"There's no danger!" Nai Hyuga stepped tentatively onto the second floor.
Yui followed behind her. Both remained alert; their surroundings were pitch-black, unlike the brightly lit first floor.
They used their Byakugan to inspect the area carefully. Only after finding nothing unusual did they relax their guard.
"Why isn't there anything here?" Yui surveyed their surroundings, puzzled. "If I remember correctly, I sensed something standing here not long ago."
"And now it's disappeared..."
Nai Hyuga shared Yui's confusion. "Could it have gone upstairs?"
"Yes! That's possible!" Yui replied. After considering it for a moment, she added, "I think we should search the second floor. It might be hiding in some corner."
She voiced her concerns, and Nai Hyuga nodded in agreement after listening. "All right..."
The two split up and searched opposite sides.
The second floor of the Stone Tower was narrower than the first. Yui looked around. Unlike the empty first floor, this level was packed with square wooden crates, offering plenty of places to hide.
Yui stared at the wooden crate before her for a while, then made up her mind, reached out, and squeezed it.

"This crate... must have been here for a long time... After all those years, just a squeeze was enough to break it!"
As the crate disintegrated, its contents were exposed.
Yui's gaze fell on a white object buried beneath the wood fragments, and her expression briefly froze. "It's something made from the same material as the Stone Tower."
Delight rose within her. She hadn't expected to find something like this so quickly. Taking a deep breath, she suppressed her excitement.
The more things went like this, the more
