“I CAN GIVE YOU A SMILE THAT WILL LAST FOREVER!”

Junior high school student Eisuke Sasaki has been found dead in a chilling fashion, with a smiley-faced paper bag over his head.
This unsettling visage bears a striking resemblance to a recurring clue in a string of unsolved murders from 18 years ago – as well as the urban legend Emio, aka the Smiling Man, a serial killer said to grant his victims “a smile that will last forever”.
