After getting out of the hot spring, we moved to Isis-san's room. All that was left was to turn in for the night. Whenever I visited her castle, I usually spent my time in places like the archives, so I didn't actually have many opportunities to see her private chambers.
Lost in thought, I glanced back at her and felt the words die in my throat.
"..."
"...Kaito? Is something wrong?"
"N-No, it's not that anything's wrong, but... what on earth are you wearing?!"
I couldn't help but shout. Just moments ago, Isis-san had been in her usual gothic-style dress, but she had somehow changed into a see-through negligee while my back was turned.
Since she used magic to create her clothes, she could swap outfits in an instant, but that wasn't the point. The problem was the outfit itself.
She was wearing a light blue, see-through negligee. It left so little to the imagination that it was borderline scandalous. I was so caught off guard that I instinctively looked away, heart racing.
What made it even more of an issue was that Isis-san had never worn anything like this during my previous stays. Even the first time we had slept in the same bed, she had worn a babydoll, but it definitely hadn't been transparent. Why the sudden change tonight?
Whether a babydoll or a negligee was more provocative was a matter of taste, but the sheer visual impact of a see-through fabric was undeniable.
"...This? I thought... Kaito might like it. Do you... hate it?"
"N-No, it's not that I hate it, but... why the sudden change of heart?"
"...Um... Shaltier said before..."
For a split second, I wondered if Alice had been filling her head with more nonsense. However, I couldn't jump to conclusions without hearing the whole story. Besides, I doubted the bashful Alice would ever actually suggest something like this herself, even if she wasn't the one wearing it.
I decided to listen to the rest of what Isis-san had to say.
"...When she visited... she brought a magazine... and asked for my advice."
"She asked for your advice? Alice did?"
"...Yes. She said things like... 'Maybe it's better to start with an outfit like this, after all.' She consulted me... because she thought... I wouldn't laugh at her."
"I see..."
"...And so... I used the clothes in the magazine as a reference. Shaltier was... muttering to herself... that Kaito might like this sort of thing..."
"...Right. I get it now."
I could see how it happened. Alice probably wasn't trying to corrupt her; she’d likely been considering wearing it herself and wanted a second opinion.
Alice was the type who liked to look the part, and since she was a bit of a precocious girl whose head was filled with more theory than experience, it made perfect sense.
However, knowing Alice, she probably got cold feet and rejected the idea in the end. Meanwhile, Isis-san had taken the magazine she’d seen and used it as a reference for her own outfit.
...How was I supposed to handle this? Fundamentally speaking, Isis-san was breathtakingly attractive in that negligee. If I let my guard down for even a second, I’d find myself staring despite my best efforts to look away.
Isis-san and I were lovers, so there shouldn't have been anything wrong with seeing her like this. It was just that she was so pure that I felt a profound sense of guilt.
"...Kaito."
"Eh? —Wait!"
As I was agonizing over my internal conflict, Isis-san glided toward me and pulled me into a hug. The fabric was so much thinner than her usual dress that I could feel her warmth directly against me. My heart began to hammer in my chest.
Despite my obvious bewilderment, Isis-san smoothly cupped my face with her hands and pressed her lips to mine.
"...Mmh... Kaito... I love you."
The sensation of her soft lips and the whisper of her sweet voice were an irresistible combination. Reflexively, I pulled her closer.
Isis-san smiled with a gentleness that was almost blinding, her expression carrying a surprising air of maturity.
"...I'm... not quite as innocent as you might think, Kaito. So... all right?"
She whispered the words in a voice so sweet it felt like it was melting, then closed her eyes expectantly. Even I wasn't dense enough to miss what she was asking for. As I pressed my lips against hers again, I pulled her delicate body even tighter into my arms.
Serious-senpai: ".................."
???: "She’s flatlined. But more importantly, I—Alice-chan is taking a massive stray bullet here! I just got totally exposed! Oh, for the love of—! Anyway, the epilogue for Isis-san’s extra story is up next."
