The Assassin Girl Who Stayed by My Side in Another World… Somehow Followed Me Back to Modern Japan - Chapter 03: As Long As We’re Together

Chapter 03: As Long As We’re Together

“…Aira.”

“Yes?”

“…Can you leave the room for a second?”

I’d come back to my room to change into my school uniform.

That part was fine.

The problem?

Aira had followed me.

“Why?”

“Why, you ask—”

I stopped mid-sentence.

Right.

Back in that other world, she never really cared, so I ended up changing in front of her plenty of times.

She never made a big deal out of it.

…Maybe it’s because I’m physically sixteen again, but suddenly I wasn’t seeing her as a “daughter” anymore—

Wait, no. No, no, no. That’s not it.

That can’t be it.

Aira is my daughter. That’s all she is. Nothing more, nothing less.

I’ve been raising her since she was eight, for crying out loud.

There’s no way I’d ever see her that way—as a girl.

“…Never mind. Do whatever you want.”

“Okay. I’ll do whatever I want.”

And just like that, I did my best to tune her out and got changed.

“…I’m heading to school now. What about you, Aira?”

I already knew the answer.

Still, I asked—partly just to cover up the awkward tension.

“I’ll go with Hiroto.”

“…Right. That’s fine, I guess. But do me a favor—try not to let anyone see you, alright?”

Aira was from another world, so of course she didn’t have anything like a family registry here.

No relatives either. …Well, okay, technically I was her parent, sure.

But we’re not blood-related, and I’m still just a high school student—no one would ever believe me if I said that out loud.

Anyway, since she had no official documents and no family here, there was no way she could attend the same school as me.

And as much as I hated to admit it, I really couldn’t let anyone see her.

If someone spotted her on school grounds, she’d 100% come off as some suspicious stranger just hanging around campus.

…Okay, technically there might be a way.

Like, if I explained everything to Nee-san, maybe she could pull some strings and get Aira into my school too.

But seriously—how am I even supposed to explain any of this?

There’s no way she’d buy something like “Hey, this girl’s from another world!”

And even if she somehow did believe me, there’s no guarantee she’d actually accept Aira.

Sure, Nee-san’s super kind…

But when it comes to people outside the family, she can be pretty cautious.

Even if it’s a sixteen-year-old girl.

“I’ll do what I always do. I’ll be fine.”

…Yeah. That’s true.

Even in the other world, Aira was usually invisible when we weren’t alone together.

Always nearby. Always watching over me.

…Well, I assume she was.

I never actually saw her, so I guess I can’t say for sure.

But still… I’m pretty sure she was there.

“So, yeah. …Let’s get going. Time for school.”

It’d been eight years since I last stepped inside a classroom.

…Honestly, I had zero confidence I’d be able to keep up with the lessons.

Still, despite the nerves, the thought of seeing my friends again genuinely had me excited.

I grabbed the bento Nee-san had packed, locked the front door properly, and headed out.

I couldn’t sense her presence at all—but I was pretty sure Aira was following me.

“Aira, don’t show yourself, but answer me… You hungry or anything?”

If she’d come to this world at the same time I did, then yeah—she had to be getting hungry by now.

The thought hit me out of nowhere, so I asked.

“…I am.”

“…Wanna stop by a convenience store?”

We could always split my bento at lunch.

If I wasn’t a broke high schooler, I’d have bought her her own without even thinking about it.

But sadly, I didn’t have a part-time job or anything yet, so my wallet couldn’t exactly handle feeding two people.

“…Probably, thanks.”

That “probably” was because she had no idea what a convenience store even was.

I’d given her a general rundown of how things worked in this world…

But convenience stores hadn’t exactly come up.

“Don’t worry about it.”

Buying breakfast for Aira definitely left a dent in my wallet—but it’s fine.

She’s my daughter, after all.
