Outside the underground laboratory of the Tachibana dessert shop, the corridor was empty, but its door was suddenly opened, and then the door frame was boundary, and a figure stepped into reality from outside the boundary, manifesting as a physical entity inside the door.

This figure is Hidaka Midori, who has just gotten off the Zio-Liner.

"Kacha!"

The door of the laboratory was closed behind him, and Hidaka Midori, who was holding a backpack in his hand, stood at the door in a daze, looking at the familiar laboratory in front of him, and his mood was extremely uneasy.

"Really...... It's incredible! ”

This kind of technology to open a stable passage between reality and subspace to travel freely, even if she had experienced it once before when Zio-Liner arrived at the 9-to-5 class, but after experiencing it again, she really felt very shocked.

Putting down the backpack he was carrying, Midori Hidaka turned around, looked at the doorknob and paused for a moment, then raised his hand, grasped the doorknob and turned the door open.

With the slight friction sound of the door shaft turning, the scene outside the door came into view, and Hidaka's heart gradually turned from nervous to dumb.

"Oh, really, what am I thinking......"

How can it be so easy to connect to subspace or something?

The reality outside the door was an empty hallway, not some rainbow-colored desert space.

She chuckled, shook her head, turned to remove her lab coat from the hanger, put it on, walked out of the lab and closed the door, and walked out of the hallway.

……

……

The first floor of the Tachibana dessert shop.

At this time, the store has long been devoid of customers.

But it was clear that it had already been opened, but the door of the store was not locked, and the Tachibana sisters were still waiting in front of the entrance, staring at the door with two pairs of eyes.

They were waiting for Tachibana.

And have been waiting for a while.

However......

Tachibana Sejiro still hasn't arrived.

“emmm……”

Tachibana asked with a deep groan.

"Haven't you arrived yet?"

"Come on."

Tachibana Hinaka said with a hesitant expression.

But this answer obviously does not satisfy Tachibana incense.

She immediately asked, "How long is it going to be soon?" ”

"Ah......h

Hearing this, Tachibana Hinata looked down at the time on her phone, and said quite tangledly.

"According to Daddy's footsteps, it's really time to arrive...... Could it be that something is delaying on the way? ”

This answer full of history made Tachibana Kasumi suddenly squint.

"Day! Cuisine! Good! ”

"Woo~~~"

Hearing this, Tachibana Hinata immediately raised her hand, reflexively made a defensive gesture, and hurriedly assured.

"It's almost there! It's really almost there! Wait a little longer...... Just wait a little longer! ”

Not to mention, Tachibana Hinata is lucky, and this time it was finally drawn to the lottery.

"Why wait a little longer?"

The door of the store was pushed open from the outside, and Tachibana asked as he walked in through the door.

Hearing this, whether it is the fragrance of Tachibana or the good day of Tachibana, the action can't help but stagnate.

They all glanced at Tachibana at the same time, and then they all reacted differently.

"Hey~~"

Hinata Tachibana put down her defensive hand and smiled with a raised eyebrow.

"Hmph~"

Tachibana Xiangsu actually looked at her sister and smiled, but immediately deliberately straightened her face and gave her a look of "I'll let you go this time".

“？”

Tachibana, who didn't understand the encrypted call between Tachibana Kasumi and Tachibana Hinata Kanaka, shook his head and looked behind them.

"It's already here, little green, but why are you the only one? What about the little waterfowl? ”

He asked Hidaka Midori, who was wearing a white coat, lifted the short curtain, and pushed the door to walk out of the back of the store.

It's just that he asked, and before Hidaka Midori could speak, Kasumi Tachibana and Hinata Tachibana screamed first.

"Little Green Sister!

？ ”

They immediately turned around, their expressions all staring at Hidaka Midori in great shock.

"When did you come?"

The reaction of Tachibana Kasumi and Tachibana Hinata successfully made Tachibana's expression strange.

"Didn't you know she was coming?"

Tachibana Kasumi and Tachibana Hinaka glanced at each other, both shaking their heads.

"I don't know."

Then, along with Tachibana Shichiro, the three of them, father and daughter, with three pairs of eyes, all looked at Hidaka Midori behind them with an inquiring gaze.

Hidaka Midori was silent for a moment, and said slowly: "Don't hide it, I just arrived." ”

However, as soon as this remark came out, it was immediately refuted loudly by Tachibana Kasumi and Tachibana Hinaka.

"How is that possible!? We've been staying here at the door all along! ”

So if such a big living person really just arrived, how could they not notice?

Hidaka Midori can understand the doubts in Tachibana Kasumi and Tachibana Hinata at this time, after all, her experience is indeed a bit beyond common sense.

She said, "But what if...... Didn't I come in through the door? ”

From this point on, Midori Hidaka recounted her previous short journey with a bit of fantasy.

After listening, the scene was silent.

After a moment, Tachibana took a deep breath and exhaled, exclaiming, "A tram that runs stably between subspace and reality...... It's incredible! It seems that the Historical Authority has not only the power of the mysterious side, but also the power of the matching technology side. ”

This kind of power is really intimidating.

But on the contrary, as a cooperative organization of the Historical Administration, he couldn't help but breathe a sigh of relief.

Because the deeper the background of the Historical Authority, the more reliable the plan they put forward to suppress the big snake, get rid of the aliens, and revise history.

In this way, they just have to do what they can.

Thinking like this, Tachibana Shiro breathed a sigh of relief again and asked Hidaka Midori, "Is there anything you want to ask about the thing I asked you to do?" ”

Midori Hidaka nodded, "I do have a question I want to ask." ”

Sonic Amplification Sword: Armored Sonic Blade, the most powerful weapon in history developed by the Mengshi Order.

However, due to the special fluctuations of the blade that are too powerful and beyond the limits of human beings, even if it was snatched away by the Super Boy for a time, and then coincidentally suppressed its fluctuations by the kimono men and women, there are no ghosts in the Mengshi organization who can use it.

Therefore, even though it is the most powerful weapon developed by the Mengshi organization so far, it was still labeled as a "failure", and finally put on hold in Hidaka Midori's laboratory, and has been sealed in the dust to this day.

It's not surprising that the Mengshi Organization thinks of it when it needs power, but it is a little difficult to understand Tachibana's instructions.

- Unblock the WaveBlade and continue to amplify its power after tuning its Wave to its maximum!

Yes, not to suppress, but to continue to strengthen a weapon that is too powerful for anyone to use...... Is this reasonable?

】

To this question, Tachibana Sejiro answered Hidaka Midori like this.

"Don't worry."

He recalled Woz's expression and tone when he made this request at the meeting, and said with emotion.

"It's not that no one really has access to it, it's that it hasn't met the one who can.

"Just like the holy sword in the story that no one can draw, once someone pulls it out, it is the beginning of a new legend."

……

……

Meanwhile.

Onizuka Shrine.

The sound of the taiko drums is endless.
