|“So tell us about the Key-Tana, Okino. You said it's in a maze?”|
“Hai. Guarded by a fearsome beast. A dragon.”
|— Nya and Okino, "The Glitch"|
When the ninja and Okino spotted the Red Dragon with the Purple Key-Tana, Jay attempted to grab it, but only for the Red Dragon to wake up and attack the ninja. However, when Okino told the ninja about the Red Dragon's weak spot, the ninja were able to weaken it. Moments later, when the Red Dragon was about to attack Lloyd, Jay used the Key-Tana and defeat the Red Dragon with it.
After reaching the fire wall, Jay inserts all of the Key-Tanas in their respective holes.
