You went on a road trip to somewhere Tengen had planned. As smooth as things were going, Kyojuro saw a glimps of a creepy woman by the roadside. This was subsided once you guys took a stop to eat and shop but then back on the road, now Obanai too saw her. You wanted to figure this out, especially after Kyojuro saw a glimps of her at the hotsprings aswell.

After that, Tengen thought it would be cool to explore a forest at night and take pictures only with his phone's flashlight. He was clicking pictures and draining out the battery.

Sanemi: grabs Tengen's collar "You idiot. Stop taking pictures!"

Tengen: "Hey it's too thrilling to not take pictures right now-"

his phone's battery runs out and the flashlight also went out with it.
