"This—how could this be!"

Even powerful beings like Yukari Yakumo and Yuuka Kazami hadn't anticipated this at all.

Rather, it's more accurate to say that this is not an impossible thing at all.

"What kind of bullshit joke is this...!"

Boom——! !

Accelerator stomped through the ground in time and arrived in front of the two at top speed.

He didn't even have time to manipulate the wind or other vectors; he simply raised his hands and reached out without hesitation to touch the two women's arms.

With just a touch, the phantom-like arm shattered instantly.

After finishing, he turned his body around in mid-air again and kicked the cube's barrier with a back kick.

Power flows into it through dimensions and space.

After manipulating the vectors on the surface of the barrier, Accelerator poured a terrifying force, equivalent to a nuclear weapon, into the barrier's interior—and kicked it into the sky in one go, preventing its explosive power from destroying the surrounding area.

But the result was completely unexpected.

Has anyone told you something?

"That was your movement just now; it was far too slow."

then.

The barrier that had flown into the air was completely shattered.

—The latitude of that surrounding area began to completely distort and change.

"What?"

"what happened?"

This has begun to be a situation that neither Yukari Yakumo nor Yuuka Kazami can comprehend.

Under their gaze, something surged out from inside the barrier that exploded in the air.

It was not a human body, nor any physical form, but rather clumps of pitch-black, murky matter.

Surprisingly, the sound just now came from inside this murky mass.

"For me, being touched is equivalent to absorbing power... Just now, I completely absorbed the last two powers I needed."

The last two forces…

Could this be the reason why that thing intended to touch Yukari Yakumo and Yuuka Kazami in the first place?

"You... from the very beginning, from the very beginning when you were with the Saigyou Ayakashi, was this your goal?"

It's a very strange thing to talk about.

Why did the demon, upon arriving in Gensokyo, intend to first possess Saigyou Ayakashi and then devour Saigyouji Yuyuko as well?

Why did it suddenly appear inside the Scarlet Devil Mansion and then leave? Why did it suddenly erode the false moon prepared by Eirin Yagokoro? Why did it then appear on the moon?

And why it is here now, saying these things.

"The Hakurei Shrine Maiden, the Youkai of the Boundary, the Youkai of the Four Seasons, the Prince on the Moon..."

"And you, the strongest Level 5 superpowered being who can manipulate all vector directions."

The truth is right before our eyes.

But the truth was not what Accelerator wanted to know at all.

"The power within each of you can become nourishment for me... that is, the tools that allow me to return."

"Returning...?"

"It's just resurrection, you idiot."

bass--!!

The distorted sound echoed across the sky.

After the origin of all this, the sky of Gensokyo shattered.

The sky was like glass, shattering piece by piece, centered on that shadow, in all directions.

finally.

What was taking shape in front of him was a shadow that Accelerator never wanted to see again.

The smoke dispersed.

Covering the black and red scaly skin were streaks of blood, resembling Sanskrit characters.

Larger, black and red wings, than the previous pair, fully unfurled behind him.

Beneath a helmet-like face, scarlet eyes were fully open.

"...Long time no see, Accelerator."

DO Abis.

The demon representing the abyss has been fully resurrected.

"Compared to before, I have now achieved a further improvement in rationality... Being able to talk to you normally like this is probably the best example of that."

"If a living being wants to demonstrate its strongest power, how should it do so? Is it to prove something by destroying it? No, no, I now know very well how to prove that I am the strongest."

"Only when you can use power strong enough to destroy countless universes to catch a fly that's only the size of a grain of rice and keep it alive can you truly prove your strength, right?"

A demon is not such a terrible thing.

What's truly terrifying is that this demon possesses sufficient rationality, and even considerable intelligence.

Once all of this actually happened, Accelerator was very clear about what the situation was.

--end.

Both Accelerator and Yukari Yakumo seem to have understood this point.

"What are you saying to yourself over there?"

boom--! !

A beam of white-green light shot out instantly from beside DO Apis.

Next, Kazami Yuuka slowly rose to her feet.

"Judging from what you just said, it seems that the power and means we possess have become the key to your resurrection."

She fully unfolded the parasol in front of her.

The immense demonic and magical power converged, forming a tangible shadow right beside Yuuka Kazami.

Complete copy.

That figure, which was exactly the same as hers, was essentially the same level of strength.

"Since the whole goal is to lure you out—"

"Wait! It's Kazami Yuuka!!"

Yukari Yakumo, who noticed all of this in time, immediately called out to her.

However, the power of this Lord of Flowers in All Seasons has already reached its limit.

The two figures raised the parasol together, concentrating their power at the very tip of the parasol.

That would be the strongest possible output she could prepare.

--boom.

The magical cannon, capable of slicing through two-quarters of Gensokyo, was unleashed.

The two beams of light converged and then transformed into a larger-scale magic cannon.

The white-green beam of light, with an aura that seemed to devour the entire Gensokyo, continued its relentless advance straight ahead without the slightest pause.

As they approached the demon's body in such a straight line—

then.

The demon representing the abyss made the simplest move in an instant.

It blinked its eyes gently.

Bang! ! ! !

Yuuka Kazami's magical cannon, and the surrounding spacetime, dimensions, and dimensions—

They were all devastated.

—Not only that, the aftershocks of that fluctuation caused profound and devastating damage to the interior of the entire universe, from the inside out to deeper and then to unimaginable depths.

After a series of blows, an outcome that even Accelerator could not have foreseen occurred.

Boom!! Space shattered, and from the other side of the space, all the girls who were playing on the beach fell here.

"pain--!"

"Whoa! W-what happened..."

"My butt hurts so much... This isn't a beach...?"

The girl who was still wearing a swimsuit, as well as Accelerator and Yukari Yakumo herself.

And then there's Kazami Yuuka, who completely forgot to blink while suspended in mid-air, unable to concentrate even when the parasol in her hand fell.

Her mouth was agape and her eyes were wide open. Her clones vanished without even being attacked, and she herself landed on the ground.

"What's wrong."

"DO Abis," he said, looking at her calmly.

"It's just a blink of an eye, anyone can do that, right?"

It's worse than I imagined.

No—this is beyond description.

'It's several times stronger than when I last saw it... No, I probably—can't even calculate that difference...!'

If we compare the former DO Appis with the current DO Appis...

All Accelerator could think of was the difference between the number 1 and the number of grains of sand in the Ganges.

When the first person was about to set off, he found that his palms were completely soaked with sweat.

Even my throat started to dry out.

"Now, are there any more questions?"

That wasn't a warning, nor was it said for any particular purpose.

It simply said what it wanted to say.

"Where...where did you come from?"

"Something I've never seen before suddenly appeared in the sky—Reimu! She even managed to smash the sky!"

"Ugh... I know! Another anomaly... This is so troublesome."

"Let's all go together this time."

"If we can get this sorted out quickly, we can get back to the beach sooner, right? It's so hot..."

The girls, who hadn't yet received the information, continued to ramble on about their own unrealistic, sweet daydreams.

"Yukari Yakumo... Hey!"

When Accelerator looked at the other person, he found that she was no longer responding.

The greatest mind of Gensokyo, the sage of youkai.

At this moment, she seemed to have forgotten herself, her expression utterly empty, and she simply straddled the seat.

“…You damned bastard!!”

Accelerator had no other ideas left.

He clenched his fists without hesitation and widened his eyes.
