Riley is one of Yamaki's two main scientists in Hypnos, monitoring Wild Ones and Devas for him alongside Tally. She also goes to Takato's bakery all the time to buy bread and day-old bagels. She has red hair.

Though Hypnos was initially antagonistic to the tamers, Yamaki, Riley, Tally, and other Hypnos scientists later helped them out during their quest in the digital world and battle with the D-Reaper.
