Sakayanagi's Secret Message-As Vice President, He Understands It Well! (Part 2)

"I'll hold it down," Archangel Ichinose said thoughtfully.

With Ichinose's help, the stone door blocking everyone's path was raised by the mechanism.

Almost the instant the stone door rose, a large rush of water surged toward them, quickly rising from ankle-deep to knee-deep.

"Don't move forward for now," Hachiman said. "We can't determine how deep the pool ahead is."
