Main Story Side Story: To the One and Only Star (3) [Theme Park Cosplay]

Passing through the dark entrance and entering the theme park’s main hall, even though I was a grown adult, I felt like I had returned to my childhood for the first time in a long while.

Rides moving with colorful lights, part-timers wearing mascot character costumes and taking photos with children, excited children holding ice cream and churros in both hands, and even their parents.

A fantasy land everyone would want to visit. This is a theme park… a beautiful attraction, day and night, where people of all ages could make fun memories and return home… it was.

Until Mars suddenly turned his steps towards the costume shop.

“….Your taste is really bad.”

“Why? You said you’d swipe my card hard. Can’t you even wear this much?”

“Isn’t that different from this?!”

From the start, working for the Seven Stars and even having merchandise come out, telling Mars to pay for everything was a playful remark; I had no intention of actually doing that.

Although I usually live frugally, my mindset was to spend freely when playing with Mars, and today, I had resolved to agree to anything Mars wanted.

But… this was unexpected.

“Hmph… When did you say it suited me so well…?”

How hard was it to choose from the outfits Ciel had coordinated! I liked them all, so I agonized over it a lot.

Where did the sweet Mars I saw for a moment go! Why did he become a good-for-nothing young master again!

The Bunny Girl Leotard would be less embarrassing. No, it might even be better.

Of course, neither the clothes in Mars’s hand nor the Bunny Girl Leotard are outfits to wear around here. At least some glimpses of the former were seen, but… I still don’t want to wear it!

“I want to see your various sides. And I’ll wear it too, you know?”

“Even so..! I, I don’t want to! I’d rather wear my cosplay costume over there…”

No way.

It’s not a matter of exposure like a mini-skirt. Rather, if it’s wholesome, it’s very wholesome, but…!

“At this age, a school uniform… is a bit much…”

Even though I’m in my early to mid-twenties, wearing a school uniform wasn’t easy. The psychological repulsion was immense…

However, there’s no tree that won’t fall after ten axe swings. As I continued to refuse to wear the clothes, Mars finally decided to use his last resort.

“….Is that so. Can’t be helped then.”

“Huh? Uh… are you just leaving?”

“If you don’t like it, will you like it if I push you more? It’ll just make you feel worse…. Let’s go choose what to ride. If we don’t go quickly, the line will be full, you know?”

“…If you wear it… I think you’d be really cute.”

“…..Ha… He’s really bad at acting…”

Since force didn’t work, is he trying to ask nicely this time?

It’s a look I’ve never seen from Mars before, but… it’s obvious he’s lying.

I’m Phantom Thief Lupin. Do you think I, who disguised myself and infiltrated to act against nobles, can’t read someone’s expression?

I’ll never fall for it. Do you think I’d wear it just because he makes a teary puppy face? Not a chance… How dare he try to trick me.

Easy, easy~ Who would fall for fake aegyo? Especially sweet talk from a good-for-nothing young master who’s serious about fucking me…

Sweet talk… like that…

………

…….

…..

“Oh, you’ll wear it?”

“…….I don’t know.”

Ah.

No. No, Lee Seri!!

Why, why are my hands moving on their own? I haven’t been brainwashed, have I?!

I snatched the hanger from Mars’s happy hand as if taking it away, and went straight into the fitting room, giving a smile towards the mirror that I wasn’t sure was a smile.

The disappointed expression that made me give in might have been fake, but Mars’s smile of joy when I finally took the school uniform in my hand… was it genuine?

“Haa… I’ll never wear this again…”

Lee Seri, you crazy bitch… Who falls for it when they know better…?

I sighed and blamed myself, but what could I do about what had already happened? If I went out of the fitting room as I was now, I would truly see Mars’s genuinely disappointed face.

So, this is it for now. I’d rather wear a cow micro bikini than wear this twice.

Hmm… or not? Maybe the school uniform is better…?

I wouldn’t willingly wear something like that unless I was out of my mind. Giving Mars a lap pillow and a handjob right then wouldn’t be bad either, but…

“Are all girls’ school uniforms like this…?”

The school uniform I reluctantly put on, though it looked like a school uniform on the outside, felt quite different from the school uniforms in my memory.

For cosplay, it was made of surprisingly high-quality material, so the fit wasn’t bad, but it strangely accentuated my figure, how should I put it? Even though the vest and the skirt with a tail hole were somewhat okay, the white shirt was the problem.

There was no room in the arms, as expected, and it clung almost perfectly to my torso, undeniably revealing my body line.

There wasn’t a big problem moving, but my chest also felt strangely tight… The buttons aren’t going to pop, are they? Should I just adjust my body size and go out?

『Would you like to activate Body Adjustment?』

After transforming into a Succubus with an extra skill, unlike other Succubi who could transform into males, Nana Miwol didn’t have such an ability, but the range for changing her body shape was very wide.

In terms of age, she could de-evolve or grow by about a ten-year range, and although she hadn’t tried de-evolving, when she grew, her breasts got bigger, and she was incredibly surprised. She never thought they’d get as big as Hyun-ah’s…

The problem was that only the range was wide. Because she wasn’t yet skilled with the ability, once activated, she couldn’t return until the time limit ended, and she couldn’t make fine adjustments, so transforming into her desired body shape was impossible.

Naturally, reducing only her breasts was something she couldn’t even dream of doing right now, and if she were to walk arm-in-arm with Mars while looking younger than she was now, it would be a truly dizzying situation. In that case, he would truly be called a good-for-nothing in a dangerous sense.

Can’t be helped… Even if it’s a bit uncomfortable, I’ll just have to endure it. Since I’m wearing a vest, it should be fine even if one or two buttons pop.

The clothes… Ah, do I leave them here? Just in case, I’ll keep my Transformation Bracelet on.

“….Oh, wow~ Didn’t I tell you? That it would suit you well.”

“You deliberately gave me something that fits perfectly, didn’t you? It feels strange…”

As I came out of the fitting room, Mars, who had already changed into his school uniform, turned his head towards me.

Wow… He’s quite the shoulder thug, isn’t he…? Is he really the same person… no, is he a Clausin? At this rate, he wouldn’t lose to Mera’s husband, would he…?

He was originally well-built, but after several months of intertwining bodies with me and taking in a lot of my magical power, Mars’s body became flawless.

Especially his waist. Even if I poked it, it wouldn’t yield softly, but rather, his abs seemed to bounce back……

……….

…….

…

“….Is it fascinating?”

“……”

“Seri. Lee Seri~. Hey.”

“……H-huh?! W-what’s wrong?”

“She’s talking nonsense… What’s ‘yayo’? Is it half-honorific?”

I must be crazy… What am I doing in a public place…?

Not content with just poking his abs, I even grabbed his waist with both hands and kneaded it… It’s a nuisance, a complete nuisance, in a place with children!

Th-this is all because I became a Succubus! It might be that I lose my reason only when I see Mars. There’s no woman who wouldn’t be swayed with such a strong man next to her, you know?!

“S-sorry… I didn’t mean to…”

“Puhaha, surely you’re not turned on because you’re wearing this? You’re really something~.”

“W-who said that? It’s absolutely not true!”

Not knowing what to do with the hands that had grabbed Mars’s waist, I merely interlocked my fingers and took a step back, but Mars kept spewing nonsense and cackling.

Feeling the gazes of those around me focus on me, my face flushed, and I threw a punch at Mars, but my punch, without having transformed, seemed laughable to him, and he easily dodged all of them.

“Phew… I had a good laugh… I’ve paid for everything, so let’s go out. Even if we start playing now, we won’t have enough time.”

“You, youuu….”

And so, we, having changed into school uniforms, went outside and rode various rides.

I didn’t know it inside the store, but after walking around outside, it seemed common for couples to wear matching school uniforms, as we saw them quite frequently besides ourselves.

…..Couples, huh… Mars and I aren’t like that, but my heart is pounding.

What if… Mars’s smile I see now…

is the same as the feelings I read…. then I….

“I didn’t know it would spin three times… It was quite fun.”

“Seri, you’re surprisingly good at riding, aren’t you? You were really excited.”

“Hmph~ This much is nothing~ The bullet hell shot by Magical Girls is faster. Speaking of which, Mars, you were quite good at riding too, weren’t you?”

Gyro drop, roller coaster, viking ride… We only rode things that were fast and scary, but except for my school uniform getting disheveled by the wind, I didn’t feel much fear.

Ah, but I’ve never flown in the sky, so maybe I was a little scared…

“If you’re scared of something like this, are you even a man? You’re worse than that boob-monster and 『Dwaeji』.”

Acting tough, huh… Honestly, both you and I are shaking our legs like crazy right now, you know?

I just want to sit down and rest a bit… It’s almost lunchtime, so I’m hungry too… But Mars probably wants to play more─

“..Seri, sit down and rest a bit. I’ll go buy some food.”

“Hey, I’ll buy it. The school uniform was quite expensive, so I have some conscience…”

“It’s fine, just stay here~ If I take you around, people might recognize you again and bother you.”

“Bothering, huh… They’re all people who like me, you know? Alright, I’ll stay here. Then… I want churros!”

“Ha, alright… I’ll buy one as long as mine, so eat it all without leaving any, okay?”

Wow… what an admirable choice of words.

Mars, who pressed down on my shoulder and forcibly seated me on the bench, headed towards the food truck booth.

Indeed… Even this morning, a photo zone opened because a staff member recognized me… Should I wear a hat or glasses now?

Even though I was wearing a school uniform, my face wasn’t covered, so some people recognized me while I was waiting in line for rides.

Fortunately, it ended with brief encounters like shaking hands or taking photos together, but there’s no telling when something like this morning might happen again.

“Haa…

Mars is also a noble, and the young master of a well-known security company, in other words, a large corporation, so he might wish for no unnecessary scandals to break out…

I can’t put a burden on him. I immediately manipulated the Nanomachines from my bracelet to create and wear a cap and glasses, but…

“Did you come alone?”

“The school uniform suits you really well! Oh? Looking closely, you’re a Succubus, aren’t you?”

“You’re really cute~. Hey, want to hang out with us? We happen to have one spot open for a girl~. You’d be perfect if you came.”

“…Ah.”

Fortunately, they didn’t recognize me, but… I could instinctively tell.

The men who grabbed my hand, which was manipulating the Nanomachines, were annoying and much more troublesome guys than my grateful fans.
