To fool Naomi Misora, he acted a bit strange during Naomi and L's investigation, calling himself , with "Rue" being an anagram of the Japanese pronunciation of , and Ryuzaki being a nickname L later adopts. He was always in heavy makeup when with Naomi, so his true appearance is unknown. He killed 3 victims, Backyard Bottomslash, Quarter Queen, and Believe Bridesmaid, while leaving clues at each murder scene for Naomi Misora to "solve." In reality, he himself led her to each conclusion she made.
