(The Golden Pain)
At the library in David's castle, the gang was reading a few books when all the sudden, the gang heard thudding sounds from the foyer's stairs as Leo sees David at the bottom of the stairs and in pain as he starts glowing gold all over his body, Rocket scans David's body as he found no actual pain inside him as David starts turning into the Golden Prince and back to normal at no control. As David changes out of control, a book magically flies above the gang as Annie grabs it, as it was a story of a legendary warrior of history: The Phoenix Warrior, a magic entity with the power of an inferno as the gang reads it until June comforts David in his condition as June noticed that she didn't feel any pain as If it is only affecting David himself as the others read the magic book. The gang learns that the Firebird that they once rescued long ago in Russia is involved in the story, as they see a golden human that somehow combined with the Firebird, becoming the Phoenix Warrior as the gang remembers the time David was warned by a magical fairy about the golden power inside a mortal with a high risk of death as they must find the Firebird to help David. As the gang boards Rocket, David body somehow goes numb as he can't move from his golden powers as if his strength has been drained until he faints to the floor, Rocket brings out a giant spatula as he carries David inside as Rocket flies the gang back to Russia as David still groans in pain as June comforts him by holding his hand and checking his pulse until June hugs him. Will the gang save David from his mysterious pain?
