Please, Just Believe MeEpisode 4

In the kingdom of Atlantis, Queen Blair uses a "Truth Circlet" to discipline her twin daughters. The manipulative Mia repeatedly frames her honest sister, Elise, who suffers relentless magical punishment because her circlet falsely registers lies. Tragically, Elise dies in agony after her pleas for help are ignored, leaving her spirit to linger. When her decaying body is finally discovered, the circlets are revealed to be cheap human toys. Consumed by extreme regret, the Queen leaps to her death, while Elise's soul leaves the cruel royal family behind.
