Editing Seirei Tsukai no Blade Dance:Volume12 Chapter9 (section)

===Part 7===

Drip, drip, drip&mdash;

Kamito's group walked along the passage to the underground facility amidst sounds of water dripping.

Unattended for decades, the underground facility was very decrepit already. The ceiling had collapsed in many places, forming piles of debris.

"The air is very musty, almost as though it was left behind from the darkness of the Ranbal War."

Walking in front, Ellis gave her comment.

"To me, this actually feels nostalgic instead."

Kamito was long used to this kind of suffocating atmosphere.

The presence of death, impossible to dispel&mdash;Just like at the Instructional School.

"Research on Cursed Armament Seals was apparently conducted here."

"No way, Cursed Armament Seal research took place even underground below the sacred Academy?"

"Students from over there were apparently used for experiments. Of course, they were volunteers."

Hearing Lurie's words, Ellis bit her lip with a complicated expression on her face.

"Why didn't the Empire scrap that kind of place?"

"Probably impossible to scrap due to its sheer size. This was a facility originally rebuilt from ancient ruins. Most likely, even in the army itself, no one knows fully how large it actually is&mdash;"

At this moment, walking in front, Ellis stopped in the center of a spacious hall.

"&mdash;Over here. The coordinates for the temple above ground."

"Here?"

Kamito looked around the temple's hall, all surrounded by walls of rock.

"I don't see anything?"

There was nothing except abandoned experimental apparatus and piles of debris.

There was not a single sign of the Demon Slayer.

"Does your spirit seal have any reaction?"

"..."

Kamito closed his eyes and focused his attention to the spirit seal on his right hand.

"It feels like I can sense a presence..."

"Don't worry. The Burial Chamber is a magical and special dimension and does not exist at physical coordinates&mdash;So, it will appear so long as you have a need for it."

"So long as I have a need for it...?"

Hearing Lurie's calm explanation, Kamito felt a strange sense of dissonance and turned his head to look back.

"Yes, for example&mdash;"

Lurie smiled tenderly.

"When it senses that your life is in danger, yes?"

"&mdash;Eh?"

In the next instant, a blade stabbed into Kamito's chest.
