Tantei Kageki Milky Holmes TD EP1 - The Fairies are Hiding in the Forest

In the Great Age of Idols, a mysterious phantom thief starts using their Toys to steal the singing voices of idols all across Yokohama, including all their CDs. While looking into the matter, Kokoro investigates popular idol Marine Amagi, only to find her clear of suspicion as her Toys are simply used to materialize the Elements that make up her voice. Later, during one of her performances, Marine suddenly collapses, as it is soon discovered both her singing voice and Elements have been stolen. As Marine tries to adjust to a life without singing, Milky Holmes soon deduce that the culprit is Marine's manager, who has been possessed by one of Marine's elements, Melodia, who takes everyone to an alternate dimension to challenge them to a game for Marine's freedom. Despite initially falling behind, the detectives take advantage of the strange properties of the game world and win the game. Afterwards, Melodia explains that the manager isn't the true culprit who stole everyone's voices, stating she herself ended up with the manager by accident and resonated with her desires. With Melodia returning to Marine, along with some of her talent, Milky Holmes decide to help her retrieve her other missing Elements.
