**"Niko, hurry it up. We don't have much time."** He growled down the tunnel his companion was in the middle of excavating. It was times like this he'd wished he had Earth Release, his Water and Wind having very little use in shoring up their defenses. Grabbing the two other children, he'd drag them into the room with Koike and Yuki. Using the blunt force of all four of his tails, he'd try and help excavate the tunnel at a much faster pace. **"If you brats want to live, start digging!"** He commanded the others.

Time. If only he had more of it, damn. 

 Soft thuds echoing into his tunnel gave him goosebumps, not fully being able to distinguish what was what. This was no time to overthink, so he focused his chakra for a moment as his arms changed into paper sheets ripping off into the air in front of him. What was he making? A chakram, that would slice open this glass and make an opening for the Sarutobi to grab the girl and get the fuck out of here. 

 His paper could become just as hard as steel, and with his chakra control -or ninjutsu abilities- he could shape the edge to such a point, that with the speed the chakram will be moving at it should saw through the glass like wood. Hopefully.

 The chakram would gradually begin moving in a large circle motion to make an opening for Yasu, and he figured the water would push the opening out at some point and move the child closer to him. If the water started pouring out, he'd brace himself by using kinobori and the tunnel walls. He also had to be extra careful so his chakram did not hurt himself, or the girl.

Murano and company proceeded to begin burrowing their way through the walls. Outward and upward they went, and it was only a matter of moments before sunlight cracked through the stone and dirt. Which was just as well, since behind them, the rogues could hear the earthen wall break open, and a monstrous, hissing *ROAR* Echoed after them. They had moments, at best, before the Horror began its pursuit.

Haiku and Koike tumbled out to the surface, and waited for Yuki and Murano- but the third child, Ruiko, stayed in the tunnel. His knobby, malformed flesh had no issue lumbering through the passage. No, he stood his ground. One of his eyes, sagging on his underside, glanced at the others. A thick substance poured from the eye, sticky but clear like water. It sapped onto the ground.

"Ruiko-kun-" Koike started, and took a step forward, but Haiku grabbed her arm and hissed, "We have to run; that thing will *Kill* Us. Ruiko's making his choice."


Meanwhile, underground and on the other side of the lab, Yasu successfully cut away the glass. In an instant, water began rushing out into the tunnel, saturating the wood and the dirt. With it came the dark figure. She - for its humanoid features were vaguely feminine - was, for lack of better term, a fish person. A scaly body that ended in a tail, and vestigial arms that might've been gills if not for the fingers coming off of them. Her head was the most recognisable part of her body: pale blue and lined with gills, not unlike a Hoshigaki's likeness. Thin, coarse hair lined her head and trailed down her body before coming and hardening into a dorsal fin.

As the water rushed out and she was exposed to air, she let out a strangled, gasping noise. Her arm-fins clawed uselessly in the air. Her wide, all-white eyes lolled about in their sockets.
