Description
Noah Montoir, alias Ernest Greeves in the English adaptation, works as an assistant at the Layton Detective Agency. He possesses a nervous, easily flustered personality, typically staying in the background, a stark counterpoint to Katrielle Layton's eccentricity. Ernest harbors a significant crush on Katrielle, frequently blushing when teased about it, especially by the talking dog Sherl, and is intimidated by her fierce temper.

His background reveals he is actually Miles Richmond, the eighth and last surviving grandson of the late multi-millionaire Lord Maximilian Richmond. Believing the Seven Dragons of London stole his family's diamonds after his mother's death when he was twelve, Miles adopted the alias "Ernest Greeves" from his favorite childhood book, "Ernest Shockleton, Surprise Explorer" by Richard Greeves, to conceal his identity. He enrolled at Gressenheller University on a Dark Jewel Foundation scholarship, studying plant genetics. His hobbies include flower studies and a passion for film, particularly science fiction and zombie genres.

He used the alias "Lord Adamas" as part of his plan to exact revenge on the Seven Dragons, intending to trick them into losing their money through a puzzle game at Richmond Court. "Adamas" derives from the Greek word for "unbreakable," symbolizing his resolve. However, he learned the Seven Dragons received the diamonds legitimately to repay family debts and founded the Dark Jewel Foundation for London's development. After this revelation, he abandoned his revenge, continued as Katrielle's assistant under the name Ernest, and declined a portion of the foundation's fortune, preferring it benefit the city.

Ernest first encountered Katrielle after being falsely accused of stealing research by Dr. Gene Ohm. Inspector Hastings interrogated him until Katrielle intervened, proving his innocence by revealing Dr. Ohm fed the research to goats and framed him. Grateful, Ernest begged to become her assistant, securing his ongoing role. Within the agency, Katrielle treats him like a part-time employee, often involving him in crime reenactments during investigations and sometimes subjecting him to poor treatment. His official profile describes him as initially "boring." His character remains consistent across media.
