It's the end of the 19th century in England...
Illuminating the nighttime streets of London covered in thick fog are gas lamps and the moonlight from between clouds.

Ladies and gentleman, be careful on the streets at night.
Things like scoundrels and mysteries hiding in the streets might be aiming at you.

Cases too large for the highly prided English police force Scotland Yard are overflowing the streets.
If you happen to get caught up in an incident...please prepare yourself to accompany it.

A great detective with skillful intellect.

A bold and fearless phantom thief.

Now then, if Big Ben's ringing echoes across the streets of London, the curtain will open on love and adventure!

A young heiress who has been raised by her dearest butler since she was a small girl. Upon her debut into high society, she receives a letter of recommendation from the Queen of England to a famed school for detectives.

Subject ofDiscrimination
Voiced byMiura Hiroaki


Hobbies: Calligraphy
Adores: Sushi and Matcha Tea

An exchange student and a brilliant detective in his own right, even if he has yet to reach the same heights as Holmes Jr. Though he is strict towards others, he is no-less strict towards himself, immediately taking up the position of class representative to further his studies whilst keeping a watchful eye over his schoolmates' behaviour.

To strive for betterment in both body and mind is the ultimate goal for him; yet he has still lived a sheltered life, having had no significant experience with women, and as such is oftentimes at a loss when interacting with them.

Subject ofDiscrimination
Voiced bySuzuki Chihiro


Talents: Boxing
Adores: Tea (Prince of Wales)

The son of London's most legendary detective. He takes after his father in many ways—his superior intellect being one, and his stubbornness being another. Herlock's proclivity for getting in the last word and mockery of others can grate on those around him, and though he is quite clever, he himself is unaware of the extent of his behaviour.

As he is a man of logic and reason, he disapproves of Lady Whiteley's more intuition-based approach, and he has no issue voicing as much.

Nakazawa Masatomo (The Crown PSV remake)


Hobbies: Hunting
Adores: Blackberry Fool

A man of two sides like Lupin Jr., and yet not a man of two faces, for he remains withdrawn no matter the situation. His mannerisms and background as an East Ender have created a natural barrier with his schoolmates, who all perceive him as different—unfortunate, as there could be those nearby who would sooner think him misunderstood.

Or it could be he isn't misunderstood at all; though his identity remains unknown, he is none other than the Ripper who terrorises London's streets. What brings him to commit these atrocities? Curiosity may grant answers, but it may also lead to Lady Whiteley's downfall.

Hobbies: Chess
Adores: Flapjacks

By day he's a meek, dangerously clumsy student by the name John Lupine, but by night, he assumes his true identity: Jean Lupin, Gentleman Thief. He revels in stealing countless treasures and has done well to live up to the master that his father is and more. Though pretentious once the sun goes down and the mask comes off, he does seem to be a man of good character at heart.

He also enjoys toying with Lady Whiteley as much as he enjoys thievery, and she has yet to decide if the pretty words he spouts upon their meetings ring false or true.

Yamaya Yoshitaka (The Crown PSV remake)


Hobbies: Reading (Detective Fiction)
Adores: Monaka

A government-sponsored exchange student and assistant to Akechi. Kobayashi's a doer before he is a thinker, though this does not mean he is lacking academically. He is fascinated by the endless wonders of London, studying its technology and culture with a hungry energy. Thankfully, his friendly nature allows him to adapt well to any situation this new world presents him.

As his name implies, he is connected to a certain well-known boy detective.

Yoshioka Maya (The Crown PSV remake)


Hobbies: Making clothes
Adores: Maids of Honour

A fellow schoolmate who attends Harrington Academy with Lady Whiteley. Marple carries an air of dollish refinement upon first sight—and upon second, an air of someone completely unaware of how odd she is to the people around her. She is blunt with grace, helpful as she is critical, and worldly in intelligence yet constantly off in her own world. There is no questioning her passion for tea and snacks, however. To her, nothing ever good comes from being hungry, and a fellow appreciator of a fine lunch is a friend for life.

She adores her grandmother, a well-known detective in her own right, and often speaks of their life together in the countryside.

Shirai Yuusuke (The Crown PSV remake)


Hobbies: Horseback-riding
Adores: Welsh rarebit

The son of Doctor John Watson. Watson is a man of action, often jumping headfirst into a situation no matter the danger. This would normally be a cause for concern, but his reputable physical strength helps to counterbalance any difficulties that might come his way. He's also quite experienced in playing the sweetener to Holmes's bitterness, and because they have a nigh-unbreakable bond of trust, that's just fine by him.

He takes a liking to the heroine from the day they first meet, and he's always more than happy to help her.

Hobbies: Cleaning
Adores: Eton Mes

The official loud-and-proud landlady of a series of flats along Baker Street, including Holmes Jr. and Watson Jr.’s shared flat. Her unusually young age in conjunction with her role may leave some sceptical, but their worries would be short-lived after meeting her; she takes all her duties seriously, happily cleaning, cooking meals, and handling the accounts for her tenants daily. She also treats them like family—particularly the boy detectives, to whom she feels an almost motherly affection towards.

She admires those in the investigative field so much that she volunteers to become Lady Whiteley’s assistant, boasting her capabilities from the rooftops to ensure she is the one and only candidate for the position.
