This Is What Deep-Sea Terror Really Looks Like

Koyasu Tsubame covered her chest with both hands, looking visibly nervous and uneasy. "When I opened my eyes, I found the whole room flooded. My phone was gone, too, so I couldn't call anyone, and I don't remember where this place is..."

"I still have to find the others," Amamiya Natsuki said. "Let Kaguya explain it to you."

Koyasu Tsubame's eyes widened. Only then did she notice the figure standing behind Amamiya Natsuki. It was Shinomiya Kaguya. "Is that really Kaguya?"

They were both popular beauties at school. Though they had never interacted, they knew of each other.

Shinomiya Kaguya parted her pink lips, unsure whether she should say anything. After all, the story sounded unbelievable no matter how she put it.

"Let's talk somewhere else," Amamiya Natsuki said
