Just like the singing, Satogi was the last one to notice the next mysterious voice that came out of the unknown. He had to be stopped by Sanae's attached arm and heard the crying, which sounded like a woman. Satogi was now more cautious then worried, even though the sound should be investigated.
"How many people are in these woods with us? It's very odd." Even with how close they were to the shrine he doubted there would be anyone out this late besides the group of teenagers. Satogi wasn't surprised when Sanae ran off, it was part of her being to help others. What did catch him off guard was Yukiko leaving him there alone and running off towards the shrine.
He knows she wanted him to help Sanae but he was split between the two. Finally deciding, he ran off after Sanae. "Please let this be the right decision!" The whole moment reminded him of one of those dating simulators with choices that changed the story. Hopefully he had just picked a good route or he might hate himself later.
Upon coming to the clearing he skids to a stop behind Sanae, hoping he hadn't knocked into her. The woman who had been crying was sitting on the ground as if she had fallen. She looked older than the highschoolers, but Satogi had no idea what age to put her at. For the most part he stayed behind Sanae and waited for when he might be useful.
