When we arrived at Grandmother's house, it was pitch-black.
"I am going to nead back now. Please, hand the cucumbers to grandmother," Kappa said.

"Ok, I will."
Yuta noded.

Kappa turned his back on Yuta and was going to return to the river.
Yuta stopped him.
"When does a yokai appear?"

Kappa answered.
"At the time when I met you when it comes to start to get dark".

"Can I meet you tomorrow?,"
Yuta asked.
"Well...."
Kappa answered while looking puzzled.
