Tokyo: Starting with the Shrine Maiden

"She's handling some matters at the Imperial Palace."

Kaoru Aizawa explained, "This ruin was first discovered by the Ōgosho, so there is a related agreement."

Haruhiko understood.

All relics are quite valuable.

The University of Tokyo must have paid a considerable price to obtain the development rights.

"Junior brother, since you have some free time, why don't you transform into a mermaid and let your senior sister study you?"

Kaoru Aizawa suddenly grabbed Haruhiko's hand, her eyes sparkling with excitement and anticipation.

She dared not study Chiyo's merman abilities, after all, she was her teacher, and her seniority and strength were undeniable.

Haruhiko was speechless.

Why hasn't this senior sister given up yet?

"do not worry."

Kaoru Aizawa said seriously, "I'm just taking a look. There's absolutely no danger."

"Okay, but just once."

Haruhiko hesitated for a moment, but ultimately could not resist the beautiful woman's pleading.

Moreover, Aizawa Kaoru treats him quite well, so it wouldn't hurt to let her see him.

"Junior brother, you're so kind!"

Kaoru Aizawa excitedly rushed over, hugged him tightly, and rubbed his head vigorously.

A soft yet suffocating feeling washed over me.

Fortunately, it only lasted a few seconds.

Haruhiko was able to breathe fresh air again.

"Let's go to the swimming pool."

Kaoru Aizawa stood up and pulled him toward the underground swimming pool.

Chiyome didn't react; she was still thinking about the problem.

Upon arriving at the swimming pool, Aizawa Kaoru stared intently at Haruhiko, waiting for his transformation.

Haruhiko had no choice but to jump into the water and use the skill on the Three Goddess Scepters.

Queen of Isohime!

A surge of spiritual energy quickly transformed into a cyan-blue color that enveloped Haruhiko.

Amidst the dazzling light, the clothes ripped apart, the legs transformed into a fish tail, and scales emerged.

"You can't see through it?"

A faint spiritual energy flickered in Aizawa Kaoru's eyes.

She had seen Haruhiko transform before, but he hadn't used any magic at the time and thought the light was just an ornament.

Now it seems that it did not, but rather it did indeed block the view.

How do we conduct the research?

Haruhiko raised his head and looked at Aizawa Kaoru standing on the shore.

From this angle, you can see her long, straight legs in black stockings even more clearly.

In terms of aesthetics, it's not as good as Tsuchimikado Mari.

As for Yukihime, she is more than just someone to admire.

"Besides the changes in your appearance, have there been any changes inside your body?"

Kaoru Aizawa squatted down, her black stockings taut, revealing her fleshy legs and the view beneath her bodycon skirt.

Haruhiko looked away, sensing the difference within himself.

He suddenly discovered that he could breathe through his scales, without needing to use his mouth or nose.

This means that his organs may have undergone a remarkable transformation.

"Respiratory system."

Haruhiko's gaze leaped over the valley floor and reached the snow-capped mountain, "Scales have replaced the mouth and nose."

"Any more?"

After pondering for a moment, Aizawa Kaoru asked again.

"His physical attributes have improved, equivalent to a third-tier demonic body."

Haruhiko shook his head and said, "I don't know about the others for now."

His Snow Woman Breathing Technique is almost at the third level, so he can feel the changes in his physical condition.

Considering that this skill is at the third tier, it's understandable.

Haruhiko suspects that once the Tide Gem of the Three Goddess Scepters is retrieved, it should be able to transform into the fifth-tier Queen of Isohime.

"Don't move."

Kaoru Aizawa reached out and stroked the scales on his fish tail.

Haruhiko trembled, feeling somewhat uneasy.

It's not that the scales themselves feel anything, but the skin connected to them will be touched.

Fortunately, there was no overreaction.

Haruhiko guessed that the fatal weakness of the Merfolk was not their scales.

Perhaps in some other location.

He suddenly thought of the pearl on Chiyo's navel.

But he himself did not transform into a mermaid.

Do not you know why.

It might be related to the fact that he is a player, but ultimately he is not a real merman.

"Junior brother, aren't the scales on your lower abdomen a little different?"

As Aizawa Kaoru spoke, she extended her right hand.

Because she was squatting by the pool, which was a little far away, her upper body leaned forward, causing her bodycon skirt to spread out and lift slightly.

"and many more!"

Startled, Haruhiko quickly backed away, saying, "No, not there!"

Kaoru Aizawa was slightly taken aback.

Fortunately, she was a married woman and understood why Haruhiko was in such a predicament.

"Is that so?"

Kaoru Aizawa had no choice but to give up touching him, a regretful expression on her face.

Haruhiko immediately breathed a sigh of relief.

He is a male merman, so naturally he has brothers.

For merfolk, scales are their clothing.

Whether it's underwear or outerwear, it's all the same.

"Senior sister, should we continue with the research?"

Haruhiko couldn't help but look at Aizawa Kaoru.

"Come here, let me take another look."

Seeing his somewhat strange expression, Aizawa Kaoru immediately burst out laughing.

Junior brother, this is so much fun!

With no other choice, Haruhiko stepped forward again.

Kaoru Aizawa's hands gradually moved upwards from the fish's tail, eventually reaching his chest.

She patted it and said, "It's not much different from humans, except the meat is better."

As she spoke, she remembered the grilled fish she had for lunch and couldn't help but lick her rosy lips.

"...?"

Haruhiko's heart skipped a beat.

Senior sister, what are you trying to do?

My mouth is watering!

"Okay, I have a general understanding now."

Aizawa Kaoru withdrew her hand and said, "Thank you for your cooperation, junior brother."
