"Hey, where did it go?" Yoshida Ayumi froze for a moment, then said disappointedly, "It must have been too long ago. The imprint faded away..."
"An imprint?" Officer Sato understood. "You mean when you fell to the ground, you accidentally pressed down on that thing, leaving its mark on your palm?"

Officer Sato turned to look, but saw no suspicious person.
