A/N: Just a heads up this is a Undertale au/crossover/rip-off whatever you want to call it. I just want to clarify that none of the characters from Undertale show up in this. The only thing I took from Undertale is the setting and bits and pieces of the plot. In other words, this isn't a meme or a joke, I'm 100% serious. Here's my extremely self indulgent undertale/danganronpa mash-up fic. Enjoy!

Shuichi was watering his garden when the human girl fell from the sky.

It happened so suddenly, he wasn't sure if it had happened at all. His attention had been absorbed in his own daily chore, mindlessly watering a bed of golden flowers, when a body plummeted hard onto the ground. He couldn't even see what had happened at first, petals had scurried into the air, twirling and weaving in his vision. But, when they settled, Shuichi could clearly see that a girl was laying in the dirt, petals tangled in her pink clothing and blond hair, her eyes shut tight.

My flowers are dead. That's what Shuichi thinks at first, until his stalling mind catches up to the scene before him. He stands, frozen. He curls his fingers, but finds nothing but emptiness between them. He rips his gaze away from the petal-adorned girl to look down at his feet. His watering can is on the ground, lying on its side, water pooling around his shoe. He bends down to pick it up but, finds its completely empty. It would be impossible to water his flowers, now.

So he scuttles away, his hand clutching at the handle as he makes it to a nearby pond. Once there, he submerges the watering can to refill it, letting the cool water lap at his arms. Behind him, the frogs croak their familiar tunes and ones in front of him leap from lilypad to lilypad. With a few calming breaths, everything is back to normal.

Except, when he returns, there's still an unconscious girl in his garden. He hadn't imagined her. Nor did he dream her up. A girl is in his garden. A human girl.

The watering can slips from his fingers again and it hits the ground with a resounding clank. The girl stirs in her sleep.

Panic surges through Shuichi, he quickly flees to a safe distance but, he makes sure to still keep her in sight. "Um, excuse me?" he calls out.

Nothing. Her body remains still. He reaches out to her, wondering where the otherworldly creature had came from. He had never met a human before, it was impossible for them to come to the underground. And yet, one of them lay in his garden.

Then, her eyes open. She mumbles something incohesive and rolls her head to look around. "H-huh?" Her body shoots up fast. Too fast. She squeezes her eyes shut and slowly lies back down. "Where am I?" she groans out as her head makes contact with the ground.

Shuichi blinks. "Oh, um, this is the Ruins."

She turns to him, as if only now realizing he was there. Her violet eyes look directly into his own, stretching wide with awe. He lowers his cap. "The Ruins?" She echoes.

He nods.

She tries to sit up again and, with a pained effort, she manages to do it. "I-" the girl looks down at her body, "How did I...get here?"

Shuichi points up towards the endless cavern tunnel, stretched up for miles above them.

Her head tilts upwards. "All the way up there?" she breathes and then goes silent for a long time before, "I did fall, didn't I? Yeah, I remember that."

"You remember what? Falling?" he asks.

"Uh huh," she rests her head on her palm, "And that's all l remember."

"What do you mean?"

"I, uh, oh gosh, this is going to sound really crazy," she takes a moment before continuing, "My head feels...foggy? My memories don't really make sense. I was at home, then I was falling, and now I'm here. I can't recall what happened in between."

Shuichi's curiosity starts to trump his common sense and survival instincts, he inches closer to the human. "H-hey, that doesn't sound too crazy," he tries to comfort.

She snorts. "Come on, don't lie. I know it does."

"I'm not lying," he mumbles, getting even closer. Stepping on his own flowers to do so, until he's right beside her. "Maybe you hit your head too hard. You probably need some rest right now. I'm sure your memories will come back once you've recovered from the fall."

"Maybe," she replies, sounding as confident in that idea as Shuichi felt. Which was not at all.

Then she stands up and wobbles unsteadily on her feet. She dives to hook onto Shuichi's shoulder for balance. Their eyes meet for a second and he quickly turns away. She doesn't. In fact, she lets her eyes wander across his whole body. Then, she starts poking around his face. Not quite touching it, just prodding the air around him. He instantly regrets getting close to her.

"I-I guess you could come to my house. I have a plenty of spare rooms you could use," he offers, silently begging for her to stop.

"That be nice actually. Thank you," she says, sounding distracted. She stops the air poking but, continues staring at him, her eyes squinted. "Hey, um, this is probably another symptom from hitting my head, but you have, like, this blue glow around you."

Then it clicks in Shuichi's brain. Of course a human wouldn't recognize monster traits.

"Oh, you're not seeing things, it's actually there" he explains, "because I'm a ghost."

He can't tell if the blank expression on her face means that she doesn't believe him or doesn't know what a ghost is. Either way, he figures words won't get him very far. So, he takes a step back and bends one leg up. Then, the other. And, instead of crashing to the ground, he remains where he was. Floating slightly above the ground, feet tucked under him.

The human girl stares at the space between himself and the ground. She blinks, lets out a soft laugh, then faints.

By the time she wakes again, Shuichi had managed water the plants. It was difficult working around her and he hopes she doesn't notice the few stray droplets that had landed on her arms. He's still unsure of what does and doesn't upset the human, afterall.

When she regains consciousness, her eyes snap open and she pushes herself up into a sitting position. Her head whips around to face him.

"You're a monster, aren't you?"

Shuichi puts down his empty watering can and nods, "Yes I am, and sorry, I didn't mean to scare you." He rubs the back of his neck "Are you feeling better now?"

"I... am, a lot better actually," she says but her voice is strained. "I didn't mean to pass out. I guess I was still lightheaded from the fall." She shakes her head. "But, that's not the point. The point is you're a monster, right? So, how are you here?"

He shrugs. "I walked here, I guess?"

"No, that's not what I meant," she growls, "I meant, ugh, didn't monsters lock themselves behind a barrier a long, long time ago?"

"Um..yes?"

She's silent for a moment. "Where did you say this was again?

"The Ruins."

"The underground Ruins?"

"Um, yes."

The girl closes her eyes and lets out a nervous laugh. "So, you're telling me I'm in the underground realm. The one filled with monsters?"

Shuichi blinks in surprise. "You didn't know?"

"No" she snaps. "I told you, all I know is that I was at home and then I was here." He slinks back so she adds more softly "All my memories are missing."

He perks up. "So, wait, does that mean you don't remember how you got past the barrier?"

She shakes her head. "No, not a clue. I...I literally did the impossible and I can't even remember how it happened. Do you have any idea on how a human could have gotten down here?"

Her gaze bores into him, waiting for an answer, but Shuichi has none to give. "Ah, maybe you...or there could have been a… I, uh".

"It's okay. It's fine." She quickly interjects, "Worrying about it won't solve anything. Besides, my memory will come back eventually… right?

Shuichi looks away as he says, "Yeah, it has to come back at some point."

"Exactly. I just got to remain calm." She takes a heavy breath, and then stands up, wincing from the effort.

"It's weird, though," she continues, "I thought monsters would be more," she makes vague gestures with her hands, "monster-y. You look just like a human except for the uhh," more vague gestures.

"Oh, thanks?"

"I don't mean that in a bad way!" She adds, "I just mean you're not scary at all. I thought monsters would be more ferocious."

"Why?"

"I don't know," she glances down. "We don't really talk about monsters on the surface. I guess I assumed they'd be more dangerous."

Shuichi lets out a nervous chuckle. "We don't talk about humans down here, either."

The girl smiles. "Am I what you expected?"

He shakes his head. "Not really, but I didn't know what to expect from a human anyway."

"I know what you mean," she sighs, "Well, I'm glad monsters aren't what I thought they were. And, I'm especially glad the first monster I ever meet was someone kind like you. I'd probably be freaking out a lot more otherwise."

He adjusts his hat as he turns away. "I'm not doing anything special."

"Still, I'm happy you're here with me, um… Mr. Ghost?"

Shuichi looks back her and she fidgets. "That's probably not your name, huh? Sorry, I guess I should have asked a while ago."

"Ah, no, it's okay. I'm Shuichi Saihara," he introduces, "Is it okay if I ask for your name?"

"Of course it's fine, I'm Kaede. Kaede Akamatsu."

Kaede knew the underground would be different from the surface, but she didn't feel under the ground at all. The Ruins were a series of long corridors, surrounded by purple walls. Every once in awhile, the corridor opens up box-shaped rooms, each containing some sort of landmark: like ponds or lone trees. Beyond those rooms, are just more hallways. It felt like a funhouse maze that they have at carnivals, except with only one way to go. Shuichi had reassured her that the Ruins weren't artificial and everything she saw (expect for the buttons and switches on the walls and ground) happened naturally. The realm of monsters just worked like that, she supposes.

The other thing that struck her as strange is the frogs hopping around the place. She doesn't know why, but Kaede hadn't thought that there'd be animals alongside the monsters.

"Yeah, we have animals" Shuichi says when she asks. "The Ruins has all sorts of species of frogs, too. We have the green ones and the purple ones with wings and the red ones that generate heat. Just like you have on the surface."

Kaede's is too disturbed to respond.

They walk a little further. Shuichi sneakily tries switching from walking to flying, but it's not all that subtle and it was jarring having him float alongside her. His blue "aura" shined brighter when he flew, too. The glow would react to his movement, rolling like flickering flames around his body. Which, only made things feel weirder but, it was something Shuichi was clearly more comfortable with. On two feet, he was stiff and lagged behind her. In the air, he was more mobile, sailing through the air like a breeze.

"It's really cool that you can fly like that," she comments.

"Oh, no, it's not as cool as you think," he mumbles, floating over another stream while she walks across a bridge. "I can't go much higher than this. It's more of a hover than anything."

"You don't have to be humble about it," she says. "It's one of the craziest things I've ever seen."

"No, really, it's not that impressive. I think you're only saying that because you never seen anyone fly," he turns to her. "I'm guessing from your reaction that humans can't fly, can they?"

"Pfft, I wish," Kaede laughs. "Can all monsters fly?"

"No," he replies. "Ghosts can and I think some dragons can, too."

Kaede stops dead in her tracks. "D-dragons!?"

He stops as well. "Yeah, ones with wings can."

She frowns and starts moving again. "Oh." She says, silently praying that they never run into a winged dragon. Or any dragon for that matter. "So, do all monsters have different powers?"

He nods and flicks some lever that opens up a path. "All species have their own unique abilities."

She brightens up. "Is there a monster that can restore my memories?"

Shuichi thinks for a moment before saying, "Actually, I think the king of monsters might."

She perks up, excitement surges through her. She smiles at Shuichi. "Really?"

"Ah, but, I don't know for sure," he quickly adds. "And, it's not like you could ever go see him. So, so, I shouldn't have said anything in the first place. Sorry."

Kaede tries not to let her disappointment show as Shuichi tugs frantically at his hat. She decides against pushing the topic further. At least, for now.

They walk in silence for a little bit before they come across a wide, open area. The lavender path they had been walking on suddenly stops in front of a building. It's short, but stretches wide across the terrain. The white walls, window planes with cute flora-patterned drapes, and the mailbox standing right outside it makes it feel like it could be a normal home, but it stands out in the outlandish, purple environment.

"We're here," Shuichi cheers, "this is where I live." He walks through the front door and lands back down on his feet.

Kaede follows behind, entering a very spacious living room. A humongous couch is in the middle of it, right in front of a TV. Kaede questions how such a thing works underground before focusing her gaze on two shelves flanking the walls, each packed to the brim with neatly lined books.

"Sorry for the mess," Shuichi apologizes for the very orderly and organized room.

"Don't apologize, I'm the one intruding after all," she says before allowing herself to collapse face first onto the sofa.

Shuichi shuffles around her and picking up a few stray books on the coffee table and placing them on a shelf. "Are you going to sleep there?" He asks.

Kaede rolls over. "No, I just needed to relax for a second." Then adds, "I've had a long day."

"Ah, okay," he says and continues to organize the books.

She runs her hand through her hair and lets out a sigh. Kaede always had a knack for getting herself into strange situations, but this was definitely the worst it had ever been. Fear starts bubbling in her belly. She had no idea how much longer she'd be stuck down here. Or how many more monsters she would run into. And what about her family? Had her they noticed she was gone? She can't even remember when she left the house, her exhausted brain won't provide any answers.

"Hey, Shuichi?" she calls. "There's...a way to get back to the surface, right?"

He tenses before saying, "Yeah, there's a place near the castle where the barrier is crossable."

Kaede relaxes but her heavy eyelids ache. "Hey, Is there a bed somewhere I could sleep on?"

Shuichi nods. "Bedrooms are over here" He glides through the air, leading her away from the living room and into a hallway, doors lined up on both walls.

"That's my room" he points to a baby blue door. "You can choose one of the other ones to sleep in."

Kaede looks at the rows of doors, each on painted with their different colors. "Does someone else live here?"

"No" he says hurriedly. "Just me."

She hums and moves across the hallway, to a door with a dark-purplish finish. She lets her hand rest on the doorknob. "Hey, Shuichi?" He perks up, "Thanks again for this."

"Of course" he replies, "You really don't have to thank me, it was no trouble at all."

"Still, if it wasn't for your kindness, well, just think how scared I'd be right now." He doesn't say anything to that, so she continues. "Really, thanks, and good night, Shuichi."

"Uh" it's hard to see his expression under the rim of his hat, but she can see his knitted brow. "Okay, I'll see you later." He turns the handle (Kaede half-expected him the just phase through the door) and disappears into his room.

The bedroom she chosen is fully furnished yet, very plain. There's a bed tucked into a corner with nothing but solid white sheets and pillows. The nightstand beside it has nothing on it except for a collection of dust. After checking, she also finds that all the dressers and the closet are completely empty as well. It's not until she throws back the covers does she see the only item in the entire room. Lying on the mattress is a photo of a little girl and an older man standing in the garden she had fallen into. They're both smiling and holding hands, and Kaede doesn't miss the way their bodies give off colorful glows. Especially the little girl, whose own glow matches the color of the bedroom door.

She places the picture on the nightstand and falls asleep.

Kaede instinctively looks out the window when she wakes up, expecting to see the Ruins bathing in early morning sunlight. But, when she does, she realizes why Shuichi had acted so weird when she told him goodnight. The landscape wears the same shade of purple as it did before she fell asleep. It's disorienting. She has to wonder how monsters keep track of time without the sun.

Kaede hobbles out of bed, her body feels less sore than it did yesterday. She stretches out and walks a little around the room. No shooting pain, that's a big improvement she thinks. She had expected the damage to be greater, a few broken bones at least. The memories of her fall aren't that clear, but she knows she must have fallen a long ways. She guesses it didn't matter, since she seems to be fine now.

Shuichi is waiting for her in the living room, sprawled out on the floor and reading a book. When he notices her walking in, he smiles. "Do you feel any better?"

"Yeah, a lot better actually. Just a bit hungry, though."

His eyes widen. "Humans eat, too!?" he exclaims, then quickly lifts the book up to cover his face. "Ah, sorry, I didn't mean to say that out loud."

"It's okay. And, yes, we eat. It's one of my favorite 'human' activities" she jokes.

Shuichi chuckles in an awkward and forced way. "Okay, I'll whip up something for the two of us" he says and Kaede has to stop herself from expressing her shock about finding out that ghosts eat. "Do humans- I mean, do you like butterscotch pie?"

She thinks it's an odd breakfast choice but nods anyway. They walk over to a joint kitchen and dining room. The latter holds a large, round table, complete with a set of wooden chairs circling it. "Just take a seat and I'll get the food ready." Shuichi instructs and she doesn't reject the offer to do nothing and get free food in return. She chooses a seat directly across from the kitchen.

A pleasant silence hangs in the air. It's peaceful, watching Shuichi cook while she relaxes at the dining table. It's almost reminiscent of a normal morning in her own home, with her own family. All she needs is a piano to play and it really would be like any other morning of her life. But then, the happiness she feels starts to drain away as the empty chairs surrounding her give her an odd sense of isolation, even though Shuichi is only a few feet away.

"This place sure is big for just you" she comments, drumming her fingers on the table.

He doesn't look up from the stove. "Well, this house wasn't built for just me."

"Did someone else used to live here?" she asks.

"Yeah, uh" He bows his head a little. "A bunch of ghosts used to live here, actually."

"Oh, and they moved away?"

"Yeah, the Ruins aren't as populated nowadays" Shuichi explains. "A lot of monsters moved away to be somewhere with more monsters."

"I see, and you got this whole house to yourself, now. That must be nice."

Shuichi doesn't respond. When he's done cooking, he places a slice of pie in front of her and sits in a chair directly to her left. Kaede tries to be polite at first but, manners were no match against her ravinish hunger. She starts shoveling fistfuls of food into her mouth and, luckily, Shuichi is smart enough not to comment on it.

"I really appreciate all the help, Shuichi" she says once she downs her last gulp.

"It really was no trouble" he replies sheepishly.

"No, you did a lot for me when you didn't need to" she places a hand on his shoulder. "Really, thank you. I've completely recovered thanks to you. So, after this I'll finally get out of your hair and get going."

His head snaps around to look at her. "What? Where are you going?"

"The castle, obviously"

"You're leaving so soon?"

"Of course, the sooner I get to the surface the better."

"B-but you don't understand. The castle is on the other side of the underground. The journey there will be long. Very, very long."

Kaede feels her heart stop. "You're kidding" but Shuichi's sharp gaze tell her he's serious, "Then, that's only more reason to leave as soon as I can!"

"But, you need to recover more. The journey is going to difficult. Not to mention the monsters you run into...won't all be as friendly."

"Well, I can't stay here with you forever."

Shuichi flinches. "Right, of course, that's not what I'm saying. I just think you should be a little more prepared before you go. You at least need to defend yourself if you're going to travel the underground. Here-"

He staggers back to the kitchen and grabs something out of the cupboards. He returns, brandishing a knife with a shaky hand.

"What?" she gasps.

"To defend yourself."

He reaches out for her to take it but, she doesn't move. The sharp metal reflects back an image of her horrified expression. "Shuichi I can't-"

"I'm not saying you should attack everyone you run into, obviously, but…just something you should have. Just in case."

She looks back down at the weapon. Obviously, she wasn't okay with what Shuichi was insinuating she do with it, but he had a point. In the world of monsters, she was powerless. If ghosts could fly, who knows what other abilities were out there. Plus, she couldn't use Shuichi as a gauge to predict the level of hostility of any other monsters. She didn't know if there were monsters that would want to do her harm.

"Just in case" she echoes and picks up the knife.

He nods. "You should probably get some fighting practice in too before you go."

"I can't stall here that much, Shuichi"

"I know you want to leave as soon as possible, but hear me out. It's going to take a while for you to get back on the surface anyway. But, scrabbling around defenseless is only going to make the journey longer, if not impossible. If you stay and prepare yourself, than you actually save time in the long run" Shuichi rambles.

Kaede sighs. "I guess it would be nice to be confident that I can protect myself, but how am I even supposed to even practice that?"

"Don't worry, I know what we can do."

The lavender gravel crackles under her feet as she shuffles in place. Across the way, Shuichi is making sure the training dummy is tied securely to a wooden post. Well, a training dummy is what he called it, but to Kaede, it looks more like a doll with it's button eyes and yellow, yarn hair. It even wore clothes and someone had drawn eyebrows and a frown on its face, making it look angry. Probably because that was the only way to distinguish it from a child's plaything. That, and the fact that it was the size of her.

"So, you want me to fight the dummy?" she asks, flipping the knife's handle over.

Shuichi nods. "Yeah. I think it be a good way to practice fighting real monsters."

She looked into the dummy's button eyes. "So I just...stab it?"

"Yes, but not yet. I got to make sure everything is ready" He fastens the last of the knots, before stepping back to check everything over. A smile forms on his lips and he curls his arms around the dummy's torso, embracing it in a hug.

Shuichi quickly lets go. "Oh, sorry, f-force of habit" his cheeks grow a rosy color. "I do that sometimes be-because it seems to calm him down" he nods towards the dummy and backs away further. "A-anyway, you can attack it now. I'll be here in case things go sour."

She can't help but to stare at Shuichi - who is trying to make himself disappear under his hat - before turning back to the dummy, brushing it off as some sort of monster thing she didn't understand. She feels so dumb, pointing a knife at its slumped-over form. She didn't know how attacking it was going to help her defense skills. But, if this was a real fight, she won't be able to hesitant and, if anything, she wants this practice to count for something.

So, pretending it's a real enemy, Kaede charges at the dummy and it, in return, springs to life.

"Huh!?" Kaede stop, the knife jumps out of her grasp. The dummy struggles frantically against its restraints. It rolls, turns, and tries banging on the post. Then it's lifeless, button eyes move and look directly at her.

It doesn't make a sound, nor does its markered-in expression change, but Kaede can tell it is not pleased with her. A ball of white light appears at its chest, it grows bigger and bigger, until a small piece of that light breaks off- taking the shape of a diamond- and is flung towards her. It just barely misses. Kaede gasps.

"Kae-" Shuichi's call was cut off by the dummy hurling another attack at her. It doesn't miss this time, it hits her shoulder. She looks just in time to see the diamond projectile sear straight through her body.

Kaede screams, clutching her shoulder and falling to her knees. She waits for the pain, for the blood to come spilling out. But, nothing happens. She lifts her hand to find nothing. No cuts, no scratches, nor any wounds. She gingerly places two fingers where she was hit, pushing gently into her clothes. Everything felt normal.

"Don't worry, he's not trying to hurt you" Shuichi calls. "He's only after your soul. That's the only thing you have to make sure he doesn't hit."

"My...soul?" she echoes. It's then that she notices a red glow coming from below. Thinking it's blood, Kaede looks down and there, drifting in the middle of her chest, is a red heart that hovers in the air, less than a fingernail length away from her body.

Panic, disbelief, fear-those are things she should be feeling right now. But, some instinctually part of her let's her embrace the magical flying heart, letting her know that it belongs to her. The heart, her soul, ignites something within her. Something stronger and more confident than herself. The tension in her heart soothes.

The dummy attacks again and Kaede side-steps out of the way. "Nice dodge!" Shuichi cheers.

A powerful feeling rushes through her and she can tell it's coming from her soul. Suddenly, nothing else matters. Not the battle training, nor getting out of the underground, not even her own safety. All that matters is her own growing determination to protect her soul.

"This is why the training dummy is so good for practice" Shuichi calls again. "All tied up like that, it's attacks are poorly aimed and he can't fire them all that fast. You got the advantage Kaede, you can do this!"

Just as he says that, one of the ropes snap.
