"We can investigate his motive later," said Jeffrey. "But the most important thing now is to get rid of the ghost so that it will stop its haunting. That's what Tiffany's father asked us to do, isn't it?"
"You're right!" answered Shaun. "The school cannot possibly return to normal if Yuki doesn't leave. Now the problem is: in what way are we going to remove the spirit? Do we want to do this peacefully, i.e. by persuading her to ascend to heaven by herself; or shall we do it forcefully?"
"I'd prefer if Yuki is willing to let go of her own resentment," replied Blythe. "That'd be the best method."
"I agree," said Shaun. "Let's go find her and see if we can persuade her. But where has she gone?"
"I saw her going up the stairs to the top floor," answered Jeffrey.
Nevertheless, Yuki's ghost was nowhere to be found when the detectives arrived at the top floor.
