robot designs, all sorts of notations scribbled everywhere.

"This was a: recent development," Baymax said, as Cass got some pillows. Tuck one under Hiro's head, was treated to him mumbling just visualizing internally; pull the flashlight out of his grasp and turn it off, setting it aside. Tuck the other pillow under Obake's head, didn't get much in the way of noise from him. Hesitate…put a hand on his chest, wait for it to rise and fall. Okay, that was good…he had been through a lot, according to Baymax.

They all had.

Tug the blanket down, tuck it around the boys…ruffle their hair one last time before heading back down to her own bed. "Good night, Baymax."

"Good night, Aunt Cass."

Hiro woke up to a pillow under his head, which was an improvement over drooling on their plans.

The bad news: the light filtering in meant it was morning—specifically, Sunday morning, when Aunt Cass didn't have the café open and would be more inclined to sleep in and let them do so as well.

Hiro shoved up, shook Obake awake. "Wake up, we've got work to do!"

Obake groused, rolled upright, one eye blinking blearily—

Scrambled the rest of the way up as he too recalled what it was they were doing.

Hiro sped through personal hygiene, told Obake to hurry up with his as he scooped up the notations from last night, told him he'd be in the garage, come on, Baymax—

Was temporarily detained by Aunt Cass.

"Sorry Aunt Cass, we're—" he started.

"I know, I know, on a roll with something, food to go," she said, handing Baymax a plate with breakfast rolls and a couple of single-serve bottles of milk. "Make sure they eat, okay? Make sure you eat something, your brain won't work on an empty stomach."

"Regular meals assist with cognitive brain functions, as well as improving one's mood," Baymax agreed.

"Uh…sure. We might be going for a walk later too—pretty sure that helps with everything," Hiro said, feeling for the garage door—might as well set up an excuse for bad-guy-hunting later.

"Exercise has many health benefits, in addition to improving one's mental function."

Aunt Cass gave Hiro one of those looks. "Is there something you ought to be telling me?"

"Yes," Baymax said—

"YES!" Hiro interjected, putting himself bodily between Baymax and Aunt Cass. "Um…I love you, Aunt Cass."

Probably the right thing to say, considering the aw and the hug. "I love you too," she said, letting go to look at him. "Just don't work yourself to death, okay?"

Hiro winced at the wording. "Um, sure."

"Okay—last hug."

"Aunt Cass."

Obake was in the garage shortly afterwards—Hiro put on some Fall Out Boy and turned up the volume a little to be heard over the sound of Aunt Cass vacuuming.

"Okay," Hiro said, shoving away from the little boom box as the first strands of music started. "Next up is coding a fighting chip for Baymax and programming the 3D printer—who wants to do what?"

They ended up flipping for it—Hiro reminded Obake that they didn't have time for spikes as he pointed the printer and nearby computer out.

In the meantime—crack his knuckles, pop in a fresh chip, download a bunch of karate movies and use motion tracker to upload the different moves. Moment of silence and munch on a breakfast roll when Baymax insisted—scowl when he realized it had the liver and spinach sausage in it. Oh come on.

"This one is yours," Hiro said, depositing the breakfast roll next to Obake, who scowled at it—probably because it had a bite missing. "How're we doing?"

Obake indicated the first piece he had pulled out. "Excellent," Hiro said, grabbing it and taking it to the sander. "Keep 'em coming."

That took most of the afternoon, and saw them sometimes swapping jobs or checking in on the fighting chip—Obake was actually really good at smoothing out any kinks in the programming, as it turned out, and the only break they took was Aunt Cass depositing some lemonade and onigiri on a nearby table.

"Okay, so we should be close," Hiro said, running to get the next piece out of the printer.

"Hiro," Baymax said. "It has been several days since you requested a reminder for—"

"Yeah yeah Baymax whatever," Hiro said, pausing to poke him in the belly. "Think we're finally ready to do something about this."

Baymax actually seemed confused about that, considering the next time Hiro glanced at him he was poking where Hiro had. Oh well. Finish up the last piece, glance at Obake—got a thumbs up.

Hiro grinned, hefted the first piece. "Baymax? Let's get dangerous."

So as it turns out, stuffing a marshmallow into armor was a bit more harrowing than first implied.

But finally—finally—the fruits of their labor was standing before them.

"I have concerns," Baymax said, looking down at himself. "This may undermine my nonthreatening and huggable appearance."

"That's the idea, buddy," Hiro said, batting away the note Obake had written about I told you about the spikes. "I told you, spikes are version 2.0. Is the chip ready?"

Obake held up a chip with a skull and crossbones sketched on it—perfect. Take it, walk up to Baymax, tap on his chip bay—

Hesitate at the sight of the green one.

Tadashi's chip, the heart of Baymax—the last thing Tadashi had left him.

This is for you, big brother, he thought, swallowing hard before plugging in the red chip and pushing it in.

Baymax blinked, processing the new information. "New data packet received. Extracting information…." Look at Hiro. "I fail to see how information on: fighting, improves my performance as a health-care companion."

"You want to keep us healthy, don't you?" Hiro asked, shrugging before holding out a board. "Now punch this."

What followed was similar to two nights ago, where they set up increasingly elaborate combinations for Baymax to attack, going through as many of his new fight moves as possible—while breaking for some gummi bears, ostensibly to check his control. The sugar was a bonus.

Definitely added some extra bounce to his cheering when Obake looked up from his list and gave him a thumbs-up. "YES! FIST BUMP!"

Baymax looked at the proffered fist. "Fist bump: is not in my fighting database."

"Uh, no—it's…a thing you do. When you're excited." Show him how to do it, blow it up at the end—couldn't help the snort at Baymax's ba-la-la-la, his attempt at copying the explosion noise.

"You too," he said, bouncing over to Obake and socking him in the arm before holding his fist up again. "Should be easy, right? You just saw Baymax do it."

Obake made a face at him, considered…finally humored him.

"Yes," Hiro hissed, unable to keep the spring from his step. "So we're ready?"

He dug out the petri dish when Obake nodded and tossed the clipboard away. Check it—still resolutely tapping against the glass, trying to get somewhere.

He was grinning when he looked up at the boy and the bot sharing the garage.

"Let's get this guy."
