Actually, Ryuki wasn't worried about Yuta. From his gift, he knew that he was fine and might return soon.
However, he was curious about the banana device.
"What is that?" Ryuki asked.
"It's a device that helps us track yokai," Ami said as Nana peeled the banana. Inside was the long, dark banana.
This thing really gives others dirty thoughts.
Ryuki thought. He saw Nana holding the banana and pointing in front of her. Nothing changed when she started moving the banana to the right, and she kept on moving until the banana pointed at him.
When it did, the banana light up, and then he felt his vision getting blurry. He saw two bright things, and when his vision returned, he turned his head and saw a woman.
