The Royal Runt (Blackstar x Reader) [AU]

Chapter 22: Wish

[Blackstar's POV]

She knows Einean. She's fluent. It's pretty obvious with how she wrote those words in that page…

According to (y/n), she controlled electricity and lightning… Like the ones that spark around my hands when I use my speed.

…What the hell is this…?

"Blackstar, are you okay ?" (y/n) frowned, tapping my shoulder. "Did… Did you read that page ? What was written in it ?"

It's been about three hours since I found that out…

It can't be. We can't be related. I'm a prince. She's a knight. I can't take it out of my head---how did this happen ? I'm placed here on purpose ? I'm a pawn ? What the hell ?

"Blackstar, I swear, if you don't respond now, It's going to hurt."

But still, she knew Einean. Plus, if she was my sister, she should've got part of Kid's powers, too. And she didn't. All she had was lightning. One power…

It might mean she's a servant. Or she's the first child of another royalty… Or we are.

"ANSWER ME !"

I winced as I felt a harsh slap against my cheek. That pulled me out of my little trance.

"O-ow !"

"I've been trying to talk to you ever since you've seen that damn page ! What the hell is wrong with you ?!" (y/n)'s voice boomed in the room. I stared at her with wide eyes, holding my sore cheek, which now I can guess is red and swollen.

"You look like you were in a traumatizing experience. You were trembling. You were staring down at that damn diary for what, three hours now ?! You're not even telling me anything ! You're making me worry---do you want me to die from a heart attack here ?!"

She herself was trembling. Only thing was, in anger. Her hands were balled into fists, her knuckles white from clenching them.

And she had tears in her eyes.

"…(y/n)…" I looked down at my hand. And indeed, it was shaking… I frowned, but looked back up at her. She was starting to calm down. But her tears weren't.

"I… I'm sorry." I mumbled, sighing. She only stared, but soon she leaned close and pulled me into a tight hug… She was really warm.

…I'll think about Tsubaki later.

"I'm so sorry…" I mumbled again, deciding to hug her back this time. That was the last straw, I guess. She started sobbing on my shoulder. "Y-you scared me ! You suddenly went still---you were really silent for three hours ! I-I thought something bad already happened to you ! Don't ever do that again---I'm going to punch your groin if you do that again !"

I sighed, deciding to pat her back as she cried. I was fine. I always am… I didn't even realize I looked that worse.

"It's okay… I promise…" I mumbled, doing my best to try and calm her down. But with the way she was crying at the moment, I don't think she'd calm down soon.

"I-I'm here… Please… Tell me if something is bothering you… I-I want to help…" She mumbled, sniffling and trying to wipe her tears desperately.

I took a deep sigh, before adjusting, doing my best to put her in a comfortable position. "…It was a warning… In that note… She said almost no one would understand those words. That language. But I did… I'm… I'm fluent in that language---I was born like that for some reason…"

Her silence was a signal for me to continue.

"It said… That if someone could actually read it---me, for an instance… It meant that I've come. Like---like me coming here was planned. Her plan. She told me to never take you off my sight. That I have to stay next to you at all times. She also said she dropped hints of who might be your curse's creator… But if I was able to read that… Yami no Hoshi. It's why I asked you what it meant. You said it could work as my name… Dark star. Blackstar."

I pulled away, and decided to meet her eyes. They were staring back at mine, waiting in anticipation.

"…She called me her little brother."

She looked startled, but… Soon, she took the diary, and sat next to me. "…She knew your language… You both somehow had the same power---you with speed and sparking hands. Her, with electricity…" She muttered, starting to flip pages rapidly.

I watched, not even daring to move. Yeah, I'm still me. But… I'm starting to think everything in my life is a lie. So Kid's not my brother ? What about Dad ? Is it why he sent me here…?

…Am I really just a knight ?

"She said according to researches… The person had red hair. He was a start-up killer from some other kingdom… He even ended up killing the whole population. But the royal family got away. Tsubaki used that story for bedtime… That kingdom's name… Astra. The murdered people, who were nameless because they were mere townspeople… The queen felt really bad for them. So she whispered aster, and the people turned into bright lights. Shot up to the sky. It was why we can see constellations as of today. Those constellations were the families, together even death... All of that was in the story."

"…Where are they now ?"

"No one knew. The royal family disappeared. Even their personal knights seemed not to make it, too… That was long ago, that story."

"How long ago ?"

"I-I don't know…"

I made a slight sigh, nodding. "So… What was that kingdom's symbol ?"

"Roses."

I tensed. Roses. Again. I turned to (y/n)'s wrist, and saw her curse mark again… I think that's a rose. That reminds me. Fleitte's temple… He has the same symbol.

"…Is that symbol the same as the one on your wrist ?"

(y/n) paused, and looked down at her wrist. Then, she frowned. "…Yes. Tsubaki said so. Maybe she saw it in books, maybe someone told her… I don't know. But yes. That's what she told me… "

This is too much information. First, Tsubaki is possibly my sister. That would mean lots of things. And now, that Fleitte is possibly from Astra, that fallen kingdom. I guess he's an Astrean. Our people are called Einean, and (y/n)'s are Eian.

Oh hey, pretty cool.

"…I'm going to do more research." She suddenly said, standing up. "I don't want you to think about it too much…"

I reacted of course. An Einean writing from Tsubaki just told me not to get my eyes off of her. And that's what I'm doing.

"Hell no. I'm going with you."

"I said I don't want you to think about it."

"(y/n), it just said I have to be with you at all times---"

"That's an ORDER, Blackstar." She turned to me, with a menacing glare. I had no choice but to back down. I was still her knight, and I follow her orders… Even if I don't want to, I have to follow her commands.

"…Please be careful." At this point, I don't even trust the castle anymore. Anyone might be a threat to her. I had to be there to protect her…

She managed a small smile. "I'd be lying if I said I always am." She said, and I simply managed a chuckle as she left the room.

…I'm being overprotective, aren't I ? News flash, I don't give two shits if I am.

I have to admit, I've gotten attached to that klutz of a princess. How long has it been since I was he knight ? I lost count. But being in the palace, all on my own with no one other than maids to talk to… It seemed like some other life that felt forever ago.

This is unusual. I don't even want to go back to that life.

I don't want to wear that heavy ass crown again. I want to be a knight forever. Her knight.

……It's morning, but I hope one of the Asters heard that wish.
