Well, it seems I will temporarily focus on this story first, because it DOES have an impact on the OCs' backgrounds.
A little note for everyone: all BOLD details are basically spoilers to those who has followed me so far. For newcomers, keep those details in mind, because it will make sense in the future.
With that out, let's get to the main story!
"So… where are we going now?" Emerald asks Shidou, as they're joining the citizens that come out of the underground hiding bases.
"I need to return to the school first to get someone. Mind you, she's a Spirit." The boy answers, as he leads the girl to his school.
"By the way, how successful are you in this? How many have you saved?"
"Eh… Actually, I was just in this a few days ago."
"So she's your first then?" Emerald asks with a gleeful smile on her face.
"Yes, my first success mission." Shidou replies… then notices how the girl's smiling at him. "What?"
"Nothing, nothing at all." The girl turns to another way while hiding her smile under her hand.
"Okay…" Shidou says awkwardly, not understanding what Emerald is implying.
A few minutes later, they manage to reach a base near the school, as the students are pouring out of the safe location. Shidou then spots the one he needs to find: "Tohka! Over here!" The girl spots him and she rushes to him immediately. "Are you okay?"
"I should ask you that, Shidou!" Tohka asks worriedly. Then, she notices Emerald standing next to him, and she casts Shidou a look of disbelief: "Shidou, you left me just to meet with someone…"
"You are miss Tohka, right?" Emerald interrupts, as Tohka turns to look at her. "My name is Emerald Heart. Nice to meet you." She then points at her lips and mouths 'I'm a Spirit' under her breath.
"She was the cause of the spacequake, like you." Shidou whispers into Tohka's ears, earning a nod of understanding from the Spirit. "We should head back to my home now. Let's go."
Upon reaching Itsuka's residence, Shidou finds out that Kotori and Reine are already in the house waiting for his return. The girls take a seat for themselves in the living room, as Shidou starts preparing some tea for everyone. Kotori then asks Emerald: "I have to say, we're very surprised that you know about modern technology. May I ask what you are, if you're not a Spirit?"
"Not a Spirit? I thought you said that you're one?" Tohka asks the girl confusingly.
"Shidou is about to be scolded by you, so I have to move first. Although, my appearance did cause the spacequake, albeit not voluntarily."
"None of the Spirits' appearances are, miss Emerald." Reine says. "You seem to know about the Spirit, despite just being here for the first time…"
"I don't know." Emerald interrupts. "I was informed that there is a number of individuals that obtained power similar to me. How different, that's what I have to find out by myself."
"Obtained?" All the girls asks at once. And Reine quickly follows: "The Spirit's power is not their nature?"
"That, I do not know. The one who informed me is… a person who likes mysteries. He's not someone you can really get a straight answer unless he decides to do so."
"Sounds like some higher-ups here." Kotori comments. "Scratch that, that's all the higher-ups."
"I can relate. Thank you mister Shidou." The boy has done preparing the tea and some treats, as he brings it to the living room.
"You're welcome." After putting the tray down, Shidou takes a seat and joins the conversation. "May I ask this? If you're not a Spirit, then what are you?"
"…I can't say much about it. But, you could say that I'm somewhat similar to a Spirit in terms of power." That's the closest thing Emerald could say to not reveal herself much.
Tohka, after consuming a few candies, asks: "So you're going to join school too?"
Emerald giggles at Tohka's expression during her question, and she answers: "I have passed the age to study in a high school. Maybe I will find a job nearby, and rent somewhere…"
"How about joining our organization?" Kotori offers. "Right now, AST is registering you as a Spirit, so it could be a problem if you accidentally meet one of their members. With Ratatoskr's help, you could stay here with no problems."
Emerald nods. "Thank you very much for the offer. However, I don't believe I should stay with you here…"
"We could provide a new residence, in case more Spirits show up." Reine continues. "About jobs, you could help us with our cause."
"… Your objective is to save these Spirits…" Emerald remembers her conversation with Shidou about the organization's purpose. "Then, I'm in."
"Great." Kotori smiles. "Our job would be easier now. About…"
"However, I do have a request to ask." Emerald interrupts. "As you have heard, I'm looking for a person." She draws out a picture from… somewhere, before giving it to Reine. "The person who asked me for the help told me that she's both easy and hard to find."
"Then he's right." Reine replies. "She's a rare case like you, but, her appearances usually involved into some bad cases of brutal beatdowns or killings, but the latter were also rare, and the victims were usually criminals."
"…Just like him…" Emerald says quietly under her breath. Then she replies with a grateful smile: "Then, if you have anything on her, please tell me."
"We will." Kotori says, before pulling out a lollipop and she's about to put it in her mouth before Shidou snatches it out of her hand. "HEY!"
"You can eat the candies in the plate, but no lollipops." Shidou says, not surprised at her addict in lollipops.
As Kotori's sulking, Tohka then asks: "Hey, Emerald. Who is the person you kept talking about? Is he a friend of yours?"
"He is. Though, he's not someone we could call a 'normal' friend."
"Elaborate." Reine says, curious at how she said it.
"He's… extraordinary and paradoxical, as the best way to describe him." Emerald answers.
Kotori: "Like?"
"He can receive a bullet shot to the head without complaining, but he could immediately cry if he stumbles his toes into something." That earns her looks of stupidity from the others. "We can't really understand him either, even though he's around for so long."
"Like Tohka with the food then." Shidou says, earning a pout from the said girl.
Some kind of ringtone suddenly rings up in the air, causing everyone to look around to find the source, then focus on Emerald as she pulls out her phone. "He's calling…" She then puts the phone on the table, as a screen pops up in the air…
And everyone gasps in surprise. The call is made with the calling person… being under the bottom of some kind of water body, with chains binding over his body. His black short hair is floating up a bit, with his glasses slightly move up as well, and his black eyes are narrowing in annoyance towards the camera. Then, he asks, somehow his voice's not affected by the water: "Emerald, have you found her?"
Emerald sighs. "Yes and no. She's indeed here, but it will be difficult to exactly find her." She then changes the subject: "Did she turn into Yandere again?"
"Yangire, to be exact. After finding 'that' out, she just practically threw everything at us." Then, a mine slowly sinks down and lands right next to him, beeping dangerously. "…Who the hell provided her this?" Some more land down around him, then he looks up… and says: "Well, I will call you in the future. For now…" The call abruptly ends, and the screen disappears.
Emerald sighs then pockets her phone, and notices the looks of horror from everyone. She immediately assures them: "Don't worry, he will survive."
"HOW CAN YOU BE SO CALM?" Shidou shouts in shock. "Don't tell me it's normal in your place?"
"If those things are applied ON him, then yes." Emerald replies. "On the others, however… don't even THINK of doing so. He would be Death itself if you danger anyone other than him."
Everyone shivers when Emerald describes the person's character. Except Tohka. "So he's going to be okay?"
"Kinda. Not sure if he could survive her 'wrath'. Then again, Kuro has many ways to deal with things." Emerald doubts Kuro would die… again. But still… "Anyway, what time is it now?"
Nighttime
"How was your first day going, my dear sister?"
"Not much, Big Sis. The greeting was filled with machine guns, though."
"*Sigh* I know Kuro has warned me, but… I was so worried."
"*Giggle* I'm sure he would wipe everyone out if he knows they're dangerous to us."
"So… if Kuro said that you're not fit to be a student, then what can you do?"
"Apparently this organization is planning to save the Spirits by… make them 'fall in love' with a boy named Itsuka Shidou."
"That… certainly sounds like a dating game… Are you going to join in as well?"
"For fun, then yes. Don't tell it to her though. She would be very upset…"
"At you, or at him? *Giggle* I'm guessing you're saying about the latter."
"You can guess. I'm also tasked to help him saving those Spirits as well, since I told them that I'm as good as you are in these types of games."
"That's my Sis. Also, can you send me these games? I would like to give them a test."
"I will send you right away."
"Also… about whom Kuro's looking for…"
"It's going to be hard, but these guys will try their best…"
"Then he will appear, right? Typical."
"That's our Kuro."
A day later, after some searches around, Emerald managed to find a job in a bookstore near to Shidou's school. With that, she could easily get in touch with him and the Spirits, while keeping herself hidden.
"Strange? Why is it raining now?" The shopkeeper asks, confused at the sudden change of weather.
It is two days after Emerald got the job. And it's just near the end of her shift. She looks through the window of the store before checking the weather forecast app in her phone. "Strange indeed. The forecast said that it's going to be sunny all day."
"Anyway, I'm closing a little sooner. I need to get to the mall to meet my friends."
"Then I should leave as well. Goodbye."
With her umbrella out, Emerald starts walking back to Itsuka's home, or rather, the house next to it. Though, during the walk, she decides to take a short turn to a groceries store and buys a couple of food…
When she grabs one of the bento boxes, her eyes make a contact with Origami's. The AST soldier backs away immediately, remembering the face of the escape 'Spirit'. "You…"
Seeing her reactions, Emerald could guess that the girl knows her… in a bad way. "Um… Do I know you?"
Origami's gaze hardens. "The new Spirit… how did you get here?"
"… Ah, you're from the group that tried to shot me, right?" Emerald says in a low tone, so the customers nearby wouldn't hear it and freak out.
"… You are a Spirit. Your very existence dangers us."
"And I find it hard to believe." Emerald walks a bit closer to Origami and lowers her upper body down so their eyes are on the same level. "You attacked us on sight, and assumed that the destructions were caused by us. Yes, it might be true that our arrivals caused those spacequakes, but we never had any intentions in destroying the world."
"I find that hard to believe. Every time your kind showed up, it filled with dead people."
"Like I said, we didn't have the intentions. Our travels simply did so for some reasons."
"You…" The white-haired girl grits her teeth in anger. "Because of you… your kind… my parents…"
"So that's why." Now that's something she has heard a lot of time. She then stands up and re-grabs the box and puts it into her basket. "My apology for bringing that bad memories up."
"You should." Origami straights herself up. Even though she wants to kill the 'Spirit' right here and now, she doesn't have her equipment, and there are people around. "We all have our sight on you, Goddess."
Now that catches her attention. She turns away from the AST soldier while saying: "Goddess, huh? I wonder why you give me that title… but, I guess I'm a little appreciated for that." Leaving a surprised Origami behind, she goes to the counter and pays for the stuffs, before leaving the store and heading back to where she lives now.
"That's slick of you, miss Emerald." The voice of the Vice Commander can be heard from the earpiece on her left ear.
"That's just something I learnt from my Big Sis. Who's that girl?"
"A top-tier student, same could be said in her AST squad. Shidou's self-proclaimed girlfriend, but she didn't say it out loud."
"A huge crush for our boy? Do you know why she's in love with her?"
"Unfortunately, that's a no. Though, it's not something you really concerned, right?"
"Correct. If you can, please give me some details about her past."
"It will be in your computer when you return. Have a good day."
"The same to you." She then looks up to the raining sky while saying to herself: "… Even though the rain's unexpected, it does bring out the right atmosphere. Well, let's return before Kotori has some reasons to pull me into her house."
Chapter 2 end!
Yeah, super-predictable. Kuro's also involved here. And I think you guys can guess who Emerald is now.
The next one will be Hermit's act. See you in the next chapters!
