I could still access my magical space on Earth.

The sun was still bright out there, despite the night out.

Since I was a NEET, I slept easier when the sun was up.

"Is this the other world, sonny? It seemed too small and empty."

My mother's wearing her casual getup. It fits enough with the other world's setting. I thought she tried to go in a school uniform and call me Onii-chan.

My mind's too much in the gutter since I wanted to sleep.

Mom's pretty excited at the fresh veggies on the farm.

"It's my magic space."

"Let's see...I guess it'd be convenient to stay here. I could make your meals as well."

"Hehe..."

"...but no, you're an adult. You'll find a good wife soon."

"Me?"

I couldn't even start to imagine that.

"Don't worry about it. Since you're Dad's child, the girls will go lesbian for you."

[Pfft...]

"It doesn't make me happy at all."

[Said someone who has so much yuri on his phone, or was it 'her' phone?]

Ugh...

==

System Imouto, can I teleport inside my magic space?

[Sure, it seems stable enough.]

Can you also store my excess mana?

[Weird you didn't bring it up sooner.]

I forgot, haha.

[Maybe if I call you Onee-chan enough times, you would remember.]

I don't think...it makes me happy.

[How cute.]

From now on, I want all my excess mana to go into my Inventory—I shouldn't waste even a drop.

[Got it.]

==

I waved at Mom.

"We're here."

She's still walking around the space; not entering the house at all.

"I don't feel anything different."

That was before we exited the space and went back to my Inn room.

Through the slightly-open window, I felt a surge of mana in the air, along with several moons and clear, dark skies. I gazed at the medieval-styled building, illuminated by magic tools.

Down below were people of unique races wearing armor, cloth, and robes. They had features that couldn't be found on Earth. Though it's already late out, only a few people strolled at this hour—mostly drunks.

"It was still dark out, so you can sleep at my space."

"The night's where it's at, my boy—or do you prefer daughter?"

"Well...anything is fine."

I don't think I especially want to be a girl.

I guess...it's pretty fun to roleplay as one, but...I don't think I want to wear cute clothes in the open.

I would really hate when dirty and hateful men eyed me. I prefer it if it's just for pure and kind girls who accepted me.

[Ohhh...so sweet, you're pretty much a maiden inside.]

...and you're like a dirty old man.

[I don't think pure girls would like you though.]

I know, right.

"So yeah, I'd be taking a stroll. How long are you staying?"

Mom happened to butt in, while I was drowning in dirty thoughts.

"Ahh...well, I don't know, maybe several days?"

"Got it." she went straight to the window, "Give my regards to the girl you always talk to."

"Ah." me and System Imouto respond at the same time.

With her gone, my desire to sleep escalate.

So I went back to my space, to my comfy spring bed.

When I woke up and went downstairs, I expected an uproar.

...but why?

It was so quiet.

Since I hadn't taken any of their meals for the past two days, I went for an extra. My tray was filled with boiled fries, hard bread, salad, corn soup, milk, and beer.

[MC-chan.]

What? Did my Mom kill some god or anything?

[No, she's currently sleeping in Jail.

She was caught peeking girls at the Bath House, and she complained their boobs were much smaller than your Dad.

...wait, what?]

Yeah, actually...his boobs were really big. I wanted to use a girl pronoun, but Dad felt much happier if you use the male one.

[Was it silicone though?]

I don't know.

It's just, we grew up healthy by drinking Dad's breast milk, instead of Mom.

Hello, System?

Oh well, I'd just finish this meal.

Adding salt really made things better!

[Anyway, I wouldn't be surprised if your little sister has a big penis.]

For that one...I'm not sure, I never saw her naked nor asked her.

[You should have asked her sooner! I think I couldn't sleep without knowing the truth.]

Wouldn't it be extremely rude to ask a girl about her penis?

[Why do you have common sense at this point?]

Alright.

Let's go visit Mom and ask her.

[Ah...this is so unreal. Visiting your Mom in jail just to ask whether your little sister has a penis.]

It's your fault for bringing it up, hehe.

If not one, it might be two.
