"Student Narise, you just mentioned your mother. Isn't your family all mermaids?"

When Miro Narase dried the water from the swimming pool, Yagi Miyuki still couldn't suppress the desire for knowledge in his heart and couldn't help but ask.

"No."

Miro Narase shook her head and smiled heartlessly, "I was picked up by my mother. I have grown up so old that I have never seen a mermaid other than me."

"Yeah……"

Yagi Mitsuyu nodded thoughtfully.

Then it seems that Mira Narase is just an ordinary girl who can turn her legs into fish tails. In addition to her body, she is a normal human being from her mind to her three views.

but……

Yagi Miyuki looked incomprehensible.

Even if the facts were already in front of him, he still didn't want to believe that a creature like a mermaid really existed. The mermaid that can turn a fish tail into a leg at any time is completely impossible to explain with science, okay?

never mind.

Yagi Miyuki shook his head and stopped thinking about these indifferent things. He is an ordinary high school student, just study hard. Whether the mermaid exists does not affect his goal of being admitted to the University of Tokyo.

After the water in the swimming pool was empty, seeing Yagi Miyuki also took a brush, Miro Nari didn't say anything anymore and jumped into the swimming pool with a bright smile.

Probably because of cleaning every week, there was not much dirt at the bottom of the pool. I brushed it casually for a few minutes, then washed it with water for a while, and the cleaning work was easily completed.

"Huh... I finally cleaned up."

Miro Nara stretched out her body, then turned on the device to fill the water into the swimming pool, and said with a smile: "Let's swim for a while, will Yagi want to go with you?"

"I'll forget it."

Yagi Miyuki shook his head, then said strangely: "You don't plan to reveal your tail again, are you?"

"Yeah!"

Miro Nara nodded happily.

Yagi Yuxiong pulled the corner of his mouth and said speechlessly: "It would be strange if you are not discovered like this, right?"

"But there is nothing we can do."

Miro Nara looked confused, "There is not such a big swimming pool at home, and I dare not expose my tail when I go to a crowded place, so only the school can satisfy me."

"Then I'll go back first."

Yagi Miyuki shook his head and reminded: "Be careful, don't be discovered again."

After saying that, Yagi Otsuki stopped staying and turned around and left the swimming pool where his worldview collapsed.

...

Yagi Otsuki walked out of the school in a daze. What he saw and heard just now was even more mentally ill than the attack of Senior Sister Ninomiya.

When he got home, even his sister's meticulous service made him feel numb. After solving everything, before nine o'clock, Yagi Yuyou climbed onto the bed, closed his eyes, and soon lost consciousness.

...

“Um…”

Yagi Miyou opened his eyes in a daze, glanced blankly around the dark scene he was in, sat up and glanced around, and found that this was his living room, and he was on the sofa.

"Um?"

Yagi Miyuki rubbed his eyes and felt a little drowsy in his mind, and he couldn't even do normal thinking.

"Yaki Jun, you're awake. Don't sleep on the sofa next time."

A gentle and familiar voice came, which caused Yagi Miyuki to look over subconsciously. What reflected in his eyes was a tall girl with a delicate face that could not be found in a slight flaw, wearing a simple plain dress.

"Senior Sister Ninomiya! Why are you in my house?"

Yagi Oyuki was so scared that he almost jumped up. Just as he was about to scream, his expression suddenly calmed down, and his emotions couldn't help but become calm. He blurted out in a strange way: "Oh, yes, Senior Sister Ninomiya and I got married after graduating from high school and are now living a sweet newlywed life."

There seems to be something wrong...

Yagi Mitsuki frowned slightly, and she always felt strange, but she didn't know what was wrong.

"It's been a long time since I said it."

Senior Sister Ninomiya's lips rose, her expression became ambiguous, and she whispered like temptation: "Come on, Yagi Jun."

"It's true that I haven't done it for a long time."

Yagi Miyou nodded with a natural look on his face.

“Yes.”

When did senior sister Ninomiya have a bundle of hemp ropes appear in her slender and white hands?

Looking at the senior sister who was approaching with a smile, Yagi Yuyou's instinctively rose in his heart, but he was quickly suppressed by strangeness like he had been the previous few times.

Before Yagi Otsuki could react, Ninomiya Ho had already used his skillful "rope art" and used to tie him up with a tortoise shell.

"Study, senior sister--"

Seeing Ninomiya Homori smiled and took out a whip with a morbid smile, it seemed that a nerve broke in Yagi's mind, and his fuzzy brain suddenly became clear!

“Ahhhhh——!”

Yagi Yuxing suddenly opened his eyes and jumped up from the bed! He was breathing heavily as if he had escaped from death!

"Huh! Huh... It's such an unprecedented nightmare!"

Yagi Yuyou slowly collapsed on the bed panting, picked up the phone beside his pillow and looked at it: "It's only seven o'clock? It's a rare weekend. I'll just stay in bed a little......"

Yagi Miyu's facial muscles suddenly stiffened, as if he had finally found something wrong. He slowly turned his head and looked at the bulging quilt beside him.

“Um…”

A gentle whisper suddenly sounded, and then a small head came out of the quilt, revealing a innocent face.

The girl rubbed her hazy eyes and looked at Yagi Miyuki, and said in a concerned tone: "Have you had a nightmare? Brother, you have been very worried since you came home yesterday, isn't it okay?"

"no--"

Yagi Yuyou looked at the girl who sat up from her bed in a daze and said, "Ochako, why are you on my bed?"

"You said this."

A gentle smile appeared on Yuchako's delicate and sweet face, and she blinked her bright big eyes and said, "Because my brother was in a state of dismay last night, I was a little concerned, so I came to your room to take a look. I didn't expect that my brother would fall asleep so early."

"Then does this have anything directly to do with you drilling into my bed?"

Looking at the complete pajamas on my sister, Yagi Yuxing felt a little relieved.

"Of course."

Yucha nodded naturally, "If you have a cute sister to sleep, your brother will sleep more at ease. Moreover, I haven't slept with my brother for a long time, so I miss you a little."

Yagi Miyuki rubbed his head and said helplessly: "Don't say strange things, you are not a child anymore, don't do this next time."

Yagi Miyuki's seemingly plain eyes were deeply alert.

Although it has been two days, he still hasn't adapted to his sister who has changed drastically. After all, before, the attitude of this stupid sister towards him can be said to be another extreme.
