Seen episode 40; given what happens, Nossan seems to point out two potentially redeemable villains: Luckyuro and Candelilla ; while both are evil, they seem to be more evil because they feel it's what they should be as Deboth than anything else : but as the Joy knight and fun Spy, they have in them the potential of stopping being evil and follow their true nature.
After all, Torin is evidence that being Deboth and good is possible.
Torin was evil until he was touched by the beauty of Earth and dinosaurs ; perhaps Lucky and Candy might have their heart touched as well, since episode 38 for Lucky and episode 40 for Candy have shown they can show a soft side, even in front of their enemies (Amy for Lucky, Nossan for Candy)
