10 years ago
When the Seven Deadly Sins was framed as criminals by the Holy Knights, Diane hid in the Forest of White Dreams and forced the imps to serve her, lest she go on a rampage.

Forest of White Dreams Arc
When Meliodas, Hawk and Elizabeth entered the Forest of White Dreams looking for a member of the Seven Deadly Sins, the Imps, thinking they were Holy Knights, tried to stop them by impersonating Hawk. However, Meliodas punched all the imps, including the real Hawk, which caused them to impersonate Elizabeth. Posing as Elizabeth, they tried to capture him but he was able to evade all of them. They said that will do anything to prove that they are the real Elizabeth, and the young man, after playing with that declaration a bit, tells them to jump as high as possible. All of the Imps did so, but not the real one as she was embarrased, since Meliodas had stolen her panties before. He then quickly defeats all of the Imps.

The imps quickly ran toward Diane, leading the three toward her, apologizing that they let a Holy Knight come through. After Diane decided to leave with Meliodas, the Imps where relieved, since they could finally live in peace after ten years.
