The Fifth Delusion
Whooooosh
"Ah, damn. It's freezing out here."
Our parents have been married for over twenty years now, yet their relationship is still as strong as ever. They go on trips together all the time. Right now, they're off in Europe. Said they suddenly felt like going.
Which means the only person home right now is my older sister.
It's boring being stuck at home with just her. So this morning I went out and played some futsal with my friends.
Since it's vacation and all, I figured I should enjoy myself as much as possible before I have to enlist. Waking up early and working up a good sweat feels great!
After finishing up, I came home. Wonder if Sis is still asleep?
She's kind, has a great personality, and is all-around wonderful, but she sure loves her morning sleep. I wish she'd get up earlier sometimes.
On top of that, she walks around the house in nothing but her underwear. Even if no one else is around, that's a bit much.
"Sis~ I'm home! Huh? Oh, hello? Um, who are you……?"
"Ah……, well, you see, it's like this, Gyeoul……."
When I opened the front door, I saw my sister standing there awkwardly. And right beside her…… was a male god who had descended into reality.
_____________
"So that's how it is. Basically, this person is another version of me!"
"Huh……, so you're saying this person is another side of you, Sis?"
"That's right. Hard to believe, I know."
I more or less understood what she was saying. So the male god standing in front of me right now is supposedly my sister from another world?
My sister usually dresses in weird styles, but she's actually really handsome. Even so, how could her parallel-world counterpart be this beautiful?
She's prettier than any guy I've ever seen. With looks like that, even famous overseas celebrities wouldn't stand a chance. If she walked around the city, she'd probably get numbers left and right.
How can a human even look like that? And me…… I kind of want to hit on her.
"Um……, I don't think Sis would do something like this, but isn't there some kind of misunderstanding? If she's another version of you, there's no way she'd be this pretty, right?"
"Oh! Thanks for calling me pretty, little sister. You're pretty too. I can't believe my little sister grew up into such a beautiful girl!"
Wow! She called me pretty too! I'm not sure if it's okay for a woman to say that to another woman (it feels kinda lesbian), but does this male-god oppa maybe have feelings for me?
"Hey, back off a bit. I'm trying to explain here. So even though she looks like this, she's another me who shares a lot with me. She knows all my secret preferences, you know?"
Ah…… Please don't back off. Keep talking to me.
No, wait.
Hold on. Another sister from a different world? Does that even make sense? Isn't Sis being scammed or something?
Oh, maybe not? My sister might be a bit naive sometimes, but she's sharp when it comes to things like this. There's no way she'd fall for something weird. And would someone that beautiful even need to scam people?
Besides, my sister's been that pretty for twenty-three years and has never dated anyone. She has zero interest in men, so no matter how handsome a guy is or how many lies he tells, she wouldn't fall for it.
Then……
If everything my sister said so far is true……
If this guy really is another world's version of her…… then to me, he's like an older brother?
I always wanted an older brother.
That would make him my husband given to me by our parents…… my one and only partner who shares the same genes as me……
"Really……? Still, I can't believe it yet. I'm going to keep watching. I don't think someone this beautiful would pull some weird scam, but it's still a hard story to swallow. So, this male version of you, Sis? What's your name?"
"I'm Kim Ga-eul."
"Your name's the same as Sis's too. But I still don't believe it! I'll be watching!"
So his name is Ga-eul oppa.
Ah. This isn't good. Why does this oppa smell so good too? I don't think I can keep my sanity much longer.
I need to get to my room fast. Gotta take care of this. My panties are already soaked anyway.
Click
I rush into my room and lock the door.
But my sister isn't interested in guys anyway. And if this is another world's version of her, she wouldn't like herself, right?
So…… does that mean oppa is mine?

_____________
Gyeoul closed the door and went into her room.
"Come on~, don't worry about it. It's such an unbelievable story that anyone would have trouble accepting it at first. She'll come around eventually. You know how kind Gyeoul is."
"Don't worry. I'm not concerned about that. I'm her brother too, after all. Well, in this world it'd be oppa. Anyway."
That part doesn't worry me at all. In the original world, Gyeoul was different from me—she had lots of friends, was popular with girls, tall, did well in school, basically had everything—but she never looked down on me.
If anything, even though I didn't have many friends, she'd sometimes play games with me or do card games together. She played with me. Huh? Wait a second. Does that mean all my friends turned into girls too?
Damn. Seeing that in person might be pretty shocking.
"Anyway! I believe you're another me from a different world. But there are still things I'm curious about, so let's check them together."
"Huh? Oh, really? Sure, let's do that. What are you curious about?"
"First, let's play a game together."
"A game?"
"Yeah. If you're really another me, wouldn't you play games in the same style as me? So let's try playing together."
The female me pointed at the game console nearby.
Oh. Right. If she really is me, her playstyle and preferences should be similar too.
"Alright. Let's give it a shot."
Playing card games with a girl was something I'd always wanted to do…… and now I get to do it with such a beautiful girl, just the two of us in a room!
"Actually, playing this card game with a guy was my wish."
"Huh? You too?"
"You too? As expected of 'me'!"
"Let's see what characters you used to play first."
"What was your main character?"
"I had several, but my favorite was Dragonkin Scarlet."
"Of course!! That's my favorite character too!"
Another me likes the same character. Makes sense—it's hard to resist a dragon who's also a maid.
Dragonkin Scarlet is a card theme that targets men with maid fetishes. Normally she's a diligent maid dragonkin woman who's loyal to the protagonist.
But when something happens, she transforms into her true dragon form……
Huh……?
Wait…… a second.
This is a gender-reversed world……
So in this world, maids are men? That means Dragonkin Scarlet would be a guy in a maid outfit?
Ugh. That's disgusting.
Even if it's just a game character, I can't bring myself to face that. Still, I have to live in this gender-reversed world now. To do that, I need to get over it.
Time to boot up the game!
Huh?
It's not a maid…… It is a dragonkin. And it is a guy.
But instead of a maid, it's a butler?
"It's a butler, not a maid……"
"Of course it's a butler, not a maid. Ah, so in your world Dragonkin Scarlet is a dragonkin maid instead of a dragonkin butler? Because the genders are reversed?"
In this world, women are maids and men are butlers, just like usual. Only their roles swapped while the names and outfits stayed the same?
"No, I thought I was going to see something horrifying, but I'm not sure if I should be relieved or what……"
"Ah! I see! You were confused between butlers and maids! Hehehehe. So you have a thing for butlers—or rather, maids—too! Why, should I play the maid role for you later?"
"No thanks, that's fine. Whew. Whatever. Let's just play the game already!"
While enjoying this game, I used to have a certain delusion. What if the characters in this game appeared in reality? What if they became summons that followed my orders and went on adventures with me?
I used to think things like that.
But coming to this world, all those pretty characters turned into guys.
Ugh
Male butlers instead of pretty female maids.
I hope this delusion never becomes reality.
Well, it probably won't anyway.

Japan, Rooftop of a High-Rise Building
Vwoooooom
A dimensional gate appeared in the air, and a red-haired dragonkin in a maid outfit emerged.

"Where…… is this?"
I definitely followed Master, but did I end up in a different dimension? The clothing of the people living here and the architectural style are very different from the world I adventured in with Master.
!
"I can feel it. Master's presence. Please wait just a little longer, Master. Your maid is coming right now."
Flutter
Giant wings appeared from the dragonkin's back.
Whoosh
A streak of red light shot high into the sky between the skyscrapers.
