Holmes, knowing that acting ability was needed to portray the difficult character. Mitani admires Yamadera for he acts the role as if he were a boy who is naive and sensitive, though he is not so in reality. Like The Three Musketeers, some voice actors play multiple roles in the show. Masashi Ebara voices Jim Moriarty, Godfrey Norton, Aloysius Garcia and Barnicot; and Yuko Sanpei voices Enoch Drebber, Helen Stoner and Henderson. In "The Adventure of the Cheerful Four", actors Masachika Ichimura and Kenji Urai, who are famous for their appearance in musical theatre, voice some puppets. Music and the opening theme Kana Hiramatsu, a member of Spanish Connection is in charge of music. Nano, a singer who also likes the series Sherlock Holmes, performed and wrote the lyrics of the opening theme, "Scarlet Story", that deal with A Study in Scarlet. Nano tries to express the inner pains of Holmes who always searches for the truth. The show is produced by using prescoring, and projection mapping is used in the title sequence that describes "The Adventure of the Dancing Men". Playfulness As well as Mitani's other works, playfulness is included in the show. For example, the episode based on The Sign of the Four is adapted into a musical play; each speckle on a snake that appears in "The Adventure of the Speckled Band" has the shape of crocus, the flower Holmes mentions in the original. Besides Holmes's violin is on the shelf for personal belongings near his bed. Some words and conversation in the series seem to reference the series, Sherlock.
