Tsukasa and his friends, Rui, Akito, and Toya went to investigate an abandoned building because they do this for fun and views.

Today, they went to investigate an abandoned hospital that was closed 20 years ago.

Tsukasa went with his friend Rui and his other two friends Toya and Akito went to the other side of the hospital.

Rui was holding a camera and Tsukasa was behind him.

"Rui, do you think...we might see a ghost?"

Tsukasa asked, jokingly.
