Chapter 1

Hida Kizuna exited to the corridor with effort to not raise a loud sound.

It was late at night.

The hand of the clock had already passed through twelve.

However, Kizuna was walking exultantly with towel on shoulder towards the elevator hall wearing his sandal. His clothing was also still his casual clothes of T-shirt and short pants.

He was waiting until the time reached this point.

His heart danced.

A smile was naturally formed on Kizuna's lips.

Finally, the day where he could enter the large baths had come!

This place was the student dormitory of Ataraxia. It was named as a dormitory, but the interior that kept getting mistaken with a high class hotel, like the corridor that Kizuna was currently walking, the carpet with luxurious fur and elegant wallpaper, calming indirect lighting, the pictures and decorative plants, all of those were of a quality that was not like a student dormitory at all.

Although, all of those were because this floor was of exclusive use for the Amaterasu team.

The one fighting the AU's magic weapons wearing the Heart Hybrid Gear, was the Amaterasu. For them who were shouldering such dangerous role, they were receiving a suitable treatment for that.

The other floors were not as extravagant as this floor, there was not even a private bathroom inside the rooms of the underclassmen.

That was why, there was a large bathroom installed in this dormitory.

On the contrary, there was an excellent bathroom inside Kizuna's room, so he had no chance to enter the large bathroom.

Even before that, this place was a female dormitory.

Naturally, the large bathroom was for females' exclusive use.

For the male student Kizuna to enter this female dormitory was also a strange story, but it was related with Kizuna's special mission that was [Heart Hybrid].

Heart Hybrid was an act that recovered the energy called Hybrid Count by a male and a female possessing Heart Hybrid Gear, joining their hearts and bodies into one and shared their affection and pleasure.

Saying it bluntly, by doing erotic things that made each others' feelings get excited, the energy would be recovered, that was what it meant.

Due to that kind of reason, Kizuna was encouraged to have illicit sexual relationship. Then, so that a mistaken occurrence could occur more easily, Kizuna was entered to live in the female dormitory with the arrangement of the school side.

'――They are insane.'

It was none other than Kizuna himself who thought that.

Whether the school side gave him authorization or not, there was no way he could enter the women's bath.

But, today was special.

After all, the hot water of the bath today was from a hot spring.

They discovered a hot spring at the bottom of the sea, then the guys from the technology department pulled up the hot water and supplied it to the large bath of the dormitory.

However, that was limited to today.

From the beginning he was thinking of wanting to enter the dormitory's spacious bath, now that there was this chance, he would absolutely enter, that was his thinking.

"Then, it's fine for you to enter this evening. The cleaning after midnight will be postponed. Use it to your heart's content until morning."

Kizuna's big sister, Hida Reiri spoke like that to Kizuna.

With a single order of the commander of Ataraxia, tonight the bath was reserved for Kizuna.

And then currently, he was heading to the large bathroom in this midnight where there was no presence of people.

Perhaps it would be fine for him to not go through all this trouble entering the female dormitory's bath by going to the male dormitory. However, he felt a danger to his life of trying to do that.

There were a lot of boys that envied Kizuna's blessed(?) mission. The bunches who had their envious feeling sublimated to become resentment and hatred were not few in number. To intrude into the headquarters of such boys stark naked was a suicidal act.

Descending to the underground by elevator, he finally stood in front of the large bathroom.

Before the large sliding door, a sign that was written with large [ゆ] character was hung down. (TN: That character means hot water, read as 'yu')

Slipping through the sign, he opened the door noisily, the lighting was shining in glitters. The electricity was left on, but the place was deserted with no presence of humans that could be sensed. Only the sound of flowing hot water was audible, there was not even the sound of someone entering the bath.

After Kizuna closed the door, he took off his sandals and went up to the dressing room. He went through the lining up lockers on the left and right, then he suddenly looked to the side.

A white and large ass, was shaking like jelly.

Time stopped.

――Eh?

――Why?

It was the back figure of a beautiful girl.

With only a bath towel covering the breasts, a completely defenseless back figure was exposed.

Under the wet long black hair, was a constricted waist. From there the hips was greatly jutting out, continuing toward the slender and well-proportioned legs. The voluminous ass was drawing a circular curve at the base of the thighs.

'――This is bad.'

This was obviously an accident, but he had the feeling it was going to become a serious affair if he was noticed. He should get out right now.

Kizuna backed off carefully so that no sound would come out.

If he was seen by people in this kind of timing, a stigma of pervert would undoubtedly get forced on him. Especially in the worst case that even Himekawa also discovered this――

Just a little bit more, when it was just a little bit more, that girl was turning around.

'――Wha-!?'

It was exactly that Himekawa Hayuru who was staring at Kizuna.

Kizuna froze.

Himekawa too, she didn't move as if being petrified.

On her skin that was colored faintly by pink color, the drops of hot water were shining.

The drops on her bosom were sliding down on her smooth skin, then it was absorbed into the valley of her breasts.

Her wet long black hair was clinging to her cheek and shoulders, it looked really sexy on her.

Even while his eyes were stolen by Himekawa's figure that was just rising from the bath, his head was desperately thinking about the situation.

'――Why is Himekawa here?'

'――This is strange isn't it? Isn't this place reserved for me?'

'――The person I don't want to get caught by the most, is right here!'

...His thinking didn't result in anything.

Himekawa's face was flushing before his eyes.

And then, her body was beginning to tremble little by little.

"Yo, you see here, Hime――"

"KYAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA-!!"

A scream like a torn silk reverberated inside the dormitory.

"Wha-? Wh, wha, what's with this!? Thi, this, molester! Pervert! Just what in the world are you thinking-!!"

Kizuna's head was also completely panicked.

"Tha, that's, that's my line here-! Just why is Himekawa in this kind of place!?"

Steam was rising from Himekawa's body that was warmed by the hot spring water. Right now such thing looked like nothing but an aura of rage.

Her eyes opened widely all of a sudden.

"This place is... the women's bath so obviously I'm here!!"

'――What she said, is the most correct.'

"No-! That's correct but! I know but!"

Himekawa's eyes were burning in rage.

"As I thought, so you are coming to peep aren't you? This is a contemptible shameless act."

"Wa, wait! Calm down, I oppose violence!"

"Neros!!"

Himekawa's body was wrapped in red light. That was the radiance that the Core installed inside Himekawa's body emitted. The red light particles were gathering on the body surface and changing into physical material. The process was completely like magic.

After the radiance was completely converted into physical material, the light settled down. In exchange, the created armor was equipped on Himekawa's body.

The luster that looked wet was pretty on the red colored armor. Its slender form was delicate, but it also possessed tenacity, giving off the impression like a sharp katana.

That was Himekawa Hayuru's Heart Hybrid Gear, [Neros].
