Editing The Unexplored Summon Blood Sign:Volume2 Chapter4 (section)

===Part 6===

Even though Kyousuke had prepared himself for a high pressure environment, there was only so much he could do on the fly. However, he could not float while inside the protective circle. As soon as the battle ended, he discarded the Chain time, returning Librarian-chan to her human form and removing the circle that prevented him from swimming. His vision immediately shook.

He just barely remained conscious.

That was the most his safety measure had bought him.

“…”

He clenched his teeth and grabbed the arm of the assassin floating at the bottom of the ocean. The boy did not put up any kind of resistance. When a summoner or vessel lost, they entered a state of mental shock similar to seeing the god they worshipped slaughtered before their eyes and that state would continue for more than twenty-four hours. They became puppets that did anything they were told, but he would definitely drown if left like this.

Kyousuke swam toward the surface.

Librarian-chan was a slender girl again and she was already swimming up as well. He had instructed her to keep the fight on the upper edge of the Artificial Sacred Ground. More accurately, he had told her to keep the lower position so she could drive Student Council President Benikomichi Fuuki ever higher and keep her at the ceiling of the Artificial Sacred Ground.

Artificial Sacred Grounds were twenty meter cubes by default, so at a depth of thirty meters, the top would be about ten meters deep. That was shallow enough to keep the water pressure from crushing her.

Librarian-chan grabbed Benikomichi Fuuki’s arm because the girl was still suffering from the water pressure (and had become a zombie in the original sense of the word after the shock of losing).

Kyousuke swam after them, but a dull pain ran through his head. He felt nauseous, like a magnified version of carsickness.

(Dammit… I have a light case of decompression sickness…)

A rapid change from low to high pressure was a problem, but the opposite was also a problem. The nitrogen in the blood would form bubbles that could cause headaches, nausea, internal bleeding, etc. The symptoms were known as decompression sickness or the bends.

However, he could not stay underwater forever.

He clenched his teeth and forced down the urge to vomit as he stuck his head out from the water.

If he had been about twenty meters deeper, the symptoms would have been more severe and may have killed him.

“Bwah!!”

“Wait, Shiroyama-kun, what is that!? Your eyes are all bloodshot and they’re shedding bloody tears…”

“I’m lucky that’s all it is. More importantly, let’s find somewhere to get out of the water. We can’t float forever with this baggage weighing us down. And it’ll probably get more troublesome once they come to.”

To make sure the dazed summoner and vessel did not drown, Kyousuke and Librarian-chan placed them on their backs and supported them from below as they swam. They felt like otters, but they finally arrived at one of the pillars holding up the high school’s midair float and climbed up using the staircase wrapping around it like ivy.

Librarian-chan looked up while carrying the student council president on her back.

“W-we really messed up our school, didn’t we?”

“Maybe we should be glad you’ve calmed down enough to be worried about that,” spat out Kyousuke.

That summoner and vessel pair had their origins in the summoner known as Telomere’s End.

They had planned to create a world without death.

That had all been stopped now that no one remained to complete the final ignition. The world built on the hatred and acceptance of human death would not be destroyed overnight.

It was all over.

For the time being, anyway.
